Ceramic laser materials have come a long way since the first demonstration of lasing in 1964. Improvements in powder synthesis and ceramic sintering as well as novel ideas have led to notable achievements. These include the first Nd:yttrium aluminum garnet (YAG) ceramic laser in 1995, breaking the 1 KW mark in 2002 and then the remarkable demonstration of more than 100 KW output power from a YA...
The type of bearing material that should be used in revision surgery after the failure of ceramic-on-ceramic total hip arthroplasty (THA) remains controversial. In the case of ceramic fracture, the residual ceramic particles can cause consequent metallosis when metal implants are used for revision THA. On the other hand, in the case of THA failure without ceramic fracture, revision THA with a m...
This paper deals with the effect of catalyst loading on activity and selectivity CuOx−MnOy catalysts alumina-silicate supports (fiber material-Al2O3(44)/SiO2(56)). A special focus lies oxidation CO, mixtures VOC from 1-butene, isobutane, n-butane, propane, ethene, ethane, as well CO in presence NO2. The are prepared through wet impregnation filter section an aqueous solution copper manganese ni...
