Tungsten L Transition Line Shapes and Energy Shifts Resulting from Ionization in Warm Dense Matter

April 18, 2013
Author(s)
Lawrence T. Hudson, John F. Seely, Bruce V. Weber, D. G. Phipps, Nino R. Pereira, D Mosher, K. Slabkowska, M. Polasik, J Rzadkiewicz, S Hansen, Uri Feldman, Joseph W. Schumer
High resolution spectra of the W L transitions in the energy range 8 keV to 12 keV from warm dense plasmas generated by the Naval Research Laboratory’s Gamble III pulsed power machine were recorded by a transmission-crystal x-ray spectrometer with ± 2 eV

In situ Formation of Silver Nanoparticles in Photocrosslinking Polymers

February 2, 2011

Yajun Cheng, Diana N. Zeiger, John A. Howarter, Xinran Zhang, Nancy Lin, Joseph M. Antonucci, Sheng Lin-Gibson
… free radical polymerization with in situ silver ion reduction. A polymerizable methacrylate bearing a … infrared spectroscopy (FTIR) revealed that the silver ion reduction had no significant effect on the degree of …

Magnetic Order and Instability in Newly Synthesized CoSeAs Marcasite

May 13, 2020
Author(s)
Yiyao Chen, G. Yumnam, A. Dahal, Jose Rodriguez Rivera, Guangyong Xu, T. Heitmann, D. K. Singh
Marcasite class of compounds provide facile platform to explore novel phenomena of fundamental and technological importance, such as unconventional superconductivity or high performance electrocatalyst. We report the synthesis and experimental

Structural Calcium (Trypsin, Subtilisin)

February 19, 2017
Author(s)
G L. Gilliland, A Teplyakov
There are about 40 families of serine proteases defined by amino acid sequence similarities that can be further grouped into 7 clans on the basis of their tertiary structure and the order of the catalytic triad. 1 Members of clans SA and SB are

Electronic Nature of the Lock-in Magnetic Transition in CeXAl 4 Si 2

April 25, 2016
Author(s)
J. Gunasekera, Leland Harriger, A. Dahal, A. Maurya, T.W. Heitmann, Steven M.T. Disseler, A. Thamizhavel, S. Dhar, D. J. Singh, D. K. Singh
We have investigated the underlying magnetism in newly discovered single crystal Kondo lattices CeXAl 4Si 2, where X = Rh, Ir. We show that the compound undergoes an incommensurate-to- commensurate magnetic transition at Tc = 9.19 K (10.75 K in Ir). The

Technical Report of Range-BASF Program

… that powers electric vehicles other than the existing Li-ion battery. With the use of a rare-earth free metal hydride …

Quasilocal Critical Nature of Cooperative Paramagnetic Fluctuations in CaRuO 3 Metal

June 8, 2015
Author(s)
J. Gunasekera, Leland Harriger, T. Heitmann, A. Dahal, H. Knoll, D. K. Singh
We report new observation of cooperative paramagnetic fluctuations of Ru 4+ spins that coexist with the non-Fermi liquid state in CaRuO 3 perovskite below T22 K. Detailed electrical, magnetic and neutron scattering measurements reveal that the Ru R+ ions

Optically pumped semiconductor lasers for atomic and molecular physics

February 7, 2015
Author(s)
Dietrich G. Leibfried, Shaun Burd, Andrew C. Wilson, David J. Wineland
Experiments in atomic, molecular and optical (AMO) physics rely on lasers at many different wavelengths and with varying requirements on spectral linewidth, power and intensity stability. Optically pumped semiconductor lasers (OPSLs), when combined with

Resonance Strength in 22Ne(p,gamma)23Na from Depth Profiling in Aluminum

April 30, 2010
Author(s)
R Longland, C. Iliadis, J. Cesaratto, A E. Champagne, S Daigle, J.R. Newton, Ryan P. Fitzgerald
The novel method for extracting absolute resonance strengths has been investigated. By implanting 22Ne ions into a thick aluminum backing, and simultaneously measuring the 22Ne + p and 27Al+p reactions, the strength of the Elab,r = 479 keV resonance in
