Abstract:
Although their contents in the human body are extremely low, even less than 0.01 wt%, trace elements are essential for the human body. As a kind of trace element, zinc plays an important role in human growth and development, reproductive inheritance, immunity, endocrine and other important physiological processes. At the same time, zinc deficiency is also a common phenomenon among Chinese children. Through the fictional experience of the fictional Zinc Gu Cheng, this article uses the anthropomorphic approach to popularize the role of zinc. Finally, the story ends with a little girl's dream. We hope that through this short story, people can understand the importance of zinc to the human body and realize the indispensable role of trace elements.

Abstract:
Using the anthropomorphic approach, this article introduces the discovery history of ruthenium elements in the first person role, and focuses on the ruthenium complexes as important therapeutic agents for cancer treatment. We have focused our attention on KP1019 incorporating ruthenium ions complexes which have been already used in clinical or have been advanced to clinical trials as anticancer agents. Moreover, the half-sandwich ruthenium and ruthenium polypyridine complexes drugs are also reviewed.

Abstract:
Starting from an example of how to extinguish a fire, this article illustrates how chemical dynamics plays a role in our life. It also introduces what is chemical dynamics and the contribution of Dutch chemist Jacobus H. van't Hoff to chemical dynamics. The horse racing analogy is used to illustrate how the amount of reactants, energy, catalysts and other factors affect the chemical reaction rate.

Abstract:
This paper reviews the course of understanding vitamin C. From the "sea god" that sailors first encountered to the scurvy that caused the British Navy to suffer, understanding vitamin C is improved little by little. Until modern times, with the guidance of advanced theory and the rapid development of chemical research, human beings finally got to known vitamin C and conquered scurvy. This marks the arrival of a new era.

Abstract:
Amid five tastes, only salt is indispensable. As a kind of essential nutrition, salt plays a vital role in our daily life. Although the salt is in small particle size, yet it received a lot of rumors. In recent years, rumors on salt have sprung like mushrooms including sea salt, iodized salt, low sodium salt, additive in salt and so on. To stop the rumors from spreading and to clarify that the salt is innocent, a debate competition was applied to tell the truth:rumors are guilty rather than salt!

Abstract:
Through three stories about nitrates, a storytelling technique is used to describe the main uses of nitrates today, including agricultural fertilizers, industrial explosives, and food preservatives. Nowadays, nitrate is suspected to be the main cause of carcinogenesis, but one coin has two sides; in fact, nitrates play an important role both in the ecological environment and in the human body. Therefore, the public can understand more about the applications of nitrates from this article. Through the accidental discovery of a rural couple in a wartime setting, this article describes the uses of nitrate in agriculture, antiseptic, immune systems and blood circulation system.
