▼ Cellular viability represents whether a cell is performing normal functions, relating to intracellular energy synthesis. Accurately quantifying the cellular viability would facilitate novel studies on how pathological environments affect the functioning of cells in various diseases. Nevertheless, technologies for monitoring the cellular viability in live tissue models are currently lacking. This study aims at testing a recently developed technology, which integrates dynamic light scattering and optical coherence tomography (called DLS-OCT), to image the cellular viability with single-cell resolution. DLS analyzes fluctuations in light scattered by particles to measure diffusion or flow of the particles, and OCT uses coherence gating to collect light only scattered from a small volume for high-resolution structural imaging. Integrating the two technologies, DLS-OCT constructs high-resolution diffusion coefficient and flow velocity 3D maps. It is known that the motion of intracellular organelles, often called intracellular motility, resembles a random walk in the confined cytoplasm space, thus it can be quantified by the diffusion coefficient. Since the intracellular motility is correlated with the cell’s metabolism level, the diffusion coefficient map of DLS-OCT is expected to enable us to image the cellular viability. Here, the DLS-OCT imaging of cellular viability was validated by characterizing responses of the measured intracellular motility to the environmental conditions such as the temperature and pH, in animal retinal explant samples. First, we characterized our new OCT system and optimized scanning sequences and processing procedures for DLS-OCT data, to match the dynamic range of our DLS-OCT measurement with the typical range of intracellular motility. Both numerical simulation and phantom experiments were performed for optimization. Second, methods required for animal retinal explant experiments were established, and DLS-OCT data from retinal tissue while manipulating the cellular viability were acquired and analyzed, to test the technical hypothesis that DLS-OCT-measured intracellular motility of neurons significantly diminishes when the cellular viability levels are out of the physiological ranges. Similar operations were performed to tissue spheroids with additional morphological measurements. As a result, we measured individual cells’ healthiness for tempered conditions, which will enlighten studying cells’ healthiness during disease progress or therapeutic treatment in stroke, epilepsy, and Alzheimer’s disease among others.

▼ Dynamic Light Scattering (DLS) is a commonly used analytical technique for measuring the size distribution of particles in solution. DLS is an attractive technique because it is non-invasive (a low power laser is used so as not to damage the samples), requires very little sample preparation, and can extract information from small volume samples with relatively low particle concentrations. For these reasons, DLS has become a widely used analytical technique in many industries. For example, in the development of new biopharmaceuticals, one of the major limitations is the large number of tests that must be performed on limited amounts of sample. DLS allows researchers to extract size distribution information from as little as 2 μL of sample, saving the rest of the sample for other required tests. Although the size range of particles that can be analyzed via DLS is large (ranging from .03 nm to 10 μm), careful attention must be paid to the concentration of particles larger than 500 nm. If the concentration of larger particles is too high, it can prevent accurate measurement of the smaller sized particles. However, many applications produce samples containing particles above and below 500 nm (i.e. proteins and protein aggregates). The goal of this thesis was to develop an acoustic-based separation technique that could establish a tunable cutoff diameter and remove all particles larger than the cutoff diameter. The concept of acoustic-based separation was initially demonstrated in a laboratory setting with polystyrene beads. First, mixed samples were analyzed by DLS. The samples were then passed through our acoustic filter, and the smaller fraction was again analyzed by DLS and compared to both the initial measurements and samples of known concentrations. Results showed that our acoustic filter drastically improved the quality of the DLS measurements. Finally, we replaced the expensive lab equipment with custom electronics and constructed a prototype for acoustic nanoparticle separation.

