Ever since its discovery in 2004 graphene has been considered a wonder material, and researchers have great expectations for it. The material is 300 times stronger than steel, and a million times thinner than a human hair. It is also the world’s best conductor of electricity and heat. These features can positively impact many applications, such as making more powerful batteries, more efficient solar panels, and faster computers. Although, it is tough to manipulate graphene beyond it's two-dimensional form.
A recent study published in Science Advances reveals a method to manipulate graphene to create the world’s most light-absorbent material for its weight. The material is nanometer-thin and will facilitate futuristic applications such as 'smart wallpaper', which could produce electricity from waste heat or light, and power many applications within the increasing 'internet of things'.
An international research group led by physicists at the University of Arkansas created magnetic two-dimensional metal in an artificial oxide material that could be used to make better transistors.
Scientists at the University of Southampton have made a major step forward in the development of digital data storage that is capable of surviving for billions of years.
Graphene combines transparency, electrical conductivity, and high durability into a one-atom-thick sheet of carbon. Even though graphene is known to be a "wonder material," it has still not been successful in industrial and commercial processes and products.
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combined two different ultrathin semiconductors — each just one layer of atoms thick and roughly 100,000 times thinner than a human hair — to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team, led by Boeing Distinguished Associate Professor Xiaodong Xu, announced its findings in a paper published Feb. 12 in the journal Science.
After more than half a decade of speculation, fabrication, modeling and testing, an international team of researchers led by Drexel University’s Yury Gogotsi, PhD , and Patrice Simon, PhD, of Paul Sabatier University in Toulouse, France, have confirmed that their process for making carbon films and micro-supercapacitors will allow microchips and their power sources to become one and the same.
Physicists at the Technical University of Munich (TUM) have developed a nanolaser, a thousand times thinner than a human hair. Thanks to an ingenious process, the nanowire lasers grow right on a silicon chip, making it possible to produce high-performance photonic components cost-effectively. This will pave the way for fast and efficient data processing with light in the future.
Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have found a simple new way to produce nanoscale wires that can serve as tiny, tunable lasers.
Photographers capture high-speed motion using cameras with a split-second shutter speed feature. Similar to these photographers, scientists examine very small materials using specific instruments, which are capable of seeing changes that occur in the blink of an eye.
