Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. A catalyst is a substance that speeds up a chemical reaction.

A new theory predicts one of the effects of macroscopic mechanical forces on mechanochemical organic synthesis by a ball mill.

Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its change, for instance through chemical reactions. Supported noble metal ...

The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration shown in this video is very dangerous. Do not attempt to perform ...

We report a procedure for achieving that goal in our paper." The team has designed a procedure and software package for visualising chemical reactions involving small molecules. It’s based on a ...

Enzymes are crucial to life. They are nature's little catalysts. In the gut, they help us digest food. They can enhance ...

A new ML-guided platform can design thousands of new enzymes, predict how they will behave in the real world, and test their ...

Chemical biology is the study of the chemicals and chemical reactions involved in biological processes, incorporating the disciplines of bioorganic chemistry, biochemistry, cell biology and ...
