▼ Theranostics is the ability to diagnose with greater
detail to disease properties and tailor specialized therapeutic
regiments to a patient's unique case. Advancements in nanoparticle
synthesis for controlled material properties and further
functionalization make the nano-scale materials promising
candidates as a theranostic platform for predictive medicine, early
detection, targeted therapy, and diagnostic monitoring. Here we
examine
iron oxide, gold-silver alloy, and gold-
iron oxide
dumbbell-like heterostructure nanoparticles for their combined
diagnostic and therapeutic application.
Iron oxide nanoparticles are used clinically as MRI contrast
agents and also provide a platform for functionalization and
further application of their magnetic properties. We examine the
targeting of
iron oxide to tumor vasculature using the tumstatin
peptide in a three-dimensional in vitro tumor model and observe the
therapeutic heating abilities in an alternating magnetic field.
Surface enhanced fluorescence from nano-sized metal materials
occurs through near-field coupling of the local electromagnetic
field. We focus on controlling the surface plasmon resonance of
AuAg alloy nanoparticles (AuAgNP) with a tunable method for
transferring energy with fluorescent proteins. We examine the
synthesis, surface modification, and localization of AuAgNPs to
protein targets. We use fluorescein isothiocyanate as a model
fluorophore to measure optimal energy transfer conditions. We
examine green fluorescent protein as a target protein fluorophore
for the protein model. Determination of alloy content, distance
control, and targeting abilities for enhanced fluorescence can
optimize current fluorescence imaging techniques and quantitative
assays with greater sensitivity.
Advanced hetero-structure nanoparticles offer added material
properties and chemical functionalization over single component
nanoparticles. We examine the controlled diagnostic and therapeutic
capabilities of the dumbbell-like hetero-structure of gold-
iron
oxide nanoparticles for targeted in vivo pancreatic cancer MRI
enhancement.

▼ A classical molecular dynamics (MD) simulation has been used to investigate the adsorption and tribological performance of hydrocarbon lubricant between different iron and iron oxide surfaces. A realistic all-atom model of alkane was employed using the COMPASS force field (FF) while the relaxed surfaces and an effective force field for interactions between surface and lubricant were obtained from ab-initio calculations. A comparative analysis of adsorption of six n-alkanes (CnH2n+2, n = 4, 6, 8, 10, 12, 16) on Fe(110), FeO(110), and Fe2O3(0001) and thin film lubrication of hexadecane between Fe(100), Fe(110), Fe(111), FeO(100), FeO(110), FeO(111), Fe2O3(001), and Fe2O3(012) surfaces has been carried out. A quantitative surface parameterization was introduced to investigate the influence of surface properties such as crystalline structure, surface corrugation, and crystal plane on the structure, rheological properties, and tribological performance of the n-alkanes. The effects of working conditions such as loading pressure, shear rate, and temperature are also considered.
The results show that alkane molecules orient randomly on Fe(110) and Fe2O3(0001) surfaces but they preferentially orient in (010) direction on FeO(110) at low temperature. Additionally, alkanes adsorb physically on iron oxides, in the following decreasing order Fe(110) > FeO(110) > Fe2O3(0001). The adsorption energies per saturated carbon site decrease with an increase of molecular chain length and this propensity is similar for different surfaces. In contrast, the saturated carbon density is insensitive to the surface potentials and shows an increasing trend for short alkane chains but it remains steady for longer chains. Although the wallfluid attraction of hexadecane on pure iron surfaces is significantly stronger than its oxides, there is a considerable reduction of shear stress of confined n-hexadecane film between Fe(100), and Fe(110) surfaces compared with FeO(110), FeO(111), Fe2O3(001), and Fe2O3(012). It was found that, in thin film lubrication of hexadecane between smooth iron and iron oxide surfaces, the atomic roughness plays a role more important than the wall-fluid adhesion strength.

▼ The Permian White Rim Sandstone of southeast Utah is a distinctive, porous and permeable, white-colored unit surrounded by fine-grained red beds. In the Elaterite Basin, the White Rim Sandstone is well exposed and acts as a reservoir for tar. White Rim deposits are dominantly eolian in origin, but a thin (0.5-6 meters thick) veneer of shallow marine deposits blankets an erosional paleotopographic high in the Elaterite Basin. Superimposed on the depositional facies are three diagenetic facies that impart white (bleached), red, orange, and brown coloration in the form of disseminated and concretionary iron cement. A yellow alteration zone extends up to 20 meters (32 ft) into the underlying Permian Organ Rock Shale and overlying Triassic Moenkopi Formation. Diagenetic coloration is used as a physical proxy for fluid flow that records discrete stages of diagenesis and highlights depositional heterogeneity on multiple scales. Field, petrographic and geochemical analyses indicate that the White Rim Sandstone underwent three diagenetic stages: (1) early oxidation of the reservoir and precipitation of iron, (2) iron mobilization (bleaching) and reprecipitation of pyrite cement by hydrocarbon migration through the reservoir, and (3) oxidation of pyrite to iron oxide minerals. Field and petrographic observations, and quantitative permeability analyses indicate four scales of heterogeneity exist in the White Rim Sandstone in order of decreasing size: (1) depositional unit, (2) bed-set, (3) internal lamination, and (4) depositional grain-texture scales. Reservoir heterogeneity is highly dependent on grain packing. Authigenic cement phases also act as a record of reservoir conditions through diagenesis, providing indirect information on pH, reservoir compaction and fluid interactions. This study has three broad applications to understanding subsurface fluid behavior. (1) The physical diagenetic records provide insight into the history of hydrocarbons in a porous and permeable sandstone, and can be used in petroleum exploration to help determine hydrocarbon migration timing and pathways. (2) The mineralogic and textural characteristics of authigenic cement phases help to assess the complex history of White Rim Sandstone diagenesis through deep time. (3) Secondary iron precipitation highlights large- and small-scale heterogeneity that must be well understood for applications of CO2 sequestration in similar eolian reservoir units.

