Patent number: 10384372Abstract: Method for producing shaped polymeric microparticles of non-spherical shape, comprising the steps of: placing one or more microparticles of substantially spherical shape in a respective micro-cavity of a mold having the desired non-spherical shape; subjecting said microparticles to softening by exposure to a solvent or mixture of solvent/non-solvent, in the liquid or vapor state, adapted to plasticize the polymeric material constituting said microparticles, and possibly assisting the solvent plasticization process by heat treatment, not excluding the possibility, in less critical cases in terms of conservation of the microstructure, of carrying out heat treatment exclusively, at a temperature not exceeding 40% of the glass transition temperature of the polymer material; and removing said microparticles from the mold cavities.Type: GrantFiled: April 8, 2014Date of Patent: August 20, 2019Assignee: Fondazione Istituto Italiano di TecnologiaInventors: Raffaele Vecchione, Renato De Alteriis, Paolo Antonio Netti

Patent number: 9561355Abstract: There is described a method for making an array of micro-needles, comprising the steps of: depositing a plurality of drops of a liquid substance comprising a polymer on a surface of a starting substrate; positioning a pyroelectric substrate at a certain distance from the starting substrate in such a way that the drops deposited are positioned between said surface of the starting substrate and a surface of the pyroelectric substrate; varying the temperature of the pyroelectric substrate or a part thereof to induce on said surface of the pyroelectric substrate a charge density such that starting from the drops deposited, under the effect of an electrodynamic force, respective cones are formed having a tip facing towards the pyroelectric substrate; determining a consolidation of the cones, to form said micro-needles, preventing the tip of said cones from contacting said surfaces of the pyroelectric substrate.Type: GrantFiled: February 11, 2014Date of Patent: February 7, 2017Assignees: CONSIGLIO NAZIONALE DELLE RICERCHE, FONDAZIONE ISTITUTO ITALIANO DI TECNOLOGIAInventors: Pietro Ferraro, Sara Coppola, Andrea Finizio, Simonetta Grilli, Veronica Vespini, Paolo Antonio Netti, Raffaele Vecchione, Eliana Esposito

Patent number: 8852826Abstract: A composite product is for an electrode of a fuel cell including a catalyst, an electrically conductive phase which supports such catalyst, a protonically conductive phase, and a porous phase. At least the contact between the catalyst and the electrically and protonically conductive phases, and preferably also the contact of the porous phase with the catalyst and with the electrically and protonically conductive phases, is improved or maximized. Each of the phases is individually continuous, and such phases are continuous with each other.Type: GrantFiled: May 23, 2008Date of Patent: October 7, 2014Assignee: STMicroelectronics S.R.L.Inventors: Raffaele Vecchione, Salvatore Leonardi, Giuseppe Mensitieri, Anna Borriello

Publication number: 20140084519Abstract: The present disclosure relates to mold components and imprint lithography techniques applied on the basis of organic mold materials in order to form polymer microstructure elements. It has been recognized that adapting surface characteristics of at least one mold component may significantly enhance performance of the lithography process, in particular with respect to suppressing residual polymer material, which in conventional strategies may have to be removed on the basis of an additional etch process.Type: ApplicationFiled: September 18, 2013Publication date: March 27, 2014Applicants: Fondazione Istituto Italiano di Tecnologia, STMicroelectronics S.r.l.Inventors: Fabrizio Porro, Antonio Scognamiglio, Raffaele Vecchione, Valeria Casuscelli, Andrea Di Matteo, Luigi Giuseppe Occhipinti, Paolo Netti

Patent number: 8062976Abstract: A method is for forming a vertical interconnection through a dielectric layer between upper and lower electrically conductive layers of an integrated circuit. The method includes forming an opening through the dielectric layer and placing a solidifiable electrically conductive filler into the opening via a printing technique. The solidifiable electrically conductive filler is solidified to thereby form a solidified electrically conducting filler in the opening. A metallization layer is formed over the dielectric layer and the solidified electrically conducting filler to thereby form the vertical interconnection through the dielectric layer between the upper and lower electrically conductive layers of the integrated circuit.Type: GrantFiled: July 27, 2010Date of Patent: November 22, 2011Assignee: STMicroelectronics S.R.L.Inventors: Raffaele Vecchione, Luigi Giuseppe Occhipinti, Nunzia Malagnino, Rossana Scaldaferri, Maria Viviana Volpe
