Word to Youngsters Welcome to the newly established high school student section! For students to have a deeper understanding of chemical engineering and the research fields of the department, we will be answering the questions in Q&A form concerning the general misconceptions. In addition, the research conducted by the teachers and students of the department is presented in the web graph form basing on the five advanced fields, we wish to increase the students' understanding of the Department of Chemical Engineering in the shortest possible time. The Department of Chemical Engineering of National Taiwan University is the department with the longest history, it has the most complete and advanced research field in the country. Inheriting the tradition from the past, it is our mission to pursue academic excellence, social contribution, and innovation. We were rated as one of the top ten outstanding departments in National Taiwan University. Regardless of the basic engineering knowledge, we have made outstanding achievements in various fields such as optoelectronic materials, biotechnology, energy and environment, green chemical technology, nanometer and interface technology. Our graduates are widely distributed in the semiconductor, optoelectronic materials, and biomedical technology industries, making enormous contributions. Therefore, we hope that the information presented here can attract more students who are interested in chemical engineering, so that we can learn and progress together, and one day become a part of national construction.
