The transition from fossil fuels to renewable energy sources strongly depends on an availability of effective systems for energy conversion and storage. Considering hydrogen as a carrier molecule, …
Guinea’s best hope for coronavirus patients lies inside a neglected yellow shed on the grounds of its main hospital: an oxygen plant that has never been turned on. The plant was part of a hospital …
At least half of the oxygen produced on Earth comes from the ocean, mostly from tiny photosynthesizing plankton. But marine life also uses roughly the same amount of oxygen to breathe, for cellular …
The summertime low-oxygen “dead zone” in the Gulf of Mexico is expected to cover at least 6,700 square miles along the Louisiana and eastern Texas coasts at the end of …
Why do carbon dioxide levels in the atmosphere wax and wane in conjunction with the warm and cold periods of Earth’s past? Scientists have been trying to answer this question for many years, and …
Amongst existing technologies, hydrogen evolution by photocatalytic dissociation of ubiquitous water in a photoelectrochemical cell (PEC) is one of the simple processes to convert solar energy into a …
During the past two decades, scientists have learned how hypoxia and acidification can act and interact to harm marine organisms. Hundreds of low oxygen or dead zones have been identified across the …
Stanford University, California experts believe that the ‘Late Ordovician’ mass extinction 450 million years ago was due to widespread ‘anoxia’, or oxygen depletion, over a three million year period.
Coronavirus concerns have led to a run on grocery stores and short supply of protective gloves and masks. But folks with respiratory conditions who need oxygen may have a new concern: Not enough …
Oxygen isotope values of lunar samples correlate with lithology, and we propose that the differences can be explained by mixing between isotopically light vapour, generated by the impact, and the …
