A quantum ruler to explore the strange properties of twisted 2D materials
Oct 05, 2023 (Nanowerk News) A single-atom-thick sheet of carbon known as graphene has remarkable properties on its own, but things can get even more interesting when you stack up multiple sheets. When two or more overlying sheets of graphene are sightly misaligned — twisted at certain angles relative to...
Plot thickens in hunt for ninth planet
Oct 05, 2023 (Nanowerk News) A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies. Researchers Harsh Mathur, a professor...
Observation of left and right at nanoscale with optical force
Oct 05, 2023 (Nanowerk News) A research group at the Institute for Molecular Science in Japan successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized light and detecting the optical force acting on a probe near the nanostructures....
Dragonfly eyes inspire new 3D microlens array processing technique
Oct 05, 2023 (Nanowerk News) Industry 4.0 requires simple solutions for complex functions. Optical sensors, such as pinhole cameras, can deliver a depth of focus and reasonable resolution, but they suffer from low intensity for reliable and fast imaging. This requires a long exposure time, which sacrifices fast imaging capability...
