Designing With Plastics for Military Equipment

U.S. soldiers carry loads of equipment and protective gear that can weigh anywhere from 45 to 130 pounds. This is more than enough to quickly tire even the most well-conditioned personnel, contributing to reduced mobility and impaired decision-making that could result in casualties.

Phonon Confinement Effect in TiO2 Nanoparticles as Thermosensor Materials

TiO2 or ZnO nanoparticles (NPs) have a very strong finite-size dependency in their Raman spectra or photoluminescence (PL) spectra due to the phonon confinement effect or the quantum confinement effect. Together with a fast grain growth kinetics and a high stability under high temperature and pressure, they can forensically retain the complete thermal history of an event. By spatially distributing these NPs during thermal events such as blasts or weapon tests, a spatially and temporally non-uniform thermal environment can be determined by a direct read off their Raman or PL spectra at various locations.

High-Voltage Switching Device Testing using the AARTS HV System

Accel-RF Instruments (ARF) has developed a test system capable of measuring reliability under a variety of conditions for switching power applications up to 1kV (off) and 25A (on) at a up to 1-MHz switching frequency (depending on high voltage level). By leveraging our existing RF burn-in tray platform, support for testing of multiple devices under elevated temperature stimulus in a small physical area is efficiently facilitated.

Content Addressable Memory (CAM) Technologies for Big Data and Intelligent Electronics Enabled By Magneto-Electric Ternary CAM

Content addressable memory (CAM) is one of the most promising hardware solutions for high-speed data searching and has many practical applications such as anti-virus scanners, internet protocol (IP) filters, and network switches. Since CAM stores the data in its internal memory elements and compares them with the search data in parallel, it can achieve much faster speed compared to the software lookup.

pH-Dependent Spin State Population and 19F NMR Chemical Shift Via Remote Ligand Protonation in An Iron(II) Complex

The development of transition metal-based molecules and materials that can be switched between low-spin and high-spin electronic states has constituted a highly active area of research over the past several decades. Indeed, the magnetic bistability of such spin-crossover compounds make them potential candidates for molecular switches and chemical sensors, as the spin transition can be controlled by a number of external stimuli, such as temperature, pressure, and light.
