The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

This essay assessed the chemical safety knowledge of students in the School of Chemistry and Chemical Engineering, Tianjin University of Technology, concerning chemical storage, heat operation, waste disposal, and emergency response. The results show that students' familiarity and understanding of safety knowledge is not satisfactory, especially…

A research-style laboratory experiment composed of the synthesis of MOF-74 materials, related structural characterization, and the cutting-edge application of electrocatalytic oxygen evolution reaction (OER) has been designed toward advanced undergraduates at East China University of Technology (ECUT). The desired monometallic MOF-74 (Ni-MOF-74…

Given the big gap between rural areas and cities and developed areas of China in basic education, it is of great significance to train a large number of excellent teachers for basic education in the vast rural areas so as to boost basic education there and achieve educational equity. Hanshan Normal University is a regional normal university…

This work investigates students' familiarity and understanding of laboratory safety knowledge among students in the College of Environmental Science and Safety Engineering at Tianjin University of Technology. A total of 1301 undergraduates and graduates participated in a survey of students' safety knowledge. The questionnaire covered the GHS…

The Coronavirus disease 2019 (COVID-19) pandemic in China has changed higher education dramatically, with a distinctive rise in online instruction. Here, we describe the major successes and challenges encountered during the full implementation of online chemistry instruction in higher education in China based on questionnaires answered by 56…

In response to China's Ministry of Education's directive for "postponement of school without suspension of learning" to combat the spread of COVID-19, we commenced online classes at Shandong University. Teaching in an online environment presented a number of challenges in comparison with face-to-face instruction. A key question raised…

The practice and research on online chemistry education have received great attention in the context of the COVID-19 pandemic worldwide. This paper describes the teaching practice of online learning based on three online courses for pre-service chemistry teachers. To adapt online teaching requirements, we reshaped the structure of the physical…

Relying on the National-Local Joint Engineering Laboratory and National Chemical Design Competition for college students, a multidimensional education mode presented here combines the advantages of problem-based learning (PBL) and "Conceive-Design-Implement-Operate" (CDIO) approaches, while also overcoming the restrictions of PBL and…

A demonstration is described of electrophoretic separation of carmine and sunset yellow with a paper-based device. The channel in the paper device was fabricated by hand with a wax pen. Electrophoretic separation of carmine and sunset yellow was achieved within a few minutes by applying potential on the channel using a simple and inexpensive power…

The reaction process of copper-aluminum displacement in agar gel was observed at the microscopic level with a stereomicroscope; pine-like branches of copper crystals growing from aluminum surface into gel at a constant rate were observed. Students were asked to make hypotheses on the pattern formation and design new research approaches to prove…

Scanning electron microscopy (SEM) was introduced into undergraduate physical chemistry laboratory curriculum to help students observe the phase composition and morphology characteristics of tin-lead alloys and thus further their understanding of binary alloy phase diagrams. The students were captivated by this visual analysis method, which…

Practical education in chemical engineering has drawn increasing attention in recent years. This paper discusses two approaches to teaching and learning about experiments among upper-level chemical and pharmaceutical engineering majors in China. On the basis of years of experience in teaching chemical and pharmaceutical engineering, we propose the…

As worldwide energy shortages and environmental degradation increase, along with steady increases in population, current science and technology are confronted with many challenges to successfully sustain our society. Among the existing promising choices, photocatalysis has been widely considered as a potential solution to energy and environment…

An HPLC undergraduate experiment on the analysis of traditional Chinese medicine (TCM) has been developed. Two commonly used herbs ("glycyrrhizae radix" and "cinnamomi ramulus") are studied. Glycyrrhizin, cinnamic acid, and cinnamaldehyde are chosen as markers for the herbs. The dried herbs in their natural state and a TCM…
