Provided is a method for processing electronic and electrical device component scrap, which can improve an efficiency of sorting of raw materials fed to the smelting step from electronic and electrical device component scrap, and reduce losses of valuable metals. A method for processing electronic and electrical device component scrap which includes sorting electronic and electrical device component scrap by wind powder sorting to remove plate-shaped materials containing valuable metals included in the electronic and electrical device component scrap, and then sorting the resulting sorted objects by magnetic sorting.

The present disclosure provides a superparamagnetism-modified and neutrophil exosome biomimetic vesicle-based biological preparation for drug delivery, and a preparation method thereof, belonging to the technical field of engineered nanovesicle drug loading systems. The superparamagnetism-modified and neutrophil exosome biomimetic vesicle-based biological preparation for drug delivery prepared by the preparation method acts on tumor cell lines. It is found that the superparamagnetism-modified and neutrophil exosome biomimetic vesicle-based biological preparation for drug delivery can specifically target tumor cells, induce tumor cell apoptosis, and inhibit tumor growth. The biological preparation significantly extends a survival time of mice and improves an efficacy of drugs against cancers.

A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility.

A magnetic stand includes: a base having an insertion hole into which a container is to be inserted, the insertion hole extending along a first axis; and a magnet provided on the base and having a magnetization that applies a magnetic field to the insertion hole. The magnet is disposed such that magnetic poles thereof face directions different from that of the container. When a plane including the first axis and determined such that a normal line of the plane is orthogonal to the first axis and passes through a center of the magnet is taken as a reference plane, and the magnetization is projected onto the reference plane, an angle formed by the first axis and the magnetization projected onto the reference plane is more than 0° and 90° or less.
