The invention relates to sulfonated aminomethylated chelate resins, to a method for producing same, to the use thereof for obtaining and purifying metals, in particular rare earth metals, from aqueous solutions and organic liquids, and for producing highly pure silicon.

The present disclosure relates to processes for recovering rare earth elements from an aluminum-bearing material. The processes can comprise leaching the aluminum-bearing material with an acid so as to obtain a leachate comprising at least one aluminum ion, at least one iron ion, at least one rare earth element, and a solid, and separating the leachate from the solid. The processes can also comprise substantially selectively removing at least one of the at least one aluminum ion and the at least one iron ion from the leachate and optionally obtaining a precipitate. The processes can also comprise substantially selectively removing the at least one rare earth element from the leachate and/or the precipitate.

A quantum dot has a fluorescent crystalline nanoparticle, wherein the quantum dot has a core-shell structure including a core particle containing a first metal element and a shell layer containing a second metal element, at an interface between the core particle and the shell layer, a third metal element different from the first metal element and the second metal element is present, and an amount of the third metal element with respect to an amount of the first metal element contained in the core particle is 10% or less in terms of molar ratio. As a result the quantum dot has excellent controllability of the emission wavelength and high luminous properties and luminous efficiency.

A biomimetic synthesis of antihyperglycemic nanoparticles using silver nitrate and Lavatera cretica is a method for the green synthesis of silver nanoparticles. These nanoparticles may be produced by extraction of fresh L. cretica leaves and mixing and incubation of the resulting L. cretica extract with silver nitrate to produce a nanoparticle composition including the silver nanoparticles. The nanoparticle composition may protect against hyperglycemia.
