Oxidation Of Carbon Monoxide Over Ceria And Alumina Supported Palladium Catalysts, John Davis Gary
Oxidation Of Carbon Monoxide Over Ceria And Alumina Supported Palladium Catalysts, John Davis Gary
Theses and Dissertations
Palladium catalysts on both Al2O3 and CeO2, supports were studied for efficacy in low temperature carbon monoxide oxidation. Calcination temperatures were varied between 500-900°C for alumina supported catalysts and shown to have no significant difference in activity. X-Ray Photoelectron Spectroscopy studies revealed structural changes associated with palladium states and reacted catalysts and displayed a change from palladium oxide (PdO) to native palladium oxide (PdOx) and elemental palladium (Pd). Activity studies were conducted on all catalysts synthesized and indicated that Pd/Al2O3 achieved 100% CO conversion at 150°C when calcined at 500°C and pretreated with reduction process. Pd/CeO2 showed higher activity and …

Al Planning Assistant For Scheduling Daily Activities, Priyanka Ahuja
Theses and Dissertations
Artificial conversational agents are software agents that can interact with humans in the way humans do. Siri Cortana, and Alexa are examples of intelligent agents that can help us with almost all the basic tasks. These agents are smart enough to do the basic tasks, but not as much when it comes to complex tasks, such as analyzing traffic data, reviewing scheduling conflicts, rescheduling meetings while resolving conflicts, and offering suggestions based upon data analyses (e.g. traffic patterns, weather, etc.) The actual potential of dialogue-based task agent potential remains untapped. The reason is the fact agents lack the ability to …
Stress Levels Of Cs1 Students During Programming- Measurement And A Cause And Effect Analysis, Gopi Satya Sainadh Raju Sarikonda
Stress Levels Of Cs1 Students During Programming- Measurement And A Cause And Effect Analysis, Gopi Satya Sainadh Raju Sarikonda
Theses and Dissertations
Stress is a kind of feeling we experience when we are under pressure. Stress is the word that we use when we feel that we are overloaded mentally in our thoughts and wonder whether we can cope with those placed upon us. The effects of stress are different for different people when we take their age, profession, gender and other aspects into consideration. Many studies show that stress in a learning environment impacts learning negatively. In this thesis, the role of stress on students in an introductory programming course (CS1) at CSU has been explored. Introductory programming course has a …
Antibiotic Effects Of Dimethyl Sulfoxide And Synthetic Polyphenols On E. Coli Cells, Camila Cardenas
Antibiotic Effects Of Dimethyl Sulfoxide And Synthetic Polyphenols On E. Coli Cells, Camila Cardenas
Theses and Dissertations
There is increasing interest in polyphenols due to their potential medicinal and antibiotic applications. Naturally occurring polyphenols, such as curcumin, have garnered tremendous attention. However, synthetic polyphenols commonly used in biochemistry experiments have not been sufficiently explored. The purpose of this study is to determine the effect of dimethyl sulfoxide on the cellular uptake of synthetic polyphenols. Three synthetic polyphenols (Phenol Red, Congo Red, and Bromophenol Blue) were tested for their antibiotic properties and compared to the antibiotic activity of curcumin. Our results show that phenol red does not interact with the bacterial membrane even in the presence of 30% …
Catalytic Oxidation Of Methane Over Alumina Supported Palladium Oxides, Jacqueline Michelle Mcguire
Catalytic Oxidation Of Methane Over Alumina Supported Palladium Oxides, Jacqueline Michelle Mcguire
Theses and Dissertations
The objectives of this research include development and characterization of alumina supported palladium oxide catalysts for low temperature catalytic oxidation of methane. The catalysts were prepared by various methods and then characterized and screened to select the best catalyst for further studies. A 5% (wt/wt) Pd/y-AhCb catalyst prepared by an improved vortex-assisted incipient wetness method showed the best activity of 94% (mol/mol) methane conversion at 325 °C. The active surface species was found to be PdO and Pd native oxides (PdNtv) as confirmed by X-ray Photoelectron Spectroscopy and activity studies. The y-AhCb support played an integral role in the formation …
Correlation Of Aqueous Solubility And Anti-Cancer Activity Of Novel Triazolium And Imidazolium Salts, Jared J. Bies
Correlation Of Aqueous Solubility And Anti-Cancer Activity Of Novel Triazolium And Imidazolium Salts, Jared J. Bies
Theses and Dissertations
Novel triazolium, imidazolium, and benzimidazolium salts are known to possess anti-cancer properties and have potential as cancer therapeutics. This thesis describes the aqueous solubility and the differential activity of N,AT-bis-substituted-l,2,4-triazolium bromide salts and N/N'-bis(naphthylmethyl)imidazolium bromide salts against MDA-MB-468 breast cancer cells and PC-3 prostate carcinomas. Using a microscale technique, the partition coefficient (log P) of each salt was determined. The log P value was explored to determine the bioavailability of each derivative.
Carbon Limitation In Periphytic Algal Wastewater Treatment Systems, Brandon J. Furnish
Carbon Limitation In Periphytic Algal Wastewater Treatment Systems, Brandon J. Furnish
Theses and Dissertations
As global eutrophication poses an ever increasing threat to water quality new techniques must be implemented to improve the sustainability of natural resource consumption. Wastewater treatment facilities (WWTF) are designed to destroy pathogens, remove particulates, lower oxygen demanding substances, and reduce nutrients from influent waste water to avoid the degradation of receiving waters. WWTF are generally effective, however they are mostly inadequate at removing nutrients. When wastewater derived nutrients such as nitrate and phosphate are discharged to receiving waters, they stimulate algal blooms. Algal blooms can reduce dissolved oxygen, block sunlight for submerged aquatic plants, and render state waters unusable …
