Polarized imaging of dynamic light scattering to measure nanoparticle size, morphology, and distributions

A team of researchers proposed a fast and convenient method called polarized imaging dynamic light scattering (PIDLS) that quantitively evaluates nanoparticle size, morphology and distribution at the same time. A dimensionless ...

Active Brownian particles have four distinct states of motion, researchers find

Active Brownian motion describes particles that can propel themselves forward while still being subjected to random Brownian motions as they are jostled around by their neighboring particles. Through a new analysis published ...

Breaking down the Nernst–Einstein relation, carbon nanotube style

When it comes to studying particles in motion, experimentalists have followed a 100-year-old theory that claims the microscopic motion of a particle is determined by random collisions with molecules of the surrounding medium, ...

A surprising way to trap a microparticle

When physicists recently steered a tiny microparticle toward a cylindrical obstacle, they expected one of two outcomes to occur. The particle would either collide into the obstacle or sail around it. The particle, however, ...
