By putting a carbon atom in place of a core oxygen, chemists constructed an opioid that blocks pain with less respiratory ...

A study shows that low-temperature oxidation impacts lignite's microstructure, increasing spontaneous ignition risk by ...

Counterintuitively, the researchers also found something surprising: long-range effects from aromatic rings far away from a catalyst site can sometimes cause the alcohol groups of the carbon to become ...

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the ...

MXenes are typically inert because their surfaces are covered with protective functional groups—oxygen, hydrogen and fluorine atoms that remain after acid exfoliation.

They were randomly assigned to a target functional oxygen-saturation range of either 91 to 94 percent (standard-saturation group) or 95 to 98 percent (high-saturation group); this target was ...

States have also been urged to ensure the availability of functional life support equipment such as ventilators, BiPAP and SpO2 systems along with their consumables.
