Researchers fabricate large-area sky-blue PeLEDs

The research group led by Prof. Xiao Zhengguo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences prepared large-area and efficient sky-blue perovskite light-emitting diodes (PeLEDs) ...

Characterizing super-semi sandwiches for quantum computing

Semiconductors are the foundation of modern technology while superconductors with their zero electrical resistance could become the basis for future technologies, including quantum computers. So-called "hybrid structures"—carefully ...

Mini electricity generator made from quantum dots

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology ...

New view of deep rock fractures for geothermal energy

Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes happening in the rock over ...

Thermoelectric crystal conductivity reaches a new high

Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its "Peltier conductivity" (P). Now, researchers from Japan demonstrate ...

Toward self-restoring electronic devices with long DNA molecules

The potential of DNA structural properties in single-molecule electronics has finally been harnessed by researchers from Tokyo Institute of Technology (Tokyo Tech) in a single-molecule junction device that shows spontaneous ...

Exploring a unique material with tunable properties

If you're old enough, you may still have a box of cassette or VHS tapes lying around. These storage devices were popular in the 1970s and 80s, but have since fallen into disuse, replaced by CDs and other digital media.

Woven nanotube fibers turn heat into power

Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other sources into energy.
