Scientists Find Why Conductance of Nanowires Vary
A Georgia Tech physics group has discovered how and why the electrical conductance of metal nanowires changes as their length varies. view more (2007-02-06)
Study of the corrosive effects of water
As is known, corrosion is defined as the destruction of a material under chemical or electrochemical action by its surrounding environment. The reactions and transformations involved in this corrosion are due to the thermodynamic instability in the materials of which the surrounding environment is made up, giving rise to products with properties... view more...

Secrets behind high temperature superconductors revealed
Scientists from Queen Mary, University of London and the University of Fribourg (Switzerland) have found evidence that magnetism is involved in the mechanism behind high temperature superconductivity. view more (2009-02-23)
Materials Today (February issue) Molecular electronics: What is it? How will it be applied in the future?
Introducing molecular electronics "In the natural world, molecules are used for many purposes. Using molecule-based materials for electronics, sensing, and optoelectronics is a new endeavor, called molecular electronics, and the subject both of riveting new research, and substantial popular press interest," says Mark Ratner. As one of... view more... (2002-02-06)
Why do polar foxes disappear?
The polar foxes inhabit the Commandor Islands. Due to isolation, the polar foxes of each island differ from the ones inhabiting the mainland and even from the neighbors populating other islands of the archipelago. As a matter of fact, each island is populated by an individual polar fox subspecies. Isolated populations have always been of interest... view more... (2002-10-11)
Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy. view more (2008-02-14)
Low-cost solution processing method developed for CIGS-based solar cells
Though the solar industry today predominately produces solar panels made from crystalline silicon, they remain relatively expensive to make. view more (2009-07-08)
UMass Amherst Researchers Discover That Microbes Can Produce Miniature Electrical Wires†
Researchers at the University of Massachusetts Amherst have discovered a tiny biological structure that is highly electrically conductive. This breakthrough helps describe how microorganisms can clean up groundwater and produce electricity from renewable resources. It may also have applications in the emerging field of nanotechnology, which... view more... (2005-06-24)
A new idea for how anti-aging products delay ripening of fruit and wilting of flowers
When plants encounter ethylene, a gas they also produce naturally as a hormone, the result is softening and ripening in the case of fruit, and wilting and fading in the case of flowers - all of which ethylene promotes. view more (2008-05-05)
Slimmer, Stickier Nanorods Give Boost to 3-D Computer Chips
Researchers at Rensselaer Polytechnic Institute have developed a new technique for growing slimmer copper nanorods, a key step for advancing integrated 3-D chip technology. view more (2009-03-18)

Rice lab finds molecular clues to Wilson disease
Using a combination of computer simulations and cutting-edge lab experiments, physical biochemists at Rice University have discovered how a small genetic mutation -- which is known to cause Wilson disease -- subtly changes the structure of a large, complex protein that the body uses to keep copper from building up to toxic levels. view more (2008-08-20)
Safer, denser acetylene storage in an organic framework
The century-old challenge of transporting acetylene may have been solved in principle by a team of scientists working at the National Institute of Standards and Technology (NIST). view more (2009-08-27)
