It has long been known that the optical resonances of ultrahigh-Q whispering gallery mode resonators can split under the influence of particle scattering. Now scientists have exploited this splitting ...

Particle size analysis is used to characterize the size distribution of particles in a sample. This analysis can also be used to measure the particle size of solid materials, suspensions, emulsions, ...

Particle size decreases predictably as grinding time increases, meaning P80 serves as a practical operational parameter when ...

Research was conducted to determine the optimum laser diffraction-based particle sizing dispersion method for Domperidone API. This study employed the Bettersizer 2600 - an automatic laser diffraction ...

Particles are contained in several types of materials. They are found in granules and powders like pharmaceutical ingredients, cement, and pigments. Particles are present in slurries, emulsions, and ...

A long-awaited experimental result has found the proton to be about 5% smaller than the previously accepted value. The finding has helped to prompt a redefinition of the particle’s official size and ...

An analysis of counting-efficiency effects in non-volumetric particle counters explains discrepancies across channels.
