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 ...

(a) Turbostratic (soot) particles (diameter 67 nm). (b) Onion-like particles (diameter 17 nm). (c) Amorphous particles (diameter 26 nm). (d) Trace amorphous particles (diameter 17 nm). The four ...

Many products are dispersions or suspensions of particles in a liquid medium. Examples range from ceramics, adhesives, inks and paints through to drinks, foods, medicines and personal care products.

The health implications of particulate matter (PM) depend largely on its size and composition. Fine particles like PM2.5 (aerodynamic diameter < 2.5 μm) pose severe health risks, penetrating deep into ...
