Magnetic Ordering in the Ising Antiferromagnetic Pyrochlore Nd 2 ScNbO 7

May 14, 2021
Author(s)
C. Mauws, N. Hiebert, M. Rutherford, H. D. Zhou, Q. Huang, M. B. Stone, Nicholas Butch, Y. Su, E. S. Choi, Z. Yamani, C. R. Wiebe
The question of structural disorder and its effects on magnetism is relevant to a number of spin liquid candidate materials. Although commonly thought of as a route to spin glass behavior, here we describe a system in which the structural disorder destroys

Targeted enrichment of 28Si thin films for quantum computing

March 9, 2020

Enriching 28Si beyond 99.9998 % for semiconductor quantum computing

August 5, 2014
Author(s)
Kevin J. Dwyer, Joshua M. Pomeroy, David S. Simons, June W. Lau, Kristen L. Steffens
Using a laboratory-scale apparatus, we enrich 28Si and produce material with 40 times less residual 29Si than previously reported. Starting from natural abundance silane gas, we offer an alternative to industrial gas centrifuges for providing materials

Adaptive Peak Fitting for Isotope Analysis via Atom Probe Mass Spectrometry

July 30, 2021
Author(s)
Frederick Meisenkothen, Daniel Samarov, Mark McLean, Irina Kalish, Eric B. Steel
… Since the peak forms can vary significantly between ion species and between data sets, no model peak form can be … method for assigning ions in the spectrum to specific ion species, as an alternative approach to the traditional ion ranging strategies. The goal is to produce an accurate, …

Ionization and appearance potentials in organic chemistry. 3. Determination of the difference between the enthalpies of formation of cis- and trans-isomers of bicyclo[4.3.0]- nonane and bicyclo[4.4.0]decane Using Appearance Potentials

Energy Levels and Spectral Lines of Ne VII

February 8, 2006
Author(s)
Alexander Kramida, M-C Buchet-Poulizac
All experimental data on Ne VII, including previously unpublished beam-foil spectroscopy data, have been compiled and critically evaluated. More than a hundred spectral lines have been newly identified. For 40 transitions, the previous identifications have

'Supercritical Water' Density Effects on the Rate of Isopropanol Dehydration

January 1, 2001
Author(s)
V I. Anikeev, Jeffrey A. Manion, A Ermakova
A new experimental procedure for studying the kinetics and thermodynamics of chemical reactions in supercritical fluids-solvents was suggested. The kinetics and mechanism of the dehydration of 2-propanol in supercritical water in a closed reactor were
