Not exact matches

By looking at the chemistry of rocks deposited during that time period, specifically coupled carbon and sulfur isotope data, a research team led by University of California, Riverside biogeochemists reports that oxygen - free and hydrogen sulfide - rich waters extended across roughly five percent of the global ocean during this major climatic perturbation — far more than the modern ocean's 0.1 percent but much less than previous estimates for this event.

When an oxygen molecule comes in and wants to react with that surface, much less energy is needed to break the oxygen - oxygen bond in the oxygen molecule.

A future hydrogen economy could use the gas as an energy carrier As this method doesn't produce oxygen which needs to be kept separate from hydrogen, safety from explosion of the two gases is much less of a problem with electricity in the national grids carried by ageing cables, it would be useful to replace them by passing the hydrogen along gas pipes used currently for natural methane gas.
