Singlet oxygen (¹O₂) occupies a central role in photodynamic therapy (PDT) through its capacity to oxidise biological targets selectively upon activation of a photosensitiser by light. Generated via ...

The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several ...

NASA's Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated ...

In space, bubble trouble hampers oxygen production needed for astronauts to breathe. But neodymium magnets could coax bubbles off electrodes in microgravity to boost the efficiency of splitting water ...

For the first time, researchers have managed to isolate and directly observe individual oxygen atoms inside liquid water, catching a substance that usually hides behind the familiar H 2 O formula in ...

A new race to the moon is emerging between the United States and China. Unlike fifty years ago, the goal is no longer just ...

That would have enabled more of this organic carbon—and carbonate accumulating in shallow water around Columbia—to be subducted deep into the mantle. Then comes the Boring Billion, when even mantle ...
