Abstract Anisotropic deformation of colloidal particles was investigated under ion irradiation with 4 MeV Cu ions. In this study, 0.5 μ m-diameter silica particles, Au-silica core–shell and 15 nm-diameter Au colloids embedding in a planar Si/SiO 2 matrix were irradiated ions at room temperature normal incidence. beam causes dramatic anisotropic deformation; expands perpendicular to the contract...

Ion-adsorption-type rare earth ores (IREOs) are an indispensable strategic resource. Rare earths can be extracted from IREOs by means of in situ leaching, which is strongly influenced the migration clay components. In order to clarify effect interaction between mineral particles on leaching process, aggregation IREO colloids was investigated suspension after NaCl concentration and pH value were...

The solid-liquid phase-diagram of charge-stabilized colloidal suspensions is calculated using a technique that combines a continuous Poisson-Boltzmann description for the microscopic electrolyte ions with a molecular-dynamics simulation for the macroionic colloidal spheres. While correlations between the microions are neglected in this approach, many-body interactions between the colloids are f...

– Twoand three-particle correlation functions are computed from video-microscopy data of two-dimensional suspensions of charged colloids and inverted to derive the pair and three-body interaction potentials between the colloidal particles. Our method allows to resolve the full spatial dependence of the three-body potentials. Examining colloidal systems at different colloid densities, we find de...
