Chemist & Materials Scientist
I. JOB SUMMARY
Main Topic: Environment and Society
Secondary Topic: Physical Geography
Overview: Chemists and materials scientists study substances at the atomic and molecular levels and analyze the ways in which the substances interact with one another. They use their knowledge to develop new and improved products and to test the quality of manufactured goods. Some chemists and materials scientists work in basic research. Others work in applied research. In basic research, chemists investigate the properties, composition, and structure of matter. They also experiment with combinations of elements and the ways in which they interact. In applied research, chemists investigate possible new products and ways to improve existing ones. Chemistry research has led to the discovery and development of new and improved drugs, plastics, fertilizers, flavors, batteries, and cleaners, as well as thousands of other products.
Materials scientists study the structures and chemical properties of various materials to develop new products or enhance existing ones. They determine ways to strengthen or combine existing materials, or develop new materials for use in a variety of products. Applications of materials science include inventing or improving ceramics, plastics/polymers, metallic alloys, and superconducting materials. Chemists and materials scientists use computers and a wide variety of sophisticated laboratory instrumentation for modeling, simulation, and experimental analysis. For example, some chemists use three-dimensional computer modeling software to study the structure and properties of complex molecules. If a chemist specializes in green chemistry, he or she will design chemical processes and products that are environmentally sustainable. Green chemistry processes minimize the creation of toxins and waste. Most chemists and materials scientists work as part of a team. The number of scientific research projects that involve multiple disciplines is increasing, and it is common for chemists and materials scientists to work on teams with other scientists, such as biologists, physicists, computer specialists, and engineers.
A growing number of chemists work in interdisciplinary fields, such as biochemistry and geochemistry. Geochemists use physical and organic chemistry to study the composition of elements found in ground water, such as water from wells or aquifers, and of earth materials, such as rocks and sediment.
