Rapid Structural Mapping Of Ternary Metallic Alloy Systems Using The Combinatorial Approach And Cluster Analysis, C. J. Long, Jason R. Hattrick-Simpers, M. Murakami, R. C. Srivastava, I. Takeuchi, V. L. Karen, X. Li

Faculty Publications

We are developing a procedure for the quick identification of structural phases in thin film composition spread experiments which map large fractions of compositional phase diagrams of ternary metallic alloy systems. An in-house scanning x-ray microdiffractometer is used to obtain x-ray spectra from 273 different compositions on a single composition spread library. A cluster analysissoftware is then used to sort the spectra into groups in order to rapidly discover the distribution of phases on the ternary diagram. The most representative pattern of each group is then compared to a database of known structures to identify known phases. Using this method, …

Accidental Rights, James Gibson Jan 2007

Accidental Rights, James Gibson

Law Faculty Publications

Written for the Yale Law Journal's online Pocket Part, this is a much shorter and (I hope) more accessible iteration of my earlier paper, Risk Aversion and Rights Accretion in Intellectual Property Law, 116 Yale L.J. 882 (2007). It summarizes that paper's central point - i.e., that intellectual property entitlements are growing not just because of expansive court decisions and legislative enactments, but also because of seemingly sensible, risk-averse licensing decisions that inadvertently feed back into legal doctrine - and then explores how this phenomenon might apply to (and be manipulated by) enterprises such as Google Book Search.

Short-Time Transient Analysis Of Intercalation Of An Ion Into A Sphere, Sheba Devan, Ralph E. White Jan 2007

Short-Time Transient Analysis Of Intercalation Of An Ion Into A Sphere, Sheba Devan, Ralph E. White

Faculty Publications

A short-time transient analysis is presented for a sinusoidal input potential for a spherical particle. The objective of this work was to extract accurate values of the parameters associated with an intercalation into a spherical particle. These parameters are exchange current density, double-layer capacitance, and diffusion coefficient. The effects of these parameters on the response were examined using a sensitivity analysis, which indicated that optimum frequency values of the input perturbation exist for estimation of these parameters. A procedure is presented to obtain all these parameters using the short-time response. The results show that the short-time analysis is a useful …

Analytical Expression For The Impedance Response Of An Insertion Electrode Cell, Godfrey Sikha, Ralph E. White Jan 2007

Analytical Expression For The Impedance Response Of An Insertion Electrode Cell, Godfrey Sikha, Ralph E. White

Faculty Publications

An analytical expression for the impedance response of an insertion cathode/separator/foil anode cell sandwich is presented. The analytical expression includes the impedance contributions from interfacial kinetics, double-layer adsorption, and solution-phase and solid-phase diffusion processes. The validity of the analytical solution is ascertained by comparison with the numerical solution obtained for a LiCoO2 /polypropylene/lithium metal cell. The flexibility of the analytical solution is utilized to analyze various limiting conditions. An expression to estimate solid-phase diffusion coefficient of insertion species in a porous electrode influenced by the solution-phase diffusion process is also derived

Simulation Of Polarization Curves For Oxygen Reduction Reaction In 0.5 M H2So4 At A Rotating Ring Disk Electrode, Qingbo Dong, Shriram Santhanagopalan, Ralph E. White Jan 2007

Simulation Of Polarization Curves For Oxygen Reduction Reaction In 0.5 M H2So4 At A Rotating Ring Disk Electrode, Qingbo Dong, Shriram Santhanagopalan, Ralph E. White

Faculty Publications

A cylindrical two-dimensional model based on the Nernst–Planck equations, the Navier–Stokes equation, and the continuity equation is used to simulate the oxygen reduction reaction in 0.5MH2SO4 at a rotating ring disk electrode. Concentration distributions and a potential profile are obtained as a function of the axial and radial distances from the center of the electrode surface. Polarization curves are simulated to interpret experimental results by studying various reaction mechanisms, i.e., the four-electron-transfer reduction of oxygen, the two-electron-transfer reduction of oxygen, a combination of the above two reactions, mechanisms with reduction of peroxide to water, and/or the heterogeneous …

Moving Boundary Model For The Discharge Of A Licoo2 Electrode, Qi Zhang, Ralph E. White Jan 2007

Moving Boundary Model For The Discharge Of A Licoo2 Electrode, Qi Zhang, Ralph E. White

Faculty Publications

A moving boundary model in a spherical LiCoO2 particle is presented to account for the diffusion controlled phase transition in LiCoO2 solid particles, and this model is incorporated into a porous electrode model for the LiCoO2 electrode. The simulation results agree well with the experimental data of a LiCoO2 electrode. A study of the flux distribution in the porous electrode shows that the phase transition phenomenon in the LiCoO2particles has a significant effect on the flux distribution by changing the solid phase diffusion resistance in the particles.

