Giant magnetic anisotropy at the nanoscale: Overcoming the superparamagnetic limit
(American Physical Society, 2006)
It has been observed for palladium and gold nanoparticles that the magnetic moment at a constant applied field does not change with temperature over the range comprised between 5 and 300 K. These samples, with sizes smaller ...

Reduction of N2O with hydrosilanes catalysed by RuSNS nanoparticles
(Royal Society of Chemistry, 2022)
A series of RuSNS nanoparticles, prepared by decomposition of Ru(COD)(COT) with H2 in the presence of an SNS ligand, have been found to catalyse the reduction of the greenhouse gas N2O to N2 employing different hydrosilanes.
