Density Function Theory Study of CO2 Dissociation on Ni and Ni Based Alloy Surface

Creator:: Zhao, Weinan
Abstract:: The corrosion and degradation of Ni and its alloys in supercritical carbon dioxide (Sc-CO2) is an emerging issue for material selection and implementation of Sc-CO2 thermal cycles in industry. In this study, we apply density functional theory (DFT) to study the initial steps of carburization of the Ni (111) surface...

Density Functional Theory Investigation of CH Coupling and CH Hydrogenation Reactions on Different Cobalt Surface Facets and Fischer-Tropsch Temperature Swing Reactor Optimization

Creator:: Petersen, Dennis F.
Abstract:: Fischer-Tropsh Synthesis is a chemical process that converts CO and H₂ (syngas) into long stable hydrocarbon chains to use as fuel. This process suffers from large product distribution that requires expensive post processing. In this study, the reaction mechanism of hydrocarbon chain growth on Co is investigated on different surface...

Solar-driven Dry Reforming Reaction in a Milli-scale Reactor

Creator:: Wang, Yige
Abstract:: Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...

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...

Down-Shifting Nanoparticles and Anti-reflective Nanoparticles Co-Coating Applied on Top Glass Cover of Silicon-Based Solar Panels

Creator:: Jing, Qun
Abstract:: Photoluminescence (PL) materials have attracted a lot of attention in last several decades. Recently PL materials, which can convert low-efficiency Ultraviolet (UV) or Infrared (IR) light to high-efficiency visible light, have been widely applied in the research of improving conversion efficiency of solar cell. As one of the most common...

Development of Temperature Stable Dielectric Materials Based on Lead Bismuth Perovskite Solid Solutions

Creator:: Colton, Zachary D.
Abstract:: High energy density ceramic capacitors with temperature stable permittivity across -150°C to 300°C are desired for a wide variety of electronic devices. Traditional dielectrics such as barium titanate provide a high permittivity but that permittivity is strongly temperature dependent over this specified temperature range. The goal of this work is...

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...

Structure-Property Relationships of Supported Palladium and Rhenium Oxide for the Alkane Rearrangement of Hydrocarbons and Deconstruction of Polyethylene via Tandem Dehydrogenation and Olefin Metathesis

Creator:: Moore, Selena C.
Abstract:: The rapid accumulation of plastic waste in landfill, waterways and oceans is becoming a critical problem, one that current recycling technologies are not capable of solving. Recent proposed approaches in the depolymerization of waste plastics employ an Olefin-Intermediate Process (OIP), where feedstocks like polyolefin plastics are ‘activated,’ producing an olefin...