Parameter Estimation And Model Discrimination For A Lithium-Ion Cell, Shriram Santhanagopalan, Qingzhi Guo, Ralph E. White Jan 2007

Parameter Estimation And Model Discrimination For A Lithium-Ion Cell, Shriram Santhanagopalan, Qingzhi Guo, Ralph E. White

Faculty Publications

Two different models were used to obtain transport and kinetic parameters using nonlinear regression from experimental charge/discharge curves of a lithium-ion cell measured at 35°C under four rates, C/5, C/2, 1C, and 2C, where the C rate is 1.656A . The Levenberg-Marquardt method was used to estimate parameters in the models such as the diffusion of lithium ions in the positive electrode. A confidence interval for each parameter was also presented. The parameter values lie within their confidence intervals. The use of statistical weights to correct for the scatter in experimental data as well as to treat one set of …

Effect Of Water On The Electrochemical Oxidation Of Gas-Phase So2 In A Pem Electrolyzer For H2 Production, John Staser, Ramaraja P. Ramasamy, Premkumar Sivasubramanian, John W. Weidner Jan 2007

Effect Of Water On The Electrochemical Oxidation Of Gas-Phase So2 In A Pem Electrolyzer For H2 Production, John Staser, Ramaraja P. Ramasamy, Premkumar Sivasubramanian, John W. Weidner

Faculty Publications

Water plays a critical role in producing hydrogen from the electrochemical oxidation of SO2 in a proton exchange membrane (PEM) electrolyzer. Not only is water needed to keep the membrane hydrated, but it is also a reactant. One way to supply water is to dissolve SO2 in sulfuric acid and feed that liquid to the anode, but this process results in significant diffusion resistance for the SO2. Alternatively, we have developed a process where SO2 is fed as a gas to the anode compartment and reacts with water crossing the membrane to produce sulfuric acid. There was concern that the …

Effect Of Diphenyl Siloxane On The Catalytic Activity Of Pt On Carbon, Vijay A. Sethuraman, John W. Weidner, Lesia V V. Protsailo Jan 2007

Effect Of Diphenyl Siloxane On The Catalytic Activity Of Pt On Carbon, Vijay A. Sethuraman, John W. Weidner, Lesia V V. Protsailo

Faculty Publications

The effect of silicone on the catalytic activity of Pt for oxygen reduction and hydrogen adsorption was studied using diphenyl siloxane as a source compound at a rotating disk electrode (RDE). Diphenyl siloxane did not affect the catalytic activity of Pt when it was injected into the electrolyte. However, it blocked the oxygen reduction reaction when it was premixed with the catalyst. Proton transport was not blocked in either case. We postulate that diphenyl siloxane induces hydrophobicity and causes local water starvation, thereby blocking oxygen transport. Hence, the slow leaching of silicone seals in a fuel cell could cause silicon …

Low-Temperature Synthesis Of A Ptru/Nb0.1ti0.9o2 Electrocatalyst For Methanol Oxidation, Brenda L. García, Roderick Fuentes, John W. Weidner Jan 2007

Low-Temperature Synthesis Of A Ptru/Nb0.1ti0.9o2 Electrocatalyst For Methanol Oxidation, Brenda L. García, Roderick Fuentes, John W. Weidner

Faculty Publications

Niobium was doped into anatase TiO2 support at 10 mol % (Nb0.1Ti0.9O2) using sol-gel chemistry. A PtRu/Nb0.1Ti0.9O2 catalyst was synthesized by LiBH4 reduction in tetrahydrofuran. The methanol electro-oxidation activity of the catalyst shows that this oxide support was electrically conductive. The current (A/gPt) was 6% higher on the PtRu/Nb0.1Ti0.9O2 catalyst compared to a commercial PtRu/C catalyst at 25°C. The electrochemically active surface area of the PtRu/C was 94% higher than PtRu/Nb0.1Ti0.9O2, thus the current per active site was 100% higher on PtRu/Nb0.1Ti0.9O2. A membrane electrode assembly with PtRu/Nb0.1Ti0.9O2 had 46% higher current (A/gPt) than an equivalent E-TEK membrane electrode assembly …

Exafs Characterization Of Dendrimer-Derived Pt/Γ-Al2o3, A. Siani, O. S. Alexeev, C. T. Williams, Harry J. Ploehn, M. D. Amiridis

