Physicists Discover How To Change The Crystal Structure Of Graphene
2014-05-01 03:38:14

Daniel Stolte, University of Arizona A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology. Graphene consists of extremely thin sheets of graphite: when writing with a pencil, graphene sheets slough off the pencil's graphite...

Not Everything About Graphene Is Good

Sean Nealon, University of California, Riverside Material that could change electronics industry is shown to be very mobile in water and likely to cause negative environmental impacts if spilled In a first-of-its-kind study of how a material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobile in lakes or streams and therefore likely to...

Graphene Is Only As Strong As Its Weakest Link

Mike Williams, Rice University Rice, Georgia Tech experiments determine real-world limits of two-dimensional carbon There is no disputing graphene is strong. But new research by Rice University and the Georgia Institute of Technology should prompt manufacturers to look a little deeper as they consider the miracle material for applications. The atom-thick sheet of carbon discovered this century is touted not just for its electrical properties but also for its physical strength and...

Creating Nanowires Only Three Atoms Wide With An Electron Beam
2014-04-28 03:12:14

David Salisbury, Vanderbilt University Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today's integrated circuits. Lin's achievement is described in an article published online...

Graphene has possible uses in brain cancer treatment, neuroregeneration, functional neurosurgery, and more The development of graphene—a highly advanced metamaterial with many unique and varied properties—may lead to exciting new applications in the diagnosis and treatment of neurological diseases, according to a report in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of...

How Can Graphene Sheets Be Utilized In Real-world Devices?
2014-04-25 03:15:43

National Science Foundation Fundamental research in phonon scattering helps researchers design graphene materials for applications Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material--strong, light, nearly transparent and an excellent conductor of electricity and heat--and it very well may be. But a number of practical challenges must be overcome before it can emerge as a replacement for silicon and other materials in microprocessors and...

Graphene-Based Spaser Could Lead To Printable Smartphones
2014-04-25 04:23:53

Brett Smith for redOrbit.com - Your Universe Online According to a new report in the journal ACS Nano, a team of Australian engineers have modelled a kind of laser called a “spaser” that would allow for the creation of smartphones so small and flexible – they could be printed on a t-shirt. Simply put, spasers are nanoscale lasers that emit a beam of light via the vibration of free electrons, as opposed to the relatively space-consuming beam of a traditional laser. While spasers,...
