The possibility to directly write electrically conducting channels in a desired position rutile TiO2 devices equipped with asymmetric electrodes—like memristive devices—by means of the X-ray nanopatterning (XNP) technique (i.e., intense, localized irradiation exploiting an nanobeam) is investigated. Device characterization carried out by multitechnique approach involving fluorescence (XRF), exc...

Telescopic crowns are used to connect removable dental prostheses with the remaining dentition. Several material combinations are used for manufacturing primary and secondary crowns. The present experimental study analysed the influence of different material combinations on the long-term development of surface roughness and pull-off forces. Six different material combinations were tested. Secon...
