Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

Researchers have quantified a pathway for the formation of molecular oxygen from the interaction of carbon dioxide with electrons, key information for searches of life on other worlds. Molecular ...

Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and ...

A "hidden variable" that can determine the success or failure of a chemical reaction has been found in the immediate vicinity ...

Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring molecule to measure the oxygen level in cells. The tool could provide a simple ...

Chemists have long assumed that if they get the voltage right, choose the right electrode material, and tune the composition of their electrolyte solution, an electrochemical reaction will behave ...
