▼ The kinetics of heterogeneous nucleation, growth, and recrystallization (i.e., Ost-wald ripening) of environmentally abundant nanoparticles (i.e., ferrihydrite, barite, and lead phosphate) on substrates were quantified using in situ grazing incidence small angle X-ray scattering (GISAXS). To explore the mechanisms, the interactions among nanopar-ticles, substrates, and ions were investigated. Ferrihydrite nanoparticles can sequester various metal ions (i.e., Cu2+, Pb2+, Cr3+, Ni2+, Cd2+, Al3+, and Mn2+), and form impure ferrihydrite nanoparticles. The sequestration mechanisms (i.e., surface enrichment and structural incorporation) of these metal ions with ferrihydrite at acidic pH condition were identified, which were related to the metal ion hydrolysis. Also, these metal ions showed selective adsorption behaviors onto differ-ent substrates (i.e., quartz and corundum), which were controlled by the hydrolysis of these metal ions and the dielectric constants of the substrates. The electrostatic interac-tions between particles and substrates governed the heterogeneous nucleation, growth, and recrystallization (i.e., Ostwald ripening) processes of ferrihydrite. Barium sulfate (BaSO4) is a common scale-forming mineral in natural and engi-neered systems. Under [Ba2+]/[SO42-] = 1, little amount of BaSO4 formed on bare and –COOH coated glasses; Meanwhile, BaSO4 heterogeneous nucleation was significantly promoted on–SH and mixed –SH & COOH coatings. We also found that heterogeneous precipitation rate increased under [Ba2+]/[SO42-] > 1. These observations suggest that thermodynamic favorability for nucleation is governed by substrate-water interfacial en-ergy; while given favorable thermodynamics, rate is governed by ion attachment to sub-strates and incipient nuclei. Phosphate is added to Pb-contaminated soils to induce lead immobilization through lead phosphate precipitation. Here, heterogeneous lead phosphate nucleation on coatings was measured from mixed Pb(NO3)2 and Na2HPO4/NaH2PO4 solutions at pH 7 with varied ionic strengths (IS = 0.58, 4, and 11 mM). Raman spectroscopy identified the homogeneous precipitates in solution as hydroxylpyromorphite (Pb5(PO4)3OH). The smallest lead phosphate nuclei (4.5 ± 0.5 nm) were observed on –COOH coatings, which resulted from the highest level of lead and phosphate ion adsorption on –COOH coatings. The IS of the solution also affected the sizes of the heterogeneous precipitates on –COOH coating, with smaller nuclei (1.3 ± 0.4 nm) forming under higher IS (4 and 11 mM).

▼ Studies of nucleation in freezing nanoparticles usually assume that the embryo of the solid phase is completely wet by the liquid and forms in the core of the droplet. However, recent experiments and computer simulations have suggested that some nanoparticles start nucleating at the liquid-vapor interface of the drop in a pseudoheterogeneous process. The goal of the present work is to propose phenomenological models suitable for the study of surface nucleation in nanoparticle systems that can be used to understand the contributions of the various surface phenomena, such as surface and line tensions, to the nucleation barrier. The nucleation barrier for the freezing of a 276 atom gold cluster is calculated using Monte Carlo simulation techniques while previous simulation studies of a 456 atom gold cluster are extended in order to find the probability that the embryo forms in the surface or core of the nanoparticle. These calculations confirm that the crystal embryo forms at the liquid-vapor interface. Geometric studies measuring the liquid-solid and solid-vapor surface areas of the embryo suggest that it changes shape as it becomes larger and grows in towards the core of the droplet. Three phenomenological models that are based on the capillarity approximation and can account for surface nucleation are proposed. These models highlight the importance of accounting for the surface curvature contributions related to the Tolman length and the presence of the three phase contact line in calculating the nucleation free energy barrier. In some cases, the models are able to reproduce the qualitative properties of the free energy barriers obtain from simulation but numerical fits of the models generally result in estimates of the solid-liquid surface tension that are lower than the values expected on the basis of partial wetting in the bulk. Finally, a semi-phenomenological model approach to nucleation is proposed where the usual phenomenological expression for the free energy barrier is retained, but where the geometric prefactors are obtained from molecular simulation of the embryo. This method is applied to nucleation in the gold cluster and to the freezing of a bulk Lennard-Jones liquid.

