Researchers at PSI and the University of Barcelona have managed to explain the strange behavior of microgels. Their measurements using neutron beams have pushed this measuring technique to its limits.

When calculating electrokinetic force, the convention has been to assume that there is no relative velocity of the fluid compared to the surface, which holds true for hydrophilic surfaces. However, ...

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 ...

For colloidal particles adsorbed at liquid/liquid interfaces, it is now found that the height of a particle above the interface equilibrates much more slowly than expected. Such a slow relaxation has ...

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, ...

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, ...

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. Scientists have devised a way of ...

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 are mixtures containing solids in liquid or liquid in liquid and all of these contain distinct solid (and/or liquid) particles which are dispersed to various degrees in a liquid medium. The ...

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; ...

Colloids are distinguished from other types of mixtures by several important distinctive properties, one of which is the electrokinetic force in colloidal suspensions, also known as the "zeta ...
