  Citation × Citation Citation Abstract Copy Title: Computational Studies of Environmentally Important Processes at Aqueous Interfaces Author: Shamay, Shachar Year: 2012 Undoubtedly, water is the most abundant and important molecular liquid and is likely the most necessary for life on Earth. The pursuit of understanding water's properties and behaviors has placed it in a unique scientific and even mythical position throughout human history. It is no surprise that much scientific research today centers around this molecule and its interactions with others. The interfacial region between liquid water solutions and other phases is still poorly understood, and only recently have experiments developed to where we can probe this unique environment. Water surfaces exist throughout the Earth's atmosphere and oceans but also make up many of the microscopic interfaces necessary for metabolic processes within living cells. Yet, the influence of water surfaces on the chemistry that drives life and terrestrial processes is still largely unknown, and many research efforts today are attempting to gain insight to this critically important frontier. This dissertation documents several unique computational studies aimed to further our understanding of the complex interactions within a water system and between water and simple, common solutes. Reported herein are the results of molecular dynamics (MD) simulations and computational analysis of interfacial aqueous systems of small hydrated acids, ionic aqueous salt solutions interfaced with a liquid oil, and gas molecules adsorbing onto water surfaces. The composition of the systems chosen for the studies reported in this dissertation reflect environmentally relevant interfaces and also complement recent experimental efforts by the Richmond laboratory. Classical and quantum ab initio MD techniques were used for simulation of the molecular systems and the subsequent analyses provided new information regarding molecular interactions, geometries, orientations, and surface behaviors of water and hydrated interfacial solute molecules. This dissertation includes both previously published and unpublished co-authored material.

  Citation × Citation Citation Abstract Copy Title: Spectroscopic and Thermodynamic Studies of the Adsorption of Atmospherically Relevant Dicarboxylic Acids at the Vapor/Water Interface Author: Blower, Patrick Year: 2013 Many important atmospheric processes are determined by the chemical composition of aerosols, including organic material. Dicarboxylic acids are a commonly detected class of organic material in urban, rural, and remote sites across the globe. Understanding the surface behavior of these molecules is imperative in characterizing the atmospheric fate of these molecules in aerosols, especially at an aerosol surface. In fact, little is known about their orientation, solvation, or pH dependence. This dissertation explores in molecular level detail the concentration and pH behavior of low molecular weight dicarboxylic acids at the air/water interface, which is used as a model for an aerosol surface. The solvation of the carboxylic head groups is shown to be dependent upon the length of the alkyl backbone. Indeed, the solvation of the head groups changes dramatically from very weakly solvated to typical surface solvation to near bulk solvation as the backbone increases. The orientation and conformation at the surface is fully explored to explain these differences in solvation. The pH dependence of surface adsorption is characterized, and it is shown that some acids are only surface active if they are fully protonated while others may still be surface active in singly or fully deprotonated forms. Using a combination of vibrational sum frequency spectroscopy (VSFS), surface tension, and computational modeling, the behavior at the air/water interface of four of the most relevant surface-active dicarboxylic acids (malonic, succinic, glutaric, and adipic acid) is completely described. VSFS, a surface specific optical technique, provides details about the solvation, orientation, and number density at the surface while surface tension measurements provide corollary information about the surface density. The use of computational modeling aids and confirms the spectral analysis while also providing molecular level details about the surface adsorption of the acids studied. By investigating the concentration and pH dependence of these molecules, molecular level detail is obtained which enables a complete description of these acids at an air/water interface and provides pertinent surface information on these atmospherically important organic molecules. This dissertation includes both previously published and unpublished co-authored material.

