MULTI-COLLECTOR CONFIGURATION CONSIDERATIONS AND SUBSTRATE RELATIVE SENSITIVITY FACTOR EFFECTS FOR AGE-DATING MEASUREMENTS OF PARTICLES BY LARGE GEOMETRY SECONDARY ION MASS SPECTROMETRY

October 1, 2021
Author(s)
Todd Williamson, David S. Simons, John D. Fassett
Chronometry (a.k.a age-dating, AD) of materials by bulk mass spectrometric methods is a well-established technique based on analysis protocols that have been used in geological fields and by the non-proliferation communities for many years. Recently, it

Author(s)
James S. Sims, Maria Ruiz, Bholanath Padhy
This review presents a survey of the most important achievements in atomic and molecular calculations obtained with the Hylleraas-configuration interaction method (Hy-CI) and its extension the exponentially correlated Hylleraas-configuration interaction

Quantitative Craniofacial Analysis and Generation of Human Induced Pluripotent Stem Cells for Muenke Syndrome: A Case Report

September 22, 2021
Author(s)
Fahad Kidwai, Byron Mui, Konstantinia Almpani, Priyam Jani, Cyrus Keyvanfar, Kulsum Iqbal, Sriram Paravastu, Deepika Arora, Pamela Orzechowski, Randall Merling, Barbara Mallon, Jeremiah Woodcock, Vamsee Myneni, Moaz Ahmad, Paul Kruszka, Maximilian Muenke, Pamela Robey, Janice Lee
In this case report, we focus on Muenke syndrome (MS), a disease caused by the p.Pro250Arg variant in fibroblast growth factor receptor 3 (FGFR3) and characterized by uni- or bilateral coronal suture synostosis, macrocephaly without craniosynostosis

Effect of Chlorine and Chromium on Sulfur Solubility in Low-Activity Waste Glass

September 21, 2021
Author(s)
Tongan Jin, Eden Rivers, Dongsang Kim, Timothy Droubay, Evan Jahrman, Derek Mar, Brigitte Weese, Gerald Seidler, Albert Kruger
According to an empirical sulfur solubility model developed from over 200 simulated low-activity waste (LAW) glasses, chlorine and chromium show strong effects on lowering sulfur solubility in glass. This work investigates the saturation concentrations of

Origin of enhanced water oxidation activity in an iridium single atom anchored on NiFe oxyhydroxide catalyst

August 31, 2021
Author(s)
Xueli Zheng, Jing Tang, Allesandro Gallo, Jose A. Garrido Torres, Xiaoyun Yu, Peter Ercius, Haiyan Mao, Emily Been, Constantine J. Athanitis, Sirine C. Fakra, Chengyu Song, Ryan Davis, Jeffrey A. Reimer, John Vinson, Michal Bajdich, Yi Cui
The efficiency of the synthesis of renewable fuels and feedstocks from electrical sources is limited, at present, by the sluggish water oxidation reaction. Single-atom catalysts (SACs) with a controllable coordination environment and exceptional atom

Naturally occurring organobromine compounds (OBCs) including polybrominated dibenzo-p-dioxins in the marine sponge Hyrtios proteus from The Bahamas

August 25, 2021