▼ Magnetic iron oxide nanoparticles have drawn
tremendous attraction from both fundamental aspect as well as
applications in biomedicine such as magnetic bio-separation,
detection of biological entities, magnetic resonance imaging,
magnetic fluid hyperthermia and targeted drug delivery due to their
fascinating magnetic properties. These properties of iron oxide
nanoparticles can be tuned by modifying their phase, size, shape
and surface coating of the nanoparticles. In the present thesis,
synthesis of iron oxide nanoparticles with different morphology and
their surface coating/functionalization were carried out. The
structural, morphological, vibrational, magnetic and optical
properties of these synthesized products were characterized by
using X-ray diffraction (XRD), field emission scanning electron
microscopy (FESEM), high-resolution transmission electron
microscopy (HRTEM), microRaman spectroscopy, Fourier transform
infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM),
ultraviolet-visible spectroscopy (UV-Vis) and photoluminescence
spectroscopy (PL). In the first part of the thesis deals with
synthesis and characterization of iron oxide (hematite and
magnetite) nanoparticles with different morphology. Hematite
nanorods were synthesized by reverse micelles method using
cetyltrimethyl ammonium bromide (CTAB) as a surfactant and calcined
at 300 °C. Nanorods have hexagonal crystal structure with diameter
of 30-50 nm and length 120-150 nm. A weak ferromagnetic behavior
was observed with saturation magnetization (Ms) of 0.6 emu g-1 and
coercive force (Hc) of 25 Oe. Ferromagnetic and#945;-Fe2O3
nanoparticles were synthesized by gel evaporation method in air at
300 and#8304;C. The average size of the as synthesized
and#945;-Fe2O3 nanoparticle was estimated to be 30 nm and the
particles were of good crystalline nature. The ferromagnetic
properties of the nanoparticles are due to the existence of
and#947;-Fe2O3 phase along with and#945;-Fe2O3.

Mechanisms of brain iron homeostasis involved in Parkinson's disease.

▼ Parkinson’s disease (PD) is a neurodegenerative disorder characterised by motor deficits accompanying degeneration of Substantia Nigra (SN) neurons. Although familial forms of the disease exist, the cause of sporadic PD is unknown. Symptomatic treatments are available for PD, but there are no disease modifying therapies. The degenerating SN exhibits iron accumulation, commonly thought to participate in neurodegeneration. The cause of iron accumulation in PD has not been established; hence, the aim of this thesis was to investigate the mechanism of iron accumulation in PD.
A battery of proteins regulates cellular iron import, storage and export. Described in this thesis is an investigation of possible mechanisms of iron elevation in PD. The experiments included in this thesis involved analysis of post mortem tissue, as well as tissue culture and animal models. It was hypothesised that altered cellular uptake or release of iron contributes to iron pathology in PD.
Evidence obtained in this investigation was used to argue that stimulation of the cellular iron import pathway cannot alone account for iron accumulation in PD. It was therefore hypothesised that a failure of iron export mediates iron accumulation in PD. Proteins involved with iron export (Ferroportin, Ceruloplasmin, amyloid precursor protein (APP), transferrin) were found to be decreased in PD afflicted human brain, and in an animal model of PD, providing evidence for disturbed iron export activity in PD. In pursuit of iron export correction, peripheral administration of transferrin was investigated as a potential iron attenuating therapeutic. In addition, the amine oxidase activity of APP was explored, with implications for PD.
It was hypothesised that in PD, there is disturbed regulation of the proteins that serve to maintain iron homeostasis. By surveying brain tissue, iron levels were found to be correlated with several iron associated proteins in control tissue, however, in contrast, almost all iron-associated proteins lose their correlation with the iron levels in PD tissue. This possibly suggests that in PD, the brain becomes insensitive to the cellular iron content, thus making it susceptible to iron accumulation through loss of homeostasis.
A possible mechanism for iron dyshomeostasis is via altered Nitric oxide (NO) signalling. NO is a cell-signalling molecule extensively linked to PD; NO is elevated in PD and thought to participate in nitrative stress by reaction with the superoxide molecule to form the highly reactive peroxynitrite radical. NO also disturbs iron regulation by manipulating iron responsive proteins 1 and 2, as well as hypoxia inducing factor 1α which, in concert, govern iron homeostasis. It was hypothesised that NO elevation in PD is the mechanism for perturbed regulation of iron. Preventing NO induction in an animal model of PD restored iron…

▼ Nowadays, enormous research efforts focus on the diagnosis and therapy of different types of sarcomas, which are rare but malignant cancers. The application of nano-science in cancer therapy has become one of the most attractive tools in scientific research because of its versatility in diagnosis and treatment. In particular, multifunctional and multimodal magnetic
iron oxide nanoparticles can offer solutions in diverse areas of sarcoma, as one of the most desirable noninvasive magnetic resonance imaging (MRI) contrast agents, as well as drug, ligand and gene nanocarrier. It is also an outstanding hyperthermia agent via generating local heat under an alternative magnetic field.
Iron oxide nanoparticles are renowned because of their low toxicity and suitability for treatment and diagnosis of different types of cancers; however, in some cases,
iron oxide nanoparticles may result in severe damage of DNA, protein, and lipid. To our knowledge research investigating the cytotoxicity effect of
iron oxide nanoparticles with different physiochemical characteristics in sarcoma is limited, which presents some major issues that need to be carefully considered. In this study, we initially prepared desirable
iron oxide nanoparticles with hydrothermal synthesis and thermal decomposition methods. We modified the aforementioned methods in order to create a desirable range of size of magnetic nanoparticles for bio application (200, 100, 20 and 10 nm). We, also, modified the surface of nanoparticles with different types of coatings (polyethylene glycol (PEG), D-glucose (DG) and silica) under mild conditions to increase their bio-compatibility, bioavailability and colloidal stability. Various methods were used to illustrate and quantify cellular uptake of magnetic nanoparticles in sarcoma cell lines. Finally, the safety of the nanoparticles uptake on diverse human sarcoma cell lines was investigated and found that the readily available
iron oxide nanoparticles can be safely taken up by synovial sarcoma and liposarcoma cell lines in the selective histological tumor types; however, they seem highly toxic for fibrous histiocytoma and fibrosarcoma.

