Chemical engineering: an engineering discipline that studies the laws of chemical and physical processes in chemical industry and other process industries. These industries include not only traditional chemical manufacturing (such as petroleum refining, metal materials, plastic synthesis, food processing and catalytic manufacturing). ), including modern chemical engineering, biopharmaceuticals and related nanotechnology.

Material science: Material science is a science that studies the organizational structure, performance, production process, utilization efficiency and their relationship of materials, and integrates physics, chemistry and metallurgy. Material science is an applied science which is inseparable from engineering technology.
