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 ...

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 ...

Oxygen atoms are highly reactive, yet the world does not spontaneously burn, even though everything is surrounded by this aggressive element. Why? The reason is that normal O2 molecules, are not ...

image: Enzyme-Photo-coupled Catalytic System (EPCS) is an emerging platform technology for green biomanufacturing that uses photocatalysts to capture solar energy and subsequently drives the enzyme ...

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 ...

A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study, published in ...

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 ...

We humans need oxygen to breath - for a lot of microbes it is a lethal poison. That is why microorganisms have developed ways to render oxygen molecules harmless. Microbiologists have now succeeded in ...
