Osmium Recovery as Membrane Nanomaterials through 10–Undecenoic Acid Reduction Method
Membranes, 2021 The recovery of osmium from residual osmium tetroxide (OsO4) is a necessity imposed by its high toxicity, but also by the technical-economic value of metallic osmium.

2D and 3D immunogold localization on (epoxy) ultrathin sections with and without osmium tetroxide
Microscopy research and technique (Print), 2020 For nearly 50 years immunogold labeling on ultrathin sections has been successfully used for protein localization in laboratories worldwide. In theory and in practice, this method has undergone continual improvement over time. In this study, we carefully

Toxic Manifestations of Osmium Tetroxide [PDF]
Occupational and Environmental Medicine, 1946 Osmium is one of the precious metals and was discovered in 1803 by Tenant. It occurs naturally in close association with iridium. Osmiridium is an exceptionally hard alloy with a high melting point (2700? C.) and for this reason it is used extensively for tipping fountain-pen nibs.
