Dominant factors for fracture at the micro-scale in electrodeposited nickel alloys

August 1, 2020
Author(s)
May L. Martin, Li-Anne Liew, David T. Read, Todd Christensen, Frank W. DelRio, John Geaney
Two different LIGA electrodeposited nickel alloys displayed distinct fracture modes after meso- scale tensile testing. The Ni-Co alloy failed in a ductile manner, while the Ni-Fe alloy failed in a more brittle-appearing manner. Various factors affecting

Early stage nucleation in barium disilicate glass

August 1, 2020
Author(s)
Ling Cai, Randall E. Youngman, David E. Baker, Aram Rezikyan, Minghui Zhang, Bryan Wheaton, Indrajit Dutta, Bruce G. Aitken, Andrew J. Allen
Early stage nucleation in silicate glasses is often evidenced by formation of nanosized regions that are stoichiometrically different from the surrounding matrix. The structural origin of these early stage nucleation sites is of great interest in gaining a

NIST cloud computing forensic science challenges:

Martin Herman, Michaela Iorga, Ahsen Michael Salim, Robert H Jackson, Mark R Hurst, Ross Leo, Richard Lee, Nancy M Landreville, Anand Kumar Mishra, Yien Wang, Rodrigo Sardinas

Numerical and Experimental Studies of Extinguishment of Cup-Burner Flames by C6F12O

August 1, 2020
Author(s)
Fumiaki Takahashi, Viswanath R. Katta, Valeri Babushok, Gregory Linteris
The extinguishment processes of cup-burner flames by adding a halon-replacement fire-extinguishing agent C6F12O (Novec 1230) to coflowing air in normal gravity have been studied computationally and experimentally. The time-dependent, axisymmetric numerical

The Antioxidant Vitamin E as a Membrane Raft Modulator: Tocopherols do not Abolish Lipid Domains

August 1, 2020
Author(s)
Mitchell DiPasquale, Michael H. Nguyen, Brett W. Rickeard, Nicole Cesca, Christopher Tannous, Stuart R. Castillo, John Katsaras, Elizabeth Kelley, Frederick A. Heberle, Drew Marquardt
A great deal of individuals across North America regularly supplement their diet with the antioxidant, vitamin E. This billion-dollar supplementation industry encourages the use of vitamin E with little evidence supporting its actual health benefits

Data-driven characterization of computational models for powder-bed-fusion additive manufacturing

July 31, 2020
Author(s)
Yan Lu, Zhuo Yang, Paul W. Witherell, Wentao Yan, Kevontrez Jones, Gregory Wagner, Wing-Kam Liu, Jason C. Fox
Computational modeling for additive manufacturing has proven to be a powerful tool to understand the physical mechanisms, predict fabrication quality, and guide design and optimization. Varieties of models have been developed with different assumptions and

Effect of Molecular Weight and Layer Thickness on the Dielectric Breakdown Strength of Neat and Homopolymer Swollen Lamellar Block Copolymer Films

July 31, 2020
Author(s)
Saumil Samant, Monali Basutkar, Maninderjeet Singh, Ali Masud, Christopher A. Grabowski, Kim Kisslinger, Joseph Strzalka, Guangcui Yuan, Sushil K. Satija, Ikeoluwa Apata, Dharmaraj Raghavan, Michael Durstock, Alamgir Karim
Designing next generation light-weight pulsed power sources hinges on understanding the factors influencing the performance of high energy density storage materials. In prior work, we demonstrated the use of Cold Zone Annealing with Soft Shear (CZA-SS) as

General Access Control Guidance for Cloud Systems

July 31, 2020
Author(s)
Chung Tong Hu, Michaela Iorga, Wei Bao, Ang Li, Qinghua Li, Antonios Gouglidis
This document presents cloud access control characteristics and a set of general access control guidance for cloud service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). Different service

The Certification of Standard Reference Material 1979: Powder Diffraction Line Profile Standard for Crystallite Size Analysis

July 31, 2020
Author(s)
James Cline, Marcus Mendenhall, Joseph J. Ritter, David R. Black, Albert Henins, John E. Bonevich, Pamela S. Whitfield, James J. Filliben
This rather long-standing project has resulted in a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) for the analysis of crystallite size from a consideration of powder diffraction line profile broadening. It consists

Brightly Luminescent CsPbBr3 Nanocrystals through Ultracentrifugation

July 30, 2020
Author(s)
Jeffrey Fagan, Erik K. Hobbie, Aaron Forde, Richard D. Schaller, salim thomas, samuel brown, Matthew B. Kurtti, dmitri kilin
Colloidal lead-halide-perovskite nanocrystals (NCs) offer broad color tunability with bright photoluminescence (PL), fast lifetime, and narrow spectral linewidth. Because emission is tuned primarily through chemical composition, quantum confinement and
