Contrasting Fluids in the Svetlinsk Gold-Telluride Hydrothermal System, South Urals

Hydrothermal synthesis of single-crystalline antimony telluride nanobelts.

The single-crystalline Sb2Te3 nanobelts were successfully synthesized by a novel and convenient surfactant-assisted hydrothermal approach. The ionic surfactant AOT acted as the shape controller in the synthetic process. We believe that this synthetic route could be applied to obtain other low-dimensional semiconducting telluride nanostructures.

The origin of methanethiol in midocean ridge hydrothermal fluids.

Simple alkyl thiols such as methanethiol (CH3SH) are widely speculated to form in seafloor hot spring fluids. Putative CH3SH synthesis by abiotic (nonbiological) reduction of inorganic carbon (CO2 or CO) has been invoked as an initiation reaction for the emergence of protometabolism and microbial life in primordial hydrothermal settings. Thiols are also presumptive ligands for hydrothermal trac...

Estimation of Gold in Biological Fluids.

Chrysotherapy has now become a recognized form of treatment in rheumatoid arthritis and much experimental work has been done to determine the fate of gold salts in the body. Kling and his colleagues (1939) showed that gold compounds were deposited mainly in reticulo-endothelial cells, of which synovial membrane contains a large number. They were able to detect spectrographically the presence of...
