A Nobel Laureate who co-created graphene has made another discovery that could turbocharge numerous futuristic applications, from smart contact lenses to rapid disease detection. Konstantin Novoselov, who won the 2010 Nobel Prize for Physics, is among a group of scientists behind the breakthrough. The team announced today that they’ve unearthed unique properties in two unusual compounds: rhenium diselenide and rhenium disulfide — aka ReSe2 and ReS2. The duo comes from the same family of 2D…

The first preliminary clinical trial of its kind on a handful of volunteers suggests our respiratory system can tolerate at least short-term exposure to low concentrations of graphene nanoparticles, new research shows.Graphene's impressive flexibility, exceptional strength and conductive properties mean it has potential in many fields from water filtration to condoms, supercomputers, and medical devices.Unfortunately we humans have an appalling track record of unintentionally poisoning ourselves and the life around us…

Empa researchers were also involved, such as molecular biologist Peter Wick, who was part of the…

The fractional quantum Hall effect has generally been seen under very high magnetic fields, but MIT physicists have now observed it in simple graphene. In a five-layer graphene/hexagonal boron nitride (hBN) moire superlattice, electrons (blue ball) interact with each other strongly and behave as if they are broken into fractional charges. Credit: Sampson Wilcox, RLEAn exotic electronic state observed by MIT physicists could enable more robust forms of quantum computing.The electron is the basic unit of electricity, as it…

Inhaling an ultra-pure form of the ‘wonder material’ graphene did not produce any short-term adverse effects on lung and cardiovascular function in a small group of healthy volunteers. The first-in-human study opens the door to developing a novel targeted drug delivery method to treat diseases such as cancer.The main goal of designing an optimized drug delivery system is to deliver therapeutic agents to diseased tissue in a controllable manner while producing few side effects on healthy tissue. Because of its chemical and…
