Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in ...

For more than a century, scientists have treated chemistry as the master key to building new materials, tuning bonds and charges to coax atoms into useful patterns. A new wave of research is quietly ...

Have you ever spilled coffee on a solid surface such as the floor, table or clothing? Most of us have had the experience, but if you have not, or if you are curious, spill just a drop and let it dry ...

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 ...

Colloidal silver is a suspension of tiny particles of silver in a liquid, or sometimes gel. The particles are so small that they can’t be filtered out of the solution; these nanoparticles range from ...

Engineers discover unusual properties in magnetized colloids that surprisingly adhere to the physics described by Kelvin's equation, which models the thermodynamics of molecular systems. Small spheres ...

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, ...

DNA is a fascinating macromolecule that guides protein production and enables cell replication. It has also found applications in nanoscience and materials design. Colloidal crystals are ordered ...

Colloidal gold consists of microscopic particles of gold suspended in liquid and is usually red or purple. It comes from shale or clay deposits. There has been much debate about the health benefits of ...
