1. Zirconium dioxide based dental restorations : studies on clinical survival and fracture behaviour
Abstract : POPULÄRVETENSKAPLIG SAMMAN-FATTNINGAtt förlora tänder påverkar en människas utseende och funktioner såsom tal och tuggning. Det finns därmed ett behov att rehabilitera och ersätta förlorade tänder för att upprätthålla en god livskvalitet. READ MORE

2. Porous Cerium Dioxide for Catalytic Applications
Abstract : Mesoporous cerium dioxide with high crystallinity has been synthesized and studied by TEM, SEM, nitrogen adsorption, PXRD, AFM, and SAXS. The catalytic properties of the materials have been investigated The results of the catalysis experiments were correlated with high resolution TEM investigations of the corresponding material, and it was found that the exposed crystallographic facets play an important role in the conversion of carbon monoxide to carbon dioxide.

4. Monolithic and semi-monolithic translucent zirconium-dioxide restorations : aspects on design, material and strength
Abstract : Although many clinical reports have shown high rates of clinical success associated with fixed dental restorations made of traditional zirconium-dioxide (zirconia), clinical failure due to improper design aiming to achieve high strength and optimal aesthetics, still occurs. Previous clinical and laboratory studies indicated that veneering porcelain and the connector represent the weak parts of the fully-veneered zirconia restorations where failure may occur. READ MORE

5. RhPt and Ni based catalysts for fuel reforming in energy conversion
Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE
