Thermoelectric and Structural Characterization of Ba2Ho(Cu3-xCox)O6+y

June 13, 2009
Author(s)
Winnie K. Wong-Ng, Z Yang, Y F. Hu, Qingzhen Huang, Nathan Lowhorn, Makoto Otani, James A. Kaduk, Martin L. Green, Q Li
The search for thermoelectric materials for power generation and for solid-state cooling have led to the increased interest of layered cobalt-containing oxides because of their thermal stability at high temperature and their desirable thermoelectric

Structural and magnetic phase diagram of CeFeAsO1- xFx and its relation to high-temperature superconductivity

October 26, 2008
Author(s)
Jun Zhao, Qingzhen Huang, Clarnia dela Cruz, Shiliang Li, Jeffrey Lynn, Ying Chen, Mark Green, G. F. Chen, Z. C. Li, J. L. Luo, N. L. Wang, Pengcheng Dai
Recently, high-transition-temperature (high-Tc) superconductivity was discovered in the iron pnictide RFeAsO1−xFx (R, rare-earth metal) family of materials. We use neutron scattering to study the structural and magnetic phase transitions in CeFeAsO1−xFx as

A Regional Comparison of Calibration Results for Type K Thermocouple Wire From 100 C to 1100 C

June 5, 2008
Author(s)
K Garrity, Dean C. Ripple, M Araya, C R. Cabrera, L Cordova Murillo, M E. de Vanegas, D J. Gee, Edwin Guillen, S Martinez-Martinez, Edgar Mendez-Lango, L Mussio, S G. Petkovic, K N. Quelhas, G Rangugni, O Robatto, E Von Borrries Rocha
Under the auspices of the Inter-american Metrology System (SIM), the National Institute of Standards and Technology (NIST) initiated a regional comparison for type K thermocouples from 100 deg. C to 1100 deg. C, with 11 participating countries. Each

Selectable Resistance-Area Product by Dilute Highly Charged Ion Irradiation

August 13, 2007
Author(s)
Joshua M. Pomeroy, Holger Grube, A C. Perrella, John D. Gillaspy
In order to provide high performance read heads for future hard drive densities, considerable effort worldwide has been invested in developing techniques for producing low resistance area product (RA) magnetic tunnel junction sensors. In this letter, we

Further Studies of Cup-Burner Flame Extinguishment.

May 16, 2006
Author(s)
F Takahashi, Gregory T. Linteris, Vishwanath R. Katta
The structure and extinguishment of heptane-air co-flow diffusion flames formed on a cup burner in normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO2) was introduced gradually into a coflowing

Universal Gradient Substrates for Click Biofunctionalization

February 22, 2006
Author(s)
Nathan D. Gallant, Kristopher Lavery, Eric J. Amis, Matthew Becker
In order to facilitate research on biomimetic and tissue engineered medical products we have developed a novel and versatile method for fabricating continuously variable concentration gradients of surface conjugated biomolecules. This technology utilizes

Towards reproducible SCM Image Interpretation

February 1, 2004
Author(s)
Joseph Kopanski, Jay F. Marchiando, Brian G. Rennex, David S. Simons, R P. Chaudhury
… to SCM image variability include: poor sample surface and oxide quality, excess carrier generation from stray light, …

Premixed Flame Inhibition by Manganese and Tin Compounds

April 24, 2001
Author(s)
Gregory T. Linteris, Vadim D. Knyazev, Valeri I. Babushok
Flame inhibition data exist for a few metallic compounds (Fe(CO)5, Pb(C2H5)4, CrO2Cl2) which show them to be one or two orders of magnitude more effective than halon 1301 at reducing the burning velocity of premixed methane-air flames. Little burning

First-Order Phase Transition versus Spin-State Quantum-Critical Scenarios in Strain-Tuned Epitaxial Cobaltite Thin Films

February 14, 2024
Author(s)
John Dewey, Vipul Chaturvedi, Tatiana Webb, Prachi Sharma, William Postiglione, P. Quarterman, Purnima Balakrishnan, Brian Kirby, Lucca Figari, Caroline Korostynski, Andrew Jacobson, Turan Birol, Rafael Fernandes, Abhay Pasupathy, Chris Leighton
Pr-containing perovskite cobaltites exhibit unusual valence transitions, coupled to coincident structural, spin-state, and metal-insulator transitions. Heteroepitaxial strain was recently used to control these phenomena in the model (Pr1−yYy )1−xCaxCoO3−δ
