Quest For ‘Invisibility Cloak’ Remains Elusive, It So Appears
2013-11-12 07:43:18

redOrbit Staff & Wire Reports - Your Universe Online Limitations in current cloaking technology allow objects to be temporarily concealed at only narrow wavelengths of light or microwaves, while many newer designs actually make things more visible, experts at the University of Texas acknowledged on Monday. Current cloaking devices, which are made of a variety of materials such as planes of glass, work by bending light around objects to make them temporarily invisible. Scientists...

Wireless Device Turns 'Lost' Energy Into Electric Power
2013-11-07 14:28:49

Duke University Metamaterial cells designed by Duke engineers provide electric power as efficiently as solar panels Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other...

Nanoparticles filled with chemotherapeutic drugs can kill drug-resistant breast cancer cells, according to a study published in the scientific journal Biomaterials. Nanoparticles are just as small, or even smaller, than many blood proteins. They can therefore pass through the walls of healthy and sick cells, which make them interesting carriers of drugs against cancer and other diseases. In the present study, researchers from Karolinska Institutet have shown that nanoparticles made from...

Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor. The results were developed in close collaboration with the Universities of Bochum, Paderborn and Lyon and have been published in the magazine Physical Review X....

An international team of researchers has used pioneering electron microscopy techniques to discover an important mechanism behind the reaction of metallic nanoparticles with the environment. Crucially, the research led by the University of York and reported in Nature Materials, shows that oxidation of metals - the process that describes, for example, how iron reacts with oxygen, in the presence of water, to form rust - proceeds much more rapidly in nanoparticles than at the macroscopic...

New Device Architecture For 2D Materials Developed Making Electrical Contact From The 1D Edge
2013-10-31 14:05:13

Columbia University Columbia Engineering researchers have experimentally demonstrated for the first time that it is possible to electrically contact an atomically thin two-dimensional (2D) material only along its one-dimensional (1D) edge, rather than contacting it from the top, which has been the conventional approach. With this new contact architecture, they have developed a new assembly technique for layered materials that prevents contamination at the interfaces, and, using graphene as...

The updated Nanotechnology Consumer Products Inventory now contains 1,628 consumer products that have been introduced to the market since 2005, representing a 24 percent increase since the last update in 2010. In addition to finding new products introduced to the market, the newly re-launched inventory seeks to address scientific uncertainty with contributions from those involved with nanomaterials production, use, and analysis. WASHINGTON (PRWEB) October 29, 2013 The updated...


Word of the Day
cacodemon
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
