Index Everything in the environment, whether naturally occurring or of human design, is composed of chemicals.
Chemists search for and put to use new knowledge about chemicals.
Chemical research has led to the discovery and development of new and improved synthetic fibers, paints, adhesives, drugs, cosmetics, electronic components, lubricants, and thousands of other products. Chemists also develop processes that save energy and reduce pollution, such as improved oil refining and petrochemical processing methods. Research on the chemistry of living things spurs advances in medicine, agriculture, food processing, and other fields. Chemists apply their knowledge of chemistry in various ways. In basic research, chemists investigate properties, composition, and structure of matter and the laws that govern the combination of elements and reactions of substances.
