Electronic tattoos promise to help people monitor health in all kinds of ways, from heart rates to blood sugar and more. Now here's one that can monitor your tooth-brushing skills. A tooth-based sensor can detect different types bacteria in your saliva that can cause a variety of health problems.
Researchers at Stanford and the DOE's SLAC National Accelerator Lab have created a new kind of graphene that promises the first-ever "designer electrons" that can be custom tuned to exhibit exotic properties. This "molecular graphene" could lead to whole new types of materials with new electrical properties, which in turn could spawn whole new kinds of devices.
The way electrons conduct their business is central to just about everything we consider modern electronic technology.
Nanotechnology as a discipline is bleeding-edge cool, but so often we hear more about its amazing potential than its practical application. So it's always refreshing to catch wind of a story like this: Researchers at Rensselaer Polytechnic Institute in New York have developed and demonstrated a small, relatively inexpensive, and reusable sensor made of graphene foam that far outperforms commercial gas sensors on the market today and could lead to better explosives detectors and environmental sensors in the very near future.
Next time you’re inhaling an entire box of Girl Scout shortbread cookies, just think of the potential you’re wasting: a full $15 billion worth of graphene. At least, that’s the estimate given by a team of Rice University researchers working on a dare.
Researchers at the University of Technology Sydney have created a new material that is lighter, less dense, harder, and stronger than steel. But this material isn’t one of those breakthroughs that only sounds good on paper. It is paper, and it could be a game-changer for materials science if it can live up to researchers’ hopes.
One of the most promising materials in science could answer some questions about one of the most elusive particles in the universe, according to a new paper. A trio of Spanish physicists believes that graphene, that simple, special Nobel-winning stuff, could provide some key insights into the behavior of the Higgs boson.
Graphene is widely regarded as the electronics material of the future, but in an article published over the weekend in the journal Nature Nanotechnology, a group from EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES) describes how the abundant mineral molybdenite (MoS2) is a very effective semiconductor with advantages over both graphene and silicon. The discovery could allow for transistors that are smaller and orders of magnitude more efficient.
A graphene sheet stretched among three electrodes is the tiniest device to directly receive radio signals, researchers say. Nanoscale radio receivers could be useful for sensing, physics studies and radio signal processing, which could even make them useful for mobile phones.
The Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics today to University of Manchester professors Andre Geim and Konstantin Novoselov for their work isolating graphene from graphite and identifying its behavior. Graphene, a one-atom thick sheet of carbon, is the thinnest, strongest material ever discovered. It conducts heat and electricity, and despite being one atom thick, is so dense even helium cannot pass through it. As the Swedish Academy of Sciences said in the Nobel Prize announcement: "Carbon, the basis of all known life on earth, has surprised us once again."
Scientists at the University of Maryland at College Park have managed to clock a floating piece of graphene at an unbelievable 60 million rpm, far faster than any other macroscopic object yet measured. Even crazier: Given graphene's strength, one of the scientists says that may only be a thousandth of its possible top speed.
