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 ...

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 ...

Temperature can switch the thermodynamic phase of colloid–polymer mixtures by tipping the balance between competing attractive interactions induced by polymer depletion or adsorption. Figure 1: ...
