In the ciliate Paramecium caudatum, only mating-reactive cells can attach to the polystyrene surface of Petri dishes. The attachment of mating-reactive cells occurs exclusively at the tips of ventrally located cilia (mating-reactive cilia) and appears to involve a hydrophobic interaction. An increase in the hydrophilic nature of the polystyrene surface following treatment with sulphuric acid re...

This multi-scale and multi-technique work investigates the adsorption of phosphated species on TiO 2 anatase surface. Our original approach declines for first time progressive ethyl substitution phosphates to identify structure complexes formed upon these molecules in aqueous dispersions, under various pH conditions. To quantify adsorbed amount , isotherms were recorded as a function pH. In par...

Nanoparticles are important catalysts for many chemical transformations. However, owing to their structural dispersions, heterogeneous distribution of surface sites and surface restructuring dynamics, nanoparticles are intrinsically heterogeneous and challenging to characterize in ensemble measurements. Using a single-nanoparticle single-turnover approach, we study the redox catalysis of indivi...
