Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

A clear and easy breakdown of butane, its physical properties, and how it reacts in everyday situations. Perfect for understanding the science behind common fuels and chemical reactions. #Chemistry ...

A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and ...

The electrodes are coated with carbon nanotubes. As they flow through the reactor, the reactants interact weakly with the carbon nanotubes, exposing them to the electric field. This induces electronic ...

Researchers have observed steric effects—the interactions of molecules depending on their spatial orientation (not just between their electrons involved in bonding)—in a chemical reaction involving ...

Calcium carbonate is a chemical found in eggshells, seashells, and many other materials. Observe how calcium carbonate reacts with common liquids. A Plaster Master or a Plaster Disaster Plaster is ...
