Effective interactions and phase behaviour for a model clay suspension in an electrolyte
, 2002 Since the early observation of nematic phases of disc-like clay colloids by Langmuir in 1938, the phase behaviour of such systems has resisted theoretical understanding. The main reason is that there is no satisfactory generalization for charged discs of

Active colloids at fluid interfaces
, 2016 If an active Janus particle is trapped at the interface between a liquid and a fluid, its self-propelled motion along the interface is affected by a net torque on the particle due to the viscosity contrast between the two adjacent fluid phases.

Automated assembly of oligosaccharides containing multiple cis-glycosidic linkages
Nature Communications, 2016 Automated glycan assembly has proven a powerful method to rapidly synthesize large oligosaccharides, though stereoselective cis-glycosylation remains a challenge.

Frontiers in Physics, 2015 Molecular crowding is ubiquitous within cells and affects many biological processes including protein-protein binding, enzyme activities and gene regulation. Here we revisit some generic effects of crowding using a combination of lattice simulations and

Configurational and energy landscape in one-dimensional Coulomb systems
, 2016 We study a one dimensional Coulomb system, where two charged colloids are neutralized by a collection of point counterions, with global neutrality. Temperature being given, two situations are addressed: the colloids are either kept at fixed positions ...

Advanced Materials, 2008 Several configurations of colloidal wires are obtained by infiltration of charge-stabilized polystyrene spheres into cylindrical pores of a silicon membrane (see figure). As channel dimensions are comparable to those of particles, wirelike arrangements are governed by the ratio between the pore diameter and the particle diameter.

Infrared and photocatalytic studies of model bacterial species for water treatment [PDF]
, 2006 The use of a CO2 infrared (IR) laser and photocatalysis for water treatment microorganism disinfection purposes was investigated. During CO2 infrared (IR) laser treatment E. cloacae inactivation was comparable to inactivation via ultraviolet (UV)

Royal Society Open ScienceColloid-based computing devices offer remarkable fault tolerance and adaptability to varying environmental conditions due to their amorphous structure. An intriguing observation is that a colloidal suspension of ZnO nanoparticles in dimethylsulfoxide (DMSO) exhibits reconfiguration when exposed to electrical stimulation and produces spikes of ...
