Abstract:
On a cold, windy night, in a sealed, fire-lit room, the mysterious killer carbon monoxide sneaks into the human body in an attempt to take human life. In a time of crisis, the oxygen army defeats the killer. While celebrating his victory, Brother Oxygen discovers that the body is producing carbon monoxide! Shocked, he wants to find out the reason. After the explanation of the little Brother Carbon Monoxide, he learns that carbon monoxide acts as signaling molecules in the body and is responsible for running errands. He also controls the release of neurotransmitter in brain central, responsible for switching valve work. Finally, the two sides understand each other and turn swords into ploughshares.

Abstract:
When incident light energy is greater than or equal to the forbidden bandwidth of a semiconductor, the electrons in its valence band will be excited to the conduction band, and a reduction reaction will occur. This is the basic principle of the photocatalytic reduction of CO2. In this paper, we introduce the reaction mechanism of the photocatalytic reduction of CO2 into C1 products, and we describe the potential applicability of each product.

Abstract:
In the distant ancient kingdom of bacteria, high temperatures that suddenly came up mercilessly took the lives of bacteria. In the face of disaster, the King of Bacteria was determined to practice the "thermophilic magic skill" to improve the heat resistance of its cell membrane and protein, and led its group to board the "Noah's Ark" to achieve the reproduction. Bacteria not only adapted to high temperature but also fell in love with it, becoming "thermophiles". Through collaboration with human scientists, thermophiles have played an important role in industrial production and other fields, discovering a "new continent" for realizing their own value.

Abstract:
In modern society, with increased consumption, cosmetology, and interest in weight loss, universal fashion trends have gradually developed. More importantly, people are eager to pursue a healthier lifestyle to resist senescence and stay fit. As a result, anthocyanins, the so-called "vitamins of the skin" have emerged in millions of households. They help to eliminate free radicals and have multiple health benefits for the body. This study used an anthropomorphic approach to analyze the structure of anthocyanins, revealing the magical effects of anthocyanins for restoring beauty. We explain the mechanism of action of anthocyanin in antioxidants for weight loss as natural nutritional supplements.

Abstract:
With the Outline of the Action Plan for the Scientific Quality of the Whole People (2021-2035) and the "double reduction" policy, the popular science education of primary and middle school students has gradually received attention of the public. At the same time, the Party and the State also have new requirements for the ideological and political training of young people. In this case, the combination of popular science work and curriculum ideological and political work is a good way of education. In the exploration and practice of the integration of chemical science popularization and curriculum ideology and politics, we try to summarize the "three-stage style" in the ideological and political construction of science popularization. This article will take the popular science exhibition course "a spark starts a prairie fire" as an example, and use the popular science "three-stage style" from the simple to the deep. This paper analyzes and discusses the process of integrating ideological and political education into popular science curriculum for teenagers.

Abstract:
In this popular science experiment, a variety of common green plants were selected for the experiment. The contact angle images were obtained using a mobile phone and microscopic magnifier; the original Python program was used to calculate the contact angle. According to the contact angle phenomenon of different leaves and their surface structure characteristics, glass sheets, Zn sheets, and other materials have been adopted to simulate the microstructure of leaves in a simplified manner. Additionally, bionic surface materials were obtained with different wetting properties. From the application of this blade contact angle phenomenon to the exploration and simulation of surface microstructures, this experiment revealed the relationship between the leaf structure and function from the perspective of interface chemistry and investigated the concept that chemistry comes from life.

Abstract:
The contact angle of liquid on the surface of solid materials is determined by the liquid surface tension, the solid surface tension, and the solid-liquid interface tension, which is an important parameter to measure the wettability of liquid on the surface of material. In this study, the metal mesh, a common material in daily life, is modified from hydrophilic and oleophylic to hydrophilic and oleophobic. The common preparation methods have certain limitations in popular science popularization, therefore, this paper innovatively optimized and improved the preparation scheme. The material prepared by a simple method shows good hydrophilic and oleophobic properties. Thus, this improved experiment has good scientific popularization. In addition, this popular science experiment also designed a variety of popular science exhibitions for different people, so as to improve the public's cognition of chemical knowledge and enhance their environmental awareness.

Abstract:
The experiment is a comprehensive popular science experiment designed on the basis of supramolecular gels preparation, combining the two common principles of flame test and color change of indicator. In the preparation of gel, calcium acetate solution and ethanol were mixed first, metal salt (or boric acid) and acid-base indicator were added. When the gel was ignited, the gel showed colored flame because of the metal salt (or boric acid). The heat leads to hydrolytic equilibrium shift of acetate in the gel, leading to the color change of acid-base indicator in the gel. The exhibition effect of experiment is gorgeous and colorful, just like the bright nebula shining in the universe. The experiment is safe and easy to operate, involving rich knowledge, possessing obvious phenomenon, and showing adequately the beauty of chemistry, which can well meet the learning needs of different groups of people.
