Pusan National University researchers have developed a contactless method for accurately measuring oxygen concentration at high temperature conditions by using the phosphorescence of europium-doped ...

Oxygen plays a key role in various industrial processes, including combustion and energy conversion, which are involved in important fields such as fuel cells, automotive engines, and gas turbines.

Denitrification rates and nitrous oxide (N₂O) effluxes were measured at different temperatures and for different oxygen concentrations in the sediments of a eutrophied river entering the Bothnian Bay.

The ability to non-invasively measure metabolic oxygen flux is a very important tool for physiologists interested in a variety of questions ranging from basic metabolism, growth/development, and ...

Ecologists have long known that agricultural and sewage pollution can cause low oxygen conditions and fish kills in rivers. A new study reports that hippo waste can have a similar effect in Africa's ...
