Structural Study of an Unusual Cubic Pyrochlore Bi 1.5 Zn o.92 Nb 1.5 O 6.92

October 1, 2002
Author(s)
Igor Levin, T G. Amos, J Nino, Terrell A. Vanderah, C A. Randall, M T. Lanagan
Single-phase pyrochlore specimens of Bi 1.5Zn 0.92Nb 1.5O 6.92 were studied using combined electron, X-ray and neutron powder diffraction techniques. Rietveld refinements using neutron powder diffraction data confirmed an average pyrochlore structure A 2B

Sorptivity-Based Service Life Predictions for Concrete Pavements

September 1, 2001
Author(s)
Dale P. Bentz, M A. Ehlen, Chiara F. Ferraris, Edward J. Garboczi
The degradation of concrete pavements is often controlled by the transport of a deleterious species (chloride or sulfate ions, or water in the case of freeze/thaw) into the concrete. With this in mind, a three-year research project, funded by the Federal

Electron Collision Data for Plasma-Processing Gases

October 1, 2000
Author(s)
Loucas G. Christophorou, James K. Olthoff
Low-temperature plasma applications require detailed understanding of the physical and chemical processes occurring in the plasmas themselves. For instance, as the push for smaller feature sizes and higher quality devices in the semiconductor industry has

Barium Hollandite-Type Compounds Ba x Fe 2x Ti 8-2x O 16 with x= 1.143 and 1.333

February 23, 1999
Author(s)
J. M. Loezos, Terrell A. Vanderah, A R. Drews
Experimental X-ray powder diffraction patterns and refined unit cell parameters for two barium hollandite-type compounds. Ba xFe 2xTi 8-2xO 16, with x = 1.143 and 1.333, are reported here. Compared to the tetragonal parent structure, both compounds exhibit

New analysis of Fe VII

February 5, 2022
Author(s)
Alexander Kramida, A.N. Ryabtsev, Peter R. Young
New spectrograms of multiply ionized iron have been recorded and analyzed, targeting the Fe VII spectrum. As a result, several previously unknown spectral lines and energy levels have been identified in this spectrum. These new data have been analyzed

Probing Intrinsic Magnetization Dynamics of the Y3Fe5O12/Bi2Te3 Interface at Low Temperature

July 23, 2024
Author(s)
A. R. Will-Cole, Valeria Lauter, Alexander Grutter, Carsten Dubs, David Lidsky, Morris Lindner, Timmy Reimann, Nirjhar Bhattacharjee, Tzu-Ming Lu, Peter Sharma, Nichole Valdez, Charles Pearce, Todd Monson, Matthew Matzelle, Arun Bansil, Don Heiman, Nian Sun
Topological insulator–magnetic insulator (TI–MI) heterostructures hold significant promise in the field of spintronics, offering the potential for manipulating magnetization through topological surface state–enabled spin-orbit torque. However, many TI–MI

Lattice vibrations and the energy landscape of the isoelectronic semiconductor series CuBr, ZnSe, GaAs, and Ge: The special case of CuBr and its d-level chemistry

November 9, 2023
Author(s)
Joseph Woicik, Eric J. Cockayne, Eric L. Shirley, Igor Levin, Conan Weiland, Bruce D. Ravel, A. M. Milinda Abeykoon
We have examined the lattice vibrations and the energy landscape of the isoelectronic diamond and zincblende semiconductor series CuBr, ZnSe, GaAs, and Ge. Vibrations are found to be an increasing function of ionicity, with the cation sublattice always

The Single Residue K12 Governs the Exceptional Voltage Sensitivity of Mitochondrial Voltage-Dependent Anion Channel Gating

August 17, 2022
Author(s)
Van Ngo, Maria Queralt-Martin, Farha Khan, Lucie Bergdoll, Jeff Abramson, Sergey M. Bezrukov, Tatiana Rostovtseva, David Hoogerheide, Sergei Noskov
The voltage-dependent anion channel (VDAC) is a β-barrel channel of the mitochondrial outer membrane (MOM) that passively transports ions, metabolites, polypeptides, and single-stranded DNA. VDAC responds to a transmembrane potential by transitioning to a
