Ultrafine Fibers Could Revolutionize Body Armor

Researchers at MIT have developed a process, called gel electrospinning, that can produce ultrafine fibers - whose diameter is measured in nanometers, or billionths of a meter - that are exceptionally strong and tough. These fibers, which should be inexpensive and easy to produce, could be choice materials for many applications, such as protective armor and nanocomposites.

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.

Loop Thermosyphons

Two-phase cooling has been utilized in the electronics cooling industry for many decades, with possibly the most well-known adaptation being the heat pipe. Heat pipes are capillary-driven, two-phase devices that rely on the boiling and condensation of a working fluid to transfer heat significant distances with minimal temperature gradient. The flow of the working fluid inside of a heat pipe is facilitated by a capillary wick structure that relies on surface tension to return the condensed liquid to the heat generating components. Heat pipes have found their way into a large number of industries and applications because of their high performance, high reliability, and low cost. Unfortunately, as the electronics industry’s insatiable quest for smaller, higher-powered devices soldiers on, the discrete cooling power of the heat pipe approaches obsolescence.

Additive Manufacturing Materials for RF Components

The Army Aviation and Missile Research, Development, and Engineering Center (AMRDEC) Weapons Development and Integration (WDI) Directorate has a program known as PRIntable Materials with Embedded Electronics (PRIME2). PRIME2 will integrate RF and electronics into additive manufacturing processes to reduce size, weight, and overall cost of these components and subsystems. This program will advance the state of the art in printable electronics, and deliver a materials database, process development, modeling, and simulation of 3D-printed objects with embedded conductive elements, passive prototypes, and RF prototypes. PRIME2 will create a new fabrication capability (applied to electronics and RF technology areas), weight reduction, higher reliability, and on-demand (local and immediate) spare components in the field.

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.
