A detailed nano-mechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes. Anodes – the negative electrodes – based on silicon can theoretically store up to ten times more lithium ions than conventional graphite electrodes,
PICATINNY ARSENAL, N.J. — Engineers at Picatinny Arsenal are working on the first new lethal hand grenade in more than 40 years, which is designed to give greater flexibility to the warfighter. The multi-purpose hand grenade design will provide both fragmentation and blast overpressure more effectively and safely than its legacy counterparts. Once fielded, Soldiers
As the U.S. Army readies to bring its current crop of Humvees into the 21st century with a new vehicle, reconnaissance officials are also looking to replace the Humvee”s pre-World War II .50-caliber machine gun with a version of the Apache helicopter’s cannon in 2019. The Army has embarked on a major project to replace
Superconductivity is a hot phenomenon that occurs only at very cold temperatures. Finding ways to change that and make superconductivity practical at higher temperatures is a major goal for physicists and engineers. One possibility involves the metallic phase of hydrogen, theorized to be superconducting at ambient temperatures but yet to be achieved in practice. By

Achieving Affordable System Operational Effectiveness. The Program Manager (PM) can address the return on investment (ROI) of ‘up-front’ expenditures by designing for the optimal balance between performance (technical and supportability), life-cycle costs, schedule, and process efficiency. A development program that targets only some categories of technical performance capability; or fails to optimize system Reliability, Availability,
On today”s battlefield, approximately four to five support soldiers back up each combat-arms soldier, especially in an armored brigade task force. The reason for this becomes clear when considering the fuel, food and ammunition required on a daily basis by these units. As it has been throughout history, support units are vital lifelines to a
Fabrics that can generate electricity from physical movement have been in the works for a few years. Now researchers at Georgia Institute of Technology have taken the next step, developing a fabric that can simultaneously harvest energy from both sunshine and motion. Combining two types of electricity generation into one textile paves the way for
Tokyo, April 25, 2016 – A thermoelectric (TE) device using cutting edge thermoelectric conversion technology has been created by a team comprising NEC Corporation, NEC TOKIN Corporation and Tohoku University. The new technology, known as the spin Seebeck effect, has conversion efficiency 10 times higher than the conventional method *3. Thermoelectric conversion technology that converts
Army scientists are on the trail of new high-performing energetic materials. Scientists at the U.S. Army Research Laboratory recently synthesized a new material called bis-isoxazole tetranitrate, or BITN, with potential applications in propulsion and lethality. “BITN has a strong potential for improving insensitive munitions characteristics for gun and rocket propellants” said Dr. Jesse J. Sabatini,