▼ Iron oxyhydroxide and
oxide nanoparticles have shown potential capabilities in the field of nanoelectronics, clean energy, and biomedicine. The studies of the physical and chemical properties of these nanomaterials are important for understanding the formation and growth mechanisms, interface interactions, and surface behaviors control for functional properties and potential applications.Various
iron oxyhydroxides/oxides were primarily investigated in this thesis, including Goethite (α-FeOOH) and Akaganéite (β-FeOOH) one-dimensional (1-D) nanostructures with various aspect ratios under ambient conditions. These
iron oxyhydroxide materials are thermally and chemically unstable, therefore can easily convert into hematite (α-Fe2O3) and magnetite (Fe3O4) by calcinations and/or chemical reduction, respectively.To further enhance the functional properties and performance, the nanocomposite composed of the core
iron oxyhydroxide/
oxide particles and polymer or metal coatings were also investigated. The direct deposition of metal nanoparticles (e.g., gold and platinum) was firstly studied. This method will produce stable nanoparticles, which will be useful for chemical adsorption and catalysis. The synthesis of surfactant, polymer, and silica coated nanocomposites was also considered. This procedure is often used in the low temperature applications because the core-shell structure is favorable especially in the areas of drug-deliveries, biological/chemical separations, and sensors.In order to gain a fundamental understanding of the nanoscale system, it is important to use multiscale theoretical methods validated by experimental techniques. Our research method involves the use of various microscopy, diffraction, and spectroscopy techniques to obtain experimental results. The data is further understood through a computational simulation, which allows further insights into fundamental theories of nanoparticle interactions.

▼ Ultrasonic humidifier use is a potential source of human exposure to inhalable particulates. This paper focused on the behavior of insoluble
iron oxides particles, and aluminum
oxide particles in ultrasonic humidifiers. 10 mg/L Fe
oxide particles and 5 mg/L Al
oxide suspension solutions were added into tap water, as fill water for ultrasonic humidifiers operated for 14 hours. Denser, heavier particles of approximate 1.5 um diameter of
iron or aluminum oxides accumulated in the humidifier reservoir. Smaller, suspended metal
oxide particles of 0.22-0.57 um diameter were emitted as aerosols from humidifiers. Soluble anions and cations in tap water were present in the aerosols emitted from humidifiers. The results indicate that if suspended particles and dissolved minerals are present in source water, they will be transported in aerosolized waters.

▼ Magnetic nanoparticles are effective in a range of biomedical applications including magneticresonance imaging (MRI) contrast enhancement. The efficacy of nanoparticles ascontrast agents depends mainly on the surface chemistry and magnetic properties of theparticles, with a large magnetic moment inducing efficient transverse (T₂) relaxation ofprotons. This results in improved negative enhancement of MRI contrast on T₂ weightedsequences.
Iron oxide nanoparticles (FeOx NPs) have been used in MRI for 20 years andare the only commercially available T₂ contrast agents. A significantly larger magneticmoment can potentially be achieved with
iron nanoparticles (Fe NPs), but developmenthas been hampered by difficulty in preparing stable particles. In this study, stable Fe NPwere prepared by a novel, simple, synthesis and compared with FeOx NP as T₂ contrastagents in a range of MRI-based biomedical applications.The effectiveness of Fe NPs versus FeOx NPs to negatively enhance MRI contrast onT₂ weighted sequences was first examined in vitro. The Fe NPs and FeOx NPs werecharacterised by electron microscopy and found to be of similar size (16nm). The Fe NPspossessed a core of highly magnetic α-Fe inside a 3nm shell of FeOx of the same crystalstructure as the pure FeOx NPs. Both types of NP were coated with the same molecule,DMSA, to produce aqueous dispersions with similar hydrodynamic particle sizes andpharmacokinetics. When dispersed in gels and examined by MRI, the Fe NPs were foundto produce more than twice the amount of T₂ contrast change per unit concentrationrelative to FeOx NPs. When cells were labelled in vitro, Fe NPs produced greater T₂contrast enhancement in all cell types tested, whilst there was no significant difference in the uptake of
iron or the cytotoxicity between cells labelled with Fe or FeOx NPs.To assess the clinical applicability of the nanoparticles in vivo, FeOx NPs and Fe NPswere administered to mice and MRI experiments were performed at 1.5 T. Contrast effectsof the NPs were examined in the liver, spleen and lymph nodes, as tissues in theseorgans are rich in phagocytic cells and have a strong tendency to take up circulatingNPs. In all three organs studied, the Fe NPs produced noticeably darker contrast thanthe FeOx NPs, providing twice the contrast improvement.One of the most intensely researched applications of magnetic nanoparticles in MRI is improving detection of cancer in the lymph nodes. To model the size and NP uptake ofsmall lymph node metastases in humans, a mouse model was developed by injecting 4T1breast cancer cells directly into the mouse spleen. Analysis of mice bearing 4T1 tumoursperformed at 1.5 T showed that Fe NPs produced better contrast than FeOx NPs andimproved the detection of small tumours in the spleen as determined by two blindedradiologists. Indeed, the heightened sensitivity and specificity improved the threshold ofcancer detection on previous studies performed at 1.5 T.It was then examined whether the improved T₂ contrast could enable new MRI applicationsin vivo. A novel…

Geometric and Electronic Structure Sensitivity of Methyl and Methylene Reactions on α-Cr₂O₃ and α-Fe₂O₃ surfaces.

