Two-phase equilibrium: A binary colloidal mixture can exist in up to six phases at the same time. (Courtesy: R Tuiner) A binary colloidal mixture can exist in up to six phases at the same time, ...

In Fig. 1e we show the time dependence of B measured when a bipolar electric pulse E(t) (where t is time; black line) is applied to the same samples shown in Fig. 1a, showing normal (green line) and ...

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 ...

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But ...
