Cyberattacks may become impossible with the creation of the first practical quantum random number generator.
An EU initiative shows promising developments towards improved wireless connectivity between networks and users.
Scientists from the National Research Nuclear University MEPhI (Russia) have studied the properties of fullerene nanotubes, also known as "carbon peas," during stretching. The article on the project, which will help develop ...
Recent studies have revealed that semiconductor nanowires offer unique advantages for a wide range of applications. An EU-funded project is breaking new ground in the move towards sustainable and efficient energy harvesting ...
A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change ...
Solar cells can't stand the heat. Photovoltaics lose some energy as heat in converting sunlight to electricity. The reverse holds true for lights made with light-emitting diodes (LED), which convert electricity into light. ...
Most sunlight striking the Earth is absorbed by its surfaces, oceans and atmosphere. As a result of this warming, infrared radiation is emitted constantly all around us-estimated to be millions of Gigawatts per second. A ...
The research team that announced the first optical rectenna in 2015 is now reporting a two-fold efficiency improvement in the devices—and a switch to air-stable diode materials. The improvements could allow the rectennas ...
National University of Singapore scientists have developed energy efficient ultra-thin light-emitting diodes (LEDs) for next generation communication technologies.
With concerns over moving to a clean energy platform worldwide with electric vehicles and renewables, wasted energy is a factor as important as the amount of green energy produced. Thus, solid-state lighting based upon light-emitting ...
