李正名院士是我国著名的教育家、化学家和农药学家。在李先生逝世3周年之际，李正名奖学金捐赠暨首届颁奖仪式在南开大学举行。本文结合一部分典型的具体事例，对李正名先生的教育家精神和科学家精神进行了介绍，从中折射出他始终如一的坚定爱国信念和无私奉献精神。青年学子通过学习李先生的光辉事迹，可以深入了解老一辈科学家浓厚的家国情怀。本文有助于激励当代大学生厚植爱国主义理想与信念，增强自主创新意识和能力，立志为中华民族的伟大复兴贡献自己的全部力量。

吉林大学化学国家级实验教学示范中心对不同阶段的学生引入科普启迪、兴趣引导、实验训练等教学方式，从低到高，由浅入深，构建和实践了启蒙、引导、培养的全方位立体化实践育人模式，并取得了一定的成效。未来，中心将继续探索和实践化学拔尖人才的培养，以适应新时代下对具有批判创新思维的人才的需求。

随着社会对化学专业人才安全素养的要求日益提高，各高校逐渐意识到化学实验室安全教育的重要性。但当前的化学安全教育普遍缺乏系统性，为了扭转这样的局面，吉林大学化学学院依托化学国家级实验教学示范中心为平台，基于OBE (Outcome-Based Education)教育理念，以硬件建设和知识载体为双支撑、采取“理论与实践相结合、课内课外相结合、虚拟与现实相结合”的三结合实施路径，构建化学安全实践育人体系，使学生安全意识、安全知识和应急能力螺旋式上升，全面提升学生的化学安全素养。

Herein, a one-pot chemical reduction method was reported to prepare folic acid (FA)-stabilized silver nanoclusters (FA@Ag NCs), in which FA, hydrazine hydrate, and silver nitrate were used as capping agent, reducing agent, and precursor, respectively. Several technologies were employed to investigate the structures and optical properties of FA@Ag NCs, including transmission electron microscopy (TEM), X ray photoelectron spectrometer (XPS), Fourier transform infrared spectrometer (FTIR), X-ray diffractometer (XRD), fluorescence spectrometer, and ultraviolet visible absorption spectrometer. FA@Ag NCs were suggested to be highly dispersed and spherical with a size of around 2.8 nm. Moreover, the maximum excitation and emission wavelengths of FA@Ag NCs were 370 and 447 nm, respectively. Under the optimal detection conditions, FA@Ag NCs could be used to effectively detect malachite green with the linear detection range of 0.5-200 μmol·L^-1. The detection limit was 0.084 μmol·L^-1. The fluorescence-quenching mechanism was ascribed to the static quenching. The detection system based on FA@Ag NCs was successfully used for the detection of malachite green in actual samples with good accuracy and reproducibility.
