New work shows that superconductivity in twisted bilayer graphene can exist away from the magic angle

New study by Caltech shows that superconductivity in twisted bilayer graphene can exist away from the magic angle when coupled to a two-dimensional semiconductorIn 2018, researchers made the surprising discovery that when you layer two sheets of single-atom-thick...

Rice University researchers use sticky tape to improve batteries

Rice University scientists led by Prof. James Tour have turned adhesive tape into a silicon oxide film (mixed with laser-induced graphene) which replaces troublesome anodes in lithium metal batteries.At left, a copper current collector with a laser-induced silicon...

International team discovers “mediator atoms” that help graphene self-heal

An international team of researchers in Korea, the UK, Japan, the US and France recently shed light on the mysterious ability of graphene (and other carbon materials) to change its structure and even self-heal defects, by showing that fast-moving carbon atoms catalyze...

New graphene nanoribbons could enable smaller electronic devices

A new collaborative study has reported a 17-carbon wide graphene nanoribbon and found that it has the tiniest bandgap observed so far among familiar graphene nanoribbons prepared through a bottom-up approach.(a) Bottom-up synthesis scheme of 17-AGNR on Au(111), (b)...

Doped graphene shows promise for sodium-ion batteries

Scientists at EPFL have recently published a research that could open up new pathways to boosting the capacity of sodium-ion batteries. “Lithium is becoming a critical material as it is used extensively in cell-phones and car batteries, while, in principle,...
