Understanding electron transport in graphene nanoribbons

Graphene is a modern wonder material possessing unique properties of strength, flexibility and conductivity whilst being abundant and remarkably cheap to produce, lending it to a multitude of useful applications — especially true when these 2D atom-thick sheets of carbon are split into narrow strips known as Graphene Nanoribbons (GNRs). New research published in EPJ…

Stanford technology predicts the slow death of lithium-ion batteries

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it’s next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to manage charge levels wisely and…

Memory in a metal, enabled by quantum geometry

The emergence of artificial intelligence and machine learning techniques is changing the world dramatically with novel applications such as internet of things, autonomous vehicles, real-time imaging processing and big data analytics in healthcare. In 2020, the global data volume is estimated to reach 44 Zettabytes, and it will continue to grow beyond the current capacity…

Microscopic robots ‘walk’ thanks to laser tech

A Cornell University-led collaboration has created the first microscopic robots that incorporate semiconductor components, allowing them to be controlled — and made to walk — with standard electronic signals. These robots, roughly the size of paramecium, provide a template for building even more complex versions that utilize silicon-based intelligence, can be mass produced, and may…

Artificial materials for more efficient electronics

We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like. Today’s silicon-based electronics, however, consume a substantial and ever-increasing share of the world’s energy. A number of researchers are exploring the properties of materials that are more complex…
