EXPERIMENTAL AND MODELING STUDIES OF COLLOIDAL SUSPENSION STABILITY OF HIGH-DENSITY PARTICLES IN AQUEOUS SOLUTIONS
Agglomeration and sedimentation of suspended colloidal particles occur in many natural phenomena, in consumer products, and in engineering applications. Stabilized colloidal pigment dispersions were used in ancient Egypt and in ancient France thousands of years ago. Present day applications include …

Induced-charge electrokinetics at large voltages
… experimental puzzles include strange behavior of colloidal particles, high-frequency flow reversal in microfluidic ACEO pumps, and concentration dependence of electrokinetic slip. Theoretical developments would help not only in exploiting poorly understood effects favorably, but also in building …

Gel Development Using Cellulose Nanocrystals
Cellulose Nano Crystal (CNC) are naturally derived nanoparticles with a slender shape that own a remarkably high aspect ratio. Due to its mechanical properties with Young modulus in the range of 120-160 GPa and proven biocompatibility, CNC is an attractive nanoparticle for many applications. In the …
