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

Hierarchically Patterned Elastomeric and Thermoplastic Polymer Films through Nanoimprinting and Ultraviolet Light Exposure

November 13, 2018
Author(s)
Jack F. Douglas, Ying Chen, Manish Kulkarni, Allan Marshall, Alamgir Karim, ZiLu Wang, Xiaoteng Wang, Abdullah Al-Enizi, Ahmed Elzatahry, Andrey V. Dobrynin
We develop a simple and generally applicable method to fabricate hierarchical interfacial patterns in elastomer and thermoplastic polymer films through a combination of nanoimprinting and UVO microlithography. Using this method, tunable and hierarchically

Dephasing of InAs quantum dot p-shell excitons using two-dimensional coherent spectroscopy

November 12, 2018
Author(s)
Galan Moody, Takeshi Suzuki, Rohan Singh, Marc Assman, Manfred Bayer, Arne Ludwig, Andreas Wieck, Steven T. Cundiff
The dephasing mechanisms of p-shell and s-shell excitons in an InAs self-assembled quantum dot ensemble are examined using two-dimensional coherent spectroscopy (2DCS). 2DCS provides a comprehensive picture of how the energy level structure of dots affects

Operating Hydrogen Gas Transmission Pipelines at Pressures above 21 MPa

November 12, 2018
Author(s)
Andrew Slifka, Elizabeth S. Drexler, Robert L. Amaro, Peter Bradley, Damian Lauria
The economical and efficient transportation of hydrogen gas is necessary for it to become a widespread source of energy. One way to improve the economics is to lower the cost of building hydrogen gas pipelines. The recent modification to the ASME B31.12

Evaluation of WRF-Chem Simulated Carbon Dioxide Atmospheric Transport and Emissions in the Baltimore / Washington Metropolitan Area

November 10, 2018
Author(s)
Cory R. Martin, Ning Zeng, Anna Karion, Kimberly L. Mueller, Subhomoy Ghosh, Israel Lopez Coto, Kevin Gurney, Tomohiro Oda, Kuldeep R. Prasad, Yun Liu, Russell R. Dickerson, James R. Whetstone
Urban areas are major sources of carbon dioxide (CO2) emissions, contributing to the increase in global concentrations and leading to concerns about Earth's future climate. In recent years, several urban testbeds have been implemented to improve and

In aqua electrochemistry probed by XPEEM: experimental setup, examples, and challenges

November 10, 2018
Author(s)
Slavomir Nemsak, Evgheni Strelcov, Hongxuan Guo, Brian Hoskins, Tomas Duchon, D Muller, Alexander Yulaev, Ivan Vlassiouk, Alexander Tselev, Andrei Kolmakov
Recent developments in environmental and liquid cells equipped with electron transparent graphene windows have enabled traditional surface science spectromicroscopy tools, such as XPS, PEEM, and SEM to be applied to study solid-liquid and liquid-gas

Thermal Pulse for Rapid Surface Processing of Solid-State Electrolytes

November 10, 2018
Author(s)
Chengwei Wang, Hua Xie, Weiwei Ping, Jiaqi Dai, Jamie Weaver, Guolin Feng, Yonggang Yao, Shuaiming He, Howard Wang, Karen Gaskell, Liangbing Hu
Surface contamination and degradation are two main issues leading to performance decay of ceramic-based solid-state electrolytes (SSEs). The typical strategies used to clean surface contaminants and restore ceramic materials involve mechanical polishing or
