Abstract: A method for growing beta phase of gallium oxide (β-Ga2O3) single crystals from the melt contained within a metal crucible surrounded by a thermal insulation and heated by a heater. A growth atmosphere provided into a growth furnace has a variable oxygen concentration or partial pressure in such a way that the oxygen concentration reaches a growth oxygen concentration value (C2, C2′, C2″) in the concentration range (SC) of 5-100 vol. % below the melting temperature (MT) of Ga2O3 or at the melting temperature (MT) or after complete melting of the Ga2O3 starting material adapted to minimize creation of metallic gallium amount and thus eutectic formation with the metal crucible. During the crystal growth step of the β-Ga2O3 single crystal from the melt at the growth temperature (GT) the growth oxygen concentration value (C2, C2′, C2″) is maintained within the oxygen concentration range (SC).

Abstract: The present invention relates to an to an optical device comprising a micro-optical system and a retainer, and to a method for producing an optical device. In the case of the device according to the invention, the micro-optical system (10) is fastened in such a way that the micro-optical system is oriented in relation to a surface (50) of the retainer (60). The device is characterized in that the retainer (60) has a round, tapered recess (40) and the micro-optical system (10) is fastened on a spherical cap (20) and the spherical cap (20) is fastened to the retainer (60), wherein the spherical cap (20) at least partially protrudes into the recess (40) and lies against a partial surface (30) of the recess (40) or an edge (41) in the recess (40), wherein the spherical cap (20) is fastened to the retainer (60) in the recess (40), but is not fastened where the spherical cap lies in contact. Because the spherical cap lies in contact, shrinking of a fasting means cannot cause a shift or rotation of the spherical cap and thus cannot cause a misadjustment.

Abstract: The present invention relates to a precursor of a molecular sensor for determining analyte concentrations and/or measuring analyte concentration changes comprising a host for an active nucleus, an NMR-modulating moiety and an interacting moiety, wherein said NMR-modulating moiety changes the resonance frequency or the chemical exchange saturation transfer (CEST) signal of the active nucleus-host complex, and wherein said interacting moiety specifically responds to an environmental parameter, to an analyte or to a target molecule that binds the analyte or said interacting moiety specifically binds to a target molecule in an analyte-dependent manner. The present invention further relates to a molecular sensor comprising an active nucleus and said precursor. The present invention further relates to a molecular sensor for determining analyte concentrations and/or measuring analyte concentration changes inside a cell, wherein moiety/ies of the sensor are expressed in said cells and then assembled inside said cell. The present invention further relates to uses of the molecular sensors as well as to an in vitro method for determining metal concentration and/or measuring metal concentration changes and a method for diagnosing and/or monitoring treatment of diseases causing changes in metal concentrations.

Abstract: The present invention relates to a modulator for a digital amplifier and a device comprising such a modulator and a digital amplifier.The modulator (100) comprises a pulse shaper (110) and a control unit (120) for controlling the pulse shaper (110) to convert an input signal into a bit stream (130) configured for a digital amplifier which encodes an amplitude value per clock of a carrier signal. The pulse shaper (110) can represent a respective amplitude value of the input signal with different bit patterns. The bit pattern respectively used by the pulse shaper is determined by the control unit (120) by means of a corresponding, associated control command. The modulator (100) is characterized in that in the control unit (120) an assignment (160) of the control commands to associated amplitude values resulting from amplification of the associated bit patterns with the digital amplifier (400) is stored or at least is provided in that the control unit (120) selects a control command per clock by means of the assignment (160) and the amplitude value of the input signal and drives the pulse shaper (110) accordingly.