▼ Structural and electronic effects in hydrocarbon reactions over metal oxides have been examined by comparing the reactions of methyl (-CH₃) and methylene (=CH₂) fragments on three different
oxide single crystal surfaces: α-Cr₂O₃(101̅2), α-Cr₂O₃(0001), and α-Fe₂O₃(101̅2). The intermediates have been generated through the decomposition of halogenated hydrocarbons.
The primary reactions of methyl and methylene over α-Cr₂O₃ are methyl dehydrogenation to methylene, and methylene coupling (C-C bond formation) to ethylene (CH₂=CH₂). The different surface geometric structures of α-Cr₂O₃(101̅2) and (0001) lead to an increase in the activation barrier for methylene surface migration, a critical step in the coupling reaction, of 5.9 kcal/mol over the (0001) surface. For methyl dehydrogenation, differences in the local site pair (cation/anion) geometry and the proximity of surface lattice oxygen to the methyl group do not result in a significant difference in the barrier for dehydrogenation, suggesting that the surface anions play a minor role in the dehydrogenation of methyl on these surfaces.
Electronic differences in the Fe³⁺ (𝑑⁵) and Cr³⁺ (𝑑³) cations on structurally-similar α-Cr₂O₃(101̅2) and α-Fe₂O₃(101̅2) surfaces lead to major differences in reaction selectivity. α-Cr₂O₃(101̅2) is nonreducible under the reaction conditions of this study, but α-Fe₂O₃(101̅2) is highly reducible due to the difference in the d electron configuration. Hydrocarbons are formed over α-Cr₂O₃(101̅2), but nonselective oxidation products (CO₂, CO, H₂O) are formed over the stoichiometric α-Fe₂O₃(101̅2) surface along with surface reduction. Reduction of the α-Fe₂O₃(101̅2) leads to a shift in the product selectivity towards formaldehyde (CH₂O) and ethylene.
For the limited number of systems examined in this study, examples of geometric structure sensitive (methylene coupling) and structure insensitive (methyl dehydrogenation) reactions have been found on α-Cr₂O₃, and electronic effects are observed for the reactions on α-Cr₂O₃(101̅2) and α-Fe₂O₃. For the structure sensitive reaction, the differences in surface geometry impact the reactions kinetics over Cr₂O₃ but not the types of products formed, while the electronic differences give rise to dramatic changes in the selectivity associated with the very different products formed over α-Cr₂O₃(101̅2) and α-Fe₂O₃(101̅2).

▼ This study examines the use of unmodified magnetite nanoparticles (Fe3O4 NPs) for selective extraction and enrichment of the catecholamines dopamine (DA), noradrenaline (NE), and adrenaline (E), prior to analysis using capillary electrophoresis with UV detection. Coordination between Fe3+ on-the-surface Fe3O4 NPs and the catechol moiety of catecholamines enables Fe3O4 NPs to capture catecholamines from an aqueous solution. We obtained maximum loading of catecholamines on the NP surface by adjusting the pH of the solution to 7.0. In addition, catecholamine loading on the Fe3O4 NPs increased in conjunction with NP concentrations. Ligand exchange found H3PO4 to be efficient in the removal of adsorbed catecholamines on the NP surface. Adding 1.2% poly(diallyldimethylammonium chloride) to the background electrolyte caused efficient separation of the liberated catecholamines with baseline resolution within 20 min. Under optimal extraction and separation conditions, the limit of detections at a signal-to-noise ratio of 3 for E, NE, and DA were 9 nM, 8 nM, and 10 nM, respectively. Significantly, we successfully used the combination of a phenylboronate-containing spin column and the proposed method to determine the concentrations of NE and DA in urine and the content of NE in Portulaca oleracea L. leaves.

▼ The microbial ferrous-iron oxidation process plays a significant role in bioleaching, providing
ferric-iron (Fe3+) − a strong oxidising agent for the dissolution of most sulphide minerals. An
extensive literature review has shown that several studies have been carried out on microbial
ferrous-iron oxidation, mostly in stirred tank reactors and in conditions close to optimum.
However, limited studies have been carried out on this subject in the context of heap
bioleach situation. Despite the fact a packed column system may be used to represent heap
bioleaching, most of the studies on microbial ferrous-iron oxidation in such systems were
carried out under flooded/fluidised conditions which do not adequately represent solution flow
dynamics in a heap system.
The microbial ferrous-iron oxidation kinetics of Leptospirillum ferriphilum were studied at
substrate loading rates of 0.17 – 0.5 g.L-1h
-1 (dilution rates 0.033 – 0.1 h-1). The study was
conducted in a packed column with a view to investigating the kinetics in a system which
simulates the solution flow dynamics of a typical heap bioleach operation. Glass marbles, 15
mm in diameter, were used as reactor packing. The microbial oxidation kinetics were
investigated in a continuous mode at the desired loading rates. The pH of the bioreactor was
maintained at pH 1.45 ± 0.05 and the aeration at 15 mL.s-1. Both Monod and Hansford
models were used to describe the biooxidation kinetics.

▼ Surface modification of electrodes becomes a powerful process to improve the performance
of organic electronic devices such as organic light emitting diodes (OLEDs)
and organic photovoltaic cells (OPVs), boosting their further commercialization. Effective
improvement can be achieved by introducing several types of nanoparticles
onto the electrodes. Magnetic fields also have influence in the organic electronics,
due to charge transport mechanisms of organic semiconducting materials. Therefore,
magnetic nanoparticles are of particular interest.
Magnetic γ-Fe2O3 nanoparticles have been produced using diblock copolymer reverse
micelles method. The processes were elucidated in detail by Raman spectroscopy
to reveal the iron oxide evolution. Compositional and structural information of individual
γ-Fe2O3 nanoparticles were also characterized thoroughly by transmission
electron microscopy (TEM) equipped with energy-dispersive X-ray spectroscopy (EDX)
and electron energy loss spectroscopy (EELS), while their magnetic properties of the
nanoparticles arrays were also evaluated by superconducting quantum interference
device (SQUID) magnetometer. The low temperature annealing process was developed
to facilitate the incorporation of γ-Fe2O3 nanoparticles in practical devices. Introducing
γ-Fe2O3 nanoparticles onto the anode of basic OPV devices showed a positive
effect on performance during the preliminary test.
By using several methods, dispersion of γ-Fe2O3 nanoparticles can be tuned, examined
by disLocate which is a comprehensive suite of tools for quantitative dispersion
analysis. Additionally, the size of the nanoparticles can be changed simply by changing
the loading ratio of FeCl3 below the maximum loading which was determined by
quantum mechanical mapping using atomic force microscopy (AFM-QNM). With
high control in terms of size and dispersion, the magnetic γ-Fe2O3 nanoparticles are
ready to be employed to study the surface modification and magnetic effect on organic
electronic devices.

