For next-generation semiconductors, 2D tops 3D

Researchers have developed a memory device using a two-dimensional layered-structure material, unlocking the possibility of commercializing the next-generation memory device that can be stably operated at a low power.

Tiny bubbles make a quantum leap

Using sophisticated optical microscopy techniques, engineers demonstrate that sufficient strain in 2D material can yield single-photon emitters, key to quantum technologies and future photonic circuitry.

Cherned up to the maximum

In topological materials, electrons can display behaviour that is fundamentally different from that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached in a real material.

Liquid crystals create easy-to-read, color-changing sensors

Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile's skin a rainbow of colors. Inspired by this, scientists have developed a way to stretch and strain liquid crystals to generate different colors.

'Nanocage' tool untangles (molecular) spaghetti

A team of scientists have invented a new tool that can catch and straighten out molecule-sized tangles of polymers - whether made of protein or plastic. This tool, that works a bit like pulling a wad of thread through a needle hole, opens a new way to create custom materials that have never been made before.
