  • New portable tool analyzes microbes in the environment January 27, 2020
    Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms - too tiny to be seen by the naked eye - and their response to threats to their ecosystems. Researchers have created just such a tool, a portable device that could be used to assess […]
  • Principles for a green chemistry future January 24, 2020
    Researchers show how green chemistry is essential for a sustainable future.
  • Engineers examine lithium battery defects January 24, 2020
    Lithium dendrites cause poor performance and even explosions in batteries with flammable liquid electrolytes. How these dendrites grow, even with a solid electrolytes, is still a mystery, but materials engineers study the conditions that enable dendrites and how to stop them.
  • Predictive touch response mechanism is a step toward a tactile internet January 23, 2020
    A team of researchers has developed a method for enhancing haptic feedback experiences in human-to-machine applications that are typical in the Tactile Internet.
  • New understanding of condensation could lead to better power plant condenser, de-icing materials January 23, 2020
    For decades, it's been understood that water repellency is needed for surfaces to shed condensation buildup - like the droplets of water that form in power plant condensers to reduce pressure. New research shows that the necessity of water repellency is unclear and that the slipperiness between the droplets and solid surface appears to be […]
  • Deep-sea osmolyte makes biomolecular machines heat-tolerant January 22, 2020
    Researchers have discovered a method to control biomolecular machines over a wide temperature range using deep-sea osmolyte trimethylamine N-oxide (TMAO). This finding could open a new dimension in the application of artificial machines fabricated from biomolecular motors and other proteins.
  • Less may be more in next-gen batteries January 22, 2020
    Engineers build full lithium-ion batteries with silicon anodes and an alumina layer to protect cathodes from degrading. By limiting their energy density, the batteries promise excellent stability for transportation and grid storage use.
  • Flooding damage to levees is cumulative -- and often invisible January 21, 2020
    Recent research finds that repeated flooding events have a cumulative effect on the structural integrity of earthen levees, suggesting that the increase in extreme weather events associated with climate change could pose significant challenges for the nation's aging levee system.
  • Designer-defect clamping of ferroelectric domain walls for more-stable nanoelectronics January 21, 2020
    Engineered defects in ferroelectric materials provides key to improved polariaztion stability, a significant step forward for domain-wall nanoelectronics in data storage. Researchers achieved stability greater than one year (a 2000% improvement).
  • Spider-Man-style robotic graspers defy gravity January 17, 2020
    Traditional methods of vacuum suction and previous vacuum suction devices cannot maintain suction on rough surfaces due to vacuum leakage, which leads to suction failure. Researchers have developed a zero-pressure difference method to enhance the development of vacuum suction units. Their method overcame leakage limitations by using a high-speed rotating water ring between the surface […]
