Production Of Biobutanol From Biomass Using Novel Membrane Reactor: A P3 Experience, Ellen Draehn
Production Of Biobutanol From Biomass Using Novel Membrane Reactor: A P3 Experience, Ellen Draehn
Chemical Engineering Undergraduate Honors Theses
Producing biobutanol from a waste product on a large scale is a novel idea. Because of this, there is very little research available in this area. Previous fermentation research has primarily focused on the production of ethanol or biobutanol using cellulosic or agricultural feed stocks. The Phase I research team, Team R azorbacks E ngineering FU el S olutions for E veryone (Team REFUSE), sought to design a fermentation process that would produce butanol from food waste. Team REFUSE cultivated a partnership with Chartwells, the campus food service provider for the University of Arkansas, for the acquisition of food waste. …

Proximate Characterization And Lycopene Determination In Bitter Melon Seed Aril, Luis Raul Jimenez Interiano
Proximate Characterization And Lycopene Determination In Bitter Melon Seed Aril, Luis Raul Jimenez Interiano
Chemical Engineering Undergraduate Honors Theses
Bitter melon aril is the mucilage covering the fruit's seeds which could contain beneficial dietary ingredients. The bright red color of bitter melon aril suggests that it could contain lycopene. The purpose of this study was to determine the proximate composition of bitter melon aril and to explore this material as a potential rich source of lycopene that has health benefits. Bitter melon aril from Sri Lanka, harvested in Arkansas, USA in 2005, 2006, and 2007 was analyzed. An investigation to develop an extraction method for lycopene from bitter melon was performed using liquid-liquid and a polar liquid extraction. The …
Understanding The Effects Of Hydrophobicity For The Detection Of Methylated Dna By Microchannel Electrophoresis, Micah Fritsche
Understanding The Effects Of Hydrophobicity For The Detection Of Methylated Dna By Microchannel Electrophoresis, Micah Fritsche
Chemical Engineering Undergraduate Honors Theses
DNA methylation is an epigenetic mechanism used for long - term silencing of gene expression. This silencing of gene expression can be involved in the down regulation of genes involved in apoptosis, which is a process of regulated cell death, and this inability to break down cells can ultimately lead to tumor formation in cancer. Methylation of DNA follows a certain pattern through developmental stages of an individual, and this pattern is normally maintained throughout that individual's life. However, in the DNA of older individuals, this methylation is commonly seen to be altered. This altered pattern of methylation can be …
Oil Recovery Through Deemulsification Research : Separation Of Water From Emulsified Oil, Aaron Russell, Matthew S. Clay, Christopher A. Cox, Jessica E. Nichols, Summer Scott, Sirikarn Surawanvijit
Oil Recovery Through Deemulsification Research : Separation Of Water From Emulsified Oil, Aaron Russell, Matthew S. Clay, Christopher A. Cox, Jessica E. Nichols, Summer Scott, Sirikarn Surawanvijit
Chemical Engineering Undergraduate Honors Theses
In an effort to improve the environment, there is a need to recover and reuse the oil and water components of lubricating emulsions used in copper drawing and rolling processes. The Freeport-McMoRan Copper and Gold Inc. copper rod mill located in El Paso, TX was chosen as the site location for this project. It is one of the largest rolling and drawing operation facilities in the world, and it meets the established criteria set by Project ORDER. A large facility generates an average of 8,400 gallons of spent lubricant per day. The WERC emulsion sample contains 98 v% water and …
Exploring The Potential For Electromangetophoretic Separation, Thomas Lewis
Exploring The Potential For Electromangetophoretic Separation, Thomas Lewis
Chemical Engineering Undergraduate Honors Theses
Current research in mircofluidic technology is underway to develop automatic micro-analyzing chips for medical diagnostic testing. Diagnostic testing often requires separation of specific biological particles from a sample, and many of these molecules contain electric or magnetic properties. This project investigates the potential for separation in electromagnetophoretic and magnetophoretic microfluidic technology. In electromagnetophoresis, the Lorentz force acting on a current carrying medium in a homogeneous magnetic field creates a pressure gradient in the fluid, resulting in an applied force to particles present in the separation medium. This force causes the particle to have a velocity component that is perpendicular to …
A Study Of Inhomogeneity Effects On Packed High Performance Liquid Chromatography Columns, Tyler House
A Study Of Inhomogeneity Effects On Packed High Performance Liquid Chromatography Columns, Tyler House
Chemical Engineering Undergraduate Honors Theses
The packing quality of a High Performance Liquid Chromatography column has significant impact on the resulting separations. In practice, problems in a packing occur through normal usage of a column. Resulting chromatograms from inhomogeneities exhibit varying problems such as extreme tailing and double peaks. Early detection of such problems is critical to fixing problems before their effect harms efficiency, but a fully developed theory of how inhomogeneities affect separations does not exist. The purpose of this work was to experimentally characterize HPLC column inhomogeneities and to begin preliminary simulations of HPLC columns with the computer simulation package STAR-CD. To do …
Conversion Of Biomass Resource To Useful Forms Of Energy And Other Products, Steven Jennings
Conversion Of Biomass Resource To Useful Forms Of Energy And Other Products, Steven Jennings
Chemical Engineering Undergraduate Honors Theses
The United States is facing increasing pressure to find renewable energy sources due to rising energy costs. With world energy demand at an all time high, renewable energy has been thrust into the forefront of research as a means to mitigate this looming crisis. Throughout the United States, there is a large quantity of agricultural biomass that could be used to generate energy and lessen the dependence on diminishing resources. Specifically, animal feeding operations (AFOs) such as dairies generate large amounts of cow manure, which, when improperly handled, causes both air and water pollution. Currently, most manure is temporarily stockpiled …
