Photochemical reduction of carbon dioxide in aqueous and ionic liquid solutions in a microreactor with TiO₂ catalyst; experiment and modeling

Creator:: Campbell, Travis J.
Abstract:: Microtechnology was used to study the chemical reduction of dissolved carbon dioxide into useful products. A novel TiO₂ photocatalyst was used to activate the reaction under ultraviolet irradiation. CO₂ was dissolved in aqueous and 50% BMIM-BF₄ (ionic liquid) solutions. The introduction of an ionic liquid increased the solubility of CO₂...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

CO2 reduction in aqueous-ionic liquid solution in microscale-based corona reactor, CO₂ reduction in aqueous-ionic liquid solution in microscale-based corona reactor

Creator:: Miao, Yu
Abstract:: Global warming problem is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Among various methods of CO₂ utilization, conversion of CO₂ to value added chemical products is the most attractive. In this study, a microscale-based corona reactor is introduced for reduction...

Preasymptotic Dispersion : A Theory that Includes Evolution from the Initial Condition

Creator:: Taghizadeh, Ehsan
Abstract:: The objective of this study is to investigate the dispersion of solute matter introduced into a fully developed laminar flow in a circular capillary tube under preasymptotic regimes. For this purpose, we have used the method of volume averaging to upscale microscale balance equations for the case of diffusion-convection transport...

A study of the dynamics and rheology of passive and active suspensions of particles with various geometries

Creator:: Tan, Mingyang
Abstract:: Suspensions of particles in fluids are everywhere in our life, such as paints, pharmacies, food, etc. Suspensions can exhibit properties that common fluids do not possess. For example, the paint needs to flow well when brushing so that it can be smeared on the wall, which is aided by the...

Oxidation of hydrocarbon in a carbon nanotube supported corona discharge in micoreactor : oxidation of ethylene

Creator:: Alanazi, Yousef M.
Abstract:: Population growth driven sustainability issues, including the food resource issue, are pressing problems in need of attention. The goal of the present thesis is to examine the ability of an electric non-thermal plasma based microreactor to destroy ethylene, a known plant hormone responsible for losses in the range of 20%...

Metal Oxide Cluster Chemistries for Next Generation Nanomanufacturing

Creator:: Frederick, Ryan T.
Abstract:: Metal oxide clusters are promising inorganic photoresists in next generation nanomanufacturing because of their potential for high-resolution and low line-edge roughness patterning, and exceptional sensitivity to extreme ultraviolet (EUV) radiation. In EUV patterning, absorption of EUV radiation leads to electron emission that serve as a primary species for driving radiation...

Utilization of Renewable Energy via Thermochemistry

Creator:: Lei, Fuqiong
Abstract:: Utilization of solar energy or wind energy for electricity production is inherently challenging due to the diurnal and seasonal variations and normal intermittency. Effective, high efficiency storage methods need to be developed for further advancing renewable energy utilization. Endothermic chemical processing and thermochemical energy storage can be both employed as...

Numerical Methods for Upscaling Complex Transport Phenomena

Creator:: Taghizadeh, Ehsan
Abstract:: Transport phenomena specially the ones that occur in the various engineering disciplines such as tissue engineering and natural environment are often complex to analyze mostly due to the dynamic and geometric complexities; as such, they have been the subject of an active and intense area of research in past decades....

Chemical Reaction Processes in Microscale-Based Reactors; Mathematical Model and Numerical Simulation of the Fischer-Tropsch Process and Activation of Methane in a Corona Discharge Plasma Reactor

Creator:: Traverso, Andrew C.
Abstract:: Worldwide production of natural gas has surged in the last few decades leading to an economic windfall for many communities, but sometimes these new sources of natural gas are located in geographically isolated locations. These areas are so remote that it isn’t economically feasible to transport this stranded gas to...
