Breakthrough in LED construction increases efficiency by 57 percent

With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent. Read More

Shellfish proteins inspire waterproof wonderglue

Clingy barnacles might be something of a nuisance for seafarers, but these stubborn shellfish and their relatives could hold the key to a new breed of sticky materials. Engineers from MIT have created waterproof adhesives based on the proteins that give these creatures such qualities, a development that could one day be used in ship repairs or medical applications.

Buckyballs and diamondoids combined to create molecule-sized diode

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity in only the one direction. In essence, a rectifier diode, but one so small that it may one day help replace much bulkier diodes and other semiconductors found on today's integrated circuits to produce incredibly compact, super-fast electronic devices.

Organs-on-Chips emulate human organs, could replace animals in tests

The search for more efficient tests of pharmaceuticals without animal models is taking a stride forward, with a new technology being developed in the US called Organs-on-Chips. The new miniature platform and software, which mimic the mechanical and molecular characteristics of human organs, were developed by bioengineers from the Wyss Institute for Biologically Inspired Engineering at Harvard University.

Stable lithium anode may triple battery efficiency

Stanford University researchers claim to have created the first stable pure lithium anode in a working battery by using carbon nanospheres as a protective sheath to guard against degradation. As a result, the researchers predict that commercial developments may eventually result in anything up to a quadrupling of battery life in the not-too-distant future. Read More

CoeLux skylight brings "sunlight" to windowless spaces

For residents living in the north, where sunlight can be a rare commodity during the winter, a psychological condition known as Seasonal Affective Disorder is a very real problem. Light therapy is one way to shake off the winter blues, and although artificial lighting solutions do exist, they are generally available as simple variations on traditional desk lamps. An Italian designer has developed CoeLux, a unique system that delivers artificial light through an intelligent false skylight. Read More

Researchers create flexible wires that could double as batteries

We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.

MagnetoSperm could find use in drug delivery, or even baby-making

When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm. Read More
