Patent number: 11065688Abstract: The invention relates to nano-particles comprising metallic ferromagnetic nanocrystals combined with either amorphous or graphitic carbon in which or on which chemical groups are present that can dissociate in aqueous solutions. According to the invention there is provided nano-particles comprising metal particles of at least one ferromagnetic metal, which metal particles are at least in part encapsulated by graphitic carbon. The nano-particles of the invention are prepared by impregnating carbon containing bodies with an aqueous solution of at least one ferromagnetic metal precursor, drying the impregnated bodies, followed by heating the impregnated bodies in an inert and substantially oxygen-free atmosphere, thereby reducing the metal compounds to the corresponding metal or metal alloy.Type: GrantFiled: February 15, 2017Date of Patent: July 20, 2021Assignee: BASF CORPORATIONInventors: Leonardus Wijnand Jenneskens, John Wilhelm Geus, Bernard Hendrik Reesink, Pieter Hildegardus Berben, Jacobus Hoekstra

Publication number: 20180180330Abstract: The invention relates to a magnetocaloric lattice element formed by fibres of magnetocaloric material, wherein the fibres are arranged in respective parallel lattice planes, each fibre having a respective mass of magnetocaloric material, the fibres of a given lattice plane do not contact each other but each fibre of a given lattice plane is attached to at least two fibres in a next neighbouring lattice plane, and wherein the magnetocaloric lattice element exhibits exactly one predominant mass-weighted direction of longitudinal fibre extension. When arranged in alignment of its predominant mass-weighted direction of longitudinal fibre extension with an external magnetic field, the magnetocaloric lattice element achieves an advantageous, particularly high magnetization of the magnetocaloric material, and as a consequence improves the performance of the magnetocaloric cooling device.Type: ApplicationFiled: June 8, 2016Publication date: June 28, 2018Applicant: BASF SEInventors: Florian SCHARF, Lian ZHANG, Bernard Hendrik Reesink, David VAN ASTEN
