Dramatically longer-lasting, faster-charging and safer lithium metal batteries may be possible, according to Penn State research, recently published in Nature Energy.
A team of multi-disciplinary scientists and engineers at the University of Illinois at Urbana-Champaign have discovered a new, more precise, method to create nanoscale-size electromechanical devices. Their research findings are published in Nature Communications.
MIT engineers have developed a heat-rejecting film that could be applied to a building's windows to reflect up to 70 percent of the sun's incoming heat. The film is able to remain highly transparent below 32 degrees Celsius, or 89 degrees Fahrenheit. They estimate that if every exterior-facing window in a building were covered in this film, the building's air conditioning and energy costs could drop by 10 percent.
A new method developed at MIT can greatly extend the life of inexpensive, compact, lightweight metal-air batteries.
To break out of Earth's lower orbit, hypersonic vehicles must reach speeds greater than Mach 5. At these hypersonic speeds, the air particles and gases that flow around the vehicle and interact with the surfaces generate heat and create shock waves that disturb the flow's equilibrium. New research at the University of Illinois at Urbana-Champaign created a model to simulate and better understand flow transitions.
A team of Penn Engineers has demonstrated a new material they call 'nanocardboard,' an ultrathin equivalent of corrugated paper cardboard. A square centimeter of nanocardboard weighs less than a thousandth of a gram and can spring back into shape after being bent in half. Nanocardboard's stiffness-to-weight ratio makes it ideal for aerospace and microrobotic applications, where every gram counts.
Researchers at CU Boulder have uncovered the statistical rules that govern how gigantic colonies of fire ants form bridges, ladders and floating rafts.
ORNL story tips: ORNL's simulation shows 40 percent fuel savings when cars drive themselves; colliding tin isotopes helps scientists better understand unstable nuclei in exploding stars; new method to control HVACs in buildings provides grid stability, occupant comfort; AK Steel uses neutrons to see how new steel for vehicle components performs during various manufacturing processes.
At the 2018 Oceans Conference, Chief of Naval Research Rear Adm. David Hahn discussed the goals of the US Navy's Task Force Ocean, a signature program of Chief of Naval Operations Adm. John Richardson. TFO is designed to reinvigorate the Navy's commitment to ocean sciences, advancing its tactical advantage through a better knowledge of the ocean environment and its impact on sensors, weapons and operations.
A new, more powerful generation of a patented Southwest Research Institute magnetostrictive sensor withstands extreme temperatures, automatically adjusts frequencies and incorporates a stronger magnet. The compact magnetostrictive transducer (MsT™) more accurately detects potential problems in oil, gas and chemical industry metal and nonmetal structures such as pipelines, storage tanks and anchor rods.
