Graphene/National Graphene Institute/Manchester group discovers new family of quasiparticles in graphene-based materials

Findings to help achieve Holy Grail of 2D materials – superfast electronic devices. A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at The University of Manchester have discovered and characterised a new family of quasiparticles named ‘Brown-Zak fermions’ in graphene-based superlattices.

The team achieved this breakthrough by aligning the atomic lattice of a graphene layer to that of an insulating boron nitride sheet, dramatically changing the properties of the graphene sheet.

The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of a fractal pattern known as the Hofstadter’s bu...

Electronic shirts that keep the wearer comfortably warm or cool, as well as medical fabrics that deliver drugs, monitor the condition of a wound and perform other tasks, may one day be manufactured more efficiently thanks to a key advance by Oregon State University researchers.

The breakthrough involves inkjet printing and materials with a crystal structure discovered nearly two centuries ago. The upshot is the ability to apply circuitry, with precision and at low processing temperatures, directly onto cloth — a promising potential solution to the longstanding tradeoff between performance and fabrication costs.

“Much effort has gone into integrating sensors, displays, power sources and logic circuits into various fabrics for the creation of we...
