Patent number: 9437753Abstract: A device includes a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. The electrical contacts (14) include conductive seeds (16) deposited on the conductive surface (12), an electrically insulating layer (18), which covers discontinuously the conductive seeds (16) in order to form openings leaving access to the conductive seeds (16), and a plating layer (22) recovering the discontinuous insulating layer (18) and deposited on conductive seeds (16) which are accessible through the openings and form points from which the deposit of the plating layer (22) can start. The rest of the conductive surface (12), which doesn't include any electrical contacts (14), is continuously covered by the electrically insulating layer (18).Type: GrantFiled: October 11, 2010Date of Patent: September 6, 2016Assignee: ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE (EPFL) EPFL-TTOInventor: Christophe Ballif

Patent number: 9324505Abstract: The invention relates to substituted ullazine and analogs of ullazine as sensitizers for dye-sensitized solar cells (DSSCs) and other photoelectrochemical and/or optoelectronic devices. The sensitizers may comprise donor substituents and/or acceptor substituents, besides an anchoring group suitable for attaching the sensitizer on a semiconductor surface. DSSCs based on this type of sensitizers exhibit high power conversion efficiencies.Type: GrantFiled: October 18, 2011Date of Patent: April 26, 2016Assignee: Ecole Polytechnique Federale de Lausanne (EPFL) EPFL-TTOInventors: Jared Delcamp, Michael Graetzel, Mohammad Khaja Nazeeruddin

Patent number: 9086465Abstract: A method for high resolution NMR (=nuclear magnetic resonance) measurements using the application of excitation pulses and the acquisition of data points, whereby a dwell time ?t separates the acquisition of two consecutive data points, which is characterized in that one or more tickling rf (=radio frequency) pulses of duration ?p are applied within each dwell time ?t, and that the average rf field amplitude of each of the tickling rf pulses approximately fulfills the condition ?1=?1?p/?t=?J wherein J is the scalar J-coupling constant and ?1=?B1 with ? being the gyromagnetic ratio and B1 being the strength of the magnetic component of each tickling rf pulse. This method is effective in decoupling homonuclear couplings.Type: GrantFiled: July 11, 2012Date of Patent: July 21, 2015Assignees: Bruker BioSpin AG, Ecole Polytechnique Fédérate de Lausanne EPFL-TTOInventors: Geoffrey Bodenhausen, Diego Carnevale