▼ Uranyl peroxide cage clusters include a large family of more than 50 published clusters of a variety of sizes, which can incorporate various ligands including pyrophosphate and oxalate. Previous studies have reported that uranyl clusters can be used as a method to separate uranium from a solid matrix, with potential applications in reprocessing of irradiated nuclear fuel. Because of the potential applications of these novel structures in an advanced nuclear fuel cycle and their likely presence in areas of contamination, it is important to understand their behavior in both solid state and aqueous systems, including complex environments where other ions are present. In this thesis, I examine the aqueous behavior of U24Pp12, as well as aqueous cluster systems with added mono-, di-, and trivalent cations. The resulting solutions were analyzed using dynamic light scattering and ultra-small angle X-ray scattering to evaluate the species in solution. Precipitates of these systems were analyzed using powder X-ray diffraction, X-ray fluorescence spectrometry, and Raman spectroscopy. The results of these analyses demonstrate the importance of cation size, charge, and concentration of added cations on the aqueous behavior of uranium macroions. Specifically, aggregates of various sizes and shapes form rapidly upon addition of cations, and in some cases these aggregates appear to precipitate into an X-ray amorphous material that still contains U24Pp12 clusters. In addition, I probe aggregation of U24Pp12 and U60, another uranyl peroxide cage cluster, in mixed solvent water-alcohol systems. The aggregation of uranyl clusters in water-alcohol systems is a result of hydrogen bonding with polar organic molecules and the reduction of the dielectric constant of the system. Studies of aggregation of uranyl clusters also allow for comparison between the newer uranyl polyoxometalate family and century-old transition metal polyoxometalates. To complement the solution studies of uranyl cage clusters, solid state analyses of U24Pp12 are presented, including single crystal X-ray diffraction and preliminary single crystal neutron diffraction. Solid state analyses are used to probe the complicated bonding environments between U24Pp12 and crystallized counterions, giving further insight into the importance of cluster protonation and counterions in uranyl cluster systems. The combination of solid state and solution techniques provides information about the complicated nature of uranyl peroxide nanoclusters, and insight towards future applications of clusters in the advanced nuclear fuel cycle and the environment.

▼ It is established that the cleansing properties and irritation potential of surfactants can be managed with the addition of other surfactants or polymers. However, the mechanism of the surfactant-induced irritation is not fully understood. In 2003, the Blankschtein group used 14C-radiolabelling assay and dynamic light scattering (DLS) to study the penetration of sodium dodecyl sulfate (SDS) and a system of SDS with polyethylene glycol (PEG) through porcine skin. They concluded that the micelles and monomers contributed to skin irritation and the irritation potential of a surfactant was dependent on the size of the assembly body (this is referred to as the “Blankschtein Hypothesis” within this body of work). Herein, we use combined small-angle neutron scattering (SANS), DLS, and proton nuclear magnetic resonance (1H-NMR) spectroscopy to investigate the shape, size, and solution dynamics of the surfactant systems to further elaborate the “Blankschtein Hypothesis”. The results revealed that shape and inter-micellar interactions, in addition to size, serve as important factors in determining surfactant skin penetration.The validity of the Blankschtein Hypothesis was furthered explored by adding a clinical component to the study. Part of Nicole McCardy’s MS thesis work was to determine if pre-clinical assays, including 14C-radiolabeled skin penetration assay and DLS, could be used to predict the clinical results observed with human subjects. A model was built to predict the harshness of mixed surfactant and surfactant-polymer composition on human skin, as measured by corneometry and visual dryness scores in a five-day forearm controlled application test (FCAT). A similar method was applied to another set of formulations, simplified to contain only one anionic surfactant. All of the surfactants in this set were structurally similar, differing only slightly in chain lengths and functional groups. The pre-clinical assays in this study were correlated with clinical results, as measured by corneometry, visual redness scores, visual dryness scores, and transepidermal water loss (TEWL) in a 1-day Mini-Immersion study. Although several attempts were made, the results did not allow a statistically significant model to be built. It is speculated that the catalog of structurally similar surfactants caused the results for various assays to be too narrow, precluding the development of a meaningful model. At the current status, the results from the mini-immersion study neither contradicts nor supports the Blankschtein Hypothesis. Advisors/Committee Members: Kumari, Harshita (Committee Chair).

