• Runaway battery improves safety
  Overheating batteries are a serious risk, in the worst cases leading to fires and explosion. A team has now developed a simple, cost-effective method to test the safety of lithium-ion batteries, which opens up opportunities for research into new and safer batteries for the future. The researchers created an intentionally unstable battery which is more […]
• Physicists discover a copper-free high-temperature superconducting oxide
  Engineers have designed and synthesized a groundbreaking new material -- a copper-free superconducting oxide -- capable of superconducting at approximately 40 Kelvin, or about minus 233 degrees Celsius, under ambient pressure.
• A lighter, smarter magnetoreceptive electronic skin
  Imagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an electronic skin that detects and precisely tracks magnetic fields with a single global sensor. This artificial skin is not only light, transparent and […]
• E-scooter crashes mainly caused by reckless driving
  Crashes on electric scooters are mostly due to the behavior of the riders, with one-handed steering and riding in a group being some of the largest risk factors. The researchers are also concerned about riders who deliberately crash or cause dangerous situations when riding, a phenomenon that seems to be specific to electric scooters.
• These electronics-free robots can walk right off the 3D-printer
  This a robot can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer. It can also be printed in one go, from one material.
• Good vibrations: Scientists discover a groundbreaking method for exciting phonon-polaritons
  Newly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller long-wave infrared light sources and more efficient device cooling.
