Novel quantum effect discovered in naturally occurring graphene

Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of ...

Graphene: 'Miracle material' singled out for COVID conspiracies

Graphene, a Nobel Prize-awarded material with promising applications for greener energy and nanomedicine, has been the topic of much disinformation by coronavirus anti-vaxxers claiming it can be used to "magnetize" and "control" ...

Smallest cavity for light realized by graphene plasmons

Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from ...

On-demand control of terahertz and infrared waves

The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics. A theory ...

Graphene's effects on the lungs

Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa and the Adolphe Merkle Institute ...

A most singular nano-imaging technique (Update)

Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven ...

Quasi-particle swap between graphene layers

Belgian scientists have used a particle physics theory to describe the behaviour of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In a paper published ...
