The validity of estimating the solid phase diffusion coefficient, Ds, of a lithium intercalation electrode from impedance measurement by a modified electrochemical impedance spectroscopy (EIS) method is studied. A macroscopic porous electrode model and concentrated electrolyte theory are used to simulate the synthetic impedance data. The modified EIS method is applied for estimating Ds. The influence of parameters such as the exchange current density, radius of active material particle, solid phase conductivity, porosity, volume fraction of inert material, and thickness of the porous carbon intercalation electrode, the solution phase diffusion coefficient, and transference number, on the …

Increasing Proton Exchange Membrane Fuel Cell Catalyst Effectiveness Through Sputter Deposition, Andrew T. Haug, Ralph E. White, John W. Weidner, Wayne Huang, Steven Shi, Timothy Stoner, Narender Rana
Faculty Publications
Sputter deposition has been investigated as a tool for manufacturing proton-exchange membrane fuel cell (PEMFC) electrodes with improved performance and catalyst utilization vs. ink-based electrodes. Sputter-depositing a single layer of Pt on the gas diffusion layer provided better performance (0.28 A/cm2 at 0.6 V) than sputtering the Pt directly onto a Nafion membrane (0.065 A/cm2 at 0.6 V) and equaled the performance of the baseline for an equivalent Pt loading. Sputter-depositing alternating layers of Pt and Nafion-carbon ink (NCI) onto the membrane did not increase the performance over the baseline as measured in amperes per centimeter squared due …
Ability Of Native American Tribes To Waive Their Tribal Sovereign Immunity In Clear And Unequivocal Contracts To Arbitrate - C&(And)L Enterprises, Inc. V. Citizen Band Potawatomie Tribe Of Oklahoma, The, Emily J. Huitsing
Journal of Dispute Resolution
Native American tribes enjoy immunity from suits on contracts made on or off a reservation.2 A tribe is subject to suit only if it has clearly waived its immunity or Congress has expressly authorized the suit.' Tribal immunity was given to the tribes on the principle that tribes are sovereigns or quasi sovereigns enjoying immunity from judicial attack absent their consent.4 The purpose of tribal sovereignty, according to the Supreme Court, is to promote tribal economic development and self-sufficiency.5 Though the Court has expressed its dissatisfaction with the doctrine in light of increased tribal economic self-sufficiency through successful business ventures, …
Simulating Shape Changes During Electrodeposition: Primary And Secondary Current Distribution, Venkat R. Subramanian, Ralph E. White
Simulating Shape Changes During Electrodeposition: Primary And Secondary Current Distribution, Venkat R. Subramanian, Ralph E. White
Faculty Publications
A technique based on the analytical method of lines is presented for predicting shape changes during electrodeposition. The technique is presented for both primary and secondary current distributions. The method presented does not require iterations for nonlinear Butler-Volmer boundary conditions or changing electrode shapes. The technique is based on a semianalytical method developed earlier for predicting current distributions in electrochemical cells. This technique is attractive because it provides a symbolic solution for the Laplace equation, and hence requires less computation time to perform case studies.
Electrochemical Filtering Of Co From Fuel-Cell Reformate, Balasubramanian Lakshmanan, Wayne Huang, John W. Weidner
Electrochemical Filtering Of Co From Fuel-Cell Reformate, Balasubramanian Lakshmanan, Wayne Huang, John W. Weidner
Faculty Publications
A proton exchange membrane fuel cell was used as a flow reactor for continuous preferential oxidation of CO over H2 from 1.0% CO in H2 under pulse-potential control. By varying the pulse profile ~e.g., on-time, off-time, pulse potential! the CO and H2 oxidation currents were varied independently. The improvement in faradaic selectivity between CO and H2 oxidation results from the promotion of CO adsorption during the off ~i.e., open-circuit! portion of the pulse. Therefore, during the on portion CO oxidation was preferred while the surface was covered with CO.

Anodic Behavior Of Ti In Koh Solutions: Ellipsometric And Micro-Raman Spectroscopy Studies, A. Prusi, Lj. Arsov, Bala Haran, Branko N. Popov
Faculty Publications
Anodic formation of oxide films on titanium surfaces, in various concentrations of aqueous KOH solutions, have been studied using ellipsometry and micro-Raman spectroscopy. By in situ ellipsometric measurements the coefficient of film thickness growth and indexes of refraction of anodic oxide films have been determined. The voltage at which the oxide film breaks down is strongly dependent on the KOH concentration. Further, the solution concentration strongly influences the potential at which the oxide film is transformed from the amorphous state to crystalline form. Using micro-Raman spectroscopy four crystalline forms of titanium oxides, namely, anatase, brookite, corundum, and rutile, have been …

Modeling The Effects Of Electrode Composition And Pore Structure On The Performance Of Electrochemical Capacitors, Changqing Lin, Branko N. Popov, Harry J. Ploehn
Faculty Publications
This work presents a mathematical model for charge/discharge of electrochemical capacitors that explicitly accounts for particle-packing effects in a composite electrochemical capacitor consisting of hydrous RuO2 nanoparticles dispersed within porous activated carbon. The model is also used to investigate the effect of nonuniform distributions of salt in the electrolyte phase of the electrode in the context of dilute solution theory. We use the model to compare the performance of capacitors with electrodes made from different activated carbons and to investigate the effects of varying carbon content and discharge current density. Even at low discharge current density, concentration polarization in …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Development of sustainable agricultural management systems will depend, in part, on the ability to better use renewable resources, such as animal manure, and to synchronize the levels of soil available N with crop plant needs during the growing season. This study was conducted at the US Meat Animal Research Center in the central USA to determine whether differences in electromagnetic (EM) soil conductivity and available N levels over a growing season can be linked to feedlot manure/compost application and use of a green winter cover crop. A series of soil conductivity maps of a research cornfield were generated using global …

Purification Of The Hmg1 Protein And Investigation Of Its Interactions With Diepoxide Cross-Linked Dna, Gayle Pageau
Purification Of The Hmg1 Protein And Investigation Of Its Interactions With Diepoxide Cross-Linked Dna, Gayle Pageau
Honors Theses
HMG1 is a nonhistone chromosomal protein that binds preferentially to some types of globally modified DNA. HMG1 has been implicated in the cellular response to the anti-cancer agent cisplatin, functioning to block excision repair of specific distorted platinated DNA lesions and resulting in enhanced cytotoxicity. We have investigated whether other DNA-binding agents also produce lesions that are recognized by HMG1. Specifically, we used polyacrylamide gel shift assays to monitor the potential HMG1 binding of diepoxybutane interstrand cross-links, which have been suggested to induce DNA bending. We isolated the native protein from chicken erythrocytes and expressed engineered HMG domain proteins in …

Particle Formation By Rapid Expansion Of Supercritical Solutions, Chandra S. Vemavarapu
Open Access Dissertations
This body of work is intended to serve as a proof of concept for the application of supramolecular chemistry in drug development. More specifically, this work is designed to evaluate crystal doping by recrystallization from supercritical media. The rapid nucleation and growth implicit to supercritical fluid based crystallizations were tested in doping drug crystals with structurally related impurities. The ultimate motive was to tailor the physicochemical properties of active pharmaceutical ingredients (APT) through crystal doping. This, in tum provides the ability to tie functionality to APl's at early stages of drug discovery and synthesis. Methods. The rapid expansion of supercritical …
