The film "The Colloidal State" explores the concept of colloids, which are materials in a dispersion where small particles of one substance are distributed throughout another. It distinguishes ...

Colloids are simply fine particles of solids, liquids, or gases suspended in a fluid. And you can find colloidal systems almost everywhere in nature and in industrial processes, such as in butter, ...

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, ...

Vinothan N. Manoharan holds up a small vial of liquid. It looks something like milk—white and opaque and otherwise unremarkable. But the particles that make up this suspension could one day be used to ...

Colloidal particles undergo perpetual Brownian motion resulting from the stochastic and rapid collisions with solvent molecules. As a result, an ensemble of colloidal particles spreads diffusively to ...

Colloidal suspensions of microscopic particles show complex and interesting collective behaviors. In particular, the collective dynamics of colloids is fundamental and ubiquitous for materials ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Fractals are remarkable examples of self-similarity where a structure or dynamic pattern is repeated over multiple spatial or time scales. However, little is known about how fractal stimuli such as ...

Soil is composed of organic matter, minerals, gases, liquids, and organisms that together support life. It is a responsible for the plant growth; means of water storage, supply and purification; ...

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.