In this thesis the influence of solvents on crystal nucleation is probed to progress understanding of crystal nucleation from solution. Induction times of two solutes in different solvents and at different thermodynamic driving forces were measured using a custom 20 mL multireactor system. To account for the wide distribution of induction times under identical conditions, around 2,000 induction times were collected, covering 25 combinations of solute, solvent and thermodynamic driving force. Both the thermodynamic driving force required to achieve median induction times of 2 hours, and the interfacial energies calculated using the Classical Nucleation Theory, were found to decrease in the order ethanol > isopropanol > toluene > ethyl acetate for fenoxycarb, and [n-propanol & toluene] > ethyl acetate > acetonitrile for tolbutamide. Thus both solutes nucleate more easily in ethyl acetate than in either toluene or the alcohols. Absolute values of interfacial energies ranged from 0.5 to 5 mJ/m2 in line with results of similar experiments in the literature. For fenoxycarb these correlated quite well with solvent-solute interaction enthalpies (with the exception of toluene) such that stronger binding of the solute by the solvent corresponded to more difficult nucleation. This trend has recently also been reported for salicylic acid and risperidone. In the case of tolbutamide the same relationship appeared to be complicated by a second mechanism, whereby tolbutamide assumes different solvent-dependent conformers in solution that hinder nucleation relative to the energy barrier of rotating to the conformer found in the crystal. While collecting induction times for fenoxycarb in isopropanol, a history of solution effect on the nucleation rate was discovered whereby nucleation becomes more difficult with increasing pretreatment temperature and time. Such an effect has been sporadically reported for the past 100 years, but its cause remains unsolved. In order to quantify this effect, the influence of solution pretreatment on the nucleation was measured by collecting 1,800 induction times spanning 17 combinations of pretreatment time and temperature. The influence of pretreatment time and temperature on the induction time was found to follow a first order rate reaction with an activation energy of over 260 kJ mol-1. On the basis of modelling it has previously been suggested for this system that the molecular packing in the crystal lattice is not the thermodynamically stable configuration at the level of simple dimers in solution, and that solute aggregation must exist in solution due to the low solvent-tosolute molecular ratio. It is thus hypothesized that the dissolution of crystalline material at first leaves molecular assemblies in solution that retain features of the crystalline structure, which facilitates subsequent nucleation. However, the longer the solution is kept at a temperature above the saturation temperature and the higher the temperature, the more these …

▼ Re-establishment of appropriate vegetation communities is an important aspect of successful forest reclamation as they contribute to various ecosystem functions. In my research I explore how different coversoil materials (salvaged forest floor (FFM) and peat material), their placement depths, and underlying subsoil materials influence the early colonizing vegetation on an upland boreal forest reclamation site. Further, I investigated what effects the selection of tree species and their planting densities have on vegetation community development. As salvaged FFM contains propagules common of upland forests, it provided much higher richness and cover than when peat material was used as a coversoil. While material placement depth had little impact on vegetation, the type of subsoil material did play a role when placed beneath the coversoils, particularly with high phosphorous availability resulting in increased plant cover and species richness. Selection of tree species had little effect on the vegetation within the timeframe measured as seedlings were likely too small. Planting density had an impact early on with reduced vegetation cover in high density plots where seeding growth was high (in FFM). In a second study, I explored whether FFM islands would act as a nucleus for dispersal of forest vegetation throughout reclaimed landscapes. Vegetation egress and seed rain from the islands into adjacent peat material were examined to assess the dispersal mechanisms contributing to the egress. By the fourth growing season, species associated with FFM comprised a higher proportion of the vegetation cover than species associated with the receiving peat material up to 20m away from the island border. Although overall cover was low compared to in FFM areas, herbaceous, graminoid, and shrub species associated with the FFM were all present in the peat. Wind dispersed species were able to disperse further into the surrounding peat material than species which utilized other dispersal methods. Despite seeds successfully dispersing from FFM areas, poor seed bed conditions in the peat limited seed retention and germination. However, dispersal into peat with vegetative reproductive structures appears promising as a result of the material’s high nitrate concentrations and water holding capacity.