▼ The light shutter, one of the key elements of LC displays, is the device capable of controlling the amount of light passing through. Generally, the light shutter can be achieved by reflection, absorption, and scattering of light, and the applications have been extensively demonstrated. In this research, we attempt to fabricate a liquid crystal light shutter based on the scattering of light. Nowadays, there have been several ways to realize the scattering-mode liquid crystal light shutter, such as cholesteric liquid crystal (CLC), polymer-dispersed liquid crystal (PDLC), polymer-network liquid crystal (PNLC), polymer-stabilized cholesteric texture (PSCT), and the dynamic scattering mode (DSM). The potential application of such liquid crystal light shutter is the smart window, and privacy protection can be therefore achieved by the switch between the transparent and scattering state. The further application like patterned scattering area is expected to be achieved by using patterned electrodes or pixel electrodes. However, the process of patterned/pixeled electrodes is more complex than the one of common ITO-coated glass. To solve the problem, we attempt to realize the patterned scattering device by the property of DSM that the driving voltage is dependent on the concentration of ions. In this thesis, we employ the method of optically induced ion production and a mask to create spatial distribution of ions. Thus, the pattern, somewhere is optically transparent and somewhere is blurred, can be produced under an electric field. However, we discover that ions gradually diffuse over the liquid crystal cell, and it makes the device doesnât work. Therefore, the discussion on suppressing ion diffusion by encapsulation is also reported. In sum we are able to achieve different scattering patterns under different voltages, which is similar to the function of blinds.

Hemija i hemijska tehnologija - hemija i inzenjerstvo polimera / Chemistry and chemical engineering Polymer Chemistry and Polymer Engineering

Predmet istraživanja ove doktorske disertacije bila su dva tipa derivata skroba: anjonski i katjonski skrob. Za sintezu anjonskog skroba (karboksimetil-skrob) korišćena je monohlorsirćetna kiselina (ili njena natrijumova so), a za sintezu katjonskog skroba korišćen je 3-hlor-2-hidroksipropil-trimetilamonijum hlorid. U prvom delu rada ispitivan je uticaj reakcionih uslova i količine reagenasa na stepen supstitucije i granični viskozitetni broj karboksimetil-skroba. Na osnovu dobijenih rezultata određeni su optimalni uslovi pod kojima je sintetisano šest uzoraka karboksimetil-skroba – tri uzorka su pripremljena od skroba iz krompira, a tri od skroba iz kukuruza. Stepen supstitucije sintetisanih uzoraka je iznosio od 0.40 do 1.10. Uzorcima karboksimetil-skroba ispitivana su svojstva u razblaženim rastvorima upotrebom viskozimetrije, statičkog i dinamičkog rasipanja svetlosti. Kao rastvarač korišćeni su voda i rastvori natrijum hlorida u vodi. Za svaki uzorak određene su vrednosti molarne mase po masenoj zastupljenosti, MW, poluprečnika rotacije, Rg, hidrodinamičkog poluprečnika, Rh, i graničnog viskozitetnog broja, [η]. Utvrđeno je da u rastvorima soli poreklo skroba i stepen supstitucije (u ispitivanom opsegu) ne utiču na oblik i unutrašnju strukturu makromolekula. Svojstva u razblaženim rastvorima natrijum-hlorida zavise samo od jonske jačine rastvarača. Ispitivanje termičke stabilnosti sintetisanih uzoraka karboksimetil-skroba termogravimetrijskom analizom pokazalo je da porast temperature ima specifičan uticaj na osobine karboksimetil-skroba zavisno da li se on nalazi u kiselom obliku ili u obliku soli. Temperature na kojima dolazi do gubitka 5 i 50 mas.% su nezavisne od stepena supstitucije kod uzoraka karboksimetil-skroba u obliku soli, dok kod uzoraka karboksimetil-skroba u kiselom obliku postoji linearna zavisnost ovih temperatura od stepena supstitucije. Uzorcima su određene i energije aktivacije termičke degradacije i pokazalo se da je energija aktivacije termičke degradacije uzoraka karboksimetil-skroba u obliku soli niža, a energija aktivacije termičke degradacije uzoraka karboksimetil-skroba u kiselom obliku viša od energije aktivacije termičke degradacije nemodifikovanog skroba. Katjonski derivat je pripremljen modifikacijom skroba iz kukuruza. Sintetisan je jedan uzorak katjonskog skroba od koga su kontrolisanom ultrazvučnom degradacijom pripremljena još četiri uzorka. Vrednosti molarne mase po masenoj zastupljenosti, MW, poluprečnika rotacije, Rg, hidrodinamičkog poluprečnika, Rh, i raspodele molarnih masa uzoraka, su određene upotrebom gel-propusne hromatografije, statičkog i dinamičkog rasipanja svetlosti. Utvrđeno je da se sa povećanjem vremena ultrazvučne degradacije smanjuje molarna masa uzoraka uz istovremeno suženje raspodele molarnih masa. Ultrazvučnom degradacijom dobijeni su makromolekuli čiji oblik i unutrašnja struktura nisu međusobno slični. Na…

