Chemists search for and put to practical use new knowledge about substances.
Their research has resulted in the development of a tremendous variety of new and improved synthetic fibers, paints, adhesives, drugs, electronic components, lubricants, and other products. They also develop processes which help save energy and reduce pollution, such as improved oil refining methods. Research on the chemistry of living things provides the basis for advances in medicine, agriculture, and other areas. Most chemists work in research and development. In basic research, chemists investigate the properties, composition, and structure of matter and the laws that govern the combination of elements and reactions of substances.