▼ The main objective of this work was to assess the effect of 10% (w/v) polyvinylpyrrolidone (PVP) on the pattern of intracellular ice formation (IIF) in human adipose tissue derived adult stem cells (ASCs) in the absence of serum and other cryoprotective agents (CPAs). Passage 1 (P1) ASCs were cultured, washed and suspended in either 1x PBS (Phosphate Buffered Saline) or 10% w/v solution of PVP in 1x PBS. The freezing experiments were carried out using a fluorescence microscope equipped with a Linkam™ cooling stage using two different temperature/time cooling protocols. Both the cooling protocols had a common cooling ramp: cells were cooled from 20 ˚C to –8 ˚C at 20 ˚C/min and then further cooled to –13 ˚C at 1 ˚C/min (during which the extra-cellular medium froze very rapidly and was accompanied by the formation of intracellular ice in ~96% of the cells, as noted by visible "flashing/darkening"). At this point we employed either, cooling protocol 1: the cells were cooled from –13 ˚C to – 40 ˚C at a pre-determined cooling rate of 1, 5, 10, 20 or 40 ˚C/min and then thawed back to 20 ˚C at 20 ˚C/min; or cooling protocol 2: the cells were re-warmed from –13 ˚C to –5 ˚C at 20 ˚C/min and then re-cooled at a pre-determined rate of 1, 5, 10, 20 or 40 ˚C/min to –40 ˚C. Almost all (>95%) of the ASCs frozen in 1x PBS and protocol 1 exhibited IIF whereas almost none (<5%) of the ASCs frozen in 1x PBS and protocol 2 exhibited IIF. The lack of IIF in cells cooled in 1x PBS and protocol 2 was due to the initial loss of cell viability (confirmed through an additional membrane dye exclusion study) that was associated with the formation of IIF in the common cooling ramp, described earlier. Similarly, almost all (>95%) of the ASCs frozen in 10% PVP in PBS and protocol 1 exhibited IIF where as ~0, ~40, ~47, ~67 and ~100% of the ASCs frozen in 10% PVP in PBS and protocol 2 exhibited IIF at a cooling rate of 1, 5, 10, 20 or 40 ˚C/min, respectively. The observed increase in the % of ASCs exhibiting IIF when frozen in 10% PVP and protocol 2, is presumably due to PVP mitigating the damaging effects of IIF during the common cooling ramp.

▼ The role of heterogeneity in two long-range systems is explored with a focus on the interplay of this heterogeneity with the component system interactions. The first will be the heterogeneous Ising model with long-range interactions. Earthquake fault systems under long-range stress transfer with varying types of heterogeneity will be the second system of interest. First I will review the use of the intervention method to determine the time and place of nucleation and extend its use as an indicator for spinodal nucleation. The heterogeneous Ising model with fixed magnetic sites will then be reformulated as a dilute random field Ising model. This reformulation will allow for the application of spinodal nucleation theory to the heterogeneous Ising model by correcting the spinodal field and the critical exponent sigma describing the critical behavior of clusters in spinodal nucleation theory. The applicability of this correction is shown by simulations that determine the cluster scaling of the nucleating droplets near the spinodal. Having obtained a reasonable definition of the saddle point object describing the nucleation droplet, the density profile of the nucleating droplet is measured and deviations from homogeneous spinodal nucleation are found due to the excess amount of sparseness in the nucleating droplet due to the heterogeneity. Earthquake fault systems are then introduced and a connection is shown of two earthquake models. Heterogeneity is introduced in the form of asperities with the intent of modeling the effect of hard rocks on earthquake statistics. The asperities are observed to be a crucial element in explaining the behavior of aftershocks resulting in Omori's law. A second form of heterogeneity is introduced by coupling the Olami-Feder-Christensen model to an invasion percolation model for the purpose of modeling an earthquake fault system undergoing hydraulic fracturing. The ergodicty and event size statistics are explored in this extended model. The robustness of the event size statistics results are explored by allowing for the dissipation parameter in the Olami-Feder-Christensen model to vary.

