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 ...

Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a ...

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 ...

With low particulate loading common in stack emissions these days, particulate matter measurement can be difficult using traditional techniques. Microscopical measurement of particle-size ...

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 ...

Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics. Fundamental particles are objects that are so small, they have no deeper ...
