Carbon monoxide adsorption on platinum-osmium and platinum-ruthenium-osmium mixed nanoparticles
Journal of Chemical Physics, 2013 Density functional calculations (DFT) on carbon monoxide (CO) adsorbed on platinum, platinum-osmium, and platinum-ruthenium-osmium nanoclusters are used to elucidate changes on the adsorbate internal bond and the carbon-metal bond, as platinum is alloyed with osmium and ruthenium atoms.

Osmium and OsOx nanoparticles: an overview of syntheses and applications [PDF]
Open Research Europe, 2022 Precious metal nanoparticles are key for a range of applications ranging from catalysis and sensing to medicine. While gold (Au), silver (Ag), platinum (Pt), palladium (Pd) or ruthenium (Ru) nanoparticles have been widely studied, other precious metals are less investigated. Osmium (Os) is one of the least studied of the precious metals.

Effects of nanomaterials on Cs3Sb photocathode emission performance
AIP Advances, 2022 A new approach to preparing the cesium antimonide photocathode has been developed. A tungsten sponge diffusion barrier layer, instead of the conventional nickel pipe, was used as the evaporation source so that a slow and uniform evaporation of the ...

Synthesis and controlled growth of osmium nanoparticles by electron irradiation [PDF]
Dalton Transactions, 2015 Defined-size osmium nanoparticles (1.5–50 nm) were synthesized on a B- and S-doped turbostratic graphitic structure from an organometallic osmium complex encapsulated in self-spreading polymer micelles and characterised by (HR)TEM, AFM and XPS.

Tripodal Osmium Polypyridyl Complexes for Self-Assembly on Platinum Nanoparticles [PDF]
The Journal of Physical Chemistry Letters, 2011 The combination of platinum nanoparticles with a tripodal osmium complex that anchors to the metal surface leads, under visible light irradiation, to the formation of solvated electrons. The formation kinetics is limited by the detachment of the electron from the platinum surface into the solution, the particle showing a type of capacitor behavior.
