Colloidal suspensions undergo Brownian diffusion that arrests at high density, remobilizing under flow. Slowly sheared non-Brownian particles (dry or in suspension) likewise show chaotic trajectories, ...

The study of nanoparticle interactions within colloidal suspensions has advanced considerably, laying the groundwork for both industrial applications and theoretical developments. At the heart of this ...

Lee R. White wanted to be a theoretical physicist. But while he was finishing his doctoral degree, an applied math professor talked him into examining the forces between particles in solution.

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...
