Particle size has long been a key method for characterization. Most particle size measurement techniques are indirect and assume that all measured particles are round when providing size results.

Hollow Glass Microspheres are inorganic, nonmetallic spherical materials created by specific processes, commonly with diameters in the range of 10 to 250 μm and wall thicknesses of 1 to 2 μm (Figure 1 ...

Researchers from Trinity College Dublin’s School of Engineering have built a powerful new machine that lets us watch precisely what happens when tiny particles — far smaller than a grain of sand — hit ...
