Nanogenerator provides continuous power by harvesting energy from the environment
Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow. view more (2007-04-06)
Cancer cells forming blood vessels send their copper to the edge
New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source. view more (2007-02-28)
Graphene nanoelectronics: Making tomorrow's computers from a pencil trace
A key discovery at Rensselaer Polytechnic Institute could help advance the role of graphene as a possible heir to copper and silicon in nanoelectronics. view more (2007-07-24)
First Direct Observations of Spinons and Holons
Working at the Advanced Light Source (ALS) of the U.S. Department of Energy's Lawrence Berkeley National Laboratory, a team of researchers has observed the theoretical prediction of electron "spin-charge separation" in a one-dimensional solid. view more (2006-07-17)
New nano-method may help compress computer memory
A team of chemists at Brown University have devised a simple way to synthesize iron-platinum nanorods and nanowires while controlling both size and composition. Nanorods with uniform shape and magnetic alignment are one key to the next generation of high-density information storage, but have been difficult to make in bulk. view more (2007-06-25)
Researchers push transmission rate of copper cables
You may not be able to get blood out of a turnip, but according to Penn State engineers, you can increase the data transmission of Category-7 copper cables used to connect computers to each other and the Internet. view more (2007-11-15)
Feeling the Heat: Berkeley Researchers Make Thermoelectric Breakthrough in Silicon Nanowires
Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley. view more (2008-01-11)
Thioethers synthesis process
Although today there exists a number of methods for the synthesis of organic molecules (the main components of certain medicines, foods, additives, paints, fabrics, liquid crystals, etc.), in most cases toxic reagents and solvents have to be used. view more (2007-04-03)
Faster computers, electronic devices possible after scientists create large-area graphene on copper
The creation of large-area graphene using copper may enable the manufacture of new graphene-based devices that meet the scaling requirements of the semiconductor industry, leading to faster computers and electronics, according to a team of scientists and engineers at The University of Texas at Austin. view more (2009-05-08)
Metal composition hold key to identity of modern sculptures
How do you tell when, where and how a Picasso or a Matisse sculpture was cast? view more (2009-07-31)
A mysterious change in the wave properties of electrons
The electrons of a perfect metallic surface move like free waves in a plane. Nevertheless, if atomic barriers are inserted, this may restrict their movement in one dimension, forming stationary waves such as those on the water surface in a bucket. view more (2004-09-30)
Remarkable new clothing may someday power your iPod
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users. view more (2008-02-14)
Paper electrified by copper particles
The Polymer Chemistry Research Group at the University of Helsinki, Finland, has succeeded in producing nano-sized metallic copper particles. view more (2009-03-16)
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. view more (2009-03-05)
Learning from copper
Video conferencing is on the rise. But the diverse options for the transmission of images and sound may be confusing. Thanks to SDSL, the project "digital classroom at the sickbed" shows how maximum performance is obtained using the existing copper wire infrastructure. Whatever the OECD Program for International Students Assessment might say,... view more... (2002-03-05)
Clues to African archaeology found in lead isotopes
Microscopic specs of lead are offering clues about the enormous cultural changes that swept across northern Africa a thousand years ago. view more (2006-03-27)
High-temperature superconductors: magnetic glue may be the clue
Striking pictures of magnetic waves inside advanced ceramics may be the clue to understanding how they can transmit electricity without losing energy, according to results obtained by two teams of scientists using the UK's world-leading ISIS neutron source in Oxfordshire and published this week in the journal Nature. The ceramics, known as... view more... (2004-06-02)
UCLA, Italian chemists move closer to solving Lou Gehrig's disease mystery
Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning. view more (2007-06-28)
Researchers probe health and safety impacts of nanotechnology
University of Florida engineering student Maria Palazuelos is working on nanotechnology, but she's not seeking a better sunscreen, tougher golf club or other product — the focus of many engineers in the field. view more (2007-01-31)
Capture of nanomagnetic 'fingerprints' a boost for next-generation information storage media
In the race to develop the next generation of storage and recording media, a major hurdle has been the difficulty of studying the tiny magnetic structures that will serve as their building blocks. view more (2009-01-29)