▼ This work investigates the mechanism for the heterogeneous nucleation of active pharmaceutical ingredients (APIs) in the presence of different excipient heterosurfaces. By elucidating this mechanism for a range of API molecules, the appropriate crystallisation conditions and heterosurfaces can be selected in silico for individual APIs to then generate API crystals of the desired size and morphology via controlled heterogeneous crystallisation processes, thus facilitating control over the API dissolution process. The crystallisation of seven APIs (acetaminophen (AAP), carbamazepine (CBMZ), caffeine (CAF), phenylbutazone (PBZ), risperidone (RIS), clozapine base (CPB) and fenofibrate (FF)) was studied in the absence and presence of the excipients α/β-lactose (α/β-lac), β-D-mannitol (β-D-man), dextran (DEX), chitosan (CHT), carboxymethyl cellulose (CMC) and microcrystalline cellulose (MCC), each of which acted as a heterosurface. Two of the APIs, namely AAP and CBMZ, possess hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA) functionalities whereas the other five only possess HBA functionality. The crystallisation experiments for all seven APIs were carried out within or at the limit of their respective metastable zones at supersaturation ratios in the range of 1.08 to 1.50. A novel methanol solvate of CPB was also discovered during these crystallisation experiments. API crystallisations in the presence of a heterosurface were accompanied by a more pronounced acceleration of the crystallisation for those APIs possessing only HBA functionality relative to the acceleration observed for the APIs possessing HBA and HBD functionalities. The smallest heterosurface acceleration of crystallisation was observed for CBMZ at 1.4 times and the largest was observed for FF at 16 times. For all the APIs studied, the interfacial energy was similar for crystallisations carried out in the presence and absence of the heterosurface; by contrast, the pre-exponential factor was generally larger for crystallisations carried out in the presence of the heterosurface than in its absence. Density Functional Theory (DFT) and Molecular Density calculations complemented the above experimental study. Thereafter, a model of heterogeneous crystallisation was developed wherein two factors were identified. The first of these was the complementarity of hydrogen bonding between the heterosurface and the APIs. Hence the crystallisation of APIs without HBD functionality was accelerated more strongly than for those with HBA and HBD functionality because the heterosurface provided the HBD functionality lacking in these APIs which allowed them to attach or adsorb to the heterosurface and thus act as nucleation points for the API’s crystallisation. The second factor identified was that the hydrogen bonding lifetime of the individual API molecules or small API clusters attached to a heterosurface is much longer (up to 1000 times) than (i) the lifetime of API-API interactions in the solution phase, or (ii) the time required for an API molecule to add to a… Advisors/Committee Members: Hodnett, Benjamin K., Hudson, Sarah P., Davern, Peter.

