Laser-treated cork absorbs oil for carbon-neutral ocean cleanup

Tue, 04/23/2024 - 8:31am
Researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material's light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling. The laser treatments not only help to better absorb oil, but also work to keep water out.

Perfecting the view on a crystal's imperfection

Tue, 04/23/2024 - 8:30am
Hexagonal boron nitride (hBN) has gained widespread attention and application across various quantum fields and technologies because it contains single-photon emmiters (SPEs), along with a layered structure that is easy to manipulation. The precise mechanisms governing the development and function of SPEs within hBN have remained elusive. Now, a new study reveals significant insights into the properties of hBN, offering a solution to discrepancies in previous research on the proposed origins of SPEs within the material.

This alloy is kinky

Mon, 04/22/2024 - 9:07am
Researchers have uncovered a remarkable metal alloy that won t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy keeps its shape and resists cracking at both high and low temperature extremes, making it potentially suitable for demanding applications like high-efficiency aerospace engines.

Magnetic with a pinch of hydrogen

Mon, 04/22/2024 - 9:06am
Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the magnetic states of these materials well enough. A research team is now presenting an innovative idea that could overcome this shortcoming -- by allowing the 2D layer to react with hydrogen.
