We consider star polymer mixtures that are asymmetric both in functionality and in size, focusing on the addition of smaller stars to a dense solution of larger ones, which, in the absence of the ...

The soft, solid-like properties of colloidal gels are essential in fields such as food and medical applications, but how these properties manifest themselves is a long-standing mystery. Until now, it ...

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 ...

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 ...

(Phys.org)—Colloidal systems are important in nanoscience and materials. A colloidal system involves the dispersion of particles within a solvent. A stable colloid has evenly dispersed solute ...

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 ...

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 ...

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 ...
