Study Of Sn-Coated Graphite As Anode Material For Secondary Lithium-Ion Batteries, Basker Veeraraghavan, Anand Durairajan, Bala Haran, Branko N. Popov, Ronald Guidotti

Faculty Publications

Tin-graphite composites have been developed as an alternate anode material for Li-ion batteries using an autocatalytic deposition technique. The specific discharge capacity, coulombic efficiency, rate capability behavior, and cycle life of Sn-C composites has been studied using a variety of electrochemical methods. The amount of tin loading and the heating temperature have a significant effect on the composite performance. The synthesis conditions and Sn loading on graphite have been optimized to obtain the maximum reversible capacity for the composite electrode. Heating the composite converts it from amorphous to crystalline form. Apart from higher capacity, Sn-graphite composites possesses higher coulombic efficiency, …

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 …

Thermal Death Kinetics And Heatingrate Effects For Fifth-Instar Cydia Pomonella (L.) (Lepidoptera: Tortricidae), S. Wang, J. N. Ikediala, J. Tang, J. D. Hansen Jan 2002

Thermal Death Kinetics And Heatingrate Effects For Fifth-Instar Cydia Pomonella (L.) (Lepidoptera: Tortricidae), S. Wang, J. N. Ikediala, J. Tang, J. D. Hansen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Thermal death kinetic parameters of fifth-instar codlingmoths (Cydia pomonella (L.)) and the effect of three heating rates (1°Cmin-1, 10°Cmin-1, and 18°Cmin-1) on larval mortality were determined by a heatingblock system. The insects were heated to four temperatures (46°C, 48°C, 50°C, and 52°C) held for predetermined periods followed by 24 h storage at 4°C before mortality evaluation. Thermal death kinetics for fifth-instar codlingmoths followed a 0.5th order of kinetic reaction. Minimum time required to achieve 100% mortality of a given population decreased with temperature in a semi-logarithmic manner. No larval survival was observed in …

Purification Of The Hmg1 Protein And Investigation Of Its Interactions With Diepoxide Cross-Linked Dna, Gayle Pageau Jan 2002

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 Jan 2002

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 …