Géis são materiais que possuem aplicações em várias áreas, tais quais, na indústria de tintas, alimentos e farmacêutica. Os métodos empregados para obtenção dos géis podem ser físicos (interações físicas) e/ou químicos (baseado em interações covalentes), tal processo, é denominado gelificação. Neste trabalho, o processo de gelificação de quitosana/glutaraldeído foi monitorado utilizando reometria e espalhamento da luz (DLS). As funções de correlação de intensidade (ICF) foram obtidas através de DLS e a equação de Kohrausch-William-Watts (KWW) foi ajustada com os dados experimentais. Os parâmetros da equação KWW, β, Γ e C foram avaliados. Estes métodos foram eficazes na clarificação do processo que compreende a transição sol-gel, com o surgimento da não-ergodicidade, e na determinação da faixa de gelificação, observada em torno de 10-20 minutos. A dependência da viscosidade aparente em função do tempo foi utilizada para comprovar o tempo de gelificação observado no DLS.

Gels consist of soft materials with vast use in several activities, such as in pharmaceutical industry, food science, and coatings/textile applications. In order to obtain these materials, the process of gelification, that can be physical (based on physical interactions) and/or chemical (based on covalent crosslinking), has to be carried out. In this work we used dynamic light scattering (DLS) and rheometry to monitor the covalent gelification of chitosan solutions by glutaraldehyde. Intensity correlation function (ICF) data was obtained from DLS and the exponential stretched Kohrausch-William-Watts function (KWW) was fitted to them. The parameters of the KWW equation, β, Γ and C were evaluated. These methods were effective in clarifying the process of sol-gel transition, with the emergence of non-ergodicity, and determining the range of gelation observed in about 10-20 minutes. The dependence between apparent viscosity on reaction time was used to support the discussion proposed.

▼ In this dissertation, we study the role of microstructure and microdynamics in determining the functional properties of soft matter using rheology, dynamic light scattering (DLS), and particle-tracking video microscopy. This role is considered in two systems: aqueous solutions of chitosan and active Janus microspheres. The microdyanmical characterization of complex solutions is of broad scientific interest as understanding solution microstructure enables the prediction and manipulation of macroscopic properties. For chitosan, solution rheology is explored to probe the existence of an apparent yield stress. The possibility of shear-banded flow is investigated using a rheo-optical setup, and the quiescent microstructure of concentrated solutions is characterized using DLS. For active Janus microspheres, the microdynamics are characterized using DLS as a novel investigative technique. The macroscopic rheology of chitosan solutions features shear thinning at low shear rates consistent with the existence of an apparent yield stress. At shear rates above yielding, a constant viscosity plateau is observed with concentration-dependent scaling consistent with existing models of entangled and associating polymers below the gel point. The concentration-dependent scaling of the apparent yield stress, σ0(c) ~ c2.8±0.2 in the concentration range c = 7.50-65.0 mg/mL, is consistent with a solution microstructure of fractal clusters of fractal dimension df = 1.6±0.2. The addition of urea, a hydrogen bond and hydrophobic interaction disrupter, did not change the reported concentration-dependent scaling of the apparent yield stress or the plateau viscosity but did weaken the apparent yield stress magnitude by ~30% on average. The microdynamics of a concentrated chitosan solution and a weak chitosan gel were characterized by DLS. The extracted slow microdynamics are consistent with the presence of a ¬¬¬structured network or glassy fluid. To evaluate the possibility of shear banded flow of chitosan solutions in the shear rate range of the apparent yield stress, a rheo-optical instrument was used to measure the velocity profile in the gap between parallel plates. Silicone oil was applied around the gap to prevent rapid sample evaporation but resulted in image distortion as well as new secondary flows. To validate our modified experimental conditions, we carefully evaluate lower stress and shear rate limits using standard solutions. We find that in the experimentally valid shear rate range of γ ̇ = 0.01-0.056 1/s chitosan solutions do not exhibit shear banding. The shear rate range of characterization, although significantly lower than most literature measurements, does not completely rule out the possibility of shear banding in self-associating chitosan solutions. The microdynamics of active colloids were characterized using DLS as a novel investigative tool. In the presence of hydrogen peroxide, Janus microspheres of platinum and polystyrene undergo active motion by means of self-diffusiophoresis.

