Atomic Transition Probabilities of SiliconA Critical Compilation

November 14, 2018
Author(s)
Daniel E. Kelleher, Larissa Podobedova
This compilation is the third in a series of updates to Atomic Transition Probabilities, Sodium through Calcium, published in 1969 by W. L. Wiese et al. Atomic transition probabilities have been critically evaluated and compiled for about 5800 spectral

Atomic Transition Probabilities of Sodium and Magnesium A Critical Compilation

November 14, 2018
Author(s)
Daniel E. Kelleher, Larissa Podobedova
This compilation is the first in a series of updates to Atomic Transition Probabilities, Sodium through Calcium, published in 19691. Atomic transition probabilities have been critically evaluated and compiled for about 12,000 spectral lines of sodium and

Binding Energies in Atomic Negative Ions: III

November 14, 2018
Author(s)
T Andersen, H K. Haugen, H Hotop
The article updates a fourteen-year-old review on this subject [J. Phys. Chem. Ref. Data 14, 731 (1985]. A survey of the electron affinity determinations for the elements up to Z = 94 is presented, and based upon these data, a set of recommended electron

Critically Evaluated Atomic Transition Probabilities for Sulfur S I Through S XV

November 14, 2018
Author(s)
Larissa Podobedova, Daniel E. Kelleher, Wolfgang L. Wiese
Atomic transition probabilities for about 6700 allowed and forbidden lines of S I through S XV are tabulated, based on a critical evaluation of recent literature sources. The transition probabilities were obtained mainly from recent sophisticated

Energy Levels and Observed Spectral Lines of Krypton, Kr I through Kr XXXVI

November 14, 2018
Author(s)
Edward B. Saloman
The energy levels and observed spectral lines of the krypton atom, in all stages of ionization for which experimental data are available, have been compiled. Sufficient data were found to generate level and line tables for Kr I through Kr X and Kr XVIII

Ignition of Japanese style tile roofing assemblies exposed to firebrands

November 14, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki
In a recent urban fire in Itoigawa-city, Niigata, Japan, structures were exposed to firebrands and it was reported roofing assemblies were ignited, which led to loss of entire structures. Roof tiles are fabricated using non-combustible materials yet the

IUPAC - NIST Solubility Data Series 68. Ammonium Phosphates

November 14, 2018
Author(s)
J Eysseltova, T P. Dirkse
The solubility of ammonium phosphate is reviewed. Many ammonium phosphates can be described in terms of the ternary system:NH 3-P 2O 5-H 2O. However, the system differs from systems like the sulfates and halates in that it has a marked tendency to form

Spectroscopic Data for Neutral Francium (Fr I)

November 14, 2018
Author(s)
Jean E. Sansonetti
Energy levels and hyperfine structure constants have been compiled for the sixteen longest-lived isotopes of francium (Z=87). Wavelengths with classifications and transition probabilities are also tabulated for 212Fr. In addition, the ionization energy is

Temperature Dependence of Physical-Chemical Properties of Selected Chemicals of Environmental Interest. II. Chlorobenzenes, Polychlorinated Biphenyls, Polychlorinated Dibenzo-p-dioxins and Dibenzofurans

November 14, 2018
Author(s)
W Y. Shiu, K C. Ma
ta are compiled and reviewed of the physical-chemical properties of chlorinated benzenes, biphenyls, dibenzo-p-dioxins, and dibenzofurans, which control air-water partitioning, namely vapor pressure, aqueous solubility, and Henry's law constant over the

Thermodynamic Properties of Ideal Gas Nitro and Nitrate Compounds

November 14, 2018
Author(s)
A Burcat
The detailed ideal gas thermodynamic properties of 29 organic nitro and nitrate compounds and two of their radicals are presented. Most of these compounds are high explosives: TNT, RDX, HMX, PETN, NPN, NG, while others serve as propellants or specialty

VIRTUAL EXPERIMENTAL INVESTIGATION FOR INDUSTRIAL ROBOTICS IN GAZEBO ENVIRONMENT

November 14, 2018
Author(s)
Murat Aksu, John L. Michaloski, Frederick M. Proctor
Measuring the agility performance of the industrial robots as they are performing in unstructured and dynamic environments is a thought-provoking research topic. This paper investigates the development of industrial robotic simulation algorithms for the

Analysis of Small Angle Neutron Scattering Spectra from Deformed Polymers with Spherical Harmonic Expansion Method and a Network Model

November 13, 2018
Author(s)
Zhi-Yuan Wang, Dejia Kong, Lincan Yang, Hongwei Ma, Fengmei Su, Kanae N. Ito, Yun Liu, Xuewu Wang, Zhe Wang
In this paper, we combine the recently proposed spherical harmonic expansion (SHE) method [Phys. Rev. X 2017, 7, 031003] with a modified network model to analyze the small-angle neutron scattering (SANS) spectra from deformed entangled polymers. Focusing

Effects of Nitrogen on the Interface Density of States Distribution in 4H-SiC Metal Oxide Semiconductor Field Effect Transistors: Super-hyperfine Interactions and Near Interface Silicon Vacancy Energy Levels

November 13, 2018
Author(s)
Mark Anders, Patrick M. Lenahan, Arthur H. Edwards, Peter A. Schultz, Renee M. Van Ginhoven
The performance of SiC-based metal-oxide-semiconductor field-effect transistors (MOSFETs) is greatly enhanced by a post oxidation anneal in NO. These anneals greatly improve effective channel mobilities and substantially decrease interface trap densities
