Patent number: 7928368Abstract: The invention relates to an electrospray ionization (ESI) device for forming a stream of ionized sample molecules. The device comprises a sample introduction zone for receiving a liquid-form sample, a tip for spraying the sample into aerosol or gaseous form, and a flow channel connecting the sample introduction zone and the tip. According to the invention, the flow channel comprises an array of transversely oriented microstructures adapted to passively transport the liquid-form sample introduced to the sample introduction zone to the tip by means of capillary forces. The invention concerns also a manufacturing method and applications of the ESI device, in particular mass spectrometry.

Patent number: 7863559Abstract: A method and an apparatus for examining a sample by means of mass spectrometry. According to the method, the solution comprising the sample to be examined is vaporized in a vaporizer, the vaporized sample solution is sprayed, using a gas flow, into a corona discharge zone, where the examined sample is ionised according to the APCI method, using a corona discharge, to generate gas phase ions, and the ions are separated and directed to a detector. According to the present invention, a vaporizer is used, which is fabricated as a micromechanical structure which comprises the flow channels for the solution and for the carrier gas possibly used for feeding the solution, as well as the heater of the vaporizer, and which are all included in a monolithic structure. The solution is especially suitable for cases in which a very sensitive analysing technique is needed, or in which the available sample quantity is very small (less than 1 ?L).Type: GrantFiled: November 15, 2004Date of Patent: January 4, 2011Assignee: Licentia OyInventors: Risto Kostiainen, Samuli Franssila, Tapio Kotiaho, Seppo Marttila

Publication number: 20080149160Abstract: A photovoltaic device and a method for production thereof. The photovoltaic device comprises an anode (32), a cathode (46) spaced apart from the anode, and at least one subcell disposed between the anode and the cathode. The subcell comprises a charge-transfer dyad (38) with a light absorbing electron donor moiety (40) and an electron acceptor moiety (42), which are covalently linked to each other in a non-flexible configuration and oriented such that each subcell is capable of performing primary photo-induced vectorial electron transfer between the donor and acceptor moieties in the direction from the anode to cathode. The structure of the donor-acceptor molecule is highly symmetric, which greatly increases the intramolecular electron transfer probability and, thereby, the efficiency of the device.Type: ApplicationFiled: August 18, 2005Publication date: June 26, 2008Applicant: LICENTIA OYInventors: Helge Lemmetyinen, Nikolai Tkachenko, Alexander Efimov, Elina Vuorimaa, Tommi Vuorinen, Vladimir Chucharev
