Apr 11, 2022 (Nanowerk News) Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research group coordinated by Antonio Ambrosio at the IIT-Istituto Italiano di...
New graphene transistor could cut 5% from world’s digital energy budget
Apr 11, 2022 (Nanowerk News) A new spin on one of the 20th century’s smallest but grandest inventions, the transistor, could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet. Following years of innovations from the University of...
Photocatalysts with built-in electric field helps to remove pollutants from water
Apr 11, 2022 (Nanowerk News) A research team led by Prof. WU Zhengyan from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) has recently introduced a high-efficiency Z-scheme photocatalyst to deal with contaminants in water. This new solution has been published in ACS Applied Nano...
Magnetic property in a specific class of materials enables light manipulation on the nanoscale
Apr 11, 2022 (Nanowerk News) A major research challenge in the field of nanotechnology is finding efficient ways to control light, an ability essential for high-resolution imaging, biosensors and cell phones. Because light is an electromagnetic wave that carries no charge itself, it is difficult to manipulate with voltage or...
Tunable graphene nanocomposite temperature alarm sensor
Apr 11, 2022 (Nanowerk News) Back in 2018, we reported on fire alarm wallpaper that was fabricated using fire-resistant inorganic paper as a coating material based on ultralong hydroxyapatite nanowires and graphene oxide. It was arranged with an electrical connection between the composite paper, an alarm lamp, and an alarm...
Astronomers capture surprising changes in Neptune’s temperatures
Apr 11, 2022 (Nanowerk News) An international team of astronomers have used ground-based telescopes, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track Neptune’s atmospheric temperatures over a 17-year period. They found a surprising drop in Neptune’s global temperatures followed by a dramatic warming at its south...
