Colloid particles that form bonds to each other at specific orientations might self-assemble into all sorts of useful materials. The key — and the lock — to such binding has been discovered. Colloidal ...

Colloids—mixtures of particles made from one substance, dispersed in another substance—crop up in numerous areas of everyday life, including cosmetics, food and dyes, and form important systems within ...

(Phys.org)—Colloidal systems are important in nanoscience and materials. A colloidal system involves the dispersion of particles within a solvent. A stable colloid has evenly dispersed solute ...

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 ...

Scientists devised a new approach that balances attractions between particles and promises to become a useful tool to create designer materials that can repair damage. Scientists devised a new ...

Life-like laser: Titanium dioxide microparticles clustering around a Janus particle. The dashed line delineates the lasing area, and the pink/yellow lines show the 275 s-long tracks of several ...

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 ...
