Pressure impact on the structure, elasticity, and electron density distribution of CaSi2O5
(American Physical Society, 2013-05)
Ab initio molecular dynamics simulations were used to reveal the mechanism of the fivefold to sixfold transition in Si coordination numbers of CaSi2O5. The longest first-neighbor Si-O distance drops from 2.8 to 1.8 angstrom ...
Low Concentrations of Silver Nanoparticles in Biosolids Cause Adverse Ecosystem Responses under Realistic Field Scenario
A large fraction of engineered nanomaterials in consumer and commercial products will reach natural ecosystems. To date, research on the biological impacts of environmental nanomaterial exposures has largely focused on ...
