Using Greet To Analyze Natural Gas Usage In Municipal Fleets, Bradley E. Gibson
Using Greet To Analyze Natural Gas Usage In Municipal Fleets, Bradley E. Gibson
Honors Theses
GREET was used to calculate energy consumption and pollutants emitted from specific fuel/vehicle types when given a specific set of parameters. In this case, the parameters were the type of fuel mix from TVA, the selected vehicle year of 2015, the vehicle weight specified in the heavy-duty vehicle range, and type of simulation technique, which was the Hammersely Sequence Sampling. These inputs, along with seventeen fuel/vehicles mixes, specific pollutants, and cost considerations, were used to investigate the environmental impact of the transition from petrol diesel to natural gas in the municipal fleets of Chattanooga, Tennessee. The energy consumption included coal, …
Outlining The Biocidal Mechanisms Of Synthetic Antimicrobial Peptide Mimics, Tyler D. Brown
Outlining The Biocidal Mechanisms Of Synthetic Antimicrobial Peptide Mimics, Tyler D. Brown
Honors Theses
Each day, antibiotic resistance affects the livelihood of individuals worldwide, especially in relation to hospital-acquired diseases. In an effort to combat this resistance, antimicrobial peptides, small biopolymers produced naturally by multicellular organisms, can be used to selectively eliminate bacteria and have demonstrated great potential as alternatives to conventional antibiotics. Many naturally-occurring antimicrobial peptides possess high concentrations of lysine and arginine amino acid residues, which are protonated and positively-charged at physiological pH. Herein, we describe the design and synthesis of antimicrobial peptide mimics, using amino acid mimics. N-3-aminopropyl methacrylamide (APMA) and 3-guanidinopropyl methacrylamide (GPMA) monomers mimic the amino acid residues lysine …

The Effect Of Co-Solvent And Ordered Lattice Structure On Catalysis Of Biodiesel Production In Microreactors, Benjamin J. D. Kegley
The Effect Of Co-Solvent And Ordered Lattice Structure On Catalysis Of Biodiesel Production In Microreactors, Benjamin J. D. Kegley
Honors Theses
In this study, stable single phase feedstocks for biodiesel production were successfully determined. The addition of free fatty acids, which are considered waste, to the soy bean oil and methanol processing feed as a co-solvent, produces a stable single phase. The single phase feedstock significantly increases initial global rates and supplements the oil with further biodiesel production. A stable single phase feedstock and increased reaction rates are desirable due to the use of continuous heterogeneous biodiesel production in microreactors currently being developed by this research group. Further design improvements to the microreactor design have been determined. Such improvements include the …
Reduction Of Ketoximes To Amines By Catalytic Transfer Hydrogenation Using Raney Nickel And 2-Propanol As Hydrogen Donor, Katherynne E. Taylor
Reduction Of Ketoximes To Amines By Catalytic Transfer Hydrogenation Using Raney Nickel And 2-Propanol As Hydrogen Donor, Katherynne E. Taylor
Honors Theses
Ketoximes successfully underwent hydrogenolysis and hydrogenation under catalytic transfer conditions with Raney Nickel and 2-propanol as a hydrogen donor. Ketoximes were reduced to primary amines when 2% KOH was included in the reaction. In the absence of KOH N-isopropyl-secondary-amines were obtained in good yields.
Utilizing Reversible Addition Fragmentation Chain Transer For The Synthesis Of Polymeric Gene Delivery Vehicles, Jared Spoons
Utilizing Reversible Addition Fragmentation Chain Transer For The Synthesis Of Polymeric Gene Delivery Vehicles, Jared Spoons
Honors Theses
There are many techniques used today to make a variety of polymers but this thesis investigates the reversible addition-fragmentation chain transfer (RAFT) polymerization technique and illustrates the advantages and importance of using RAFT polymerization technique to make the desired polymer. The research focused on two monomer units that were to form the diblock copolymer; the hydrophilic part, oligo(ethylene glycol) methacrylate, and the cationic hydrophobic part 2-diethylaminoethyl methacrylate. The goal was to produce a target diblock copolymer with a Mn value of 44K and a PDI under 1.5 with the block sizes being a 35K Mn OEGMA chain and a 9K …
The Cooling Effect Of Cryotherapy On Power And Accuracy In The Pitching Arms Of Baseball Players, David Kimble Wilbanks
The Cooling Effect Of Cryotherapy On Power And Accuracy In The Pitching Arms Of Baseball Players, David Kimble Wilbanks
Honors Theses
As the human body does work, energy is released in the form of heat. The ability to perform the same action repeatedly and at the same intensity requires energy to be maintained. By preserving energy in sports, a reduction of injuries and an increase in performance duration would most likely be observed. More specifically in sports, for 200 years of baseball history, the pitcher has attempted to keep their arm warm during resting intervals of a game, in belief this would help sustain their level of performance. This study attempted to overturn this view. I hypothesized that by cooling their …
Performance And Stability For Room Temperature Ionic Liquid Membranes For The Dehumidification Of Methane, Dora Frances Sullivan-González
Performance And Stability For Room Temperature Ionic Liquid Membranes For The Dehumidification Of Methane, Dora Frances Sullivan-González
Honors Theses
The biogas production from organic waste—animal, sewage, landfill material— could be a valuable renewable fuel. Before this biogas—predominately bio-methane— can be converted to fuel, it must be dehumidified. Typically membrane-based gas dehumidification uses hydrophilic polymer membrane materials, such as polydimethylsiloxane (PDMS) and cellulose acetate (CA). The main problems with polymer dehumidification membranes are methane loss and the susceptibility of polymer materials to plasticization by H2O. Room temperature ionic liquid membranes (RTIL- membranes), according to recent literature, are not plasticized by water and have large water/CH4 selectivities. We built on the initial literature RTIL-dehumidification data by looking at a series of …
