As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

Colloids have increasingly been used to characterize or mimic many aspects of atomic and
molecular systems. With confocal microscopy these colloidal particles can be tracked …

Solutions of different polymers in the same solvent are incompatible as a rule and show
phase separation when they are mixed. H incompatibility is also to be observed in systems …

We examine the structure of the distribution of single particle displacements (van Hove
function) in a broad class of materials close to glass and jamming transitions. In a wide time …

Optical measurement techniques such as particle image velocimetry (PIV) and laser Doppler
velocimetry (LDV) are now routinely used in experimental fluid mechanics to investigate …

Hard-sphere colloids are popular as models for testing fundamental theories in condensed
matter and statistical physics, from crystal nucleation to the glass transition. A single …

Abstract Coherent anti‐Stokes Raman scattering (CARS) microscopy is presented as a new
nonlinear optical technique. The combination of vibrational spectroscopy and microscopy …

Systems of spherical colloidal particles mimic the thermodynamics of atomic crystals. Control
of interparticle interactions in colloids, which has recently begun to be extensively exploited …

Experimental techniques based on optical measurement principles have experienced
significant growth in recent decades. They are able to provide detailed information with high …

Water-lutidine mixtures permit the interparticle potentials of colloidal particles suspended
therein to be tuned, in situ, from repulsive to attractive. We employ these systems to directly …
