Video microscopy of colloidal suspensions and colloidal crystals [PDF]
Current Opinion in Colloid & Interface Science, 2002 Colloidal suspensions are simple model systems for the study of phase transitions. Video microscopy is capable of directly imaging the structure and dynamics of colloidal suspensions in different phases. Recent results related to crystallization, glasses, and 2D systems complement and extend previous theoretical and experimental studies.

Shape-preserving erosion controlled by the graded microarchitecture of shark tooth enameloid
Nature Communications, 2020 Shark teeth have short lifespans yet can be subject to significant mechanical damage. Here, the authors report on a site-specific damage mechanism in shark teeth enameloid, which maintains tooth functional shape, providing experimental evidence that ...

The Importance of Boundary Conditions for Fluctuation Induced Forces between Colloids at Interfaces
, 2006 We calculate the effective fluctuation induced force between spherical or disk-like colloids trapped at a flat, fluid interface mediated by thermally excited capillary waves.

Dichloromethylation of enones by carbon nitride photocatalysis
Nature Communications, 2020 Long-lived carbon nitride radicals have been used in several photocatalytic reactions. Herein, long-lived potassium poly(heptazine imide) radicals enable synthesis of γ,γ-dichloroketones from enones by addition of CHCl2 moiety, generated from chloroform,

Sedimentation of active colloidal suspensions
, 2010 In this paper, we investigate experimentally the non-equilibrium steady state of an active colloidal suspension under gravity field. The active particles are made of chemically powered colloids, showing self propulsion in the presence of an added fuel ...