▼ Forest soil phosphorus (P) chemical behavior was evaluated in some mid-rotation
fertilized loblolly pine (Pinus taeda L.) plantations in East Texas, that differed in their
site drainage characteristics. Forest floor mass and carbon content in the forest floor
were determined. Total P (PT) in the forest floor, and total and Mehlich-1 P and citratedithionite
(CD) and acid ammonium-oxalate (AAO) extractable P, Al, Fe, and Mn within
the mineral soil upper 100 cm were determined. Colorimetric determination of AAOand
CD-extractable P by the molybdenum blue ascorbic acid method, without the use of
pre-digestion, was assessed by an automated continuous flow injection system.
Phosphorus distribution between different operationally defined solid phases and its
relationships with CD and AAO extractable Mn, Al, Fe among depth, site, drainage class
and treatment were evaluated. Soil P forms were highly correlated with
iron oxides
across sites, drainage classes, treatments, and depth intervals with significant differences
in P content and distribution in the soil profile and solid phases among drainage classes.
Soil P distribution patterns differed among drainage classes, yet it followed the
distribution of the
iron oxides.
Iron oxideâÂÂs role as a sink for soil P was higher in the
well-drained compared to the poorly drained sites. Amorphous phases of
iron oxides
were higher in the poorly drained sites and dominated the role of
iron oxides as a sink
for P under the poor drainage conditions. Fertilization resulted in significantly higher
forest floor mass, P content in the forest floor, and total P (PT) and CD-extractable P (Pd)
in the soilsâ upper 10 cm. The treatment effect on P in the forest floor, and on PT and Pd
in the upper 10 cm of the mineral soil was equivalent to 6, 19, and 11% of the applied P, respectively. AAO-extractable P was highly correlated with Mehlich-1 P in the
fertilized plots. Treatment and site drainage class effects on P accumulation in the
different solid phases in the mineral soil and in the forest floor and the potential
contribution of these pools to P availability in subsequent rotations, following
clearcutting, are discussed.

▼ Magnetic
iron oxide nanoparticles (MIONs) have unique physical-chemical properties for a wide range of biomedical applications, including targeted drug delivery, multimodality molecular imaging, thermal therapies, and biomarker detection. In this study, I optimized MIONs for different biomedical applications. First, to improve the efficacy of cancer immunotherapy for solid tumors, I increased endocytosis of MIONs into T cells using cell penetrating peptides to enable better in vivo imaging and targeting. Secondly, to facilitate hyperthermia therapy and anti-cancer drug delivery by heat-triggered release, I coated MIONs with mesoporous silica and demonstrated enhanced colloidal stability and heating efficiency. Thirdly, to measure the levels of trace biomarkers for early cancer detection with high sensitivity, I quantified pancreatic cancer biomarkers in patient serum samples using europium-doped

▼ This project was a joint venture between Loughborough University, the academic investigator, and ICI, the industrial sponsor. The aim was to develop and validate filter cycle scale-up methodologies, based on laboratory experiments at Loughborough and full-scale plant work at several ICI sites. Two ICI products, which experience processing problems during filtration, were chosen for assessment. They were a catalyst material (predominately iron oxide), processed by Synetix using rotary vacuum filters (RVFs), and titanium dioxide (TiO2) processed by Tioxide using a diaphragm filter press. A number of objectives were originally highlighted: (1) to develop and validate scale-up methodologies for a pressure filter and vacuum filter; (2) to develop models required to provide accurate predictions of filter performance; (3) to produce PC simulations of RVF and diaphragm filter press; (4) to produce reliable filter cycle data for process feeds of interest to ICI.

▼ Stainless steels differ from
iron in that chromium content allows for the
formation of a passive
iron-chromium
oxide film which is only nanometres
in thickness, offering protection from the environment. While the
composition of this
oxide layer has been established, the mechanism of
its formation is not well understood. In particular, the threshold level of
chromium for
oxide formation is significantly lower then the chromium
content of the alloy itself. We present a Cahn Hilliard type analytical
model that relates the onset of passivation to an instability which leads
to a phase segregating current above 17% Cr in a bulk alloy. Proposing
that this current could lead to Cr enrichment at a surface, we compare
atomistic simulations with and without a surface driven Cr current. We
implemented a kinetic Monte Carlo algorithm with extensions to allow
for vacancy assisted nearest neighbour migration in a body centered cubic
alloy, tracking a surface, dissolution and surface passivation. We compare
the time evolution of Fe dissolution rates, Cr surface enrichment and the
threshold for passive film formation and find that the Cr current has a
significant impact on each of these properties.

▼ In the present study we report the synthesis and characterization of
iron oxide magnetic nanoparticles doped with zinc in an attempt to enhance the magnetic properties. The nanoparticles were prepared via the co-precipitation route and capped with 3-phosphonopropionic acid (3-PPA). The amount of zinc dopant was varied to yield nanoparticles with the general formula ZnxFe3-xO4 (x=0, 0.1, 0.2, 0.3, 0.4). Characterization was carried out using high resolution transmission electron microscopy (HRTEM), X-ray diffraction spectroscopy (XRD), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and superconducting quantum interference device (SQUID) analysis. Results from HRTEM, XRD and SQUID confirm that doping took place and x=0.2 was found to be the doping limit for these nanoparticles with a maximum size of 10.73 nm and saturation magnetization of 73.37 emu/g. The EDS further confirmed successful doping with zinc, while FTIR and TGA confirmed successful capping with 3-PPA. Despite agglomeration at all doping levels, these nanoparticles show great potential for application in breast cancer diagnostic studies.

▼ Processes that occur at the nanoscale are the foundational building blocks of our world. As such, there is considerable interest in ways to study and manipulate matter at this scale, with applications in biomedicine and other fields. DNA origami has emerged over the past decade as a promising technology for nanofabrication, offering the capacity for precise and tunable nanoscale synthesis while maintaining the ease and scale of bottom-up self-assembly. The goal of this work is to develop novel ways in which DNA origami can be used to manipulate nanoscale processes. To this end, I developed a single DNA origami nanorod which is used in two distinct studies, highlighting the multifunctionality of this structure. I first investigated the effect of
iron oxide nanoparticle clustering on MRI contrast generation by organizing particles in precise patterns on the nanorod. I found that small changes in the number of attached
iron oxide nanoparticles lead to significant enhancement in T2 relaxivity, while inter-particle spacing has a minimal effect. In the second part of thesis, I developed the first DNA origami molecular motor, which converts chemical energy into mechanical activity and demonstrates autonomous directed motion over micron distances. By leveraging the unique addressability of DNA origami, I found that these motors predominately exhibit a rolling motion and that this behavior can be tuned via small alterations to the nanorod. Combined, this work demonstrates two novel applications for DNA origami nanostructures. We expect this work will serve as an initial platform for further studies and open up a range of new possibilities for the use of DNA origami as MRI contrast agents and molecular motors.

