Spectroscopic and Microscopic Evidence of Biomediated HgS Species Formation from Hg(II)–Cysteine Complexes: Implications for Hg(II) Bioavailability

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Determination of mercury chemical speciation in the presence of low molecular mass thiols and its importance for mercury methylation

Methylmercury (MeHg) is a neurotoxic compound that threatens the well-being of humans and wildlife. It is formed through the methylation of inorganic mercury (HgII) under suboxic/anoxic conditions in soils, sediment and waters. The chemical speciation of HgII, including specific HgII species in aqueous and solid/adsorbed phases, plays a key role in MeHg formation. Chemical forms of HgII which h...

The spectroscopic redshifts of SCUBA galaxies: implications for spheroid formation

We present spectroscopic identifications for a sample of 55 submillimeter(submm)-selected ‘SCUBA’ galaxies, lying at redshifts z = 0.7 to 3.7, that were pinpointed in deep 1.4-GHz VLA radio maps. We describe their properties, especially the presence of active galactic nuclei (AGN) in the sample, and discuss the connection of the SCUBA galaxies and the formation of spheroidal components of galax...
