COLUMBIA, S.C. — This experiment is a chemistry experiment that involves a reaction between copper and oxygen, also know as an oxidation reaction. To do this experiment, you will need: pennies a sheet ...

Copper has been essential to human technology since its early days--it was even used to make tools and weapons in ancient times. It is widely used even today, especially in electronic devices that ...

Scientists have discovered that copper foam could provide a new way of converting excess carbon dioxide into useful industrial chemicals. A catalyst made from a foamy form of copper has vastly ...

Researchers have developed a new photocatalytic system that can convert carbon dioxide into carbon monoxide without external electrical input. By studying the role of copper in this system, scientists ...

PROVIDENCE, R.I. -- A catalyst made from a foamy form of copper has vastly different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide, a new ...
