Abstract: A method for directly preparing a trivalent chromium compound by electrochemical oxidation of ferrochrome is provided. The method includes: putting ferrochrome as an anode, and placing the anode into an electrolyte solution containing a complexing agent together with a cathode, then turning on a power supply for electrolysis reaction so that chromium and iron in ferrochrome are directly converted into free Cr3+ and Fe3+ respectively, allowing one of Cr3+ and fe3+ to form a stable soluble metal complex together with the complexing agent, and allowing the other of Cr3+ and Fe3+ to form a metal hydroxide solid together with OH? generated by electrolysis reaction, so as to obtain an electrolysis completion slurry. Compared with the prior art, the present application has no hexavalent chromium salt stage, thereby shortening the process flow and avoiding the generation of chromium-containing waste residue.

Abstract: Methods provided by the present disclosure utilize extracorporeal shockwaves, mechanical impacts and/or principles of lithotripsy to break up a tissue sample into smaller fragments—clusters of cells and/or single cells—after which a desired cellular fraction can be isolated from the sample. Devices provided by the present disclosure deploy focused and/or directed shockwaves, and/or focused and directed mechanical impacts, to break apart a tissue sample. The devices maintain the sample in a sterile, closed environment during exposure to the shockwaves or mechanical impacts. Therefore, the shockwaves and/or mechanical impacts are generated outside of a closed device and are transmitted through one or more walls of the device into its interior, where the sample is located.
