  • Synthesis of ferromagnetic manganese-bismuth nanoparticles using a manganese-based ligated anionic-element reagent complex (Mn-LAERC) and formation of bulk MnBi magnets therefrom
    Patent number: 9796023
    Abstract: A method for synthesizing ferromagnetic manganese-bismuth (MnBi) nanoparticles, and the MnBi nanoparticles so synthesized, are provided. The method makes use of a novel reagent termed a manganese-based Anionic Element Reagent Complex (Mn-LAERC). A process for forming a bulk MnBi magnet from the synthesized MnBi nanoparticles is also provided. The process involves simultaneous application of elevated temperature and pressure to the nanoparticles.

  • Ligated anionic-element reagent complexes (LAERCs) as novel reagents
    Patent number: 9546192
    Abstract: A novel ligated reagent complex is provided. The ligated reagent includes at least one zero-valent atom, whether metal, metalloid, or non-metal, in complex with at least one hydride molecule and at least one nitrile compound. The ligated reagent complex can be useful in the synthesis of nanoparticles. Also provided is a method for preparing a ligated reagent complex. The method includes a step of ball-milling a mixture that includes a preparation containing a zero-valent element, a hydride molecule, and a nitrile compound.