▼ The increasing availability of micellar casein obtained by membrane separation creates a need to better understand the effect of processing conditions, on the stability and properties of this ingredient. This work focused on studying the heat-induced interactions in micellar casein concentrates, and in micellar casein (MCN)-soy protein (SP) blends. These changes were investigated using a range of physical measurements (zeta potential and particle size measurements, rheological analyses) and chemical analyses (compositional, differential solubility and Native-PAGE analyses). First, heat induced effects on the properties of micellar casein (MCN)-soy protein (SP) blends (1:1 ratio) were evaluated. Individual and mixed protein systems of 2.5% - 15% concentration were subjected to temperatures between 40[MASCULINE ORDINAL INDICATOR]C - 95[MASCULINE ORDINAL INDICATOR]C. Heat treatments at T[GREATER-THAN OR EQUAL TO]80[MASCULINE ORDINAL INDICATOR]C induced soy protein (glycinin) denaturation, which resulted in protein aggregation and network formation by disulfide bonding, when soy protein content >6.3%. There was no evidence of cross-linking between soy proteins and casein micelles, as disulfide bonding seemed to occur exclusively between soy protein molecules. In MCN-SP mixtures with soy protein content <6.3%, thermal denaturation of soy proteins induced local phase separation between the casein micelles and the soy protein molecules. This resulted in protein mixtures with low shear viscosity, Newtonian flow behavior and very good stability to sedimentation. In the second part, the effect of commercial sterilization (UHT - ultra high temperature - treatment and retorting) on micellar casein concentrates (MCC) of 5% 10% casein concentration was evaluated. Sterilization affected the stability, viscosity and flow behavior of MCCs, mainly due to loss in solubility of calcium phosphate at the micelle level. Retorting resulted in slight aggregation of casein micelles, while UHT caused the formation of visible aggregates. The UHT treated MCCs had higher viscosity than retorted MCCs, and displayed a solid-like behavior, indicative of structure formation. Drying of MCCs affected their sterilization behavior, as reconstituted micellar casein concentrates (R-MCCs) were more unstable to UHT sterilization than MCCs. The calcium concentration per gram of casein was identified as critical parameter for the heating stability of MCCs. This work provides critical information for developing commercial applications of micellar casein, as well as micellar casein-soy mixtures.

