Measurement of long-range steric repulsions between microspheres due to an adsorbed polymer [PDF]
, 2001 We have measured the interparticle potential between pairs of micron-sized silica spheres induced by adsorbed polyethylene oxide polymer using a line-scanned optical tweezer.

Water evaporation in silica colloidal deposits [PDF]
Journal of Colloid and Interface Science, 2013 The results of an experimental study on the evaporation and boiling of water confined in the pores of deposits made of mono-dispersed silica colloidal micro-spheres are reported. The deposits are studied using scanning electron microscopy, adsorption of nitrogen, and adsorption of water through attenuated total reflection-infrared spectroscopy.

From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]
, 2005 Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.

Colloidal chemistry with patchy silica nanoparticles [PDF]
Beilstein Journal of Nanotechnology, 2018 We report a new route to synthesize clusters, or so-called colloidal molecules (CMs), which mimic the symmetry of molecular structures made of one central atom. We couple site-specifically functionalized patchy nanoparticles, i.e., valence-endowed colloidal atoms (CAs), with complementary nanospheres through amide bonds.

Anisotropic deformation of colloidal particles under 4 MeV Cu ions irradiation
Materials Research Express, 2022 Anisotropic deformation of colloidal particles was investigated under ion irradiation with 4 MeV Cu ions. In this study, 0.5 μ m-diameter colloidal silica particles, 0.5 μ m-diameter Au-silica core–shell particles, and 15 nm-diameter Au colloids ...

Elimination of cracks in self-assembled photonic band gap crystals
, 2003 Thin colloidal crystals (or synthetic opals) composed of Stober silica spheres typically develop cracks when they are utilized to obtain photonic band gap crystals (or inverted opals). We find that by sintering the silica spheres prior to assembly of the

Journal of Colloid and Interface Science, 1969 Abstract The stabilities of the silica hydrosols Ludox HS and Ludox AM have been studied as a function of pH in the presence of various concentrations of several hydrolyzable electrolytes. “Log electrolyte concentration-pH” domains are given for the HS sol in Al(NO3)3 and Al2(SO4)3 solutions and for the AM sol in Al(NO3)3 and La(NO3)3 solutions.

Obstructed Diffusion in Silica Colloidal Crystals [PDF]
The Journal of Physical Chemistry A, 2013 The hindered diffusion in silica colloidal crystals was studied experimentally, both by fluorescence recovery after photobleaching and by measurement of ionic conductivity. Particle size was varied to include 120, 220, 470, and 1300 nm, and the porosities were determined by flow measurements.
