The First Homoleptic Complex of Seven-Coordinated Osmium: Synthesis and Crystallographical Evidence of Pentagonal Bipyramidal Polyhedron of Heptacyanoosmate(IV)

Crystals, 2016
The ligand exchange in (n-Bu4N)2OsIVCl6 (n-Bu4N = tetra-n-butylammonium) leads to the formation of the osmium(IV) heptacyanide, the first fully inorganic homoleptic complex of heptacoordinated osmium.

Synthetic Antiferromagnetic Designer Nanodisks for High‐Performance Magnetic Separation

Advanced Healthcare Materials, EarlyView.
Micromagnetic‐modeling‐based design and scalable fabrication of synthetic antiferromagnet (SAF) magnetic disk particles (MDPs) using sputter deposition enable high‐performance magnetic separation. The SAF MDPs achieve high colloidal stability and magnetic responsiveness and enable efficient magnetic separation, outperforming conventional particles ...

DIFFERENTIAL PULSE POLAROGRAPHIC DETERMINATION OF OSMIUM BY CATALYSIS OF PYROGALLOL-RED BROMATE REACTION [PDF]

Journal of Sciences, Islamic Republic of Iran, 1997
A highly sensitive differential pulse polarographic (DPP) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (VIII) on the oxidation of pyrogallol red (PGR) by sodium bromate at pH 7.00 and

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

Advanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

Recovery of valuable metals from industrial wastes

Metalurgija, 2013
Recovery of valuable metals as osmium and rhenium from a industrial wastes are an actual problem. A wastes of copper production treat slime and cake. The content of rhenium in them makes 600 – 2 000 g/t, osmium to 50 g/t.
