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, ...

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.

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, ...

Swelling colloids – mixtures, such as milk and paint, in which particles are suspended in a substance and which can grow up to 100 times larger under certain temperatures – could be used to fix flow ...

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 ...

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, ...

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 ...

Colloids are particles that have a diameter of between approximately 1 and 1,000 nanometres and that are evenly dispersed in fluids. Colloids are also known as colloidal dispersions because the ...

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 ...

Self-organization of soft-matter components can create complex and beautiful structures. But the intricate structures created by adding a second stage of organization could reveal more than just a ...
