Abstract The recently discovered massive and stockwork sulphide mineralization of Semblana-Rosa Magra Monte Branco, situated ESE the Neves–Corvo volcanogenic (VMS) deposit in Iberian Pyrite Belt (IPB) is presented. Geological setting tectonic model discussed based on proxies such as palynostratigraphy U–Pb zircon geochronology. found within IPB Volcano-Sedimentary Complex (VSC) Lower sequence, ...

The cell association of copper in the yeast Saccharomyces cerevisiae can involve both binding to the cell wall and the accumulation of copper within the cell. The former process requires the concurrent generation of H2S by the cell via the reduction of sulphate. The contributions of each of these processes to the uptake of 64Cu by wild type and met3-containing (ATP sulphurylase-deficient) strai...

Gelatin-stabilized copper sulphide nanoparticles with conjugated doxorubicin have been developed for combined photoacoustic imaging, enzyme-responsive drug release and photothermal therapy.

An acidophilic, iron-oxidising bacterial consortium was collected from Rio Tinto near Berrocal, Spain. This primary enriched culture was used to examine the effect of acidophilic iron-oxidising bacteria on the stability of soluble gold (I) thiosulphate. Stationary phase cultures and separate components of the cultures (i.e., aqueous ferric iron, iron oxyhydroxide precipitates and non-mineralise...

The low-temperature environment of a free jet expansion provides an excellent laboratory for probing the conformational behaviour of hydrogen bonding. The first observation of axial and equatorial hydrogen-bonded complexes has been reported for tetrahydropyran and pentamethylene sulphide complexes with HCl and HF. Both six-membered rings present two nonequivalent lone pairs at the O or S atoms ...
