Argonne and Strem Chemicals to Deliver Next-Gen Battery Materials

The U.S. Department of Energy”s (DOE”s) Argonne National Laboratory has teamed up with Strem Chemicals, Inc. to provide industry and the battery research community with next-generation materials that could improve energy storage. Strem, a manufacturer and distributor of specialty chemicals founded in 1964, has licensed 23 separate pieces of intellectual property from Argonne and will

New Tech Promises to Boost Electric Vehicle Efficiency, Range

Researchers at North Carolina State University have developed a new type of inverter device with greater efficiency in a smaller, lighter package – which should improve the fuel-efficiency and range of hybrid and electric vehicles. Electric and hybrid vehicles rely on inverters to ensure that enough electricity is conveyed from the battery to the motor

TARDEC, General Motors Partner to Develop Fuel-Cell Vehicle

General Motors and the U.S. Army Tank Automotive Research, Development and Engineering Center will reveal a Chevrolet Colorado-based fuel cell electric vehicle in October at the fall meeting of the Association of the United States Army in Washington. The vehicle is being developed under an agreement signed in 2015 between TARDEC and GM. The collaboration

Focus: Smoke Rings in Light

A newly discovered optical vortex forms a ring around many intense laser pulses but was never noticed before. In a typical optical vortex, light waves twist around a dark line, or hole, through the center of a light beam. Researchers have now uncovered an entirely different type of optical vortex that forms a ring, or

Vibration Ring Prototype

Machine vibration often originates with rotating driveline components such as rotors, gears, bearings, and fans. Such vibration is the source of unwanted noise and can be destructive to the machine. The vibration ring is a mechanism that provides an indirect damping effect, and is rigid enough to be mounted within the driveline. The mechanical structure

NRL Demonstrates New Fiber Laser Sensor Technology for Structural Health Monitoring Systems

Researchers at the U.S. Naval Research Laboratory (NRL), Optical Sciences Division, in collaboration with the laboratory’s Material Science Division, for the first time have demonstrated successful detection of acoustic emission from cracks in riveted lap joints using a distributed feedback fiber laser-acoustic emission sensor. “An automated, in-situ structural health monitoring (SHM) system, capable of monitoring

Recycling Technology Converts Plastic Waste to Energy

NASA’s expertise in rocket engine improvement helps optimize plastic recycling process equipment. As good as it feels to throw plastic items into the recycling bin, the fact is most of that plastic goes unrecycled, according to Jim Garrett, a veteran of the oil and gas industry. “It’s a dirty little secret in America that 90

Iodine-Compatible Hall Effect Thruster

The Hall effect thruster (HET) was designed for long-duration operation with gaseous iodine as the propellant. Iodine is an alternative to the state-of-the-art propellant xenon. Compared to xenon, iodine stores as a solid at much higher density and at a much lower pressure. Because iodine is a halogen, it is reactive with some of the

Fungi Recycle Rechargeable Lithium-ion Batteries

Although rechargeable batteries in smartphones, cars and tablets can be charged again and again, they don”t last forever. Old batteries often wind up in landfills or incinerators, potentially harming the environment. And valuable materials remain locked inside. Now, a team of researchers is turning to naturally occurring fungi to drive an environmentally friendly recycling process

Air-Breather Propulsion Test: ISRO

The Indian Space Research Organisation (ISRO) is set to conduct air-breathing propulsion experiment using its RH-560 rocket fitted with a supersonic combustion ramjet (Scramjet) engine on August 28 from Sriharikota. According to ISRO Chairman A.S. Kiran Kumar, while the test would take place on August 28, the GSLV-F05 rocket with an indigenous cryogenic engine would

Army’s Rapid Capabilities Office to Be Stood Up in September

WILLIAMSBURG, Va. — An Army rapid capabilities office, which will aim to quickly field technology and put it in the hands of soldiers, is nearing its debut, said the undersecretary of the Army Aug.16. “That roll out will be in September,” said Patrick Murphy at the U.S. Army Innovation Summit 3, which was hosted by

Revolutionary Camera Recording Propulsion Data Completes Groundbreaking Test

While thousands turned out to watch NASA’s Space Launch System (SLS) recently complete a full-scale test of its booster, few were aware of the other major test occurring simultaneously. NASA’s High Dynamic Range Stereo X (HiDyRS-X) project, a revolutionary high-speed, high dynamic range camera, filmed the test, recording propulsion video data in never before seen
