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

June 1, 1980
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin
The first adiabatic potentials of the ionization of cis and trans iosmers with respect to the linkage of the rings of bicyclo[4.3.0]nonane and bicyclo[4.4.0]decane are practically identical. for the stereoisomers of these two series have been measured. The

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All experimental data on Ne VII, including previously unpublished beam-foil spectroscopy data, have been compiled and critically evaluated.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

Wavelength standards for optical communications

… that utilize the absorption lines of acetylene and hydrogen cyanide in the 1500 nm region. Two higher accuracy …

Polymer Mobility Near the Polymer/Solid Interface

May 6, 1999
Author(s)
Eric K. Lin, Wen-Li Wu, Sushil K. Satija, R Kolb
Neutron reflectometry is used to measure polymer mobility near an attractive solid surface over distances less than the bulk polymer radius of gyration, R g. Effective diffusion coefficients, D eff, are determined from the rates of interdiffusion between

Transient Phenoxyl Radicals: Formation and Properties in Aqueous Solutions

October 12, 2021
Author(s)
S Steenken, Pedatsur Neta
This chapter discusses the various methods of formation of phenoxyl radicals (oxidation of phenols by metal ions, by free radicals and radical cations, reaction of phenols with hydroxyl radicals, autoxidation of phenols, etc.) and the properties of

Quantum Dense Coding with Atomic Qubits

January 1, 2004
Author(s)
T Schaetz, Murray D. Barrett, Dietrich G. Leibfried, J Chiaverini, Joseph W. Britton, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
We report the implementation of quantum dense coding on individual atomic qubits with the use of two trapped 9Be+ ions. The protocol is implemented with a complete Bell measurement that distinguishes the four operations used to encode two bits of classical
