Pollutant particles with a smaller diameter, density, and flow rate can enter the deep lung, but large particles with a low density may also enter the deep airways, according to a study. Researchers ...

Physicists love to smash particles together and study the resulting chaos. Therein lies the discovery of new particles and strange physics, generated for tiny fractions of a second and recreating ...

Cohesion is often seen as a key factor to bulk powder flowability and is frequently blamed for problems in powder processing. Particles attract to one another in cohesive powder to create agglomerates ...
