Army Research Laboratory developing poly(urethane urea) elastomers (PUUs) for combat helmets

armyhelmetmaterial

Armor used to protect soldiers and vehicles has traditionally been comprised of ceramics, metals, or lightweight fiber-reinforced composites, which are typically based on stiffness (the resistance of a material against deformation) and toughness (the ability to absorb energy and plastically deform prior to fracture). The Army’s current combat helmet is made …

Thermoelectric Generators to generate power for future homes, vehicles, consumer and Military equipment

thermoelectric

A thermoelectric (TE) device can directly convert heat emanating from the Sun, radioisotopes, automobiles, industrial sectors, or even the human body to electricity. Many electrical and mechanical devices, such as car engines, produce heat as a byproduct of their normal operation. It’s called “waste heat,” and its existence is required by …

Researchers employing Simulation and Machine-learning techniques for accelerated discovery of new application specific materials

machinelearnmaterials

Finding new materials has traditionally been guided by intuition and trial and error,” said Turab Lookman, a physicist and materials scientist in the Physics of Condensed Matter and Complex Systems group at Los Alamos National Laboratory. “But with increasing chemical complexity, the combination possibilities become too large for trial-and-error approaches …

Solid state cooling based on magnetocaloric, electrocaloric, and mechanocaloric materials advancing to replace present environmentally damaging refrigeration technologies

elctrocloric

Current cooling technology, such as that found in fridges and air conditioning systems, exploits the changes in temperature when gases are compressed and expanded. This technology often uses environmentally damaging greenhouse gases. The search for materials with large caloric effects has become a major challenge in material science due to …

Self-healing materials leading to automatic repairing smartphones, and flexible lightweight armor system providing blast and ballistic protection

4d-printing-with-smart-materials-22-638

The “self-healing” materials are those artificial (synthetic) substances that automatically repair themselves without any overt diagnosis of the problem or intervention by a human being. Self-healing materials, could have applications from bridges and buildings that repair their own cracks to car fenders made from shape-memory polymers that automatically flex back …

Gallium Nitride entering mainstream to enable IoT revolution, Cellular 5G to Military Communications, Radars and Jammers

gan

GaN is a semiconductor material that can amplify high power radio frequency signals efficiently at microwave frequencies  to enhance  a system’s range. Therefore it has become the technology of choice for high-RF power applications that require the transmission of signals over long distances such as EW, radar, base stations and satellite communications.   The adoption of GaN has been advancing significantly over the last five years with several thousand …

New technologies and materials for thermal Management for Mission-Critical Military Ground, Sea, Air and Space systems

power2

Cooling accounts for around 15% of the energy used in buildings in the US and contributes heavily to greenhouse-gas emissions. Worldwide, energy consumption related to cooling is expected to surpass that used for heating by 2070. Cooling challenges are only exacerbated by the harsh environments in which increasing numbers of …
