Chemical Reactions: A chemical reaction is a process where the substances 8unbdergo a change in their chemical composition. The substances that enter the reaction are called reactants that are then ...

The Diels-Alder reaction is the most iconic organic chemistry reaction. Scientists now report on exactly how this chemical reaction, discovered in 1928, occurs. In 1928, chemists Otto Diels and Kurt ...

This year's Nobel Prize in Chemistry is a little unusual in that it recognizes three things: a conceptual approach to building complicated molecules, a chemical reaction that exemplifies that concept, ...

In the world of chemistry, good things can happen if you just add sugar. A wide range of drugs and biochemical probes — everything from antibiotics to Alzheimer’s disease biomarkers — rely on natural ...

Using an advanced technique, scientists have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface -- what we usually call the water ...

A new technique offers a sharp picture of an elusive and ephemeral stage of a chemical’s life. By precisely measuring the energy of a molecule at the instant it morphs from one form to another, ...

Using a quantum device, researchers have observed, for the first time, a molecular process called conical intersection that is important in reactions such as photosynthesis. When you purchase through ...
