At TU Wien (Vienna), it has become possible to control one of the most important chemical processes: switching oxygen molecules between a reactive and unreactive state. Oxygen atoms are highly ...

Scientists have studied the vibration of four gases using electron microscopy and spectroscopy. Combined with simulations, they measured the increased vibration at 1,000°C compared with room ...

The ability to query enzyme molecules individually is transforming our view of catalytic mechanisms. Quiescin sulfhydryl oxidase (QSOX) is a multidomain catalyst of disulfide-bond formation that ...

Reactive molecular oxygen singlets have a multitude of uses in chemistry and medicine, but they are less abundant than non-reactive oxygen triplets. A multinational research team has developed a novel ...

Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early atmosphere ...

In this study, chiral gold nanoparticles with a concave vortex cube structure were employed as the chiral substrate, exhibiting highly tunable optical chirality and intriguing chiral-induced spin ...