  Citation × Citation Citation Abstract Copy Title: Supramolecular Modification of Mesoscale Materials Author: Fontenot, Sean Year: 2012, 2013 The process of surface modification allows us to combine the structural advantages of materials with the chemical functionality of organic compounds. Attachment of functional organic molecules to surfaces of high surface area substrates yields materials having dense chemical functionality. Materials with meso- and nanoscale features are often used as support substrates because their small-scale features provide very high surface area. Mesoporous silica is one of the most chemically accessible mesoscale materials, and the well-established chemistries of its production and modification lead to controlled pore structure and rapid kinetics. Such materials have seen use as sorbents for environmental remediation of contaminated water. For this application, their high degree of functionality and high-affinity surface chemistries permit a relatively small amount of material to effectively treat a large volume of water. The many advantages of these highly engineered materials come at a relatively high economic cost. The high-affinity chemical functionalities that provide these materials with unprecedented efficiencies also make them correspondingly more difficult to recycle. One-time utilization of these materials makes the cost-per-use high which consequently limits their economically viable applications. The goal of this work has been to explore surface chemistries that will allow high performance, regenerable or recyclable sorbent materials. Shifting from a single-use material to a regenerable platform in which the mesoscale supports are recycled may lower the environmental and economic costs of the material while retaining the advantageous properties of the meso- and nanostructured materials. We chose to approach this goal by developing non-covalent, supramolecular surface modification techniques as alternatives to current surface modification techniques which, almost without exception, are based on covalent modification motifs. Non-covalent attachment of organic molecules to surfaces allows us to avoid the necessity of optimizing the attachment for each class of organic molecule as well as avoid protection and de-protection procedures necessary to attach delicate or reactive functional groups to surfaces. In this way, supramolecular modification processes reduce the cost of material research and development in addition to the costs of material production and use.

Title: Supramolecular Modification of Mesoscale Materials Author: Fontenot, Sean Year: 2012, 2013 The process of surface modification allows us to combine the structural advantages of materials with the chemical functionality of organic compounds. Attachment of functional organic molecules to surfaces of high surface area substrates yields materials having dense chemical functionality. Materials with meso- and nanoscale features are often used as support substrates because their small-scale features provide very high surface area. Mesoporous silica is one of the most chemically accessible mesoscale materials, and the well-established chemistries of its production and modification lead to controlled pore structure and rapid kinetics. Such materials have seen use as sorbents for environmental remediation of contaminated water. For this application, their high degree of functionality and high-affinity surface chemistries permit a relatively small amount of material to effectively treat a large volume of water. The many advantages of these highly engineered materials come at a relatively high economic cost. The high-affinity chemical functionalities that provide these materials with unprecedented efficiencies also make them correspondingly more difficult to recycle. One-time utilization of these materials makes the cost-per-use high which consequently limits their economically viable applications. The goal of this work has been to explore surface chemistries that will allow high performance, regenerable or recyclable sorbent materials. Shifting from a single-use material to a regenerable platform in which the mesoscale supports are recycled may lower the environmental and economic costs of the material while retaining the advantageous properties of the meso- and nanostructured materials. We chose to approach this goal by developing non-covalent, supramolecular surface modification techniques as alternatives to current surface modification techniques which, almost without exception, are based on covalent modification motifs. Non-covalent attachment of organic molecules to surfaces allows us to avoid the necessity of optimizing the attachment for each class of organic molecule as well as avoid protection and de-protection procedures necessary to attach delicate or reactive functional groups to surfaces.

  Citation × Citation Citation Abstract Copy Title: Water-smart Urban Design: Conserving Potential in Swimming Pools Author: Antonelli, Eleni Year: 2016 Dry weather dominates several U.S. states, and some of them experience even long-term droughts. Yet, more than 10.6 million swimming pools exist in the U.S., and over 43,000 of them are in greater Los Angeles. Since roughly 100% of their water evaporates on a yearly basis, pool water evaporation accounts for a significant amount of water being wasted every day. Several studies have been conducted to create a proper equation for the evaporation rate on a pool surface, based on the wind speed, water temperature, and relative humidity. This thesis will address a research gap that was found in exploring the way the surroundings of the pool can affect its evaporation rate. In particular, this study examines the relation of the urban design to the evaporation rate of outdoor swimming pools by studying the way the housing type of a neighborhood affects the wind speed over the neighborhood’s pool surfaces.

