Lithium-ion batteries inspired by snail shells could prove longer-lasting

By - February 11, 2015 3 Pictures
In an ongoing effort to improve the performance of lithium-ion batteries, scientists have looked to the techniques that snails use to control the growth of their shells. This biological inspiration, combined with a peptide found to bind very effectively with materials used to make cathodes, has potential for making lighter and longer-lasting batteries. Read More

New electronic technique promises to double optical fiber communications reach

By - February 10, 2015 3 Pictures
A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. Read More

V-One conductive ink printer aims to short-circuit electronic prototyping

By - February 10, 2015 9 Pictures
In designing and prototyping electronic circuit boards there is no quick or simple way to produce results. Many hours of design and development need to be expended on prototype layouts along with masking, etching, and populating those boards with components. Even after all of this, just one simple layout mistake can ruin all of your work and you have to go through the entire process again. The Voltera V-One aims to change all of that with the promise of a one button, conductive ink printing system solely designed to reduce the effort in rapid, small run hardware prototyping. Read More

Optical antenna may allow LEDs to replace lasers in host of devices

By - February 4, 2015 3 Pictures
By applying 120 year old radio frequency antenna theory to the much newer field of photonics, researchers at Lawrence Berkeley National Laboratory claim to have produced a prototype optical antenna that increases the intensity of emission from a nanorod light source by more than 115 times. This technique may offer the opportunity to replace power-hungry lasers in short-range optical communications devices with enhanced low-power LEDs. Read More

Energizer's "EcoAdvanced" batteries are partially made from recycled cells

By - February 4, 2015
Energizer has announced a new line of high-performance AA and AAA alkaline batteries that are in part made by recycling old cells, in what's claimed to be an industry first. Although currently only four percent of the battery comes from recovered materials, the plan for the company is to grow that percentage tenfold over the next 10 years and eventually use recycled materials in all its future cells.

Skin-applied foil could give people a sense of "magnetoception"

By - February 3, 2015 4 Pictures
How would you like to be able to sense magnetic fields? It could come in handy, given that some animals navigate and maintain their spatial orientation by doing so. Well, we've now come one step closer to humans having that ability, too. Scientists from Germany's Leibniz Institute for Solid State and Materials Research, along with colleagues from the University of Tokyo and Osaka University, have developed a thin, flexible magnetoresistive sensory foil that can be applied to a person's own natural skin.

New technique could produce the ideal light-absorbing material for solar cells

By - February 3, 2015
Solar cell efficiency has made significant strides in recent times, but cells are still far from their maximum theoretical efficiency, and part of the reason is that the semiconductors we use to build them don’t have ideal electrical properties. Researchers at Northwestern University have now found a way to tweak an important electrical feature of transition metal oxides, compounds commonly used as semiconductors, to build the optimal light-absorbing material for solar cells, lasers and photoelectrochemical cells.
