A ring of beads connected to tentacles A modeling study shows how chemical reactions can stimulate motion in simple systems, like the structure here—made of enzyme coated beads connected to ...
Phys.org: Study reveals why light-driven chemical reactions often lose energy before bond-breaking
Florida State University researchers have discovered a pathway within a certain type of molecule that limits chemical reactions by redirecting light energy. The study could enable development of more ...
Chemistry - Analysis, Reactions, Compounds: Most of the materials that occur on Earth, such as wood, coal, minerals, or air, are mixtures of many different and distinct chemical substances. Each pure chemical substance (e.g., oxygen, iron, or water) has a characteristic set of properties that gives it its chemical identity. Iron, for example, is a common silver-white metal that melts at 1,535 ...
Chemical kinetics, the branch of physical chemistry that is concerned with understanding how fast or how slow chemical reactions occur (that is, their rates). The principles of chemical kinetics apply to purely physical processes as well as to chemical reactions.

CHEMICAL meaning: 1 : 9611; 2 : 2 : a substance (such as an element or compound) that is made by a chemical process
A chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
