The direct reaction of triplet oxygen with a singlet organic molecule would violate a fundamental principle of physics, the conservation of angular momentum, and thus is 'spin-forbidden'.

Triplets and triplet-harvesting materials however have a plethora of applications that extend beyond OLED, such as bioimaging, optical thermometry, singlet oxygen generation or photodynamic therapy.

Before them stood a silvery metal contraption swathed in colourful wires – a box that they hope will one day make oxygen on the moon. Once the team vacated the sphere, the experiment began.

"This reaction should be observed in the upper atmosphere of Mars." Scientists have discovered a new way oxygen can form in carbon-dioxide-rich atmospheres of worlds beyond our own ...

A PaO2 test measures partial pressure of oxygen, or PaO2—the oxygen pressure in arterial blood. The PaO2 reflects how well oxygen is able to move from the lungs to the blood. It is often altered by ...
