Researchers develop cryogenic coffee grinding technology

Skoltech Ph.D. Dima Smirnov and his colleagues from St. Petersburg, Alexander Saichenko, Vladimir Dvortsov, Mikhail Tkachenko, and Maxim Kukolev developed a cryogenic cooling technology and combined it with a cryogenic grinding ...

Researchers study black carbon aerosol in urban Beijing

Black carbon (BC) is the product of incomplete combustion of fossil fuels, biofuel and biomass. By strongly absorbing solar radiation, BC can heat the atmosphere, affect its stability, and further deteriorate air quality.

Raman holography for biology

Raman spectroscopy is widely used in analytical sciences to identify molecules via their structural fingerprint. In the biological context the Raman response provides a valuable label-free specific contrast that allows distinguishing ...

Single-atom alloy: Superb cocatalyst for photocatalysis

Photocatalysis, converting solar energy into chemical energy, has been recognized to be a very promising solution to current energy and environmental issues. The performance of the photocatalytic system depends largely on ...

New method determines planetary regolith thermal conductivity
