    Abstract: In an embodiment, the present disclosure pertains to a method of making magnetic nanoparticles through the utilization of a microfluidic reactor. In some embodiments, the microfluidic reactor includes a first inlet, a second inlet, and an outlet. In some embodiments, the method includes applying a magnetic nanoparticle precursor solution into the first inlet of the microfluidic reactor through a first flow rate and applying a reducing agent into the second inlet of the microfluidic reactor through a second flow rate. In some embodiments, the magnetic nanoparticles are produced in the microfluidic reactor and collected from the outlet of the microfluidic reactor. In an additional embodiment, the present disclosure pertains to a composition including a plurality of magnetic nanoparticles. In a further embodiment, the present disclosure pertains to a microfluidic reactor.

    Abstract: Disclosed is a cartridge case for various caliber ammunition that can consist essentially of a powdered metal and/or powdered metal alloy(s) that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding (“MIM”) processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. Also disclosed are embodiments related to a case telescoped cartridge that may include a cap and a body. The body can consist essentially of or consists entirely of a powdered metal and/or powdered metal alloy(s) that has been formed through MIM. The cap can comprise plastic that has been formed through plastic molding or comprise powdered metal and/or powdered metal alloy(s) that has been formed through MIM.
