Changing the chemistry of a compound is difficult by itself, but modifying materials only a few atoms thick is its own challenge. A group of University of Chicago scientists announced an innovative ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

The film explains the concept of chemical changes, where two or more materials combine to form entirely different substances. It highlights everyday examples of chemical changes, such as burning wood ...

MIT scientists have achieved the first-ever lab synthesis of verticillin A, a complex fungal compound discovered in 1970. Its delicate structure stalled chemists for decades, despite differing from ...

WEST LAFAYETTE, Ind. - A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials ...

The first “atoms” in the universe were not atoms at all—they were just nuclei that had not found electrons yet. The simplest nucleus, that of common hydrogen, is a bare proton with no frills. When the ...
