Title: Marc L Kullberg: Innovator in Superconductors and Catalysis
Introduction
Marc L Kullberg is a notable inventor based in Lisle, IL (US). He holds a total of 3 patents that showcase his contributions to the fields of superconductors and catalysis. His innovative work has significantly impacted the development of advanced materials and processes.
Latest Patents
One of Kullberg's latest patents focuses on enhancing the fracture toughness of copper oxide superconductors. This invention involves the addition of an oxide-based strengthening agent, specifically tetragonal ZrO₂ particles, to superconducting YBa₂Cu₃Oₓ (123). The incorporation of a non-reactive sol-gel coating minimizes adverse reactions between the superconductor and the toughening agent, resulting in a composite with a fracture toughness (Kₐₐ) of 4.5 MPa(m)⁰.⁵.
Another significant patent pertains to a catalyst and process for the oxidative dehydrogenation of lower-alkyl-monosubstituted ethylbenzene to lower-alkyl-monosubstituted styrene. This invention utilizes barium pyrophosphate and a specific calcination product of KFe₃H₁₄(PO₄)₈.nH₂O as effective catalysts. The process operates at low temperatures, ensuring minimal cracking of the lower alkyl group, which enhances conversions and selectivities to the desired styrenes.
