Quantum mechanics prohibits any quantum system from achieving a temperature that is equal to absolute zero. However, using Laser cooling, which is a highly efficient spectroscopic technique, atomic samples could be cooled to near absolute zero thus bringing them to their lowest achievable quantum energy state. Scientists have been advancing this technique for decades now and an important question that arose recently is whether carbon molecules, which are an integral component of life on earth, could be laser-cooled.

Thermoelectrics: From heat to electricity
Posted by Shubham Ghosh Roy in categories: energy, physics
A lot of heat gets lost during the conversion of energy. Estimates even put it at more than 70%. However, in thermoelectric materials, such as those being studied at the Institute of Solid State Physics at TU Wien, heat can be converted directly into electrical energy. This effect (the Seebeck effect) can be used in numerous applications in industry but also in everyday life.
Recently, Ernst Bauer’s research team made an exciting discovery in a thermoelectric material consisting of iron, vanadium and aluminum (Fe2VAl). The researchers recently published their results in Nature Communications.

“The construction of the storage went well, especially considering that the solution is completely new,” said Polar Night co-founder and chief technology officer Markku Ylönen in a statement.
“We managed to get everything in order despite some challenges and a short delay.”

A gentler, more precise laser cutting technique
Posted by Dan Breeden in categories: energy, materials
Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University have developed a gentler, more precise technique using low-power visible light.
