Wiggling atoms switch the electric polarization of crystals

Fri, 2018-04-13 01:14
A time-resolved x-ray experiment now elucidates that tiny atomic vibrations shift negative charges over a 1000 times larger distance between atoms and switch the macroscopic polarization on a time scale of a millionth of a millionth of a second.

Recycling experts hit milestone in quest for zero-waste phone

Thu, 2018-04-12 20:39
UBC researchers have perfected a process to efficiently separate fiberglass and resin -- two of the most commonly discarded parts of a cellphone -- bringing them closer to their goal of a zero-waste cellphone.

Thin, flexible polymers record 'conversations' deeper in the brain with less injury-risk

Thu, 2018-04-12 01:43
Researchers have developed thin, flexible polymer-based materials for use in microelectrode arrays that record activity more deeply in the brain and with more specific placement.

Smallest volume, most efficient wireless nerve stimulator

Wed, 2018-04-11 01:40
Engineers have taken their neural dust invention a step forward by building the smallest volume, most efficient wireless nerve stimulator to date.

Mini toolkit for measurements: New chip hints at quantum sensors of the future

Tue, 2018-04-10 22:58
Researchers have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such as length with quantum precision. The design could be mass-produced with existing technology.

New sodium-ion electrolyte may find use in solid-state batteries

Tue, 2018-04-10 22:58
A newly discovered structure of a sodium-based material allows the materials to be used as an electrolyte in solid-state batteries, according to researchers. The team is fine-tuning the material using an iterative design approach that they hope will shave years off the time from research to everyday use.

Diamond-based circuits can take the heat for advanced applications

Tue, 2018-04-10 20:39
When power generators transfer electricity, they lose almost 10 percent of the generated power. To address this, scientists are researching new diamond semiconductor circuits to make power conversion systems more efficient. Researchers have now successfully fabricated a key circuit in power conversion systems using hydrogenated diamond. These circuits can be used in diamond-based electronic devices that are smaller, lighter and more efficient than silicon-based devices.

Ultra-powerful batteries made safer, more efficient

Mon, 2018-04-09 20:55
Researchers are laying the foundation for more widespread use of lithium metal batteries. They have developed a method to mitigate the formation of dendrites -- crystal-like masses -- that damage the batteries' performance.

Creating a 2-D platinum magnet

Sat, 2018-04-07 01:24
Physicists have induced magnetism in platinum with an electric field created by a paramagnetic ionic liquid. As only the surface of the platinum is affected, this creates a switchable 2-D ferromagnet.

Why noise can enhance sensitivity to weak signals

Thu, 2018-04-05 19:03
Researchers have discovered a new mechanism to explain stochastic resonance, in which sensitivity to weak signals is enhanced by noise. The finding is expected to help electronic devices become smaller and more energy efficient.

Breakthrough made in atomically thin magnets

Wed, 2018-04-04 22:28
Researchers have become the first to control atomically thin magnets with an electric field, a breakthrough that provides a blueprint for producing exceptionally powerful and efficient data storage in computer chips, among other applications.

Pulling valuable metals from e-waste makes financial sense

Wed, 2018-04-04 19:09
Electronic waste -- including discarded televisions, computers and mobile phones -- is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it's been unclear whether it's reasonable from an economic viewpoint. Now researchers report that recovering gold, copper and other metals from e-waste is cheaper than obtaining these metals from mines.

High-speed and on-silicon-chip graphene blackbody emitters

Tue, 2018-04-03 20:41
High-speed light emitters integrated on silicon chips can enable novel architectures for silicon-based optoelectronics. However, compound-semiconductor-based light emitters face major challenges for their integration with a silicon-based platform because of their difficulty of direct fabrication on a silicon substrate. Here, high-speed, highly-integrated graphene-based on-silicon-chip blackbody emitters in the near-infrared (NIR) region including telecommunication wavelength were developed.

Ancient paper art, kirigami, poised to improve smart clothing

Tue, 2018-04-03 20:40
Scientists describe how kirigami has inspired its efforts to build malleable electronic circuits. Their innovation -- creating tiny sheets of strong yet bendable electronic materials made of select polymers and nanowires -- could lead to improvements in smart clothing, electronic skin and other applications that require pliable circuitry.

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.
