[ Twisted graphene could power a new generation of superconducting electronics ]

In 2018, a group of researchers at the Massachusetts Institute of Technology (MIT) pulled off a dazzling materials science magic trick. They stacked two microscopic cards of graphene’sheets of carbon one atom thick’and twisted one ever so slightly. Applying an electric field transformed the stack from a conductor to an insulator and then, suddenly, into a superconductor: a material that frictionlessly conducts electricity. Dozens of labs leapt into the newly born field of ‘twistronics,’ hoping to conjure up novel electronic devices without the hassles of fusing together chemically different materials.

Energy scavenging nanogenerator finds power all around us

“These so-called triboelectric nanogenerators (or TENGs) can be made at low cost in different configurations, making them suitable for driving small electronics such as personal electronics (mobile phones), biomechanics devices (pacemakers), sensors (temperature/pressure/chemical sensors), and more,” says Professor Youhong Tang, from Flinders University’s College of Science and Engineering.

Further research aims to further develop this renewable form of energy harvesting by designing simple fabrication from cheap and sustainable materials, with high efficiency.
