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 ...

A colloidal solution is a uniform dispersion of two completely different types of components—particles or droplets of one phase, called the solute, in a second, typically liquid, phase, called the ...

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 ...

Physicists in the Netherlands have created artificial crystals made of colloidal particles that could be used to explore the behaviour of ordinary ionic crystals. The team discovered a number of new ...

A research team simulated phase separation in colloidal suspensions. By treating colloid particles as undeformable highly viscous liquid droplets suspended in a solvent, they predicted the kinetics of ...
