Colloids are heterogeneous physical systems in which one phase (dispersed phase) is finely distributed within another continuous phase, with characteristic particle or domain sizes typically in the range of ~1–1000 nm. They exhibit properties dominated by interfacial phenomena, Brownian motion, and long-range interactions rather than gravitational settling. Colloidal stability is governed by a balance of van der Waals, electrostatic, steric, and depletion forces, often described by DLVO and extended theories. These systems encompass sols, gels, emulsions, foams, and aerosols, and serve as model platforms for studying phase behavior, self-assembly, rheology, and non-equilibrium dynamics in soft condensed matter physics.
A research team led by Seil Kim of the Korea Institute of Materials Science (KIMS) Energy & Environmental Materials Research Division has developed an Ag–PTFE composite plating technology that produces silver coatings with ...

This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical ...
Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according to a new study from the ...

Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...
The CIC biomaGUNE Center for Cooperative Research in Biomaterials has developed pulmonary surfactant nanoparticles (the blend of lipids and proteins that line the alveoli and enables breathing), which are encapsulated in ...
