Silver-zinc battery chemistry is currently poised to move into the commercial marketplace for use in consumer electronics. This new silver-zinc battery chemistry uses the latest in advanced polymers, nano-technology, power electronics and processing methods to create a battery that surpasses other rechargeable batteries for notebook computers, mobile phone and consumer electronics applications.

The results of the first ever silver antimicrobial product trial in a nursing home environment, published in the British Journal of Community Nursing, reveal that levels of potentially deadly bacteria can be dramatically reduced using products treated with silver antimicrobial agents, creating cleaner and safer nursing homes for elderly residents across the UK.

"The use of copper - which is much cheaper and more abundant - as an alternative electrode material to silver would dramatically reduce the cost of these nanowire materials. Despite these advantages, copper nanowire conductors face a serious bottleneck for future practical use in flexible and stretchable optoelectronics: although they are nearly as conductive as silver, this conductivity is not stable. Researchers have now demonstrated conductive copper nanowire elastomer composites with ultrahigh performance stability against oxidation, bending, stretching, and twisting. This material offers a promising alternative as electrodes for flexible and stretchable optoelectronics. "

Copper prices tumbled to a five-week low Thursday on expectations that falling demand from China and a slowdown in the U.S. housing market will lead to a surplus of the metal. Other commodities traded mixed, with crude oil rebounding slightly and gold, silver and soybeans falling. Corn and wheat futures rose. China, the world's biggest buyer of copper, has been importing less of the metal since the completion of most major construction projects heading into the Beijing summer Olympics. Copper imports in June fell 20 percent compared to May, China's custom's agency said this month. As a result, stockpiles of the metal have swelled in Shanghai and London, helping drive down prices.

ScienceDaily (Sep. 9, 2008) - Deposits of undiscovered copper, molybdenum, gold and silver may be present in the Andes Mountains of South America, according to a new scientific assessment

Applied Nanotech Holdings Inc announced that its subsidiary, Applied Nanotech Inc (ANI), established a strategic development program with Optomec, Inc, a provider of printed electronics for solar, display, electronic packaging and flexible electronics applications. As a part of the commitment, ANI will install a dedicated Optomec M3D aerosol jet printer at its facilities in order to adapt its copper ink to Optomec's patented ultra high resolution printing technology. By utilizing ANI's copper ink, the Optomec printer will offer the solar, display, flexible circuit and PCB manufacturers contact-free deposition of high quality, low cost metal lines, the companies said. According to the companies, the Optomec printing solution is able to produce much finer lines than is currently possible with traditional screen printing and inkjet printing equipment. The combined ANI/Optomec copper ink printing solution will provide an alternative to silver inks facilitating lower cost, coupled with the promise of higher reliability. Furthermore, ANI's copper inks do not require expensive vacuum installation or inert gas environment lowering the cost of the capital for manufacturing equipment.

Thinking of throwing out your old cell phone? Think again. Maybe you should mine it first for gold, silver, copper and a host of other metals embedded in the electronics -- many of which are enjoying near-record prices.

Part of the growing trend for nearly every electronic device to be able to communicate with others, smart grid and advanced metering startup Trilliant has taken $40 million in its first official venture funding.\n\nTrilliant, like competitors Ambient, Silver Spring Networks, SmartSynch and others, makes wireless communication devices for utility meters. When enough are present in an area, they can form a mesh network capable of communicating moment-to-moment use information back to utilities, and to the homes and businesses they're installed within. (Some can also communicate via hardwired connections.)\n\nThe company is one of the oldest to try to tackle the problem. I covered it in more depth in June. The problem with looking at the field is that, at first glance, all the contenders seem to be pretty much identical; broadly speaking, each is approaching the same problem, that of trying to get more information about usage to consumers and utilities, in more or less the same way.

BOSTON - There's gold in the sea floor. Silver, copper, zinc and lead, too. The problem is, it's a mile or two underwater and encased in massive mineral deposits that layer a dark, mysterious world. But new technology and worldwide demand have combined to make mining for these metals economically feasible for the first time. A breakthrough project is moving forward in New Guinea, and new rules to govern deep ocean mining will be set by an international authority this spring.
