Although the SARS-CoV-2 vaccine has largely controlled the spread of the virus, the scientific and sustainable treatment of COVID-19 patients is still necessary to truly end the pandemic. Small-molecule drugs against COVID-19 have attracted the attention of the scientific community and industry owing to their unique advantages such as a simple delivery method, relatively high output, and immune response with lower probability. Fortunately, in the last three years, some potentially effective drugs have been proposed, and have achieved good results in clinical trials.

It has the characteristics of strong acidity and high concentration of fluoride and metal ions. In this experiment, graphene simulated wastewater were treated by four methods, including single coagulation, neutralization coagulation, coagulation flocculation, and neutralization coagulation and flocculation. These methods were compared to remove contaminants such as fluoride and metal ions. The ion content and sediment in the wastewater were analyzed using ion chromatography and X-ray powder diffraction. The results show that the combination of sodium hydroxide, calcium hydroxide, and flocculant has the best fluoride removal effect. The removal rates of fluoride and metal ions reached 98% and 99.5%, respectively. Compared with the traditional process, the sediment is reduced by over 50%. The experiment was easily operated and observed. The experimental content highlights that combining practice and theory methods enriches the teaching design of experimental courses and guides students to understand the current situation of industrial production, improve their awareness of environmental protection, and master the usage of chemical software and ability of data analysis and processing.

In these experiments, students complete only the operation practice of \"prescription preparation\", and their practical ability of constructing an HPLC analysis scheme for specific objects is ineffectively cultivated. Therefore, we propose an improved procedure:the chromatographic injection practice and determination of rhubarb anthraquinone compounds are organically combined, and the chromatographic conditions are optimized using the virtual simulation software HPLC Simulator without prolonging the class time. Retention data under different temperature and mobile phase compositions were obtained in the injection practice experiment, and the data were shared by all students. The green optimization of the chromatographic conditions was then realized using HPLC Simulator. The optimal chromatographic conditions simulated were verified in a second experiment. This improved experiment transfers the boring chromatographic injection practice into an exploratory experiment that stimulates students' learning enthusiasm. It can help students master the green optimization of chromatographic conditions in limited class hours, cultivate their ability to solve practical problems using information technology, and improve the experimental teaching quality under the informatization background. In addition, the sharing of experimental data may cultivate students' teamwork spirit.","articleNo":"20230819","authorCnList":["石志红"," 边刚"," 张红医"," 张博然"],"authorEnList":["Zhihong Shi"," Gang Bian"," Hongyi Zhang"," Boran Zhang"],"authorList":["石志红"," 边刚"," 张红医"," 张博然"],"authors":"石志红, 边刚, 张红医, 张博然","authorsCn":"石志红, 边刚, 张红医, 张博然","authorsEn":"Zhihong Shi, Gang Bian, Hongyi Zhang, Boran Zhang","categoryName":"化学实验","categoryNameCn":"化学实验","categoryNameEn":"Chemistry Laboratory","citation":"石志红, 边刚, 张红医, 张博然. 虚拟仿真软件辅助液相色谱分离条件的绿色优化实验. 大学化学, 2023, 38(8): 136-144. doi: 10.3866/PKU.DXHX202208074.","citationCn":"石志红, 边刚, 张红医, 张博然. 虚拟仿真软件辅助液相色谱分离条件的绿色优化实验. 大学化学, 2023, 38(8): 136-144. doi: 10.3866/PKU.DXHX202208074.","citationEn":"石志红, 边刚, 张红医, 张博然.

