Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics or spintronics, but getting them to perform consistently has proven difficult. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a data-driven approach that identifies and models key synthesis parameters to optimize their performance.

A research team from Hiroshima University, Hiroshima, Japan, the University of Colorado, Boulder, USA, and other collaborators has demonstrated that space-time crystals—exotic structures that, under external drive, loop endlessly through both space and time—can be created using everyday liquid-crystal materials.

A research team has identified a mechanism that could help overcome the efficiency limitations of thermoelectric devices that convert waste heat into electricity using a “hollow silicon nanotube” structure. The findings were published in Nano Energy, a leading international academic journal in the field of energy and nanotechnology.

Researchers at Carnegie Mellon University, in collaboration with Stanford and Purdue, have demonstrated a powerful new way to control heat at the nanoscale. Using carefully engineered metamaterials — microscopic gold patterns on thin membranes — they achieved up to four times more heat transfer across a tiny gap compared to conventional setups.

Rice University researchers have developed a simple new technique to create nanoscale patterns on hard chip materials at room temperature. By layering anisotropic alpha-molybdenum trioxide crystals on silica and exposing them to an electron beam, the team induced controlled stress that forms highly ordered nanoscale wrinkles or ripples.

A sheet of twisted carbon nanotubes has revealed a hidden talent scientists suspected for decades but had never managed to measure.
