Infrared Spectra of Small Molecular Ions Trapped in Solid Neon

October 3, 2010
Author(s)
Marilyn E. Jacox
The infrared spectrum of a molecular ion provides a unique signature for that species, gives information on its structure, and is amenable to remote sensing. It also serves as a comparison standard for refining ab initio calculations. Experiments in this

Author(s)
Douglas Thomas, Anand M. Kandaswamy
This report provides an overview of the US manufacturing industry. There are three aspects of U.S. manufacturing that are considered: (1) how the US industry compares to other countries, (2) the trends in the domestic industry, and (3) the industry trends

Determination of high-molecular weight polycyclic aromatic hydrocarbons in high performance liquid chromatography fractions of coal tar standard reference material 1597a via solid-phase nanoextraction and laser-excited time-resolved Shpolskii spectr

November 10, 2015
Author(s)
Walter B. Wilson, Bassam Alfarhani, Cristina Bisson, Stephen A. Wise, Andres Campiglia
This article presents an alternative approach for the analysis of high molecular weight – polycyclic aromatic hydrocarbons (HMW-PAHs) with molecular mass 302 Da in complex environmental samples. This is not a trivial task due to the large number of

Kinetic Study of the Reactions of CF 3 O 2 Radicals with Cl and NO

October 1, 1999
Author(s)
F Louis, Donald R. Burgess Jr., M Rayez, J P. Sawerysyn
Kinetic studies of the reactions CF 3O 2 + Cl and CF 3O 2 + NO were performed at room temperature in the gas phase using the discharge flow/mass spectrometric technique (DF/MS). The reactions were investigated under pseudo-first-order conditions with Cl or

Author(s)
Jihun Park, Jarryd Horn, Dylan Kirsch, Rohit Pant, Hyeok Yoon, Sungha Baek, suchismita sarker, Apurva Mehta, Xiaohang Zhang, Seunghun Lee, Richard Greene, Johnpierre Paglione, Ichrio Takeuchi
The Bi–Ni binary system has been of interest due to possible unconventional superconductivity aroused therein, such as time-reversal symmetry breaking in Bi/Ni bilayers or the coexistence of superconductivity and ferromagnetism in Bi3Ni crystals. While Ni

Accelerator-Based Production of Scandium Radioisotopes for Applications in Prostate Cancer: Toward Building a Pipeline for Rapid Development of Novel Theranostics

Rapid Vapor-Collection Method for Vapor Pressure Measurements of Low-Volatility Compounds

November 24, 2020
Author(s)
Jason Widegren, Tara Lovestead, Megan Harries, Cheryle Beuning, Bridger L. Johnston
Dynamic vapor microextraction (DVME) is a new method that enables rapid vapor pressure measurements on large molecules with state-of-the-art measurement uncertainty for vapor pressures near 1 Pa. Four key features of DVME that allow for the rapid