  Citation × Citation Citation Abstract Copy Title: Functionalized Nano-structured Silicas for Trace Collection from Natural Waters Author: Nell, Kara Year: 2016 Throughout this body of work, three classes of sorbent materials were created and optimized, each designed to selectively capture organics or desired metals from natural water sources. These target species included toxic heavy metals, uranium, rare earths, and simple organics, such as benzene. Each class of sorbent materials is functionalized nanostructured silicas, created by the development of several functionalization methods: utilizing thiol-ene click chemistry, aromatic interactions, and the formation of inclusion complexes. Thiol-ene click surface modification gave rise to sorbent materials with impressive affinities for both soft metals, such as gold, and harder metals, such as uranium and rare earth elements. Applications of these materials for aqueous mining of uranium and rare earth elements from various natural water sources are presented. Two classes of materials based on supramolecular functionalization methods were prepared. In the first class, aromatic interactions allowed for surface functionalization with thiol containing aryl ligands. These materials proved to have an excellent affinity for heavy metals from natural waters, and hold promise for regenerable nanostructured silica sorbents. The second class of materials utilizes the ability of β-cyclodextins to form inclusion complexes with small molecule organics, such as benzene. The formation of inclusion complexes drove both surface functionalization and the capture of small molecule organics from aqueous solutions. This work serves to inspire the development of novel functionalized nanostructured sorbents for trace collection of toxic organics from aqueous streams. These supramolecular methods for surface medication can be expanded to nanomaterials at large. This dissertation includes both previously published/unpublished and co-authored material.

To circumvent this restriction, I have contstructed and characterized a two-dimensional metafluid, so-called because its constitutive dynamics are derived not from atoms and molecules but from macroscopic, chaotic surface waves excited on a vertically agitated fluid. Unlike in conventional fluids, the viscosity and temperature of this metafluid are independantly tunable. Despite this unconventional property, our system is surprisingly consistent with equilibrium thermodynamics, despite being constructed from macroscopic, non-equilibrium elements. As a programmable material, our metafluid represents a new platform on which to study complex phenomena such as self-assembly and pattern formation. We demonstrate one such application in our study of short-chain polymer analogs embedded in our system.

  Citation × Citation Citation Abstract Copy Title: Physical Oceanography, Larval Dispersal, and Settlement Across Nearshore Fronts Author: Jarvis, Marley Year: 2015 The larvae of coastal species interact with nearshore currents that are complex and can alter dispersal. I investigated two sites in southern Oregon with different nearshore hydrodynamics: the first site, Sunset Bay, is a small cove with a topographic front that extends across the mouth during upwelling-favorable winds. Using holey sock drogues at 1.5 m and 5.5 m depths and surface drifters at 10 cm depth, I found that, when the front was present, water at 1.5 m was retained within the bay whereas water was exchanged across the front at a depth of 5.5 m. Surface drifters indicated a surface convergence. Surface plankton tows on either side and within the frontal convergence (a shore-parallel foam line) found significantly higher concentrations of barnacle cyprids, crab megalopae and zoea, polychaete larvae, platyhelminthes juveniles, isopods, amphipods, harpacticoid copepods, and fish eggs. Crustacean nauplii (barnacle, euphausiid, and copepod) and calanoid copepods were not concentrated in the convergence, and when the front and foam line were absent, no taxa were concentrated. Plankton tows taken within the foam line as it dissipated shoreward during a wind-reversal event found that concentrations of cyprids, megalopae, and gastropod veligers remained high as the foam line moved, suggesting that it acts as a moving convergence propagating competent larvae shoreward. I measured settlement of two taxa at Sunset Bay and Shore Acres, an open-coast site <2 km away. Barnacle settlement measured every other day from June-September 2013 was significantly cross-correlated with the maximum daily tidal height at lags of -2 days at Sunset Bay and +2 and +4 days at Shore Acres. Settlement was also significantly negatively cross-correlated with wave height at a lag of -4 days at Sunset Bay. Coralline algae settlement measured during eight 48-hr periods in July-August 2013 was significantly negatively correlated with wave height (n = 8, R2 = 0.76, P = 0.0049) at Shore Acres but not at Sunset Bay. Despite the close proximity of the Sunset Bay and Shore Acres sites, settlement patterns differed between taxa, suggesting that differences in nearshore hydrodynamics might affect the supply of water and larvae to shore. This dissertation includes unpublished co-authored material.