Faculty Publications

The various steps involved in the preparation of a Pt/-Al2O3 material using hydroxyl-terminated generation four (G4OH) PAMAM dendrimers as templates were monitored by EXAFS. The results indicate that Cl ligands in the Pt precursors (H2PtCl6 and K2PtCl4) were partially replaced by aquo ligands upon hydrolysis to form [PtCl3(H2O)3]+ and [PtCl2(H2O)2] species. After interaction of such species with G4OH, Cl ligands from the first coordination shell of Pt were further replaced by nitrogen atoms from the dendrimer interior, …

Orchard Pollination In Capitol Reef National Park, Utah, Usa. Honey Bees Or Native Bees?, Vincent J. Tepedino, Terry L. Griswold, Diane Gail Alston, Trent R. Toler, Brosi A. Bradley Jan 2007

Orchard Pollination In Capitol Reef National Park, Utah, Usa. Honey Bees Or Native Bees?, Vincent J. Tepedino, Terry L. Griswold, Diane Gail Alston, Trent R. Toler, Brosi A. Bradley

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

Capitol Reef National Park in central Utah, USA surrounds 22 managed fruit orchards started over a century ago by Mormon pioneers. Honey bees are imported for pollination, although the area in which the Park is embedded has over 700 species of native bees, many of which are potential orchard pollinators. We studied the visitation of native bees to apple, pear, apricot, and sweet cherry over 2 years. Thirty species of bees visited the flowers but, except for pear flowers, most were uncommon compared to honey bees. Evidence that honey bees prevented native bees from foraging on orchard crop flowers was …

A Look At The Engineering Challenges Of The Usda Small Watershed Program, G. J. Hanson, L. Caldwell, M. Lobrecht, D. Mccook, S. L. Hunt, D. Temple

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

The Small Watershed Program, administered by the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service), originated in the 1940s and 1950s through the following statutes: the Flood Control Act of 1944, the pilot watershed program (1953-1954), and the Watershed Protection and Flood Prevention Act of 1954. The Small Watershed Program has been recognized by ASABE as one of the outstanding achievements of agricultural engineering in the 20th century in soil and water. With a $15 billion infrastructure investment, more than 11,000 flood-control dams were constructed, and thousands of acres of farms and ranches are protected by conservation practices. …

Effects Of Conservation Practices On Aquatic Habitats And Fauna, Scott Knight, Kathryn Boyer Jan 2007

Effects Of Conservation Practices On Aquatic Habitats And Fauna, Scott Knight, Kathryn Boyer

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

A major goal of both state and federal agricultural and environmental agencies in the United States is sustainable management of watersheds where agriculture is a dominant land use. Because watershed processes and conditions directly and indirectly affect soil, water, air, plants, animals, and humans, USDA NRCS encourages a watershed approach to management of agricultural operations in the United States. This requires a suite of approaches or practices that address natural resource concerns in uplands and stream corridors. Land clearing, leveling, draining, tilling, fertilizing, and harvesting together create prolonged perturbations manifested in the ecological and physical conditions of streams and rivers. …

Accidental Inversion During 3d Rotation With 2-Dof Input Devices, Derek Daniel Diaz Jan 2007

Accidental Inversion During 3d Rotation With 2-Dof Input Devices, Derek Daniel Diaz

Electronic Theses and Dissertations

This dissertation focuses on a human operator's ability to perform rotational control of a three-dimensional object using two-degrees of freedom (DOF) interface devices. Although input devices designed specifically for 3D interaction exist, devices traditionally used for two-dimensional user interaction, such as a mouse or joystick, have become ubiquitous to computer tasks. This research examines a particular human-computer interaction issue that arises from stimulus-response compatibility between three-dimensional stimuli spaces and 2-DOF response sets. The focal point of this research is a phenomenon referred to here as accidental inversion. Accidental inversions occur when an operator erroneously moves a three-dimensional object in a …

The Cercospora Nicotianae Gene Encoding Dual O-Methyltransferase And Fad-Dependent Monooxygenase Domains Mediates Cercosporin Toxin Biosynthesis, Katherine L. Dekkers, Bang-Jau You, Vivek S. Gowda, Hui-Ling Liao, Miin-Huey Lee, Huey-Jiunn Bau, Peter P. Ueng, Kuang-Ren Chung

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

Cercosporin, a photo-activated, non-host-selective phytotoxin produced by many species of the plant pathogenic fungus Cercospora, causes peroxidation of plant cell membranes by generating reactive oxygen species and is an important virulence determinant. Here we report a new gene, CTB3 that is involved in cercosporin biosynthesis in Cercospora nicotianae. CTB3 is adjacent to a previously identified CTB1 encoding a polyketide synthase which is also required for cercosporin production. CTB3 contains a putative O-methyltransferase domain in the N-terminus and a putative flavin adenine dinucleotide (FAD)-dependent monooxygenase domain in the C-terminus. The N-terminal amino acid sequence also is similar to …