▼ Failure in structural materials occurs initially by localization of deformation, and subsequently through a process of nucleation, growth and coalescence of voids. Predicting material failure requires a careful investigation of the different stages of damage evolution at the multiple scales. The main objective of this thesis is to explore the evolution of damage and to correlate this with the deformation of the material at the continuum and microstructural levels. This is accomplished through macroscopic measurements of strain evolution using digital image correlation and microscale measurements of strain and damage using optical and scanning electron microscopy. Three materials with different microstructure were examined. In oxygen-free, high-conductivity copper, a high-purity material without appreciable second phase particles, strain levels in the order of three were observed in the material without any trace of damage. Failure was observed to be triggered by plastic instability in the form of shear bands and the emergence of a prismatic cavity that grows in a self-similar fashion by an alternating slip mechanism. In Al 6061-T6, a material with a dispersion of second phase particles at a volume fraction of about 0.01, nucleation of damage does not appear until plastic strain levels of 0.5 to 1.0. Once damage in the form of particle fracture or decohesion at the interface initiates, subsequent failure follows by the void nucleation, growth and coalescence; but, dominated by the fluctuations in the distribution of second phase particles, final separation occurs in a highly localized layer of material on the order of the grain size, corresponding to a small increase in the overall strain. In nodular cast iron, a material with an initial porosity of about 0.10, growth of voids was observed initially, but this was terminated by a transition of the deformation into a localized region. Phenomenological models based on strain-to-failure and micromechanical models based on a mechanistic description of the microscale deformation are evaluated in light of the above examination of failure in these three classes of materials.

▼ Cross-β fibrous protein polymers or “amyloids” are associated with a variety of human and animal diseases, including Alzheimer’s disease (AD), Parkinson’s disease (PD), and Huntington’s disease (HD) and are suspected to possess transmissible (prion) properties. However, the molecular mechanisms of amyloid formation and propagation are difficult to investigate in vivo due to complexity of the human organism. While evolutionarily distant from humans, yeast cells carry transmissible amyloids (yeast prions) that can be detected phenotypically. The objectives of the work presented in this dissertation were to understand the molecular mechanisms of initial prion nucleation and propagation by mammalian proteins in yeast. Our model employed chimeric constructs, containing the mammalian amyloidogenic proteins (or domains) fused to various fragments of the yeast prion protein Sup35. Phenotypic and biochemical detection assays, previously developed for the Sup35 prion, enabled us to detect prion nucleation and propagation by mammalian proteins. We have demonstrated that several non-Q/N rich, mammalian amyloidogenic proteins, nucleated a prion in yeast in the absence of pre-existing prions. Sequence alterations antagonizing or enhancing amyloidogenicity of human Aβ (associated with AD) and mouse PrP (associated with prion diseases) respectively antagonized or enhanced nucleation of a yeast prion by these proteins. Mutational dissection of Aβ identified sequences and chemicals that influence initial amyloid nucleation. We have also shown that Aβ and microtubule-associated binding protein tau that is also associated with AD, could propagate a prion state on their own or after transfection with in vitro generated amyloid seeds, in yeast. Aβ- and tau-based chimeric constructs formed distinct variants (“strains”) in the yeast cell. Our data show that prion properties of mammalian proteins detected in the yeast assays correspond with those found in mammals or in vitro, thus making yeast a powerful model for deciphering molecular foundations of amyloid/prion diseases.

