Metal alloy nanoparticle synthesis via self-assembled monolayer formation and ultrasound
Methods and assemblies for the construction of liquid-phase alloy nanoparticles are presented. Particle formation is directed by molecular self-assembly and assisted by sonication. In some embodiments, eutectic gallium-indium (EGaIn) nanoparticles are formed. In these embodiments, the bulk liquid alloy is ultrasonically dispersed, fast thiolate self-assembly at the EGaIn interface protects the material against oxidation. The assembly shell has been designed to include intermolecular hydrogen bonds, which induce surface strain, assisting in cleavage of the alloy particles to the nanoscale. X-ray diffraction and TEM analyses reveal that the nanoscale particles are in an amorphous or liquid phase, with no observed faceting.

Solid-liquid phase reactor for preparing powder product
The present disclosure relates to the field of reactor technologies and in particular to a solid-liquid phase reactor for preparing a powder product, which includes a vessel shell, a material-restricting partition net, a solid reactant charge opening, and a reaction solution make-up opening. The material-restricting partition net is disposed in a cavity of the vessel shell and connected to the vessel shell. The material-restricting partition net is enclosed to form a semi-closed material-restricting zone with an upward-facing opening itself or together with an inner wall of a vessel. A frame of the semi-closed material-restricting zone is rigid. The solid reactant charge opening is in communication with the facing-up opening of the semi-closed material-restricting zone, and the reaction solution make-up opening is in communication with an internal space of the semi-closed material-restricting zone.

Reaction method for reacting reaction object with liquid containing the reaction object being in contact with granular porous body
A method for reacting a reaction object with a liquid containing the reaction object in contact with a granular porous body. The upper limit D (mm) of the particle diameter of the granular porous body is determined from D=0.556LN(T)+0.166 in a column flow method in non-circulation type, and determined from D=0.0315T+0.470 in the column flow method in a circulation type and a shaking method. The granular porous body includes a skeleton body including an inorganic compound having a three-dimensional continuous network structure, and has a two-step hierarchical porous structure including through-holes formed in voids in the skeleton body and pores extending from a surface to an inside of the skeleton body and dispersed on the surface. A functional group having affinity with the metal ion is chemically modified on a surface of the granular porous body.
