Laboratory chamber walls have been stealing vapors, causing researchers to underestimate the formation of secondary organic aerosol in the atmosphere. A study published April 7 in PNAS Online Early ...

What is Particle Size Distribution Analysis? To determine the size and range of particles in a specific material, particle size distribution (PSD) analysis is used. Several techniques are used to ...

The void fraction, an important powder packing property, directly impacts many of the powder's physical characteristics and applications. To demonstrate how the variation in powder particle size ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.