▼ Until recently, gold was viewed as catalytically inert, due in large part to the noble character of bulk gold. However, when gold is finely dispersed on a suitable support, the material is often endowed with high catalytic ability for a number of reactions, most notably, CO oxidation at ambient conditions. In this thesis, isotopic oxygen exchange is used to probe the reactivity of surface oxygen, with a view to correlate these results with the CO oxidation results and better understand the surface processes governing CO oxidation. In this study, both MgO and Fe₂O₃ have been chosen as supports for gold. The first one is known to exchange oxygen well and Fe₂O₃ as a support is associated with high activity for CO oxidation at room temperature. Both sets of catalysts have been prepared by either co-precipitation or impregnation and pre-treated by calcining in air at 435°C, 800°C or left uncalcined, in addition they have both been tested for their ability to exchange oxygen and oxidize CO. Results suggest a strong influence of preparation technique and support type on isotopic oxygen exchange and CO oxidation. Comparison of exchange and oxidation data suggest oxidation occurs by a non-lattice pathway. Several experiments indicate this is augmented by oxidation from the lattice in some cases. All samples have been characterised by a range of techniques aimed at elucidating the nature of their surfaces, with the aim of correlating these data with sample isotopic exchange and CO oxidation performance. These techniques include; BET surface area determination, XPS, TPR, SEM and XRD.

▼ The successful development of responsive, multimodal imaging agents required a bottom-up approach starting with the nature of the
iron oxide nanoparticles. Thee relaxivity of the nanoparticles was found to be dependent on the total anisotropy of the particles themselves, which is in turn a function of the size, shape, composition, surface coating, and interparticle distance of the nanoparticles. Responsive, monomodal imaging agents designed to respond to Cu(I) via click chemistry were found to produces significant changes in transverse relaxivity, corresponding to regime changes upon nanoparticle aggregation. These changes agreed well with theoretical modeling and laid the foundation for the subsequent design of multimodal imaging agents.The first multimodal imaging probe,
[email protected]@Ln was designed to maximize relaxivity using a
[email protected] based system. The probe was found to have high relaxivities and exhibited traditional time delayed lanthanide luminescence. The second probe, a core-shell
[email protected]@Au multimodal imaging probe was also designed. It was found that the organic intermediate layer maintain the relaxivity of the core nanoparticles, while the gold shell exhibited significant plasmonic absorbance, enabling the probes to function as multimodal imaging probes.Finally, responsive multimodal imaging probes using the previously designed multimodal imaging probes as templates were designed. By using Cu(I) induced aggregation of AuNP and MIONs, the aggregation of the probes was monitored via attenuation of the SPR absorbance and increases in relaxivity. Additional probes using
[email protected] based designs allowed for small molecule (dsDNA) detection as monitored by luminescence quenching and changes in relaxivity.

▼ Geobacter sulfurreducens is a Gram negative δ-proteobacteria with the ability to couple the internal oxidation of a carbon and electron donor with the external reduction of extracellular electron acceptors. Extracellular electron acceptors utilized by G. sulfurreducens include insoluble Fe(III)- and Mn(IV)-oxides, electrodes poised at accepting potentials, and a variety of soluble acceptors including humic acids and chelated metals. These substrates exist over a redox potential window greater than 0.5 V, suggesting that respiratory flexibility to efficiently take advantage of electron acceptors with different redox potentials would be a useful trait. The data presented within this thesis demonstrate that G. sulfurreducens uses multiple electron transfer pathways for the reduction of extracellular electron acceptors of different redox potentials.

▼ The research described in this Dissertation is concerned generally with the exploration of the potential use of lanthanide elements in nanostructured materials for the purpose of modification of the magnetic and optical properties. This is explored through a focus on the development of lanthanide-containing
iron oxide nanosystems. Our objectives of producing lanthanide containing nanostructured materials with potentially useful optical and magnetic applications has been achieved through the development of lanthanide-doped Fe3O4 and -Fe2O3 nanoparticles, as well as a unique core-shell magnetic-upconverting nanoparticle system.Necessary background information on nanomaterials, rationale for the study of lanthanide-containing
iron oxide nanosystems and context for discussion of the results obtained in each project is provided in the Introduction Chapter. The syntheses of Fe3O4 nanoparticles doped with Eu(III) and Sm(III) are discussed, along with structural characterization and magnetic property investigation of products In Chapter 2. The following Chapter expands the study of lanthanide doping to -Fe2O3, a closely related yet distinct magnetic nanoparticle system. A completely different synthesis is attempted, and comparisons between the two systems are made.The development of novel synthetic methodologies used to create such products has yielded high-quality lanthanide-containing materials and are evidenced by TEM images displaying nearly monodisperse particles in each of our efforts. The modifications to the magnetic properties resulting from lanthanide doping include theobservation of ferromagnetism in the Fe3O4 system and increased magnetic saturation of -Fe2O3 nanoparticles, and are characterized by VSM and the visual observation of magnetic alignment of products. Our efforts towards developing a novel methodology capable of producing high quality Fe3O4 nanoparticles, and subsequent characterization of products, were published in the Journal of the American Chemical Society.Optically active, magnetic, core-shell nanoparticles are investigated in Chapter 4 for the potential uses in diagnosis and treatment of cancer. This multifunctional system uses Fe3O4 as a magnetic core, shelled by upconverting lanthanide-containing nanomaterials, and is rendered biocompatible through encapsulation of the core-shell structure by a silica shell. Added functionality is achieved through amine functionalization of the silica surface, with the goal of coupling the inorganic nanoparticle with drug targeting groups. TEM results indicate successful formation of the core-shell nanoparticles, and expected magnetic and optical properties are shown by visual observation and luminescence spectroscopy, respectively.

