Revolutionizing electronics using Kirigami

Fri, 12/08/2017 - 12:23pm
A research team has developed an ultrastretchable bioprobe using a 'Kirigami' designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.

Three kinds of information from a single X-ray measurement

Fri, 12/08/2017 - 11:30am
The way in which electronic devices operate relies on the interaction between various materials. For this reason, researchers need to know exactly how specific chemical elements inside a computer chip or a transistor diode behave, and what happens when these elements bond. Physicists have now developed an innovative method that enables them to obtain several different types of information simultaneously from the interior of a nanoscale building block, and this while it is in the active state.

Physicists excited by discovery of new form of matter, excitonium

Fri, 12/08/2017 - 11:30am
Excitonium has a team of researchers ... well... excited! They have demonstrated the existence of an enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago.

Blackbody radiation from a warm object attracts polarizable objects

Fri, 12/08/2017 - 11:30am
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.

Transformation to wind and solar achievable with low indirect GHG emissions

Fri, 12/08/2017 - 8:35am
Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.

Device makes power conversion more efficient

Thu, 12/07/2017 - 12:45pm
Researchers have presented a new design that, in tests, enabled gallium nitride power devices to handle voltages of 1,200 volts. That's already enough capacity for use in electric vehicles, but the researchers believe that further work can boost its capacity to the 3,300-to-5,000-volt range, to bring the efficiencies of gallium nitride to the power electronics in the electrical grid itself.
