Spintronics: Chiral damping

February 24, 2016
Author(s)
Kyoung-Whan Kim, Hyun-Woo Lee
Many objects in nature prefer to spiral in one particular direction to the other. A nanostructured magnetic system with strong spin-orbit coupling now shows that the energy loss is also chiral.

Uranium Ion Yields from Monodisperse Uranium Oxide Particles

February 24, 2016
Author(s)
Nicholas E. Sharp, John D. Fassett, David S. Simons
Secondary ion mass spectrometry (SIMS) plays an important role in nuclear forensics through its ability to identify isotopic ratios of particles accurately and precisely from samples obtained by inspectors [1]. As the particle mass can be on the order of

Current Standards Landscape for Smart Manufacturing Systems

February 23, 2016
Author(s)
Yan Lu, Katherine C. Morris, Simon P. Frechette
The future of manufacturing lies in being able to optimize the use of resources to produce high quality product and adapt quickly to changing conditions. From smaller lot sizes, to more customization, to sudden changes in supply chain; the variability that

Interlaboratory study towards a climate-specific test: spectroscopic characterizations of EVA in glass/EVA/glass systems

February 23, 2016
Author(s)
Jae Hyun Kim, Christopher M. Stafford, Yadong Lyu, Li C. Yu, Chiao-Chi Lin, Tinh Nguyen, Xiaohong Gu
EVA as an encapsulant material is exposed to various UV irradiation, thermal cycles, and humidity conditions. Degradation of EVA can reduce not only power generation due to yellowing, but also a structural integrity of a PV module. In order to investigate

The New Frontiers in Computational Modeling of Material Structures

February 23, 2016
Author(s)
Vijay Srinivasan, Jarek Rossignac, Vadim Shapiro, William Regli
We are witnessing the emergence of a new paradigm in the modeling of material structures. It stems from the digitization of manufacturing and is fueled by advances in additive manufacturing and material science. This paper strives to provide a critical

2015 TMS William Hume-Rothery Award and Symposium

February 22, 2016
Author(s)
Ursula R. Kattner
The symposium was titled “Multicomponent Alloy Metallurgy: Bridge from Materials Science to Materials Engineering” with focus on the physical metallurgy of alloys with three or more components. The topics of interest for the symposium included

An Optomechanical Accelerometer with a High-Finesse Hemispherical Optical Cavity

February 22, 2016
Author(s)
Yiliang Bao, Felipe Guzman, Arvind Balijepalli, John Lawall, Jacob Taylor, Thomas W. LeBrun, Jason J. Gorman
A new design for an optomechanical accelerometer is presented. The design includes a hemispherical optical cavity that can achieve high finesse and a proof mass that is well-constrained by silicon nitride beams. Based on previous work and analysis, the

Pulsed KrF excimer laser dopant activation in nanocrystal silicon in a silicon dioxide matrix

February 22, 2016
Author(s)
Tian Zhang, Brian Simonds, Keita Nomoto, Binesh Puthen Veettil, Ziyun Lin, Ivan Perez Wurfl, Gavin Conibeer
We demonstrate that a pulsed KrF excimer laser (λ=248 nm, τ=22 ns) can be used as a post-furnace annealing method to greatly increase the electrically active doping concentration in nanocrystal silicon (ncSi) embedded in SiO2. The application of a single
