6 g/cm3 have lower equivalent circulation density(ECD) if manganese tetraoxide is used as the weighting agent,instead of barite.

Subsequently, the carbon double bonds involved in the copolyester main chain were subjected to dihydroxylation with catalyst of osmium tetroxide (OsO 4), N-methylmorpholine N-oxide (NMO) and water to prepare novel biodegradable copolyesters bearing hydrophilic hydroxyl pendant groups.

Here we introduced the successful application of catalytic amount of osmium tetroxide in the oxidation of alkenes with good stereoselectivity.
