Scientists devised a new approach that balances attractions between particles and promises to become a useful tool to create designer materials that can repair damage. Scientists devised a new ...

Temperature can switch the thermodynamic phase of colloid–polymer mixtures by tipping the balance between competing attractive interactions induced by polymer depletion or adsorption. Figure 1: ...

"Lab-on-a-chip" devices – which can carry out several laboratory functions on a single, micro-sized chip – are the result of a quiet scientific revolution over the past few years. For example, they ...

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But ...

Lab-on-a-chip microfluidic devices can manipulate liquids at ever smaller scales. Atdr gs/Wikimedia Commons, CC BY-SA “Lab-on-a-chip” devices – which can carry out several laboratory functions on a ...

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed - for the first time experimentally - the Brazil nut effect in a mixture of charged ...

Five different phases of a colloid-polymer mixture can co-exist at the same time, in defiance of the 150-year-old Gibbs phase rule, which states that only three simultaneous phases are possible. The ...

150 years of research and development have transformed colloidal silica from a scientific oddity to a mainstay of industrial manufacturing of products ranging from floor wax to jet engines Every child ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...
