With the fast development of theoretical chemistry methodologies and computer hardware and software technologies, computational chemistry has become more and more imperative in chemical science. Accordingly, we have initiated "Computational Chemistry Experiments" course based on "Introductory Computational Chemistry" course developed in the Department of Chemistry, Tsinghua University since 2013, to provide basic training and computational chemistry practices for undergraduate students. The popular quantum chemistry software Gaussian is used as the major tool in the course. We focus on the exploratory feature of computational chemistry, creating initial structures and optimizing geometries, to provide fundamental training for students to comprehend the difference of traditional experimental chemistry and modern computational chemistry. Systematic research training is offered to develop the creative thinking capacity of students in using computational chemistry methods in chemistry education and research.  相似文献

The present situation of analytical chemistry teaching within a chemistry curriculum is exemplified by the reformed chemistry curriculum in Germany. This approach is contrasted with teaching analytical chemistry within a novel curriculum in natural sciences termed 'applied science'. The latter curriculum ensures a superior education in chemistry, physics, biology, mathematics and information science, thus gaining an integrated perspective of analytical chemistry.  相似文献

As the break out of COVID-19 epidemic, the prevention and control work was consequently carried out. Chemistry plays an important role in the white war. The structure of mask contains the knowledge of interfacial chemistry. The material of mask encompasses the knowledge of polymer chemistry. Nucleic acid test and COVID-19 vaccine research need the knowledge of biological chemistry. The sanitizers involve the knowledge of inorganic and organic chemistry. The knowledge of physical chemistry takes effect in daily hand washing with soap. Each drug against COVID-19 virus was a complex organic compound. All the above things can be taken as appropriate examples in chemistry teaching to display the charm of chemistry. Meanwhile, these examples help students to realize that chemistry works as a vital part in our lives and therefore active their motivation to study chemistry well.  相似文献
