Abstract:
Following the discovery and application of 1,4-dihydropyridines nimodipine as the antihypertensive drug, this article briefly reviews the development of stereochemistry in Europe since the middle of the 19th century. Chemical stories are introduced, involving the invention of Hantzsch esters, close relationship between Hantzsch and his outstanding student-the founder of Coordination Chemistry-Werner, and Werner's pioneering contribution to chiral stereochemistry. An up-to-date introduction is given for the spontaneous resolution of racemic nimodipine under chiral crystallization and its precise characterization. Moreover, polymorphism and polymorphic drugs have been also described.

Abstract:
The history, chemical properties, preparation methods, metabolic pathways and physiological functions of caffeine are introduced in a fantastic way. The working mechanism of caffeine in the human body is compiled in an interesting fairy tale. In this story, a boy fought against caffeine goddess and made her angry. She seduced the boy to extract and sell caffeine as drugs. But by the time of the deal, the goddess was softened by his apology and stopped the vengeance. However, the fact is that the teenager sold the caffeine as medicine rather than narcotics. The vengeance plan of the goddess had not been successfully implemented and the story had a happy ending.

Abstract:
This is a virtual scientific fiction story. It mainly tells the story of a fictional character, Professor K, who finds staphylococcus alpha hemolysin that can be used as a nanopore in coincidence. When Professor K was thinking about the method of gene sequencing, he was inspired by the dream of Staphylococcus aureus attacking red blood cells. Finally, he got the method of nanopore sequencing from the dream.

Abstract:
Ever since nitroglycerin had been synthesized from 1846, people had always used it as explosives. However, because nitroglycerin is so sensitive that even a small touch can cause an accident. Nobel successfully reduced the sensitivity of nitroglycerin by mixing Nitroglycerin with diatomite. Later on, people found that Nitroglycerin can relieve angina, thus, in-depth studies were carried out. This article will show the public aforementioned functions of nitroglycerin.

Abstract:
Capsaicin is the main metabolite of capsicum, which is closely related to people's diet. Proper intake of capsaicin not only brings spicy sensation to people, but also plays a certain role in slowing down fatigue, lowering blood sugar, and fat, protecting stomach and intestines, relieving pain, resisting radiation and treating cancer. Although an appropriate amount of capsaicin can benefit the human body, the excessive intake of capsaicin is still harmful. This article explains the action and various applications of capsaicin, and emphasizes that the rational use of capsicum is aimed at its role.

Abstract:
Based on the laboratory teaching resources in the School of Chemistry and Molecular Engineering, East China Normal University, an open-to-public chemical science base has been constructed for the teenagers. With visual effects that embody different themes and experimental contents on hardware, this popular science base can be used for both chemistry laboratory teaching, as well as science and technology demonstration. Some special chemistry practice courses have been set up, and a series of interesting chemistry experiments and chemical inquiry projects have been designed, which facilitate chemical practice and chemical research for a variety of people in the public. Custom-designed for primary and high school students and teachers, and the students in the normal university, a "three-in-one" teaching practice mode has been established, which effectively solve the contradiction between the functions of service society and the education training objectives in the university. The construction of the popular science base of East China Normal University has made exploration and practice beneficial to stimulating teenagers' interest in science, training exploration and innovation ability in chemistry experiment, and realizing the social service function of universities.

Abstract:
The National Demonstration Center for Experimental Chemistry Education of Peking University has been committing to explore and practice the effective way of science popularization. Through the construction of the science popularization base, completing several science popularization projects and taking part in many times of science popularization activities, we gradually accumulated some effective work modes on how to carry out the science popularization work in universities. This paper shows the relationship between life and chemistry, discusses the construction of base and the development of product, and demonstrates the content and form of science popularization. We expect colleges, universities and research institutes could play their leading role in the work of science popularization.

Abstract:
In this paper, a simple version of UV-Vis spectrometer was constructed to illustrate structure of the spectrometer and the function of the equipment components. Modern UV-Vis spectrometer tends to be present as "black box" that the inner construct is not visible, however, the open UV-Vis spectrometer can solve this problem. Interesting interactive experiments were conducted with this equipment. The inner connections between color, pigment density and optical spectrum were clearly illustrated by measuring colored drinks using the UV-Vis spectrometer. Furthermore, knowledge of chemistry and instrument was well introduced to people of different ages.
