Electrical Characterization of Crystalline UO2, THO2 and U0.71TH0.29O2

Tracking and identifying radiation sources in the age of nuclear proliferation and well- resourced non-state actors is a national priority. Current neutron detection methods favor large detector volumes and long data collection times. Additionally, portable neutron detection methods have persistent problems with low signal-to-noise (small pulse height) and require large applied voltages.

The FACE™ of Military Modernization

U.S. rival countries have been rapidly modernizing their militaries, with publicized advances that pose credible challenges to U.S. supremacy in all aspects of warfare: air, land, sea, space and cyberspace. On January 19, 2018 Secretary Mattis discussed the National Defense Strategy and emphasized the need to modernize key capabilities to address these threats. He stated: “To keep pace with our times, the department will transition to a culture of performance and affordability that operates at the speed of relevance. Success does not go to the country that develops a new technology first, but rather, to the one that better integrates it and more swiftly adapts its way of fighting. Our current bureaucratic processes are insufficiently responsive to the department's needs for new equipment. We will prioritize speed of delivery, continuous adaptation and frequent modular upgrades.”

Multi-Agent RF Propagation Simulator

A desirable interface between multi-agents is through over-the-air RF connections that include not only the intended direct RF communications paths but also highly variable multi-ray propagation, range attenuation, external RF influences, and near-earth influence. These influences are all difficult to predict, control, and repeat in an outdoor environment. This outdoor testing, as has traditionally been done, is extremely expensive while simultaneously providing fewer data points than more controlled events and the testing events are generally not repeatable.

Matrix-Free Assisted Laser Desorption Ionization Using Metal-Organic Frameworks

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.

Hydraulic Cylinder Position Sensor Technology

As the demand for greater control and functionality increases, position-sensor-instrumented hydraulic cylinders are becoming more important in the heavy industry, mobile equipment, and subsea worlds. Position sensors for feedback in hydraulic or pneumatic cylinders have typically used one of three technologies: Linear Variable Inductance Transducers (LVITs), variable resistance potentiometers (Pots), or magnetostrictive transducers (MLDTs). While other sensor technologies have occasionally been used in these applications, the focus of this article is a comparison among these three popular technologies. Ultimately, a user or systems integrator must determine the exact requirements of the application and which technology best satisfies them on a total installed cost versus performance basis. The strengths and weaknesses of linear variable inductance, variable resistance pots, and magnetostrictive sensors are all examined below, together with a feature-by-feature comparison chart.
