Suppressing the Auger recombination process in quantum dots

A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...

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.

Examining cell shapes without a microscope

Scientists from Nara Institute of Science and Technology (NAIST) measured changes in electrical conductivity caused by cells passing through a tiny channel to determine if they were spherical or elongated. They found that ...
