Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often. A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this.
First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.
BOULDER, Colo. -- Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information
processor able to run any program allowed by quantum mechanics -- the rules governing the submicroscopic world -- using two quantum bits (qubits) of information.
Silicon nanowires are attracting significant attention from the electronics industry due to the drive for ever-smaller electronic devices, from cell phones to computers.
November 11, 2009 (Oakland, Calif.) -- High levels of workplace exposure to Bisphenol-A may increase the risk of reduced sexual function in men, according to a Kaiser Permanente study appearing in
In one sense, our hands define our humanity. Our opposable thumbs and our hands' unique structure allow us to write, paint, and play the piano.
EAST LANSING, Mich. -- Nature inspires technology for an engineer and an ecologist teamed up at Michigan State University.
A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means.
Electronic tools and technology applications for consumers can help improve health care processes, such as adherence to medication and clinical outcomes like smoking cessation, according to a repor
Could sustainable architecture address pollution, climate change and resource depletion by helping us build self-sufficient, off-grid, housing from "waste", including vehicle tires and metal drinks containers? That's the question researchers at the University of South Australia hope to answer in the International Journal of Sustainable Design.
In an effort to make graphene more useful in electronics applications, Kansas State University engineers made a golden discovery -- gold "snowflakes" on graphene.
Researchers analyzing the assembly of graphene (sheets of carbon only one atom thick) on a surface of iridium have found that the sheets grow by first forming tiny carbon domes. The discovery offers new insight into the growth of graphene layers and points the way to possible methods for assembling components of graphene-based computer circuits.
The National Institute of Standards and Technology (NIST) has unveiled a method for calibrating entire waveforms -- graphical shapes showing how electrical signals vary over time -- rather than just parts of waveforms as is current practice.
Although arsenic (As) occurs ubiquitously in the environment and has been used since its isolation in 1250 A.D in various fields such as medicine, metallurgy, agriculture and electronics, it is undoubtedly best known for its toxicity to both plants and animals. The toxic effects of arsenic in humans range from skin lesions to cancer of the brain, liver, kidney and stomach.
