• Breakthrough: Dramatic increase in thermoelectric efficiency achieved

    Two hundred years ago scientists discovered the thermoelectric effect: Certain materials can convert heat into electricity and vice versa; trouble is, most materials which conduct electricity also conduct heat, so their temperature equalizes quickly; until now: Boston College, MIT researchers solve this vexing problem

  • New material captures carbon dioxide

    Georgie Tech researchers developed material which captures CO2 from the chimneys of coal-fired power plants and other generators of the greenhouse gases

  • European consortium to make RFID tags more affordable

    To make RFID more popular, there is a need to make them cheaper; a team of major technology companies is confident that the cost will be reduced once the tags can be printed because electrically conductive and semiconducting plastics can be used in high-volume printing processes

  • Invisibility cloak for nanoparticles designed

    Researchers design invisibility cloak for nanoparticles; the new particle invisibility cloak will help create a vast array of new material technologies that combine unknown property combinations such as strength and durability with optical transparency

  • Sea cucumber inspires new plastic for body armor, brain implants

    Sea cucumbers’ skin is usually supple, allowing them to slide through narrow spaces between rocks and corals; when touched, however, a defensive reaction makes their skin go rigid in seconds, thanks to enzymes that bind protein fibers together; researchers apply this process to clothing, creating garments which switch stiffness in response to a pulse of electricity

  • Nano-bristle clothes to generate power from body motions

    Yellow Jackets researcher develops energy-generating fiber: If clothes are made from this piezoelectric fabric, the wearer’s body motions would produce useful amounts of power

  • Day of ultra-clean engine nears

    One of the major obstacles facing the development of ultra-clean car engines is the need for permanent-magnet electric motors to operate well at temperatures up to 200 degrees Celsius; Iowa researchers offer a way to create such magnets

  • Breakthrough: Acoustic cloak theoretically possible

    Invisibility cloak — deflecting microwaves around a cloaked object and restoring them on the other side, as if they had passed through empty space — has already been demonstrated; Duke researcher now shows that an acoustic cloak is theoretically feasible: Sound waves would travel seamlessly around the cloaked object and emerge on the other side without distortion; submarines could be hidden from sonar

  • Helmet sensors measure munition impact

    Worried about ever-more-powerful IEDs, the Army is providing soldiers from the 101st Airborne Division with helmets equipped with sensors which measure the energy wave generated by an “event” and the acceleration or jolt that follows

  • Accreditation program for labs which test body armor

    In the last three decades, the lives of more than 3,000 officers were saved by body armor; many, though, lost their lives or were injured when they were wearing ineffective body armor; NIST, Justice create program for accrediting labs which test and certify body armor

  • New London center to develop stronger ceramic materials

    Imperial College London launches Structural Ceramic Center; center will research and develop dramatically stronger and more durable structural ceramics made of inorganic materials such as oxides, carbides, and nitrides; new materials will be used in vehicle and body armor, reusable space craft, and pebble beds in nuclear reactors
