Scientists borrow from electronics to build circuits in living cells

Thu, 2017-05-25 18:21
Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the largest ever published to date in eurkaryotic cells and a key step in harnessing the potential of cells as living computers that can respond to disease, efficiently produce biofuels or develop plant-based chemicals.

One-dimensional crystals for low-temperature thermoelectric cooling

Wed, 2017-05-24 19:45
Researchers studied the thermal and electrical properties of one-dimensional crystals composed of tantalum, silicon and tellurium for thermoelectric cooling at temperatures below 250 K (-23°C). The thermoelectric characteristics of these crystals were varied at temperatures ranging from the cryogenic level of 50 K up to room temperature by doping with molybdenum and antimony. The crystals' thermoelectric power factors greatly exceeded those of conventional materials around room temperature, indicating their suitability for low-temperature applications.

Off-the-shelf, power-generating clothes are almost here

Tue, 2017-05-23 18:07
A lightweight, comfortable jacket that can generate the power to light up a jogger at night may sound futuristic, but a materials scientist could make one today. In a new paper, she and colleagues outline a way to apply breathable, pliable, metal-free electrodes to fabric and off-the-shelf clothing so it feels good to the touch and also transports enough electricity to power small electronics.

Researchers create first significant examples of optical crystallography for nanomaterials

Fri, 2017-05-19 00:08
Researchers have developed a novel way to determine crystal type based on optics -- by identifying the unique ways in which these crystals absorb light.

World's thinnest hologram paves path to new 3-D world

Thu, 2017-05-18 18:00
Researchers pave way towards integration of 3-D holography into electronics like smart phones, computers and TVs, with development of nano-hologram 1,000 times thinner than a human hair.

Using graphene to create quantum bits

Thu, 2017-05-18 18:00
In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

Better cathode materials for lithium-sulphur-batteries

Wed, 2017-05-17 19:42
Scientists have for the first time fabricated a nanomaterial made from nanoparticles of a titanium oxide compound (Ti4O7) that is characterized by an extremely large surface area, and tested it as a cathode material in lithium-sulphur batteries. The highly porous nanomaterial possesses high storage capacity that remains nearly constant over many charging cycles.

Tue, 2017-05-16 02:47
Electronic devices that can not only be implanted in the human body but also completely dissolve on their own – known as “bioresorbable” electronics – are envisioned by many as one of medical technology’s next frontiers. A new study suggests that a laser printing technique using nanoparticles could help unlock a more cost-effective approach to building sturdier and safer components.

Can the motion of checking your smartwatch charge it?

Wed, 2017-05-10 22:49
Triboelectric nanogenerators (TENGs) are small devices that convert movement into electricity, and might just be what bring us into an era of energy-harvesting clothes and implants. But could TENGs, even theoretically, give us wearable electronics powered solely by the wearer's day-to-day body motion? The short answer is yes. New research demonstrates the ability of mechanical energy produced by typical body motions to power a watch or smartphone.