▼ The biological interplay between Fe and NyOx is significant to both human physiology and the remediation of global pollution. The interconversion of NyOx species is primarily mediated by metalloenzymes, in which Fe plays a critical role. Due
to their critical role in biology and the environment, the study of Fe-NyOx interactions is of fundamental interest in coordination chemistry. Additionally, thiol-containing biomolecules have direct interaction with Fe-NyOx. For example, Fe(III)-NO2
complexes react with thiols to NO or HNO and the corresponding sulfenic acids. Given the complex interplay between NyOx, Fe, and thiols, there is a need to rationalize this intricate chemistry through model complexes. Our approach involves the design and
synthesis of modular non-heme complexes in which donor strength, flexibility, and secondary-sphere interactions are readily tuned. This methodology has facilitated the isolation and characterization of the first non-heme {FeNO}8 and Fe(II)(NO2)2
complexes, and allowed for the first study of their reactivity with Fe(III)-porphyrins, Fe(III)-myoglobin, thiols, and protons. From these reactivity studies we have demonstrated nitroxyl-transfer to metMb to give MbNO, thus outlining the
proof-of-principle for the rational design of metal-based HNO donors. Moreover, we have demonstrated that reactions of non-heme {FeNO}7/8 complexes with thiols ultimately leads to various dinitrosyl iron complexes (DNICs) in an oxidation state dependent
manner. These results suggest a possible route to DNIC formation from non-heme {FeNO}7/8 complexes in biology. Lastly, the development of non-heme NO2- reduction catalysts is discussed. In the presence of H+/thiols the selective and catalytic conversion
of NO2- to NO(g) is observed. However, in the presence of only thiols, a net three-electron reduction of Fe(II)(NO2)2 to the Fe(I)(NO)2 DNIC is observed, and suggests a possible role for Fe-NO2 and thiols in the formation of biological DNICs. Described
in this dissertation is the synthesis, characterization, and reactivity of a series of non-heme Fe-NOx complexes, which provides the basis for the development of non-heme NO2 reduction catalysts and Fe-based HNO donor molecules for the purpose of
cardiovascular therapies and environmental remediation.

▼ Nanoclusters with sizes of ~50nm with high NIR extinction at wavelengths beyond 800 nm are of interest in various fields including biomedical optical imaging, microelectronics, plasmonic sensors, and catalysis. Herein we report gold nanoclusters with hydrodynamic diameters of ~50 nm composed of ~10 nm primary particles. The kinetically controlled assembly of clusters occurs simultaneously with the reaction to synthesize the primary particles. The clustering is induced by attractive van der Waals forces that dominate over the steric and electrostatic repulsive forces present. Stability is provided using a single, biocompatible polysaccharide in either carboxymethyl dextran or dextran. High NIR shifts of the surface Plasmon resonance are achieved through close interparticle spacings of primary particles, deviations in morphology from that of a sphere of primaries, and the surface roughness that results from the clustering process. The cluster size is mediated by controlling the relative nucleation and growth rates of primary particles using a moderate reducing agent in NH2OH and glucose at pH 8.7. It will be shown that cluster size is also dependent on Au concentrations in solution. Maintaining low Au concentrations will allow for smaller clusters. In particular, the small size and high NIR extinction at longer wavelengths (800-1100 nm) makes these particles of interest for optical imaging applications in biology, as particles with a hydrodynamic diameter of ~50 nm have long blood lifetimes.

▼ In this study, we used neutron scattering to understand the evolution of crystal and magnetic phases of Pb or Ca doped bismuth
iron oxide. This is an interested topic have great potential for future applications, but with only few research reports. Earlier study[1] has pointed out that Bi0.9Pb0.1FeO3 consisted of long-range order R3c and Pm-3m structures. Because the radius of lead ion is larger and of calcium ion is smaller than that of bismuth ion. The bond length between irons should reflect the same tendency: longer bond length for lead doped samples and shorter for calcium doped samples. However, the neutron diffraction results do not support these assumptions. The TN temperatures go up, 708K for the BCaFO sample and 680K for the BPbFO sample, for both samples. By analyzing neutron diffraction data, we find that R3c phase dominates at room temperature while its percentage decreases at high temperature. Bond valence calculation on both Neutron and X-ray diffraction data, XRD data was taken only at 300K, show that Pb and Ca are in divalent state, therefore, we expect oxygen vacancies must appear to provide charge balance. The existence of oxygen vacancies, theFe-Fe bond lengths and Fe-O-Fe angles are found to become shorter and to close to 180o. The Fe-Fe lengths are found BPbFO>BFO>BCaFO, and the Fe-O-Fe bond angles are BPbFO>BFO~BCaFO. Similar relationships can also be observed in Pm-3m phase. According to Goodenough-Kanamori-Anderson (GKA) rule [2] , their magnetic coupling were enhanced coincides with our results, TN were enhanced in both doping.

▼ The element
iron (Fe) is essential for mammals since many enzymes require Fe as a cofactor for metabolic processes. Fe regulation is extremely important to maintain Fe homeostasis as Fe overload and Fe deprivation are cytotoxic. Fe overload can cause oxidative damage via excessive production of reactive oxygen species (ROS). On the other hand, Fe deprivation can inhibit cellular growth and lead to apoptosis.
Iron regulatory proteins (IRPs) are important for maintaining cellular Fe homeostasis. Regulation of these proteins involves the redox status of the
iron-sulphur (Fe-S) clusters of the enzyme aconitase. IRPs are very sensitive to oxidative stress. Excessive exposure of these regulatory proteins to ROS will disrupt cellular Fe regulation by inducing Fe trafficking in cells. The major cellular systems (e.g. mitochondrial respiratory chain) are dependent on Fe for their functionality. With a lack of Fe, these systems will be affected. The susceptibility of cells to oxidative damage will increase under Fe deprivation conditions. Therefore, potentially both Fe overload and Fe deprivation are beneficial for cancer therapy if they could be selectively induced within a tumour. In the present study, nitric
oxide (•NO) released by a novel photoactive agent, tDSNO, was studied as a means of selectively impairing Fe homeostasis and exacerbating the effect of Fe deprivation. The exposure to •NO was hypothesised to cause toxicity to cancer cells by exaggerating the stress conditions, which is the characteristic of both Fe overload and Fe deprivation pathways. Results showed that the exposure of breast cancer cells (MDA-MB-231) and lung cancer cells (A549) to •NO under normal Fe homeostasis conditions was unable to promote Fe overload as the intracellular Fe content did not significantly increase relative to control (p>0.05). However, the efficacy of tDSNO was potentiated under conditions of Fe deprivation. A maximum cellular death of 59.1 ± 1.2% was observed after 24 h of exposure to 40 µM of tDSNO at 37 °C (p<0.05), while under these conditions, the drug tDSNO displayed a low toxicity in cells with normal Fe homeostasis. Therefore, the toxic effect of tDSNO in cancer cells was substantially enhanced under Fe deprivation conditions. It was then concluded that this novel drug could be more effective if used in combination with Fe chelation therapy.

