Energy-saving data glasses

Thu, 2016-11-03 18:39
Data glasses mirror information to the eye without interfering with the wearer‘s vision, report researchers.

Adding hydrogen to graphene

Thu, 2016-11-03 18:38
Adding hydrogen to graphene could improve its future applicability in the semiconductor industry, when silicon leaves off. Researchers have recently gained further insight into this chemical reaction. These findings extend the knowledge of the fundamental chemistry of graphene and bring scientists perhaps closer to realizing new graphene-based materials.

Engineers develop new magnetic ink to print self-healing devices that heal in record time

Thu, 2016-11-03 00:05
A magnetic ink has been developed that can be used to make self-healing batteries, electrochemical sensors and wearable, textile-based electrical circuits.

Bioelectronics at the speed of life

Wed, 2016-11-02 23:51
With a microfabricated ion pump built from organic electronic components, ions can be sent to nerve or muscle cells at the speed of the nervous system and with a precision of a single cell, say scientists.

Heating up exotic topological insulators

Tue, 2016-11-01 20:16
Fashion is changing in the avant-garde world of next-generation computer component materials. Traditional semiconductors like silicon are releasing their last new lines. Exotic materials called topological insulators (TIs) are on their way in. And when it comes to cool, nitrogen is the new helium, say scientists.

Artificial muscles show more flex

Mon, 2016-10-31 22:19
Artificial muscles made significant gains when a literal twist in the development approach uncovered the tensile or stretchy abilities of polymer fibers once they were twisted and coiled into a spring-like geometry. In a similar manner to the powerful climbing tendrils of cucumber plants, the unique geometry gives the coil a flexing motion when fiber material shrinks a reaction that can be controlled with heat. Now, researchers have improved these tensile properties even further by focusing on the thermal properties of the polymer fiber and the molecular structure that makes best use of the chiral configuration.

When it comes to atomic-scale manufacturing, less really is more

Sat, 2016-10-29 01:51
Electrical currents can be now be switched on and off at the smallest conceivable scale enabling a new generation of 'green electronics' with the potential for great impact on the digital economy.

New technique reveals powerful, 'patchy' approach to nanoparticle synthesis

Fri, 2016-10-28 23:12
Patches of chain-like molecules placed across nanoscale particles can radically transform the optical, electronic, and magnetic properties of particle-based materials. Now, scientists have used cutting-edge electron tomography techniques—a process of 3D reconstructive imaging—to pinpoint the structure and composition of the polymer nano-patches.

Controlling the properties of matter in two-dimensional crystals

Thu, 2016-10-27 19:16
The discovery of chains of atoms in a two-dimensional crystal could help researchers control the properties of matter.

Next-generation smartphone battery inspired by the gut

Wed, 2016-10-26 19:57
A new prototype of a lithium-sulphur battery -- which could have five times the energy density of a typical lithium-ion battery -- overcomes one of the key hurdles preventing their commercial development by mimicking the structure of the cells which allow us to absorb nutrients.

Making silicon-germanium core fibers a reality

Tue, 2016-10-25 22:31
Glass fibers do everything from connecting us to the internet to enabling keyhole surgery by delivering light through medical devices such as endoscopes. But as versatile as today's fiber optics are, scientists around the world have been working to expand their capabilities by adding semiconductor core materials to the glass fibers. Now, researchers report that they have created glass fibers with single-crystal silicon-germanium cores.

Supersonic phenomena, the key to extremely low heat loss nano-electronics

Tue, 2016-10-25 21:22
Supersonic solitary waves in nano-electronics crystals show potentials for electric charge or matter transport and energy storage with extremely low heat dissipation, explain researchers.

A complete waste of energy

Tue, 2016-10-25 21:15
Americans waste up to $19 billion annually in electricity costs due to "vampire appliances," always-on digital devices in the home that suck power even when they are turned off. But now engineers have come up with a way to produce microscopic electronic switches for appliances and devices that can grow and dissolve wires inside the circuitry that instantly connect and disconnect electrical flow. With this technology, consumer products such as smartphones and computer laptops could run at least twice as long on a single battery charge, and newer all-digital appliances such as televisions and video game consoles could be much more power efficient.

Can the brain feel it? The world's smallest extracellular needle-electrodes

Tue, 2016-10-25 21:14
5-?m-diameter needle-electrodes on 1 mm × 1 mm block modules have now been developed by researchers. This tiny needle may help solve the mysteries of the brain and facilitate the development of a brain-machine interface.

Controlling ultrasound with 3-D printed devices

Tue, 2016-10-25 20:33
Ultrasound is more than sound. Obstetricians use it to peer inside a woman's uterus and observe a growing baby. Surgeons use powerful beams of ultrasound to destroy cancer cells. Researchers fire ultrasound into materials to test their properties. But these high-frequency acoustic waves can do even more, say investigators.
