Research reactors currently rely on thermocouples for accurate temperature measurements in instrumented rigs. However, a lot of irradiations are carried out in lower cost instrumented capsules without instrumentation where thermocouples are not an option. In the latter case calculations or melt wires are used to determine the irradiation temperatur...

During the joint research project a pilot system for the fabrication of thin-film solar modules consisting of crystalline silicon on heat resistant ceramic substrates has been set up. The following processes for the module fabrication on large areas have been developed: (1) A CVD deposition process for SiC-barrier layers on ceramics and areas up to...
In the presented work an investigation has been made of the structural and mechanical properties of monolayered and multilayered thin films in the system B-C-N-Si. The aim was to compare the properties of the monolayers with the multilayer systems to prove the potential of the mostly covalently bonded multilayer thin films. The thin films were prod...
the aim of this thesis was the comprehensive X-ray characterization of germanium nanocrystallites on and in silicon carbide substrates. on a 6H-SiC wafer by means of MBE technique Ge nanoparticles were grown. In the studied sample crystallites were detected in two orientations, which were relatively to c-axis of the 6H-SiC substrate left angle 111 ...

Hot operating bearings for use in brick kilns at temperatures up to 1000 C were investigated. It was found that none of the ceramics investigated was to be favoured, but that combinations of any two materials have the advantage that one bearing part can be designed selectively for wear. Evaluations of measurements of the friction momentum showed th...
