Non-toxic filamentous virus helps quickly dissipate heat generated by electronic devices

Tue, 2018-04-03 18:20
Scientists have discovered that the film constructed by assembling a nontoxic filamentous virus functions as a heat dissipation material, and that can be simply prepared by drying the virus aqueous solution at room temperature. This discovery is expected to elucidate the mechanism of new heat transport in electronics.

Engineers turn plastic insulator into heat conductor

Sat, 2018-03-31 00:23
Is your laptop or phone overheating? Newly engineered plastic could lead to self-cooling casings for common electronics.

A novel test bed for non-equilibrium many-body physics

Fri, 2018-03-30 20:28
The behavior of electrons in a material is typically difficult to predict. Novel insight comes now from experiments and simulations performed by physicists who have studied electronic transport properties in a one-dimensional quantum wire containing a mesoscopic lattice.

Scientists print all-liquid 3-D structures

Wed, 2018-03-28 22:33
Scientists have developed a way to print 3-D structures composed entirely of liquids. Using a modified 3-D printer, they injected threads of water into silicone oil -- sculpting tubes made of one liquid within another liquid.

Knitting electronics with yarn batteries

Wed, 2018-03-28 18:04
When someone thinks about knitting, they usually don't conjure up an image of sweaters and scarves made of yarn that can power watches and lights. But that's just what one group is reporting. They have developed a rechargeable yarn battery that is waterproof and flexible. It also can be cut into pieces and still work.

The future of photonics using quantum dots

Tue, 2018-03-27 23:47
Fiber-optic cables package everything from financial data to cat videos into light, but when the signal arrives at your local data center, it runs into a silicon bottleneck. Instead of light, computers run on electrons moving through silicon-based chips, which are less efficient than photonics. To break through, scientists have been developing lasers that work on silicon. Researchers now write that the future of silicon-based lasers may be in quantum dots.

Paper-folding art inspires better bandages

Tue, 2018-03-27 20:35
Cutting kirigami-style slits in stretchy films could make for stickier bandages, heat pads, wearable electronics, according to a new study.

Tattoo electrodes from an ink-jet printer

Tue, 2018-03-27 19:10
Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer.

Blowin' in the wind -- A source of energy?

Tue, 2018-03-27 00:53
It may in the future be possible to harvest energy with the aid of leaves fluttering in the wind. Researchers have developed a method and a material that generate an electrical impulse when the light fluctuates from sunshine to shade and vice versa.

Understanding charge transfers in molecular electronics

Mon, 2018-03-26 23:32
Scientists have found a way to understand and manipulate the transition of charges in molecular junctions.

Smaller and faster: The terahertz computer chip is now within reach

Sun, 2018-03-25 21:28
Following three years of extensive research, physicists have created technology that will enable our computers —- and all optic communication devices —- to run 100 times faster through terahertz microchips.

Flexible ultrasound patch could make it easier to inspect damage in odd-shaped structures

Fri, 2018-03-23 23:43
Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks -- objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface.

Generation of a stable biradical

Thu, 2018-03-22 20:57
Researchers in Germany have succeeded in twisting molecules so much that their double bonds have been completely destroyed. The result: unusually stable biradicals.

Scientists control molecular alignment on a graphene surface

Thu, 2018-03-22 20:03
Scientists have developed a simple way to align molecules in one direction on a flat graphene surface. Efficiently controlling molecular alignment is expected to lead to significant progress in surface chemistry and molecular engineering, as well as materials science.

Electric textile lights a lamp when stretched

Thu, 2018-03-22 20:03
Working up a sweat from carrying a heavy load? That is when the textile works at its best. Researchers have developed a fabric that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes the more electricity it generates.

Next-gen X-ray microscopy platform now operational

Wed, 2018-03-21 22:38
COSMIC, a next-generation X-ray beamline now operating at Berkeley Lab, brings together a unique set of capabilities to measure the properties of materials at the nanoscale. It allows scientists to probe working batteries and other active chemical reactions, and to reveal new details about magnetism and correlated electronic materials.

Make way for the mini flying machines

Wed, 2018-03-21 18:37
Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines.

Improving fabrication process of nano-structures for electronic devices

Wed, 2018-03-21 02:07
Researchers have found a more efficient fabricating process to produce semiconductors used in today's electronic devices. They also confirmed that materials other than silicon can be used successfully in the development process that could increase performance of electronic devices.

'Candy cane' polymer weave could power future functional fabrics and devices

Tue, 2018-03-20 18:14
If scientists are going to deliver on the promise of implantable artificial organs or clothing that dries itself, they'll first need to solve the problem of inflexible batteries that run out of juice too quickly. Today, researchers report that they've developed a new material by weaving two polymers together in a way that increases charge storage capacity.

Existence of new form of electronic matter

Thu, 2018-03-15 00:20
Researchers have produced a 'human scale' demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.