Using satellite data sets we quantify properties and distributions of icebergs in three fjords with varied properties: Sermilk, Rink Isbræ, and Kangerdlugssûp Sermerssua. Total iceberg volumes in summer in the three fjords average 6.43, 1.69, and 0.19 km^3, respectively, and we calculate cumulative submerged surface areas of iceberg faces to be 213, 55.2, and 7.57 km^2, respectively. We calculate a freshwater flux from iceberg melt of 0.009 – 0.083 m^3 d^-1 in Sermilik Fjord, suggesting a strong potential of iceberg melt water to influence water properties. Properties of icebergs and size distributions are influenced by calving style and grounding line depths of parent glaciers. Variations are represented in the coefficients of generalized Pareto distributions which best describe size distributions in the fjords.

  Citation × Citation Citation Abstract Copy Title: Seasonal Dynamics of Methane Pathways Along a Hydrogeomorphic Peatland Gradient Author: McAllister, Steven Year: 2016 Northern peatlands occupy a very small proportion of the Earth’s surface but contain nearly a third of the world’s soil organic carbon. These wetland systems produce substantial fluxes of CH4, a potent greenhouse gas, and are expected to experience particularly high annual mean temperature increases as global climate change proceeds, which could result in a significant positive feedback. Using radioisotope labeling, we quantified the rates of two pathways of CH4 production in six sites in northern Michigan along a physiochemical and ecological gradient that characterizes northern peatlands. We found that the rates of these two pathways displayed markedly different dynamics in space and time and that the hydrogenotrophic pathway, previously presumed to be less significant in these systems, can increase substantially and become dominant across the landscape when water tables are high. Quantifying these two pathways provides critical insight into understanding dynamics of CH4 production in northern peatlands.

  Citation × Citation Citation Abstract Copy Title: Linking Nature and History Author: Goldberg, Landon, Ribe, Robert, Finney, Kevin Year: 2017 Albany has a vibrant historic downtown and a beautiful waterfront park. However, the links between the two are not particularly frequent, inviting, or pedestrian- friendly. This proposal analyzes natural site conditions and the existing built environment to locate the optimal spots where such links could most productively be strengthened. Surface geology conditions, topography, existing railroad crossings, view corridors from public transit, and vehicle circulation factors converged to suggest several points of intervention. This proposal recommends the addition of crosswalks, bus shelters, entrance markers such as arches and planter boxes, a new small park, and stormwater quality planters in order to make the connections between the downtown and the riverfront safer, more pleasant, more active, and more visible. Additionally, this proposal o ers suggestions on the possible redevelopment of Water Street to enhance that transitional zone. Two possible zoning priorities are suggested: The street could become an extension of the park, providing a larger open space that can host more recreation opportunities and services, or alternatively, it could be a place for mixed-use development, which could draw people from the shops of historic downtown to enjoy co ee or dinner along the water, and will bring more residents to the area who can shop downtown and enjoy the river. Either proposal would make the crossings between the waterfront and the downtown more enjoyable and desirable.

