Spin-Orbit Coupled Molecular Quantum Magnetism Realized in Inorganic Solid

September 21, 2016
Author(s)
Sang-Youn Park, S.-H. Do, K.-Y. Choi, J.-H. Kang, Dongjin Jang, B. Schmidt, Manuel Brando, B.-H. Kim, D.-H. Kim, Nicholas Butch, Seongsu Lee, Sungdae Ji
The molecular magnetism, representing an isolated spin state, is of particular interest due to characteristics of quantum magnetism with quantum tunneling phenomena underlying qubits or molecular spintronics for the quantum information devices. Such

The Glass Transition of a Single Macromolecule

September 21, 2016
Author(s)
Jack F. Douglas, David Simmons, Weston L. Merling, Jack Mileski
The glass transition of a single macromolecule in isolation is relevant to the dynamics of systems including dilute solutions of synthetic polymers and biological macromolecules such as proteins. Here we employ molecular dynamics simulation to show that a

A Probabilistic Network Forensics Model for Evidence Analysis

September 20, 2016
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Modern-day attackers tend to use sophisticated multi-stage/multi-host attack techniques and anti-forensics tools to cover their attack traces. Due to the current limitations of intrusion detection and forensic analysis tools, reconstructing attack

After oxidation, zinc nanoparticles lose their ability to enhance responses to odorants

September 20, 2016
Author(s)
Samantha Hagerty, Yasmine C. Daniels, Melissa Singletary, Oleg Pustovyy, Ludmila Globa, William A. MacCrehan, Shinichiro Muramoto, June W. Lau, Edward Morrison, Iryna Sorokulova, Vitaly Vodyanoy, Gheorghe Stan
Electrical responses of olfactory sensory neurons to odorants were examined in the presence of zinc nanoparticles of various sizes and degrees of oxidation. The zinc nanoparticles were prepared by the underwater electrical discharge method and analyzed by

An analysis of technologies and standards for designing smart manufacturing systems

September 20, 2016
Author(s)
Boonserm Kulvatunyou, Katherine C. Morris, Sangsu Choi, Kiwook Jung
Smart manufacturing is defined by high degrees of automation. Automation, in turn, is defined by clearly defined processes. The use of standards in this environment is not just common place but essential to creating repeatable and reliable systems. As with

Extinguishment and Enhancement of Propane Cup-Burner Flames by Halon and Alternative Agents

September 20, 2016
Author(s)
Gregory T. Linteris, Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok
Computations of cup-burner flames in normal gravity have been performed to reveal the combustion inhibition and enhancement by the CF3Br (halon 1301) and potential alternative fire-extinguishing agents (C2HF5, C2HF3Cl2, and C3H2F3Br). The time-dependent

Gas-Phase Interactions of Phosphorus Containing Compounds with Cup-Burner Diffusion Flames

September 20, 2016
Author(s)
Gregory T. Linteris, Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok
The effects of phosphorus-containing compounds (PCC) on the extinguishment and structure of methane-air coflow diffusion flames, in the cup-burner configuration, have been studied computationally. Dimethyl methylphosphonate (DMMP), trimethyl phosphate (TMP

Interlaboratory Analytical Comparison of Fatty Acid Concentrations in Serum or Plasma

September 20, 2016
Author(s)
Michele M. Schantz, Carissa Powers, Schleicher Rosemary, Joseph Betz, Stephen A. Wise
The National Institute of Standards and Technology, in collaboration with the National Institutes of Health Office of Dietary Supplements and the Centers for Disease Control and Prevention, is conducting an accuracy-based program for improving the

Signatures of intracrystallite and intercrystallite limitations of charge transport in polythiophenes

September 20, 2016
Author(s)
Kiarash Vakhshouri, Brandon Smith, Edwin Chan, Chenchen Wang, Alberto Salleo, Cheng Wang, Alexander Hexemer, Enrique Gomez
Charge carrier mobilities in conjugated semicrystalline polymers depend on morphological parameters such as crystallinity, crystal orientation, and connectivity between ordered regions. Despite recent progress in the development of conducting polymers, the

Spintronic nanodevices for bioinspired computing

September 20, 2016
Author(s)
Julie Grollier, Damien Querlioz, Mark D. Stiles
The challenge of fabricating bio-inspired hardware is building ultra-high density networks out of complex processing units interlinked by tunable connections. Nanodevices exploiting spin electronics (or spintronics) can be a key technology in this context

Spintronics

September 20, 2016
Author(s)
Hideo Ohno, Mark D. Stiles, Bernard Dieny
Scope: This special issue covers recent developments in spintronics, where the spin degree of freedom of electrons is used to harness otherwise inaccessible capabilities. We have witnessed a wide range of progress, particularly in the past 10 years

A Q-band free-space characterization of carbon nanotube composites

September 19, 2016
Author(s)
Ahmed M. Hassan, Jan Obrzut, Edward Garboczi
We present a free-space measurement technique for non-destructive non-contact electrical and dielectric characterization of nano-carbon composites in the Q-band frequency range of 30 GHz to 50 GHz. The experimental system and error correction model

Compressed-Liquid Densities of Three Reference Fuels for Combustion Testing

September 19, 2016
Author(s)
Stephanie L. Outcalt
Compressed-liquid densities of three aviation fuels have been measured with a vibrating-tube densimeter. The measurements were made from 270 K to 470 K, and 0.5 MPa to 45 MPa and have an overall combined uncertainty of 0.81 kg.m-3. The data from each of

Long term stability of ultra high molar mass polyethylene fibres

September 19, 2016
Author(s)
Amanda Forster, Aaron Forster, Joannie Chin, Sylvain H. Petit, Kai-Li Kang, Nicholas G. Paulter Jr., Kirk D. Rice, Don Jenket II, Mohamad Al-Sheikhly
Abstract. The performance of ultra-high molar mass polyethylene (UHMMPE) fibres for ballistic protection is predicated on the development of a highly aligned molecular structure that allows the polymer to exhibit a superior strength in the axial direction
