Graphene-based Nano-antennas Could Enable Networks Of Tiny Machines
2013-12-12 18:00:25

Georgia Institute of Technology Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there's been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components. With antennas made from conventional materials like copper, communication between low-power nanomachines would be virtually impossible. But by taking advantage of the unique...

New findings could enhance stabilizing or destabilizing nanoparticles, depending on their uses University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important, or to design them so they readily condense into thin films for such things as inks or...

Scientists: Coal Is Better, Cheaper For Making Graphene Quantum Dots
2013-12-06 16:55:31

Brett Smith for redOrbit.com – Your Universe Online A team of scientists from Rice University has found a way to use coal as a source of graphene quantum dots (GQD), tiny fluorescent particles that could be used in medical imaging and photovoltaic applications – according to a new report in Nature Communications. The use of coal to make GQDs would be much cheaper than conventional means, which are expensive and only produce small quantities. “We wanted to see what’s there in...

Huge Grains Of Copper Promote Better Graphene Growth

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...

John P. Millis, PhD for redOrbit.com - Your Universe Online Although the name sounds like something out of a science fiction novel, nanoparticles are nothing more than tiny fragments of matter that are typically less than 100 nanometers in diameter – roughly one-thousandth the thickness of a sheet of paper. Despite their size, however, they can pose a significant health risk. Arising from various industrial processes, some pollutants, and even volcanic activity, the small size of the...

Zero-Index MetaMaterial Holds Promise For Future Quantum Networks And Light Sources
2013-12-06 08:25:49

Lawrence Berkeley National Laboratory The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. While quantum technologies remain grist for science fiction, a team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley...

A new way to create safer nanotechnology apparatus has been patented by Contipro Biotech. (PRWEB) November 29, 2013 High-voltage nanofibre production, using very high voltages of up to 120,000 volts, is a principle that has been known for a long time. Naturally, there is inherently a high risk of injury if equipment operators handle the high voltage electrodes or created nano-material before the residual surface charge has been safely discharged. Until now, hand-operated external grounded...

Nanomedicine May One Day Be Delivered Orally
2013-11-28 04:43:35

redOrbit Staff & Wire Reports - Your Universe Online Researchers from MIT and Brigham and Women's Hospital (BWH) have developed a new type of nanoparticle that can be absorbed through the digestive tract, bringing the cutting-edge treatment method one-step closer to being administered orally instead of through injections. While drugs delivered by nanoparticles could help treat cancer, diabetes and several other types of disease, the fact that these particles currently have to be...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
