酰胺合成是有机化学重要的研究方向之一。将国际前沿的酰胺合成方法引入到基础有机化学实验教学中可以丰富教学内容并促进本科教学与科研成果之间的融合。本文报道了一个以氮杂环卡宾催化醛的极性反转为知识重点的酰胺合成实验，以苯甲醛、亚硝基苯为原料，在无水无氧条件下实现了N-羟基-N-苯基苯甲酰胺的高效合成。该实验利用薄层色谱对反应过程进行监测，并通过红外、核磁共振波谱确定了产物结构。该实验具有操作简单、反应条件温和、高原子经济性、可重复性好等特点，非常适用于本科生实验教学。本实验将极性反转这一重要概念与氮杂环卡宾催化这一科学前沿有机结合起来，有利于激发和培养学生的科研兴趣。

在pH = 5缓冲溶液条件下，对仅有Co²⁺、仅有Ni²⁺、Co²⁺与Ni²⁺混合三种情况下Co²⁺的萃取率进行了探究。结果显示单独萃取Co²⁺时萃取率高达75.47%；然而对于混合溶液，萃取率较单独萃取Co²⁺明显下降。通过系列对比实验发现Ni²⁺的存在对Co²⁺的分光光度测量造成了干扰。因此，在综合性实验中我们利用分光光度法针对Co²⁺的萃取率进行分析，以及对可能影响萃取率的因素——pH、萃取时间、萃取次数进行了探究，寻找最佳实验条件，提高萃取率。

利用溶胶凝胶法制备出一种三角形Au@TiO₂核壳材料。经过水热晶化，该材料膨胀至300 nm，壳层TiO₂晶化为介孔锐钛矿相，但核心三角形Au颗粒的形貌保持不变。采用粉末X射线衍射(PXRD)、ζ电位、高分辨透射电子显微镜(HRTEM)、热重分析(TGA)、光致发光(PL)光谱、光电流(i-t)以及光催化降解技术，对样品的结构和性能进行了系统、详细的检测与分析。经过晶化处理的Au@TiO₂在可见光波段的光降解亚甲蓝性能比未晶化时有了显著的提升, 1 mg·mL^-1 Au@c-TiO₂可以在可见光照射1 h后实现对60 mg·L^-1亚甲蓝全降解。电子顺磁共振(EPR)测试表明·O₂^-和·OH两种自由基对光降解起到了很大作用。通过综合分析实验结果和时域有限差分(FDTD)分析，探究了催化反应的机理。

为了强化本科生拔尖人才的个性化培养，将高水平的科研资源转化为人才培养的教学资源，北京航空航天大学开设了科教融合的“科研课堂”微课题设计实验课程。本文以开设的“金属氧化物亚纳米材料的合成及其在电池储能方面的研究”微课题为例，从教学方法、课程内容、成绩评定和学生反馈等多个环节进行实践和探索。通过充分发挥教师指导、学生主体的优势，科研型教学模式的实施为拓展本科生科研思维、激发科研兴趣、提升科研创新能力提供了有益借鉴。

Using 2-dicyanomethylene-3-cyano-4, 5, 5-trimethyl-2, 5-dihydrofuran (TCF) as a near-infrared fluorescent chromophore, we designed and synthesized a TCF-based fluorescent probe TCF-NS by introducing 2, 4-dinitrophenyl ether as the recognized site for H₂S. The probe TCF-NS displayed a rapid-response fluorescent against H₂S with high sensitivity and selection but had no significant fluorescence response to other biothiols. Furthermore, TCF-NS was applied to sense H₂S in living cells successfully with minimized cytotoxicity and a large Stokes shift.

Three efficient methods for the synthesis of a series of Cu(Ⅱ) and Cu(Ⅰ) complexes based on imidazo[1,5-a] pyridine derivatives were developed. These methods include the following: (ⅰ) Cu(Ⅱ) salts were used as metal sources and N, N-dimethylformamide was employed as a solvent as well as a reductant to produce Cu(Ⅰ) complexes. (ⅱ) An iodidecontaining compound was utilized as a ligand and iodide source to prepare complexes. An in situ metalligand reaction occurred and an iodide-bridged copper complex was generated. (ⅲ) A series of aldehydes were added to the reaction systems to induce in situ metal-ligand reactions between the aldehydes and the imidazo[1,5-a]pyridine derivatives, producing polydentate ligand scaffolds. Eight complexes were prepared and characterized. The catalytic activities of these complexes toward the ketalization of ketones by ethylene glycol were investigated. With the exception of complex 4, the remaining seven complexes all showed high catalytic activity. The lower activity of 4 may be due to the larger radius of bridging iodide ions and the shorter Cu(Ⅰ)…Cu(Ⅰ) distance.
