Battery Application Of Silver Molybdate Materials, Brendan Michael Godsel

Undergraduate Honors Papers

As the demand for renewable energy grows, the investigation of potential battery materials continues to progress hastily. Many devices and machines of present day are operated by battery technology, and their energy requirements warrant which kinds of batteries will power them. The battery in a phone requires hundreds, possibly thousands, of uses and needs to be able to recharge quickly. The battery in the implantable cardiac defibrillator (ICD), the battery by which this product was inspired, is only used once, but it must last years before it is replaced. The cathode of the ICD battery is comprised of a silver …

The Negotiator's Role In A Buyer-Seller Game, Joseph Gaudy

Graduate Theses and Capstone Projects (excluding DNP)

In game theory, buyer-seller games rarely utilize a negotiating third party. Any negotiations are typically conducted by the buyer and seller. This study, motivated by the real estate market, uses sequentially and simultaneously played game models to explore the influence a self-interested, negotiating, third party has on player payoffs. For the sequential model, a game tree is utilized to demonstrate player actions, preferences, and outcomes. The weak sequential equilibrium is calculated using Gambit[1] and shows optimality in player payoffs to exist when the seller’s and realtor’s strategies align according to the current market. For the simultaneous model, expected payoff functions …

Cybersecurity In The Classroom: Bridging The Gap Between Computer Access And Online Safety, Andrew Malecki

Cyber Security Capstone Research Project Reports

According to ISACA, there will be a global shortage of 2 million cybersecurity professionals worldwide by 2019. Additionally, according to Experian Data Breach Resolution, as much as 80% of all network breaches can be traced to employee negligence. These problems will not solve themselves, and they likewise won’t improve without drastic action. An effort needs to be made to help direct interested and qualified individuals to the field of cybersecurity to move toward closing this gap. Moreover, steps need to be made to better inform the public of general safety measures while online, including the safeguarding of sensitive information.

Measurement Of The Longitudinal Double-Spin Asymmetry For Neutral Pion Production In Polarized Proton Collisions At √S = 510 Gev, Taegyun Kim

Physics & Astronomy Honors Papers

Beyond the valence quarks' spin contribution to the total spin of a proton, gluon and sea quark contributions are becoming clear as well. For proton+proton collisions at a center of mass energy of 510 GeV , neutral pion production is dominated by gluon-gluon and gluon-quark scattering. An avenue to constrain the gluon polarization is the asymmetry, A_LL, in the production of neutral pions from collisions of longitudinally spin-polarized proton beams. Our experiment was performed with the STAR detector at the Relativistic Heavy Ion Collider (RHIC), unique for its ability to collide spin-polarized proton beams. The Endcap Electromagnetic Calorimeter …

Mutagenic And Spectroscopic Investigation Of Ph Dependent Cooa Dna Binding, Brian R. Weaver

Chemistry Honors Papers

The carbon monoxide (CO) sensing heme protein, CooA, is a transcription factor which exists in several bacteria that utilize CO as an energy source. CooA positively regulates the expression of coo genes in the presence of CO such that the corresponding proteins may metabolize CO. The present studies have yielded the unexpected result that Fe(III) CooA binds DNA tightly at pH < 7, deviating from all previously reported work which indicate that CooA DNA binding is initiated only when the exogenous CO effector reacts with the Fe(II) CooA heme. This observation suggests that the disruption of one or more salt bridges upon effector binding may be a critical feature of the normal CooA activation mechanism. To test this possibility, several protein variants that eliminated a selected salt bridge for the CooA homolog from Rhodospirillum rubrum were prepared via site-directed mutagenesis. Samples of these variant proteins, which were overexpressed in Escherichia coli, were then characterized by spectroscopic methods and functional assays to investigate the impact these mutations had on CooA heme coordination …

A Simulation Of Anthropogenic Mammoth Extinction, Matthew Klapman

Undergraduate Honors Papers

There are multiple hypotheses as to why the Columbian Mammoth (Mammuthus columbi) and other megafauna in North America went extinct relatively recently and relatively quickly. The most popular of which are disease, climate change, meteorite strikes, and over hunting by humans [2, 9]. There is evidence to show that a combination of factors contributed to the megafaunal extinction, but ”overkill” explores the idea that early humans migrated onto the continent and then hunted the mammoths and other megafauna to extinction. The overkill hypothesis was first proposed by anthropologist Paul Martin in 1973 [8]. Evidence from radiocarbon dating shows that the …

Solar Thermal Decoupled Electrolysis: Reaction Mechanism Of Electrochemical Oxidation Of Coo/Co(Oh)2, William Prusinski

Chemistry Honors Papers

A modified water electrolysis process has been developed to produce H2. The electrolysis cell oxidizes CoO to CoOOH and Co3O4 at the anode to decrease the amount of electric work needed to reduce water to H2. The reaction mechanism through which CoO becomes oxidized was investigated, and it was observed that the electron transfer occurred through both a species present in solution and a species adsorbed to the electrode surface. A preliminary mathematical model was established based only on the electron transfer to species in solution, and several kinetic parameters of the reaction were calculated. The average value of each …