  Citation × Citation Citation Abstract Copy Title: Modeling Circulation Dynamics and Submarine Melt in Greenland Fjords Author: Carroll, Dustin Year: 2017 Meltwater accumulated on the Greenland Ice Sheet drains to glacier beds, discharging into fjords hundreds of meters below sea level. The injection of meltwater at depth generates an upwelling plume that entrains warm ocean water as it rises along the terminus, increasing submarine melt and driving a fjord-scale exchange flow. However, due to sparse ocean-glacier observations, we lack a process understanding of how plumes control fjord circulation and submarine melt. Combining numerical modeling, theory, and observations, this dissertation investigates near-glacier plume dynamics, the influence of glacier depth on plume structure and submarine melt, and the role of fjord-glacier geometry on circulation in tidewater glacier fjords. In Chapter II, I use buoyant plume theory and a nonhydrostatic, three-dimensional ocean–ice model to investigate the sensitivity of plume dynamics to subglacial discharge, turbulent diffusivity, and conduit geometry. Large discharges result in plumes with positive temperature and salinity anomalies in the upper water column. Fjord circulation is sensitive to conduit geometry; distributed subglacial discharge results in a stronger return flow of warm water toward the terminus. In Chapter III, I use buoyant plume theory, initialized with realistic ranges of subglacial discharge, glacier depth, and ocean stratification, to investigate how plume structure and submarine melt vary during summer months in 12 Greenland fjords. Grounding line depth is a primary control on plume-induced submarine melt: deep glaciers produce warm, salty subsurface plumes that undercut termini, and shallow glaciers produce cold, fresh surface-confined plumes that can overcut. Finally, in Chapter IV, I use regional-scale numerical ocean simulations to systematically evaluate how fjord circulation forced by subglacial plumes, tides, and wind stress depends on fjord width, glacier depth, and sill height. Glaciers grounded below sill depth can draw shelf waters over a shallow sill and into fjord basins with seasonal subglacial discharge; this process is independent of external shelf forcing. These results underscore the first-order effect that subglacial discharge and fjord-glacier geometry have in controlling fjord circulation and, thus, ocean heat flux to the ice. This dissertation includes previously published and co-authored material.

  Citation × Citation Citation Abstract Copy Title: Controls on the Kinematics of Slow-moving Landslides from Satellite Radar Interferometry and Mechanical Modeling Author: Handwerger, Alexander Year: 2015 Landslides display a wide variety of behaviors ranging from slow persistent motion to rapid acceleration and catastrophic failure. Given the variety of possible behaviors, improvements to our understanding of landslide mechanics are critical for accurate predictions of landslide dynamics. Recent advances in remote sensing techniques, like satellite radar interferometry (InSAR), now enable high-resolution spatial and temporal measurements that provide insight into the mechanisms that control landslide behavior. In this dissertation, I use InSAR and high-resolution topographic data to identify 50 slow-moving landslides in the Northern California Coast Ranges and monitor their kinematics over 4 years. These landslides have similar mechanical properties and are subject to the same external forcings, which allows me to explore geometrical controls on kinematics. Each landslide displays distinct kinematic zones with different mean velocities that remain spatially fixed. Because these deformation patterns are sensitive to subsurface geometry, I employ a mathematical model to infer landslide thickness and find that these landslides exhibit a highly variable thickness and an irregular basal sliding surface. Time series analysis reveals that each landslide displays well-defined seasonal velocity changes with a periodicity of ∼ 1 year. These velocity variations are driven by precipitation- induced changes in pore-water pressure that lag the onset of rainfall by up to 40 days. Despite significant variations in geometry, I find no systematic differences in seasonal landslide behavior. To further explore how stress perturbations control landslide motion, I develop a mechanical model that reproduces both the displacement patterns observed at slow-moving landslides and the acceleration towards failure exhibited by catastrophic events. I find that catastrophic failure can only occur when the slip surface is characterized by rate-weakening friction and its spatial dimensions exceed a critical nucleation length that is shorter for higher effective stresses. These model simulations support my conclusions from the remote sensing analysis but also provide insight into the long-term evolution of landslides. This dissertation includes both previously published and unpublished co- authored material.

