Publication number: 20130184565Abstract: A hyperpolarized liquid contrast agent is for use in a MRT device. The liquid contrast agent passes through a conduit of a MW resonator in the magnetic field of the MRT device. A microwave with a frequency of at least 40 GHz couples into the MW resonator for polarizing the liquid contrast agent upon passage through the conduit in the MW resonator using DNP. The contrast agent is polarized in a continuous passage in the MW resonator and administered immediately. A MW mode is formed in the MW resonator which has an antinode in the magnetic field strength and a node in the electric field strength. The power of the introduced microwave and coupling of the microwave into the resonator are adjusted such that in the area of the line, an amplitude of the MW magnetic field strength B1?1.5·10?2 Ts 1/T1,e results, wherein T1,e is the relaxation time of the DNP-active electrons.Type: ApplicationFiled: December 20, 2012Publication date: July 18, 2013Applicant: Johann Wolfgang Goethe-Universitat Frankfurt am MainInventor: Johann Wolfgang Goethe-Universitat Frankfurt am Main

Patent number: 8330111Abstract: The present invention relates to a device for detecting millimeter waves, having at least one field effect transistor with a source, a drain, a gate, a gate-source contact, a source-drain channel, and a gate-drain contact. Compared to a similar such device, the problem addressed by the present invention, among others, is that of providing a device which enables the provision of a field effect transistor for detecting the power and/or phase of electromagnetic radiation in the Thz frequency range. In order to create such a device, it is suggested according to the invention, that a device be provided which has an antenna structure wherein the field effect transistor is connected to the antenna structure in such a manner that an electromagnetic signal received by the antenna structure in the THz range is fed into the field effect transistor via the gate-source contact, and wherein the field effect transistor and the antenna structure are arranged together on a single substrate.Type: GrantFiled: December 12, 2008Date of Patent: December 11, 2012Assignee: Johann Wolfgang Goethe-Universitat Frankfurt A.M.Inventors: Erik Öjefors, Peter Haring Bolivar, Hartmut G.

Patent number: 8063194Abstract: The present invention relates to a polypeptide which has a novel specific arabinose transporter function as well as to nucleic acids coding therefore. The invention further relates to host cells, in particular modified yeast strains which contain the coding nucleic acids and express the polypeptide and functionally integrate it into the plasma membrane and are thus able to absorb L-arabinose. When using modified host cells which express additional proteins of the arabinose metabolic pathway, arabinose can be fermented by these cells, in particular into ethanol. The present invention is therefore relevant, inter alia, in connection with the production of biochemicals from biomass, such as bioethanol for example.Type: GrantFiled: December 7, 2007Date of Patent: November 22, 2011Assignee: Johann Wolfgang Goethe-Universität Frankfurt Am MainInventors: Eckhard Boles, Marco Keller

Publication number: 20110254610Abstract: The invention relates to devices comprising field effect transistors to detect the power of an electromagnetic high frequency signal VRF. According to the prior art, the high frequency signal is coupled into the gate G and via a capacitor CGD into the drain D of the field effect transistor FET, the gate G being biased with a direct voltage Vg which corresponds to the threshold value of the FET transistor. The resulting current at the source S contains a direct current portion Ids which is proportional to the square of the amplitude of the high frequency signal. The operating frequency of said power detectors is limited to a few gigahertz (GHz) by the discrete arrangement and especially by the predetermined gate length of the field effect transistor. The aim of the invention is to improve a resistive mixer in such a manner that it can be operated at high gigahertz and terahertz frequencies.Type: ApplicationFiled: August 28, 2009Publication date: October 20, 2011Applicants: BERGISCHE UNIVERSIT??T WUPPERTAL, JOHANN WOLFGANG GOETHE-UNIVERSITAT FRANKFURT A.M.Inventors: Ullrich Pfeiffer, Erik Oejefors, Hartmut G.

Publication number: 20110234101Abstract: The invention relates to an induction switch comprising a discharge container filled with gas and a coaxially interleaved electrode device, and to a corresponding method for commutating high voltages. The inductive production of a dense plasma and the subsequent flooding of an electrode gap with the plasma ions produced enables the commutation of high currents in the kiloamp range when there are blocking voltages of over 500 kV. Such an induction switch only requires a single discharge gap, can be used over a very wide voltage range, and avoids the problem of electrode erosion as a result of the electrode-free energy coupling.Type: ApplicationFiled: September 17, 2009Publication date: September 29, 2011Applicant: Johann Wolfgang Goethe-Universitat Frankfurt am MainInventors: Christian Teske, Joachim Jacoby
