Phoretic Interactions Generically Induce Dynamic Clusters and Wave Patterns in Active Colloids. [PDF]

Physical Review Letters, 2017
We introduce a representative minimal model for phoretically interacting active colloids. Combining kinetic theory, linear stability analyses, and a general relation between self-propulsion and phoretic interactions in autodiffusiophoretic and ...

Nucleation and growth of sodium colloids in NaCl under irradiation: theory and experiment [PDF]

, 2005
A mechanism of radiation-induced emission of Schottky defects from extended defects proposed originally for metals has recently been applied to ionic crystals, where it is based on interactions of excitons with extended defects such as dislocations and ...

Sedimentation of binary mixtures of like- and oppositely charged colloids: the primitive model or effective pair potentials?

, 2005
We study sedimentation equilibrium of low-salt suspensions of binary mixtures of charged colloids, both by Monte Carlo simulations of an effective colloids-only system and by Poisson-Boltzmann theory of a colloid-ion mixture.

Trapping colloids near chemical stripes via critical Casimir forces [PDF]

, 2011
We study theoretically and experimentally the solvent-mediated critical Casimir force acting on colloidal particles immersed in a binary liquid mixture of water and 2,6-lutidine and close to substrates which are chemically patterned with periodically ...

Formation and stability of NOM-Mn(III) colloids in aquatic environments.

Water Research, 2019
Soluble Mn(III) species stabilized by natural organic matter (NOM) plays a crucial role in a number of biogeochemical processes. To date, current understanding of these phenomena has been primarily concerned on the occurrence and chemistry of soluble NOM-

Emergence of macroscopic directed motion in populations of motile colloids [PDF]

Nature, 2013
From the formation of animal flocks to the emergence of coordinated motion in bacterial swarms, populations of motile organisms at all scales display coherent collective motion.

Synthetic phosphoethanolamine-modified oligosaccharides reveal the importance of glycan length and substitution in biofilm-inspired assemblies

Nature Communications, 2022
The phosphoethanolamine modified cellulose in E. colibiofilms has revealed that polysaccharide functionalization alters the biofilm properties. Here, the authors show a model system to explore the role of phosphoethanolamine and other unnatural ...

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 ...

Dissolution Behavior of Simulated Co Colloid in Oxidation Operation Process during Shutdown of PWRs

Yuanzineng kexue jishu, 2022
58Co and 60Co are the primary radionuclides and contributors to collective dose of PWRs, which may exist in ionic, particle and colloidal state in the primary loop. The pore diameter of the most advanced filter used in chemical and volume control system
