We discuss the peculiarities of Seebeck effect in stabilized electrolytes containing colloidal particles. Its unusual feature is two stage character, with linear increase differential thermopower as function particles concentration n⊙ during first (“initial state”) and dramatic drop it at small second one (“steady state”). show that properties initial state are governed by thermo-diffusion flow...

A new, efficient method for the characterization of magnetic colloids based on the Faraday effect is proposed. According to the main principles of this technique, it is possible to detect the stray magnetic field of the colloidal particles induced inside the magnetooptical layer. The magnetic properties of individual particles can be determined providing measurements in a wide range of magnetic...

The net charge of a colloidal particle was controlled using light and a new photocleavable self-assembled monolayer (SAM). The SAM contained a terminal ammonium group and a centrally located carboxylic acid group that was masked with an ortho-nitrobenzyl functionality. Once exposed to UV light, the 2-nitrobenzyl group was cleaved, therefore transforming the colloidal particle from a net positiv...
