Digital education plays a crucial role in promoting high-quality educational development,making the construction and application of digital resources particularly important.In the context of digital empowerment,this paper focuses on the construction of digital teaching resources for inorganic and analytical chemistry experimental course.Three aspects are discussed:the creation of a teaching video resource library,the development of a bilingual virtual simulation experiment,and the introduction of high-quality shared resources.These resources are then applied in teaching practice to enrich digital teaching materials,enhance online teaching platforms,and reform blended teaching models.Ultimately,this approach enhances the flexibility of experimental teaching,promotes diverse teaching methods,and improves the effectiveness of teaching.

Electrocatalysis,as a focal point in the fields of nanomaterials and energy chemistry,holds the key to futural energy storage and conversion technologies. Against the backdrop of "carbon peak" and "carbon neutrality",electrocatalytic nitrate reduction into ammonia is recognized as a green and safe technique. In order to bridge the gap between cutting-edge research and experimental teaching,we have developed a comprehensive chemical experiment centered on electrocatalytic nitrate reduction into ammonia. With an integrated design of basic knowledge,scientific studies and practical applications,this experiment contains hierarchal contents of copper-based catalysts,including its synthesis and characterization,performance exploration and applicable design. This experiment is designed to help undergraduate students gain insights into the latest advancements in electrocatalysis,master its fundamental knowledge and research methods,and foster their innovation awareness and practical application abilities.

中华文化如浩渺星空,群星闪耀,诗词与成语作为星空中的璀璨明珠不仅蕴含着丰富的人文内涵,亦闪耀着夺目的理性光辉。本文将跟随科普家族成员大华和小雪的脚步一同走进原始部落,边游历边探寻诗词与成语中的化学韵味,领略中华文化的博大精深。

This is a popular science article introducing the chemical knowledge contained in the search and use of colors. From the different aspects of architectural, textile dyeing and paints, three examples are chosen to reveal the chemical principles behind. Humanistic story and science interpretations are combined to reflect the close connection between chemistry and human life.

This paper mainly introduces the role of isotopes in exploring the origin of life and related principles. In addition, by reviewing the discovery history of isotopes and summarizing the contributions of major scientists, we hope to show the general process of science developments to the public.

随着手机等移动终端的信息获取越来越便利,新媒体已逐渐成为人们获取信息的主要途径.微信公众平台已经成为人们日常生活中接收信息的主要渠道之一.本文介绍了利用微信公众平台"化学科普园地"开展科普工作的一些实践,以及在此过程中遇到的一些困难与思考.

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.
