Physikalisch-Technische Bundesanstalt (PTB) New production method broadens the perspectives for an improved use of the "magic material" - many different forms are possible Graphene, a crystal composed of only one layer of carbon atoms arranged in a regular hexagon, is regarded as a material which is believed to be capable of performing miracles, in particular in the fields of electronics, sensor technology and display technology, but also in metrology. Only four years after the first...

The unique properties of graphene such as its incredible strength and, at the same time, its little weight have raised high expectations in modern material science. Graphene, a two-dimensional crystal of carbon atoms packed in a honeycomb structure, has been in the focus of intensive research which led to a Nobel Prize of Physics in 2010. One major challenge is to successfully integrate graphene into the established metal-silicide technology. Scientists from the University of Vienna and their...

New Material Created At Rice University With Graphene Oxide Flakes

Rice University Large flakes of graphene oxide are the essential ingredient in a new recipe for robust carbon fiber created at Rice University. The fiber spun at Rice is unique for the strength of its knots. Most fibers are most likely to snap under tension at the knot, but Rice's fiber demonstrates what the researchers refer to as "100 percent knot efficiency," where the fiber is as likely to break anywhere along its length as at the knot. The new work from the Rice lab of chemist...

Strength Of CVD Graphene Revealed In New Study

Columbia University In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice. Graphene consists...

Tweaking graphene chemical sensors may open up many applications Researchers have discovered a technique for controlling the sensitivity of graphene chemical sensors. The sensors, made of an insulating base coated with a graphene sheet--a single-atom-thick layer of carbon--are already so sensitive that they can detect an individual molecule of gas. But manipulating the chemical properties of the insulating layer, without altering the graphene layer, may yet improve their ability to...

Scientists have taken inspiration from one of the oldest natural materials to exploit the extraordinary qualities of graphene, a material set to revolutionize fields from computers and batteries to composite materials. Published today in Nature Communications, a Monash University study led by Professor Dan Li has established, for the first time, an effective way of forming graphene, which normally exists in very thin layers, into useful three-dimensional forms by mirroring the structure of...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
