Huge Grains Of Copper Promote Better Graphene Growth
2013-12-06 14:35:14

American Institute of Physics To technology insiders, graphene is a certified big deal. The one-atom thick carbon-based material elicits rhapsodic descriptions as the strongest, thinnest material known. It also is light, flexible, and able to conduct electricity as well as copper. Graphene-based electronics promise advances such as faster internet speeds, cheaper solar cells, novel sensors, space suits spun from graphene yarn, and more. Now a research team at the National Institute of...

University of Illinois researchers have developed a way to heal gaps in wires too small for even the world’s tiniest soldering iron. Led by electrical and computer engineering professor Joseph Lyding and graduate student Jae Won Do, the Illinois team published its results in the journal Nano Letters. Carbon nanotubes are like tiny hollow wires of carbon just 1 atom thick – similar to graphene but cylindrical. Researchers have been exploring using them as transistors instead of...

Condoms Made From Graphene

redOrbit Staff & Wire Reports - Your Universe Online The highly-touted wonder-material graphene won the Nobel Prize for its ability to revolutionize circuit boards, food packaging, and countless other products. Now, it has won another honor – a $100,000 grant from the Bill and Melinda Gates Foundation that will lead to the development of a new and improved condom. In actuality, that grant was awarded to the UK’s National Graphene Institute, a research facility at the University...

Study Shows Another Feature That Affects Electron Transport In Graphene
2013-11-21 16:27:26

University of Wisconsin - Milwaukee For all the promise of graphene as a material for next-generation electronics and quantum computing, scientists still don't know enough about this high-performance conductor to effectively control an electric current. Graphene, a one-atom-thick layer of carbon, conducts electricity so efficiently that the electrons are difficult to control. And control will be necessary before this wonder material can be used to make nanoscale transistors or other...

2-D Tin Could Be The Next Super Material

It’s not X-ray vision, but you could call it infrared vision. A University at Buffalo-led research team has developed a technique for “seeing through” a stack of graphene sheets to identify and describe the electronic properties of each individual sheet — even when the sheets are covering each other up. The method involves shooting a beam of infrared light at the stack, and measuring how the light wave's direction of oscillation changes as it bounces off the layers within. To...

Funds enable further development of specialized lithium-ion anode materials, which can be used to create full-scale, high-capacity batteries. Lansing, Mich. (PRWEB) November 20, 2013 XG Sciences, Inc. (XGS) announced today it has been awarded $1 million in funding from the U.S. Department of Energy (DOE) for continued development of its XG SiG™ high-energy lithium-ion battery materials. These new anode materials have demonstrated energy storage capacity of up to four times that of...

A team of Clemson University physicists consisting of nanomaterial scientists Apparao Rao and Ramakrishna Podila and thermoelectricians Terry Tritt, Jian He and Pooja Puneet worked synergistically through the newly established Clemson Nanomaterials Center to develop a novel technique of tailoring thermoelectric properties of n-type bismuth telluride for high thermoelectric performance. Their findings were published in journal Scientific Reports. The current US energy economy and...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