▼ Polymer nanocomposite (PNC) research is a burgeoning field of study in material science owing to the interesting material properties afforded to nanoscale interaction between polymer and nanoparticle. Despite the wealth of different applications being pursued for study, the fundamental parameters that control these emergent properties are not well understood. These knowledge gaps include what controls the interfacial polymer layer 1-5 nm away from the nanoparticle surface as well as what role nanoparticle characteristics play in affecting the macroscopic properties of PNCs. This dissertation combines different static and dynamic experimental techniques to probe both polymer- and nanoparticle-specific parameters with the goal of understanding how they control dynamics and local structure in PNCs. For the polymer perspective, a conceptually more accurate heterogeneous model analysis of the dielectric spectra of PNCs is shown to reveal two important features: that the interfacial polymer layer grows significantly with cooling and that the chains in the interface have less freedom of motion because of chain stretching. This analysis is further used to demonstrate that polymer chain rigidity increases the extent of the interfacial layer above a critical rigidity. The conformational state of polymers is further explored with dielectric spectroscopy where stretched or flattened chains are shown to have a reduced dielectric amplitude from the neat polymer. From the nanoparticle perspective, unique macroscopic properties are shown to be achievable with small, attractive 2 nm nanoparticles (NPs) that are on the order of a polymer segment size. These PNCs with 2 nm NPs differ from PNCs with conventionally sized NPs studied previously by having large changes in mechanical properties while simultaneously having small changes in viscoelastic properties at high temperatures. These effects are attributed to enhanced NP mobility, which is controlled by the temperature-sensitive polymer-NP desorption time. The diffusion of nanoparticles in a polymer melt is studied systematically with polymer molecular weight. The diffusion results are explained with a simple model which argues that NPs transition from a NP-dominant core-shell mechanism to a polymer-dominant vehicle mechanism as the chain length increases, a transition which depends on NP size and the polymer-NP desorption time.

▼ An artificial platelet nanotechnology with threshold-switchable procoagulant functionality is devised, employing one of the human body’s intrinsic hemostatic agents, inorganic polyphosphate (polyP). Inspired by the manner in which the anionic polyelectrolyte is stored in human platelets and how it exerts its hemostatic effects, polyP is nanoprecipitated in aqueous, polyvalent metal salt solutions. The particle formation is characterized by dynamic light scattering (DLS), and the particle morphology, structure, and elemental composition is determined by transmission electron microscopy (TEM) and energy-dispersive X-Ray spectroscopy (EDS). The ability for the polyP nanoparticles (NPs) to initiate blood coagulation in human plasma is accomplished by a standard turbidometric experiment assaying for contact pathway activation, validating that polyP NPs manifest robust procoagulant ability compared against the molecularly dissolved polymers of the same molecular weight. PolyP granules are stored in lipid bilayer shells approximately 250 nm across. These core-shell granular nanoparticles are referred to as dense granules in human platelets because of the presence of high molecular weight elements and their appearance under an electron microscope. A route to achieve a similar nanostructure is realized by brief ultrasonication of granular polyP NPs with sterically stabilized liposomes to give an Artificial Dense Granule (ADG). DLS was utilized to qualify colloidal stability and polyP encapsulation efficiency. High resolution imaging and two-dimensional spectroscopy are employed to verify the ADG core-shell structure and elemental distribution. A central design element of ADGs is to rapidly release the polyP cargo in the presence of high concentrations of phospholipase enzymes typically overexpressed in the blood stream adjacent to hemorrhagic bleeding sites. As a proof of concept, it is demonstrated that ADGs may initiate the contact pathway of blood coagulation in isolated protein assays and in human plasma only at above-threshold enzyme concentrations. In addition to its hemostatic functionality, polyP also serves as a generic molecular chaperone. Leveraging polyP’s role as a protein binder, polyP nanoprecipitation is further investigated for its ability to assist as a protein delivery vehicle using human factor VIII (FVIII) as a model protein. FVIII and polyP were co- nanoprecipitated in aqueous calcium and encapsulated in sterically stabilized liposomes. The ADG-FVIII NPs were subsequently assayed for their ability to clot FVIII-deficient plasma, a simplified model for Hemophilia A. However, further work is necessary to confirm the resulting particle’s morphology and the protein distribution. Although the groundwork has been created for a threshold-switchable procoagulant nanoparticle, additional ADG iterations must be created that are more structurally stable and more closely mimic actual human platelets. Further, these novel prototypes must be more rigorously tested in in vitro models… Advisors/Committee Members: Liu, Ying (advisor), Sharma, Vivek (committee member), Berry, Vikas (committee member), Du, Xiaoping (committee member), Perez-Salas, Ursula (committee member), Liu, Ying (chair).
