In the present work, the effect of Ca(NO3)2.4H2O and (NH4)2HPO4 primary solutions as the beginning materials in synthesis of a calcium phosphate phase, was examined. So, we investigated the wet chemical reactions in solution at different temperatures by a hydrothermal condition aimed at hydroxyapatite (Ca10(PO<su...

Atomic force microscope (AFM) observation and analysis of Izumiyama hydrothermal illite (the weaker altered illite-kaolinite zone (IZ-1) and the higher altered illite zone (IZ-2)) were performed to understand the crystal growth mechanism and the relation between morphology and polytype of the illites. Our AFM results suggest that growth of the Izumiyama illite was controlled by a mechanism of s...

The microflora developing during a continuous enrichment culture from a hydrothermal chimney sample was investigated by molecular methods. The culture was performed in a gas-lift bioreactor under anaerobic conditions, at 90°C and pH 6.5, on a complex medium containing sulfur as the terminal electron acceptor. Archaeal and bacterial diversity was studied. Microorganisms affiliated with the gener...
