Patent number: 9005569Abstract: A microstructure that can develop non-conventional and novel physical properties and a method for producing the same are provided. Ethanol is added to a mixture solution produced by adding a surfactant solution to a peroxotitanic acid aqueous solution to produce precipitates, and the precipitates collected from the mixture solution are let dried to produce precursor powders 5. The precursor powders 5 are calcined at a predetermined temperature. Accordingly, a microstructure 2 can be produced which is formed of monophasic Ti4O7 in nano size. The microstructure 2 of monophasic Ti4O7 produced in this fashion can be fine-grained in nano size unlike prior-art crystals.Type: GrantFiled: November 19, 2010Date of Patent: April 14, 2015Assignee: The University of TokyoInventors: Shin-ichi Ohkoshi, Deepa Dey, Yoshihide Tsunobuchi, Kazuhito Hashimoto, Hiroko Tokoro, Fumiyoshi Hakoe

Publication number: 20150072863Abstract: Known processes for the production of nanoparticles of compounds of the transition metals Zr, Ti, Ta, rare earths (RE), Mn, and Fe via microemulsions lead to products that contain impurities from the reactants, particularly water, which make the further use of said nanoparticles difficult, for instance in high-temperature super conductors (HTSC). It is proposed that the nanoparticles be produced via anhydrous microemulsions having an outer phase composed of a nonpolar solvent and inner phase composed of a polar anhydrous solvent. The nanoparticles thus obtained exhibit good monodispersity and can be used in the production of REBa2Cu3O7 super conductors by incorporation into the precursor coating solution.Type: ApplicationFiled: March 20, 2013Publication date: March 12, 2015Applicant: BASF SEInventors: Thomas Freudenberg, Bernhard Holzapfel, Oliver Brunkahl, Michael Baecker

Patent number: RE48454Abstract: A continuous flow reactor for the efficient synthesis of nanoparticles with a high degree of crystallinity, uniform particle size, and homogenous stoichiometry throughout the crystal is described. Disclosed embodiments include a flow reactor with an energy source for rapid nucleation of the procurors following precursors to form nucleates followed by a separate heating source for growing the nucleates. Segmented flow may be provided to facilitate mixing and uniform energy absorption of the precursors, and post production quality testing in communication with a control system allow automatic real-time adjustment of the production parameters. The nucleation energy source can be monomodal, multimodal, or multivariable frequency microwave energy and tuned to allow different precursors to nucleate at substantially the same time thereby resulting in a substantially homogenous nanoparticle. A shell application system may also be provided to allow one or more shell layers to be formed onto each nanoparticle.Type: GrantFiled: August 1, 2018Date of Patent: March 2, 2021Inventors: David M.
