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 ...

All-inorganic nanocrystals boost infrared emission

New chemistry has been developed to integrate lead chalcogenide nanocrystals into continuous inorganic matrices of chalcogenide glasses. Inorganic capping, rather than conventional organic capping ligands, allows simple and ...

Scientists map changes in soot particles emitted from wildfires

Not many people would voluntarily fly through plumes of smoke emitted from wildfires. But atmospheric scientists from the U.S. Department of Energy's Brookhaven National Laboratory do, over and over, tracing flight paths ...

Particle size matters for porous building blocks

Porous particles of calcium and silicate show potential as building blocks for a host of applications like self-healing materials, bone-tissue engineering, drug delivery, insulation, ceramics and construction materials, according ...

Silver nanoparticles on graphene oxide support

Silver (Ag) has a high catalytic activity towards many organic and inorganic transformations such as NOx reduction and catalytic oxidation of CO to CO2. In practical applications, catalysts like Ag are affixed to a substrate, ...

Physicists design a model of Martian winter

A team of researchers from MIPT and their German and Japanese colleagues have designed a numerical model of the annual water cycle in the Martian atmosphere. Previously, the scientists focused their research on relatively ...

Music-making and the flow of aerosols

The latest research from the labs of Penn scientists Paulo Arratia and Douglas Jerolmack was an answer to "a call for help," says Arratia.
