Unexpected drop of dynamical heterogeneities in colloidal suspensions approaching the jamming transition

, 2008
As the glass (in molecular fluids\cite{Donth}) or the jamming (in colloids and grains\cite{LiuNature1998}) transitions are approached, the dynamics slow down dramatically with no marked structural changes.

Active Anisotropic Colloids from Colloidal Monolayers [PDF]

, 2021
In this thesis we describe several colloidal model systems. We first study the lattice structures in monolayers of colloidal superballs prepared using the unidirectional rubbing method. In this method, the ordering of the colloidal superballs is achieved by mechanically rubbing them onto a polydimethylsiloxane- (PDMS) coated surface. We show using both

Effective forces between colloids at interfaces induced by capillary wave-like fluctuations

, 2006
We calculate the effective force mediated by thermally excited capillary waves between spherical or disklike colloids trapped at a fluid interface. This Casimir type interaction is shown to depend sensitively on the boundary conditions imposed at the ...

Colloidal Dynamics on Disordered Substrates

, 2001
Using Langevin simulations we examine driven colloids interacting with quenched disorder. For weak substrates the colloids form an ordered state and depin elastically. For increasing substrate strength we find a sharp crossover to inhomogeneous depinning

Control mechanism of short-term fertilization with cattle manure on the release characteristics of soil colloids in farmland: grain size and physicochemical properties

Environmental Sciences Europe
Background Understanding the release characteristics of soil colloids is a prerequisite for studying the co-transport of colloids and pollutants in subsurface environment.

Multivalent display of minimal Clostridium difficile glycan epitopes mimics antigenic properties of larger glycans

Nature Communications, 2016
Immunologically-active glycans are promising vaccine candidates but can be difficult to synthesize. Here, the authors show that pentavalent display of a minimal disaccharde epitope on a chemical scaffold can mimic a native C.

Phase behaviour of charged colloidal sphere dispersions with added polymer chains

, 2005
We study the stability of mixtures of highly screened repulsive charged spheres and non-adsorbing ideal polymer chains in a common solvent using free volume theory.

Diffusional Growth of Colloids

, 1998
We consider incorporation of particle detachment in Smoluchowski model of colloidal growth. Two approaches are considered, utilizing phenomenological rate equation and exact large-time results.

Novel Colloidal Crystalline States on Two Dimensional Periodic Substrates

, 2002
We show using numerical simulations that a rich variety of novel colloidal crystalline states are realized on square and triangular two dimensional periodic substrates which can be experimentally created using crossed laser arrays.

Collective behavior of colloids due to critical Casimir interactions

, 2017
If colloidal solute particles are suspended in a solvent close to its critical point, they act as cavities in a fluctuating medium and thereby restrict and modify the fluctuation spectrum in a way which depends on their relative configuration.