  Citation × Citation Citation Abstract Copy Title: STRUCTURE-ACTIVITY RELATIONSHIPS IN NI-FE (OXY)HYDROXIDE OXYGEN EVOLUTION ELECTROCATALYSTS Author: Batchellor, Adam Year: 2017 The oxygen evolution reaction (OER) is kinetically slow and hence a significant efficiency loss in electricity-driven water electrolysis. Understanding the relationships between architecture, composition, and activity in high-performing catalyst systems are critical for the development of better catalysts. This dissertation discusses areas both fundamental and applied that seek to better understand how to accurately measure catalyst activity as well as ways to design higher performing catalysts. Chapter I introduces the work that has been done in the field to date. Chapter II compares various methods of determining the electrochemically active surface area of a film. It further discusses how pulsed and continuous electrodepostition techniques effect film morphology and behavior, and shows that using a simple electrodeposition can create high loading films with architectures that outperform those deposited onto inert substrates. The reversibility of the films, a measure of the films transport efficiency, is introduced and shown to correlate strongly with performance. Chapter III uses high energy x-ray scattering to probe the nanocrystalline domains of the largely amorphous NiFe oxyhydroxide catalysts, and shows that significant similarities in the local structure are not responsible for the change in performance for the films synthesized under different conditions. Bond lengths for oxidized and reduced catalysts are determined, and show no significant phase segregation occurs. Chapter IV seeks to optimize the deposition conditions introduced in Chapter II and to provide a physical representation of how tuning each of the parameters affects film morphology. The deposition current density is shown to be the most important factor affecting film performance at a given loading. Chapter V highlights the different design considerations for films being used in a photoelectrochemical cell, and how in situ techniques can provide information that may otherwise be unobtainable. Chapter VI serves as a summary and provides future directions. This dissertation contains previously published coauthored material.

  Citation × Citation Citation Abstract Copy Title: After the Flow: Landscape Response to the Emplacement of Holocene Lava Flows, Central Oregon Cascades, USA Author: Deligne, Natalia Year: 2012 Effusive volcanic eruptions repave landscapes rapidly with lava flows, resetting the underlying landscape and ecosystem. The unique physical properties of lava pose interesting challenges for recovery, as lava flows can be highly permeable while lava itself is dense, sterile, and generally inhospitable towards life. This dissertation examines two aspects of landscape recovery following lava flow emplacement: (1) hydrologic adaptation of surface and groundwater to recent volcanism and (2) plant colonization of young lava flows. I examine two sites in the central Oregon Cascades: the c. 3 ka Sand Mountain volcanic field (SMVF), located in the headwaters of the McKenzie River, a critical water resource for the state of Oregon, and the c. 1.5 ka Collier Cone lava flow, originating on the north flanks of North Sister volcano. My investigation of the SMVF and upper McKenzie River watershed reveals a complex volcanic history with profound impacts on the configuration and short-term discharge of the McKenzie River: lava flows from the SMVF and other Holocene vents have buried, dammed, and altered the path of the McKenzie River. Moreover, given the large groundwater contribution from the SMVF to the McKenzie River, I estimate that SMVF activity caused McKenzie River discharge in present-day Eugene, Oregon to decrease by up to 20% for days to months at a time; future regional mafic volcanic activity could have a similar impact. The SMVF and the Collier Cone lava flow are notable for the juxtaposition of barren exposed lava and mature forests on the same or similarly aged lava flows. I use a combination of LiDAR analysis, field observations, and soil characterization to examine soil and vegetation at these two sites and find that the presence of an external soil source greatly facilitates plant establishment, growth, and survival. Here, external soil sources are syn- or post-eruptive tephra (SMVF) or flood-borne deposits (Collier Cone lava flow). External soil appears to provide a substrate for plants to grow in along with key nutrients and sufficient moisture; overall, external soil sources are key for the initial recovery following an effusive volcanic disturbance.
