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 ...

Temperature can switch the thermodynamic phase of colloid–polymer mixtures by tipping the balance between competing attractive interactions induced by polymer depletion or adsorption. Such a ...
