Sahara Desert dust found in remote European snow resorts

Saharan dust has made headlines in recent years for traveling across the globe, turning our skies picturesque hues of orange while coating our cities in thin layers of wind-blown dust. This has implications for our infrastructure ...

Titanium dioxide nanoreactor

Tiny particles of titanium dioxide are found as key ingredients in wall paints, sunscreens, and toothpaste; they act as reflectors of light or as abrasives. However with decreasing particle size and a corresponding change ...

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 ...

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 ...

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 ...

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 ...
