TL;DR: Room-temperature ionic liquids with the tris(pentafluoroethyl)trifluorophosphate anion in contact with a charged sapphire substrate were investigated with submolecular resolution and showed strong interfacial layering, akin to the charge inversion effect.
Journal ArticleDOI
Differential Capacitance of the Electrical Double Layer in Imidazolium-Based Ionic Liquids: Influence of Potential, Cation Size, and Temperature
TL;DR: In this paper, the interfaces formed at glassy carbon electrodes in three low-temperature ionic liquids (1-methyl-3-ethylimidazolium chloride, emimCl, bmimCl; and 1-methyl 3-hexy-limidaxolium-chloride (HmCl), hmCl) were investigated by cyclic voltammetry and impedance spectroscopy.
Journal ArticleDOI
Functionalized gold nanoparticles: Synthesis, structure and colloid stability
TL;DR: Five areas are reviewed: synthesis and applications of nanostructured particles; formation and structure of self-assembled monolayer protected gold nanoparticles; colloid stability-DLVO and non-DL VO forces; photochemistry, photochromism and pyrimidine; and manipulation of colloid Stability with external stimuli.
Journal ArticleDOI
The limits of fine particle flotation
TL;DR: In this article, the influence of bubble size, particle aggregation, different flow conditions, particle induction time, as well as the action of surface and capillary forces on fine particle-bubble capture is discussed.
Journal ArticleDOI
Particle–bubble collision models — a review
TL;DR: A critical review of the various models existing in the literature for the calculation of the collision efficiency between particles and single, rising gas bubbles is presented and the differences in collision efficiencies obtained were mainly explained in terms of the degree of mobility of the bubble surface.
