Inventor: HOLZ THOMAS
IPC: G01N23/207
Filed: 1999-07-06
Abstract: The invention relates to a device for X-ray fluorescence analysis wherein X-radiation of an X-ray source is directed upon a sample arranged on a sample carrier, and the fluorescence radiation is measured by a detector. On that occasion, the detection sensitivity, in particular, with respect to the total reflection X-ray fluorescence (TXRF) is to be increased for the most different samples. In order to solve this problem the sample to be analysed is placed on a multi-layer system, or a fluidic sample flows over such a multi-layer system. The multi-layer system consists of at least two or several individual layers which are arranged in a periodically repeating manner. Adjacent individual layers consist of materials having a different x-ray optical refractive index wherein the period thickness d in the multi-layer system and the angle of incidence theta of the X-radiation meet the BRAGG relationship at the used wavelength lambd of X-radiation.
Patent DE-19941282-A1 (DE)
Inventor: TIETZ FRANK
IPC: H01M8/0204
Filed: 1999-08-31
Abstract: The invention relates to temperature resistant, electroconductive connections between a ceramic and a metallic component. Said connections are produced with a sintered, electroconductive paste. The relatively low sintering temperatures for ceramics mean that only material types with a comparatively low melting point can be used. Cuprates with melting points between 800  DEG C and 1400  DEG C are particularly suitable. According to the inventive method, a paste comprising a cuprate material is applied to an interconnector by doctoring. The interconnector with the applied paste is then sintered together with other fuel cell components and connected to the same. The joining process can be matched to the glass solder used for gas sealing by choosing the appropriate cuprate.
