Chemistry is a study that identifies the structure and properties of substances and creates new substances with new functions. It consists of the following fields: Materials science fields such as the development of new drugs and materials; Environmental fields such as the manufacture of environment-friendly substances or detection and treatment of environmentally hazardous substances; Energy fields such as solar cells and fuel cells NT field, which develops devices with new functions through molecular regulation, etc. Chemistry is an essential academic field in most fields such as engineering, agriculture, and medicine. Therefore, this major provides a foundation for advancing into various applied science fields through new understanding of chemistry and creative application process, including the foundation for scientific thinking as well as application skills by linking experiments and theories.
