摘要： The given invention is related to the field of medicine, namely to experimental research in oncology, and can be used to obtain a pharmaceutical agent for inhibiting the proliferation of HeLa cervical cancer cells. It entails the use of a metal powder obtained in a gaseous medium by means of an electric explosion of a wire made of low-carbon steel carried out with a specific energy of 7-18 kJ/g and a pulse duration of 1.2-2 μs. The explosion is carried out inside a reactor that is pre-evacuated to a residual pressure of 10−2 Pa, and then filled with carbon monoxide to a pressure of 105 Pa at a gas circulation rate flow of 10 m/s. The products of the explosion deposited in a hopper are passivated in air for at least 48 hours. The resulting powder is extracted and mixed with a solution of the RPMI-1640 nutrient medium with L-glutamine, a pH of 7.2, in the proportion of the mass of the powder to the volume of the specified solution from 1:10 to 2.7:10. The solution is then centrifuged until the phases are separated. The liquid phase is decanted and used as a pharmaceutical agent. The purpose of the given invention is to expand the arsenal of tools for inhibiting the proliferation of tumor cells.

摘要： The present disclosure provides a method for preparing a high-purity powder material, an application thereof, and a double-phase powder material. The high-purity powder material is prepared through an “atomization comminuting process and de-phasing method”. The preparation method comprises the following steps: firstly preparing intermediate alloy powders with first-phase particles wrapped by a second-phase matrix through an atomization comminuting process. Impurity elements are enriched into the second-phase matrix and the first-phase particles are purified during the solidification of the intermediate alloy powders; By removing the second-phase matrix in the intermediate alloy powders, a high-purity target powder material originated from the original first-phase particles can be obtained. The preparation method of the present disclosure has the characteristics of a simple process, easy operation, and low cost, and can be used to prepare nano-level, sub-micron-level, and micro-level multiple high-purity powder materials, which has a good application prospect in catalytic materials, powder metallurgy

Example alloy compositions may include an iron-based grain, and a grain boundary. The grain boundary may include a non-magnetic, anti-ferromagnetic, or ferrimagnetic material. Example techniques for forming iron-based core-shell nanoparticles may include depositing a shell on an iron-based core. The depositing may include immersing the iron-based core in a salt composition for a predetermined period of time. The depositing may include milling the iron-based core with a salt composition for a predetermined period of time.