Although most of the experimental projects in existing textbooks focus on the qualitative and quantitative analysis of compounds, which are mainly based on infrared spectroscopy, there are few experimental investigations on infrared spectroscopy involving intermolecular hydrogen bonding and quantum chemical calculations. In this study, based on original infrared spectroscopy experiments, several common aliphatic alcohols were used as examples to investigate the infrared spectral characteristics of alcohol-carbon tetrachloride solutions with different percentages (V<\/i>/V<\/i>%). The hydrogen bond structures were explored in combination with quantum chemical calculations. The improved teaching method, combining macro and micro that is experimental phenomena and molecular structure respectively, may enable students to have a clearer understanding of the original frequency values of absorption peaks and the microscopic effect of intermolecular hydrogen bonds. In addition, it can significantly improve their interest in learning, broaden their horizons, and cultivate innovative thinking and critical thinking skills.","articleNo":"20230829","authorCnList":["刘禹"," 郑纪鸣"," 宗陈纳言"," 吴红"," 胡万群"],"authorEnList":["Yu Liu"," Jiming Zheng"," Nayan Zongchen"," Hong Wu"," Wanqun Hu"],"authorList":["刘禹"," 郑纪鸣"," 宗陈纳言"," 吴红"," 胡万群"],"authors":"刘禹, 郑纪鸣, 宗陈纳言, 吴红, 胡万群","authorsCn":"刘禹, 郑纪鸣, 宗陈纳言, 吴红, 胡万群","authorsEn":"Yu Liu, Jiming Zheng, Nayan Zongchen, Hong Wu, Wanqun Hu","categoryName":"化学实验","categoryNameCn":"化学实验","categoryNameEn":"Chemistry Laboratory","citation":"刘禹, 郑纪鸣, 宗陈纳言, 吴红, 胡万群. 几种常见脂肪醇的氢键结构探究——红外光谱测定结合量化计算的实验. 大学化学, 2023, 38(8): 216-224. doi: 10.3866/PKU.DXHX202210029.","citationCn":"刘禹, 郑纪鸣, 宗陈纳言, 吴红, 胡万群. 几种常见脂肪醇的氢键结构探究——红外光谱测定结合量化计算的实验. 大学化学, 2023, 38(8): 216-224. doi: 10.3866/PKU.DXHX202210029.","citationEn":"刘禹, 郑纪鸣, 宗陈纳言, 吴红, 胡万群.

However, in experimental teaching, there have always been problems, such as the use of toxic or controlled reagents, long experiment time, cumbersome experimental steps, and poor experimental results. In this study, the conditions of thin layer chromatography were systematically explored. A variety of reagent combinations, such as n<\/i>-hexane/anhydrous ethanol and n<\/i>-hexane/n-butanol, were tested. It was found that the developing agent with the best separation effect was n<\/i>-hexane/anhydrous ethanol solution, with a volume ratio of 10:1. The n<\/i>-hexane/absolute ethanol and n<\/i>-hexane/n<\/i>-butanol were also used as eluents to explore column chromatography separation experiments of the pigments from spinach leaf. By using silica gel as the stationary phase, the optimal gradient elution scheme with n<\/i>-hexane/absolute ethanol as eluent was obtained; whereas, the optimal gradient elution scheme with n<\/i>-hexane/n<\/i>-butanol as the eluent was obtained by using neutral alumina as the stationary phase. Following the improvement, the separation effect was enhanced and the amount of reagent was reduced; furthermore, more friendly reagents were used and the teaching time was shortened.","articleNo":"20230834","authorCnList":["黄婷婷"," 王若楠"," 高展"," 孙继超"," 马莹"," 张恒"," 贾春江"," 徐政虎"," 苑世领"," 刘刚"],"authorEnList":["Tingting Huang"," Ruonan Wang"," Zhan Gao"," Jichao Sun"," Ying Ma"," Heng Zhang"," Chunjiang Jia"," Zhenghu Xu"," Shiling Yuan"," Gang Liu"],"authorList":["黄婷婷"," 王若楠"," 高展"," 孙继超"," 马莹"," 张恒"," 贾春江"," 徐政虎"," 苑世领"," 刘刚"],"authors":"黄婷婷, 王若楠, 高展, 孙继超, 马莹, 张恒, 贾春江, 徐政虎, 苑世领, 刘刚","authorsCn":"黄婷婷, 王若楠, 高展, 孙继超, 马莹, 张恒, 贾春江, 徐政虎, 苑世领, 刘刚","authorsEn":"Tingting Huang, Ruonan Wang, Zhan Gao, Jichao Sun, Ying Ma, Heng Zhang, Chunjiang Jia, Zhenghu Xu, Shiling Yuan, Gang Liu","categoryName":"化学实验","categoryNameCn":"化学实验","categoryNameEn":"Chemistry Laboratory","citation":"黄婷婷, 王若楠, 高展, 孙继超, 马莹, 张恒, 贾春江, 徐政虎, 苑世领, 刘刚. “菠菜叶中色素的提取与分离”实验改进. 大学化学, 2023, 38(8): 259-267. doi: 10.3866/PKU.DXHX202210003.","citationCn":"黄婷婷, 王若楠, 高展, 孙继超, 马莹, 张恒, 贾春江, 徐政虎, 苑世领, 刘刚. “菠菜叶中色素的提取与分离”实验改进. 大学化学, 2023, 38(8): 259-267. doi: 10.3866/PKU.DXHX202210003.","citationEn":"黄婷婷, 王若楠, 高展, 孙继超, 马莹, 张恒, 贾春江, 徐政虎, 苑世领, 刘刚.
