Using ultrasound, doctors can monitor the particles’ journey through the bloodstream, ensuring they reach their target. “Previously, researchers primarily investigated tiny gas bubbles as a ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

Particle sizes are determined by the mechanism through which the particles enter the atmosphere. For example, homogeneous nucleation, in which a new particle is formed directly from the gas phase ...

The properties of a substance are the properties of a huge number of particles together. In this episode, Dr Sunayana Bhargava and Tulela Pea explore the states of matter: solid, liquid and gas.

The focus is that matter, whether solid, liquid, or gas, is made up of particles; that dissolving and evaporation happen at the particle level; and that models can help explain these processes that we ...