▼ Numerical simulations of nanoparticle nucleation in turbulent shear flows are performed. We consider the homogeneous nucleation of dibutyl-phthalate (DBP) nanoparticles via direct numerical simulation (DNS) and large-eddy simulation (LES). The flows consist of a high-temperature, DBP-laden stream issuing into a low-temperature, faster or slower moving, DBP-free environment. As the flows cool, via molecular and large- scale convective mixing, the DBP vapor becomes highly supersaturated and particles are formed by nucleation. This particle formation takes place in the absence of condensation or coagulation. Classical nucleation theory is used to model particle nucleation and the Navier-Stokes equations are coupled with the scalar transport equations to provide the fluid, thermal, and chemical fields. The effects of large-scale mixing and vapor concentration on homogeneous nucleation rates are investigated via DNS in three-dimensional planar jets. The simulation results provide a demonstration of how nucleation takes place in narrow regions where molecular mixing of the two streams occurs. When maximum nucleation rates occur in conditions where the nucleation rates are sensitive to ambient conditions, islands of nucleation form. There are two possible nucleation events: initial shear layer nucleation, and later nucleation in coherent structures or eddies generated by the velocity difference between the jet and the co-flow. A scatter plot diagram of observed dilution paths in temperature versus condensable vapor concentration space where nucleation rates are superimposed is shown to be a convenient tool for analyzing nucleation events. Convection by large-scale eddies gradually spreads the range of mixing paths in this space towards higher nucleation rates. The results also show that boundary conditions, including inlet concentration and velocity ratio, have both qualitative and quantitative effects on particle nucleation. The effects of Lewis number on the homogeneous nucleation of DBP particles are also studied via DNS. Simulations at two Lewis numbers are performed to investigate the effects of molecular mixing on nucleation. These simulations are also carried out at two co-flow velocities to assess the effects of large-scale mixing. The results show that the Lewis number as well the level of large-scale mixing inherent in the flow have substantial effects on particle nucleation. The effects of the subgrid-scale (SGS) scalar interactions on nanoparticle nucleation are investigated via a priori analysis of DNS data. To assess the effect of SGS scalar interactions on DBP particle nucleation, the temperature and mass-fractions are filtered and the resulting quantities are used to compute the nucleating particle field. Two filter widths are used to obtain varying levels of SGS interactions. Particle size distributions are computed to examine the particle fields produced. This work shows that the SGS interactions' effect on nucleation has two distinct trends. In the proximal region of the flow, the unresolved…

▼ The potential for cavitation within reverse osmosis (RO) membranes was investigated by studying the effects of feed water degassing on RO desalination. Initial experiments, conducted using a laboratory-scale RO desalinator, and a range of NaCl feed solutions, showed a permeate flux increase of 3-5%, on average, upon feed solution degassing. These positive results led to the design and construction, with commercial support, of an industrial pilot-scale RO desalination system. Industrially prepared seawater feed was used, and operating conditions were chosen to reproduce, as closely as possible, those of industrial seawater RO installations. Upon pressure release by restricted flow, from 10-60bar to ambient pressure, cavitation was always observed when dissolved gases were present, but never with a degassed feed. Several RO membranes were found to be slightly hydrophobic, some with considerable surface heterogeneity, which supported the view that cavitation may occur within RO membranes. However, no permeate flux enhancement was observed with the pilot system, at degassing level of about 99%, for feed pressures in the range 38-55bar. In a study of osmotic distillation, it was found that the water flux, from pure water to NaCl solutions at various concentrations, correlated almost perfectly with the variation in solution vapour pressure with salt concentration. This process may be useful for the direct experimental measurement of osmotic pressures, and the determination of partial molar volumes of water in aqueous solutions. Simple asymmetric glass filter membranes were fabricated by fusing successive layers of different sized Ballotini beads. The filters were found to have predictable size-exclusion properties and good back-flushing tolerance. The simple fabrication process required only cheap, common resources. The filters proved capable of filtering a highly fouling suspension of organic waste in water, and recovered their initial flow rate upon back-flushing. Several studies were also conducted into some of the physical properties of water. High degassing levels were achieved by a simple boiling method. Degassed water was found to resist freezing, and supercool much more than atmospherically equilibrated water. The oxidation-reduction potential of water did not vary significantly upon degassing. The potential for feed water degassing for improved electrodialysis desalination was also investigated.