▼ Tehnološko inženjerstvo - Inženjerstvo materijala /
Technological Engineering - Materials Engineering
U poređenju sa fotonaponskim ćelijama,
fotoelektrohemijske ćelije predstavljaju efikasan vid pretvaranja
sunčeve energije u električnu, jer se pored energije dobija i
vodonik koji se može iskoristiti kao gorivo. Fotoelektrohemijske
ćelije sastoje se od poluprovodničke anode (p- ili n-tipa) koja
apsorbuje svetlost, pri čemu se konverzija energije odigrava na
granici faza poluprovodnik-elektrolit. U ovoj doktorskoj
disertaciji primenjena su tri istraživačka pravca za dobijanje
filmova u svojstvu fotoaktivnih anoda. Prvi istraživački pravac bio
je priprema nanočestičnog poluprovodnika - pseudobrukita, Fe2TiO5,
reakcijom u čvrstom stanju između anatasa, TiO2 i hematita,
α-Fe2O3. Analiza dobijanja najpre je praćena na tabletama radi
optimizacije sastava, temperature i vremena sinterovanja. Ispitan
je uticaj promene temperature sinterovanja (750 – 1250 C) na fazni
sastav, temperaturu faznog prelaza, morfologiju, kao i električna
svojstva sinterovanih uzoraka. Izabrane su dve oksidne smeše
maseni odnos prahova 40%α-Fe2O3/60%TiO2 (4F6T) i 60%α-Fe2O3/40%TiO2
(6F4T) što približno odgovara molskom odnosu početnih prahova
hematita i anatasa od 1:3 i 1,5:2, sa ciljem da se dobije
pseudobrukit i analizira uticaj viška anatasa. Uzorci sinterovani
na temperaturi 850 C sadržali su rutil i pseudobrukit sa rombičnom
strukturom čime je potvrđeno da gvožđe ubrzava faznu transformaciju
anatasa u rutil pri čemu se formira i pseudobrukitna faza. Dalje
povišenje temperature uticalo je na povećanje gustine uzoraka,
promene u veličini zrna i smanjenje električne otpornosti. Drugi
istraživački pravac bio je priprema elektrodnih filmova
sitoštampanjem pasti koje su dobijene mešanjem homogenizovanih
prahova sa organskom smolom (butil celuloza), rastvaračem
(terpinol) i malom količinom veziva – ROSiO2B2O3 staklo (RO-oksid
retkih zemalja). Dobijene paste deponovane su sitoštampom na
supstrat od alumine i potom sinterovane u hibridnoj peći 60 minuta
u temperaturnom opsegu 800 – 950 C. Rendgenskom difrakcionom
analizom utvrđeno je da se na 800 C formira monoklinični
pseudobrukit i da je završena fazna transformacija anatasa u rutil,
kao i da je dalje povišenje temperature utiče na prelaz
monokliničnog u rombični pseudobrukit. Uzorci sinterovani na 850 C
imali su malu veličinu zrna sa homogenom strukturom, dok je dalje
povišenje temperature uticalo na formiranje pseudobrukita sa većim
zrnima štapićastog oblika. Strujno-naponska analiza pokazala je da
uzorak 60%α-Fe2O3/40%TiO2 sinterovan na 850 C ima mogućnost za
primenu u fotoelektrohemijskim ćelijama...

▼ Dinitrosyl
iron complexes (DNICs), as well as S-nitrosothiols (RSNOs), form endogenously to provide a stable means of storage and transport for the highly reactive signaling molecule, nitric
oxide. Through the development of biomimetic complexes, the fundamental chemistry of such DNICs is established within a range of ligand sets as anionic and neutral donors that stabilize the dinitrosyl
iron unit, DNIU, in oxidized {Fe(NO)₂}⁹ and reduced {Fe(NO)₂}¹⁰ (Enemark-Feltham notation) redox levels. This amorphous electronic characteristic is readily accommodated by amino acid residues, cysteinyl S- and histidine N-donors, and their surrogates, as ligands to
iron. My research targets a greater understanding of DNIC reactivity with components of cellular environments, the possible connections between the electronically similar d⁹ , Cu(II) and d¹⁰, Cu(I), redox couple, the DNIC/Copper/RSNO connections, structural studies of aggregates of DNICs with metallodithiolates, as well as design strategies for NO-release therapeutic development of DNICs.
A stable, reduced, {Fe(NO)₂}¹⁰ DNIC containing a bipyridyl ligand, [(neo)Fe(NO)₂] (neo = 2,9-dimethyl-1,10-phenanthroline) was used to explore redox switches and N₂ ligand exchange between copper and the Fe(NO)₂. Both Cu^I and Cu^II sources were found to promote neo ligand transfer from the DNIU with concomitant NO release. With Cu^II, redox processes were also involved, as evidenced by the formation of a mixture of oxidized {Fe(NO)₂}⁹ DNICs, in addition to both Cu^I- and Cu^II-neo complexes. Copper is known to catalyze the release of NO from RSNOs, and our discoveries found here are the first biomimetic investigation of copper’s reactivity with DNICs.
Reaction of an RSNO with reduced, {Fe(NO)₂}¹⁰ DNICs, [(L)₂Fe(NO)₂] (L = CO or neo), results in NO release and the formation of a unique (-S)(SR)₂[Fe(NO)₂]₄ cluster, containing an interstitial sulfide. Such a cluster can be visualized as a plausible intermediate in the known conversion of DNICs to FeS clusters. The NO released showed complete scrambling with ¹⁵N-labeled RSNO.
Although DNICs are promising NO-delivery candidates, the lack of biocompatible examples has hindered their development into useful therapeutics. We reported the first DNICs with pendant thiosugars, isolated in both monomeric and dimeric form. Cytotoxicity towards endothelial cells was low and steady NO release over several hours was observed in aqueous media.
