Cheyenne was ranked the eighth-cleanest city in the nation for year-round average particle pollution, while Casper was ranked first in the country in the newest “State of the Air” report from the ...

The LA area is once again the worst for ozone in the U.S., a pollutant impacting millions more people nationwide, the ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

Particle sizes are determined by the mechanism ... Collectively, all particles smaller than 2.5 micrometers (PM 2.5) are known as fine aerosols. Particles with diameters between 2.5 and 10 ...

The particles analyzed are extremely small, measuring only 12 micrometers (12 millionths of a metre) in diameter. Creating a proper measurement technique for the particle's rolling friction was ...

“For AEgIS to work, we need a detector with incredibly high spatial resolution, and mobile camera sensors have pixels smaller than 1 micrometer,” says Francesco Guatieri from the ... self-calibration ...

The Department’s strong fields of research include particle physics, astrophysics and space physics ... from the the atomic and nanoscale to macroscopic large objects with micrometer resolution. We ...