▼ Clathrate hydrates are a crystalline phase of water in which the hydrogen bond network forms polyhedral cages that can trap nonhydrogen bonding molecules such as methane and carbon dioxide. Methane clathrate hydrates occur naturally on the ocean floor and are so abundant that it is estimated they contain more energy than the rest of the world’s hydrocarbon reserves combined. As a result, methods to promote and inhibit the formation of clathrates are highly sought after. However, a detailed understanding of the microscopic mechanism of clathrate nucleation remains elusive. Experimental techniques are unable to resolve the structure of clathrate nuclei. Simulations provide an alternative, but nucleation is a stochastic event and the computational cost to observe nucleation events can be prohibitive. In this work we studied the mechanism of clathrate hydrate nucleation with molecular simulations using an efficient coarse-grained model mW that represents water as a single site that is encouraged to form “hydrogen-bonded” configurations without the use of hydrogen atoms. The coarse-grained model allows the observation of many more nucleation events than is possible with atomistic models. Using the coarse-grained water model and guest potentials, we studied the nucleation of clathrate hydrates at supercooled conditions. The nucleation mechanism we observed is a multistep mechanism with an amorphous intermediate that we call “the blob.” The first step in the nucleation is the densification of guest molecules in solution to form long-lived solvent-separated configurations. These persist in solution and give rise to the formation and dissolution of individual cages. Once “the blob” is large enough, it eventually forms persistent polyhedral cages. The critical nucleus is defined by the solvent-separated guest molecules and polyhedral water cages. The clathrate at this point is amorphous and lacks the symmetry of the crystalline clathrate, but is made of the same building blocks. We find that an amorphous clathrate seed is able to nucleate the formation of crystalline clathrates. We develop order parameters for the densification of guest molecules in solution, the identification of polyhedral cages, and the crystallinity of the clathrate phase. These order parameters will be useful for describing the reaction coordinate of clathrate nucleation at low driving force.

▼ Understanding and controlling the formation of ice and hydrates has important energy-related applications including ice mitigation, methane harvesting from hydrates, and desalination by freezing. This dissertation describes multiple studies to explore the role of surface chemistry and electric fields on the nucleation of ice and hydrates. The first part of this dissertation describes a study on saltwater ice formation. A majority of the available literature on ice mitigation concerns freshwater icing, unlike this study. This work quantifies the influence of surface chemistry and texture on saltwater ice formation. Two kinds of experiments are conducted as part of this effort. The first set of experiments quantifies the influence of surface chemistry on ice nucleation of various saltwater solutions. It is noted that a large number of individual experiments were conducted, which makes the present results statistically meaningful, unlike most previous studies. The second set of experiments studies the dynamics associated with impact of saltwater droplets on supercooled superhydrophobic surfaces. It is seen that the saltwater droplets retract more than freshwater droplets (after impact). The greater bounciness of saltwater droplets is a result of slower ice nucleation propagation kinetics. These experiments indicate that superhydrophobic surfaces will offer greater resistance to impact icing with saltwater than pure water and can remain useful at temperatures as low as -40 °C. The second part of the dissertation includes a detailed study of electrofreezing, i.e., the electrically induced nucleation of ice from supercooled water. This work studies ice nucleation in electrowetted water droplets, wherein there is no electric field inside the droplet resting on a dielectric layer. Instead, there is an interfacial electric field and charge buildup at the solid-liquid interface. Through carefully planned experiments, the influence of electric fields and electric currents on the freezing temperature elevation is quantified. The results facilitate an in-depth understanding of various mechanisms underlying electrofreezing. Firstly, interfacial electric fields alone can significantly elevate freezing temperatures by more than 15 °C in the absence of current flow. Secondly, electrofreezing-induced temperature elevation saturates at high electric field strengths. Thirdly, the polarity of the interfacial charge does not significantly influence electrofreezing. Finally, current flow can further elevate the nucleation temperature by providing additional triggers for nucleation events. Overall, both the electric field and the electric current influence electrofreezing; however, the physical mechanisms are very different. The third part of the dissertation studies a novel concept to induce rapid formation of hydrates. The long induction times (hours to days) associated with hydrate nucleation is a significant barrier to many hydrate-based applications. The present work shows that electro-nucleation can promote rapid hydrate… Advisors/Committee Members: Bahadur, Vaibhav (advisor), Bogard, David (committee member), Espinoza, David N (committee member), Ezekoye, Ofodike (committee member), Shi, Li (committee member).

