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, ...

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 ...

Colloidal suspensions heterogenous mixtures of particles with diameters of about 2-500 nanometers, which are permanently suspended in a second phase, usually a liquid. Owing to the small particle size ...

Nanotechnology is generally seen as a relatively new invention. It is generally accepted to have been officially born as a discipline with Richard Feynman's 1959 lecture, "There's plenty of room at ...

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 ...

Colloidal particles have the right size to form ordered structures with periodicities comparable to the wavelength of visible light. The tantalizing colours of precious opals and the colour of some ...

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; ...

Particles are of a colloidal size if their size falls in the range of 1 to 1000nm. A colloid is system whereby colloidal particles are suspended in a continuous medium. They are stable and do not ...

Being abundant in nature, colloids find increasingly important applications in science and technology, ranging from direct probing of kinetics in crystals and glasses to fabrication of ...

Urine is a highly saturated solution of extremely complicated composition. Its basic organic constituents are urea, uric acid and its salts, formed by the oxidation of purines. In that fluid, ...
