An inexpensively manufacturable arrangement for the cooling of thermally highly loaded components, for example the combustion chamber of a gas turbine, comprises cavities (4) provided on the thermally loaded inner surface / air exit side (3) of the wall (1) of the component which are supplied with a cooling medium from the outer surface / air inlet side (5) via cooling air openings (6) and which are covered by a heat resistant wire mesh (7) of a certain permeability. The cavity, which acts as pressure accumulator, forms, in connection with the wire mesh, a uniform pressurized-air film (8) for the cooling and heat shielding of the wall surface.

A solar cell and a method for producing a solar cell are described, comprising at least one photovoltaic layer region (1) which at least partially absorbs photons (6) incident therein, whose photon energy is greater than a minimum photon energy Emin, and releases electrical charge carriers in the form of electron-hole pairs, which are spatially separable within the photovoltaic layer region (1) and can be tapped via at least two electrodes (2), which are electrically connected to the photovoltaic layer region (1), to implement an electrical voltage, and comprising at least one interaction layer (3 and / or 4), which at least partially overlaps the photovoltaic layer region, in which at least a part of the incident photons (6) are subject to an interaction with emission of photons of higher or lower photon energy than that of the incident photons. The invention is distinguished in that the at least one interaction layer (3 and / or 4) has a matrix structure, in which locally delimited areas having optically active material, which has the structure and size of crystalline nanoparticles, are provided and interact with the incident photons (6).

A battery cell arrangement having a battery cell which is in the form of a film cell and includes a flat cell body with two end faces, a flexible cell rim surrounding the cell body, and two contact sections arranged on a rim side of the battery cell. The battery cell arrangement further has a frame arrangement which includes a first frame element and a second frame element which frames the cell body on all sides on the rim. At least one vent opening is provided on a side of the frame arrangement which faces away from the end faces of the cell body, in order to allow fluid, in particular gas, to emerge from the battery cell arrangement in the event of damage.

The present invention relates to a configuration and a method for localizing the geographic position of a person. The localization configuration comprises a transmission unit (5, 6, 7) connectable to the person, as well as a reception unit (1) for displaying the location of the person. The present invention is distinguished in that the transmission unit (5, 6, 7) comprises a GPS receiver and is connectable via wireless communication to the reception unit (1). The present invention allows both high precision in localization and also position ascertainment over great distances. The method and the cost-effectively producible device may also be used by lay people easily.

A turbine (100) of a turbine installation, especially a steam turbine of a steam turbine installation, includes at least one radial or diagonal turbine stage (120) with radial or diagonal inflow and axial outflow, and also at least one axial turbine stage (121-125) with axial inflow and axial outflow. The at least one radial or diagonal turbine stage (120) forms the first stage of the turbine (100) and the at least one axial turbine stage (121-125) is arranged downstream of the radial or diagonal turbine stage (121) as an additional stage of the turbine. The at least one radial or diagonal turbine stage (120) has a higher temperature resistance than the at least one axial turbine stage (121-125). The turbine (100) makes it possible to significantly increase the process temperature of the steam turbine installation, wherein measures for increasing the temperature resistance need only to be adopted for components of the radial or diagonal turbine stage (120).

The invention relates to a centrifuge cup, which has a container and a cover. The cover has a lever including a guide element in each case on opposing edge areas thereof. The guide elements are able to be introduced into an associated guide path of the container by pivoting the lever. The guide elements are implemented in such a way that in a closed state of the cover with the container, a clamping force (F) having vertical force component (Fy) and horizontal force component (Fx) is provided at a contact point or a contact line of the guide elements with the particular associated guide path.