▼ The dynamic motion of an earthquake begins abruptly, but is often initiated by a short interval of weak motion called the seismic nucleation phase (SNP). Ellsworth and Beroza [1995, 1996] concluded that the SNP was detectable in near-source records of 48 earthquakes with moment magnitude (Mw), ranging from 1.1 to 8.1. They found that the SNP accounted for approximately 0.5% of the total moment and 1/6 of the duration of the earthquake. Ji et al [2010] investigated the SNP of 19 earthquakes with Mw greater than 8.0 using teleseismic broadband data. This study concluded that roughly half of the earthquakes had detectable SNPs, inconsistent with the findings of Ellsworth and Beroza [1995]. Here 69 earthquakes of Mw 7.5-8.0 from 1994 to 2011 are further examined. The SNP is clearly detectable using teleseismic data in 32 events, with 35 events showing no nucleation phase, and 2 events had insufficient data to perform stacking, consistent with the previous analysis. Our study also reveals that the percentage of the SNP events is correlated with the focal mechanism and hypocenter depths. Strike-slip earthquakes are more likely to exhibit a clear SNP than normal or thrust earthquakes. Eleven of 14 strike-slip earthquakes (78.6%) have detectable NSPs. In contrast, only 16 of 40 (40%) thrust earthquakes have detectable SNPs. This percentage also became smaller for deep events (33% for events with hypocenter depth>250 km). To understand why certain thrust earthquakes have a visible SNP, we examined the sediment thickness, age, and angle of the subducting plate of all thrust earthquakes in the study. We found that thrust events with shallow (<50 km) hypocenters with thick seafloor sediments (>600 m) on the subducting plate tend to have clear SNPs. If the SNP can be better understood in the future, it may help seismologists better understand the rupture dynamics of large earthquakes. Potential applications of this work could attempt to predict the magnitude of an earthquake seconds before it begins by measuring the SNP, vastly improving earthquake Early Warning Systems for populated areas.

▼ Cílem práce bylo vypracování popisu raného stadia hydratace cementové pasty na mikroskopické (resp. mezoskopické) úrovni. Disertace obsahuje teoretický popis procesu tuhnutí cementové pasty, který je podpořen experimentálním měřením úzce souvisícím s nukleačními procesy probíhajícími v daném systému. V práci je formulován fyzikální popis hydratačních procesů pomocí teorie fázových přechodů I. druhu (solidifikace) a nukleační teorie. Použitý model je aplikován na relativně jednoduchý systém (portlandit + voda). Byly určeny základní charakteristiky nukleačního procesu: rozměry kritického zárodku portlanditu, nukleační bariéra, poměrná nukleační rychlost v závislosti na stupni přesycení roztoku molekulami portlanditu a na teplotě. V rámci modifikované titrační metody byla určena časová závislost koncentrace vápenatých iontů v hydratující cementové pastě pro různé hodnoty vodních součinitelů. K doplnění komplexnosti celé práce byly naměřeny i změny elektrické vodivosti hydratující cementové pasty v čase.; The aim of this work was to compile a description of the early stage of cement paste hydration to a microscopic (or mesoscopic) level. This thesis includes a theoretical description of the setting process of cement paste, which is supported by experimental measuments closely related to nucleation processes underway in this system. In this work I have formulated a physical description of the hydration processes with the aid of the theory of type I phase transitions (solidification) and nucleation theory. The used model is applied to a relatively simple system (portlandite + water). The basic charactersitics of the nucleation process were identified: the size of critical clusters of portlandite, the critical free energy and the relative nucelation rate depending on the level of supersaturated portlandite molecule solution and temperature. Within the modified titration method the time dependence of the concentration of calciums ions in hydrating cement paste for various values of w/c ratios was established. To complete the whole process the changes in the electrical conductivity of hydrating cement paste in time were measured. Advisors/Committee Members: Demo Pavel (advisor).

Subjects/Keywords: hydratace; nukleace; portlandit , hydration; nucleation; portlandite
