In the present paper, inter-atomic pair potentials in alkali–metals and IB group metals, in crystal state and diatomic system, respectively, are systematically calculated by means of electronic density functional theory with several exchange-correlation (EC) functional approximations. In the absence of experimental potential function information, experimentally available bonding length and bind...

In EU countries approximately 150,000 tons/year of galvanic sludges are generated by 4000 industrial units from the corresponding wastewater treatment plants. These sludges are generally classified as hazardous (European Waste Catalogue as adopted in Council Decision 2000/532/CE and as amended by Decisions 2001/118/EC, 2001/119/EC and 2001/573/CE), basically due to the presence of heavy metals....

Cupriavidus sp. HMR-1 was isolated from a heavy metal-enriched culture of activated sludge from a wastewater treatment plant in Hong Kong. Here, we release the HMR-1 genome to provide basic genetic characteristics for a better understanding of its multiple heavy metal resistance properties.

Characterized by moderate and almost unchanging microbial growth, stability is an essential aspect ofcompost quality Low growth rates give benign organisms a competitive advantage over pathogens such as Sulnronellu and &fhrurn, which thnve m high-growth-rate conditions (Inbar et al., 1990). Also, stability prevents nutrients from becommg tied up in rapid microbial growth, allowing them to be av...

This Communication describes a prototype quantitative paper-based assay that simultaneously measures the levels of Pb(2+) and Hg(2+) in water. The assay requires only measurements of time to yield a quantitative readout, and the results are independent of sample volume, humidity, and sample viscosity.

introduction: heavy metals released from stationaryand mobile origins can be transported in water, air and soil and can be even absorbed by plants, animals and human bodies. trace elements are currently of great environmental concern. nowadays, one of the most important environmental problems is pollution of agricultural soils occurs by heavy metals due to human activities. atmospheric subsiden...
