Peter J Polesnak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and apparatus for synthesis and magnetophoretic fractionization size-selection of magnetic nanoparticles from a solution
    Patent number: 11673813
    Abstract: Methods and apparatus for producing a magnetic nanoparticle suitable for additive manufacturing techniques includes providing a solution having a plurality of metallic precursors to produce magnetic nanoparticles, a coordinating solvent, and a chelating agent. The solution is mixed and heated to grow nanoparticles wherein magnetic nanoparticles are formed. The solution is then cooled and a magnetic field is applied to the solution wherein ferrite nanoparticles are at least partially separated by size.
    Type: Grant
