采用高温固相法在1 050℃下烧结，制备了LiCoO₂低浓度梯度改性样品，分别为LiF掺杂包覆（LCOLF、LCO@LF）和MgF₂掺杂包覆（LCOMF、LCO@MF）。通过光电子能谱、透射电子显微镜和电化学技术等表征方法，对比分析材料形貌及电化学性能。结果表明，体相掺杂复合电极中，LCOLF热重测试显示出最优热稳定性，LCOMF晶体中（003）和（104）晶面间距收缩；45℃下1C倍率循环70圈后，LCOLF和LCOMF比容量分别为141.45和166.98 mAh·g^-1，循环性能优于LiCoO₂。表面包覆复合电极中，LCO@LF和LCO@MF晶粒表面光洁且晶格氧键价都向更高结合能方向增强；LCO@MF构建了坚实且紧密的包覆层，循环70圈后，放电比容量和容量保持率分别为183 mAh·g^-1和91.26%（LCO@LF分别为154.38 mAh·g^-1和77.54%），循环性能显著优于体相掺杂。

酒石酸及其衍生物可作为手性拆分剂拆分外消旋化合物，现有拆分实验较复杂且现象不直观。本实验为改进实验，以苯胺与外消旋酒石酸反应生成铵盐，通过拆分试剂、结晶溶剂和温度等反应条件的优化，获得了可视化的L型和D型酒石酸苯胺铵盐晶体，分别再进行碱性水解，酸化获得D-(−)-酒石酸和L-(+)-酒石酸。运用圆二色谱、旋光仪和核磁共振波谱等多种手段对拆分的晶体进行表征和确证。本改进实验立足于通过宏观现象反映微观本质，便于学生对手性(分子)概念的理解和掌握。

Four new coordination polymers, {[Cd(mbtx)(4OHphCOO)]NO₃}_n (1), {[Zn(mbtx)(1, 4‐bdc)_0.5(H₂O)₂]·(1, 4‐bdc)_0.5·4H₂O}_n (2), {[Cd₂(mbtx)(5NO₂‐bdc)₂(H₂O)₃]·4.5H₂O}_n (3), and {[Zn(H₂O)₆][Zn₂(mbtx)₂(btc)₂(H₂O)₄]·2H₂O}_n (4) (mbtx=1, 3‐bis(4H‐1, 2, 4‐triazole)benzene, 4OHphCOO^-=p‐hydroxybenzoate, 1, 4‐bdc^2-=1, 4‐benzenedicarboxylate, 5NO₂‐bdc^2-=5‐nitro‐isophthalate, btc^3-=1, 3, 5‐benzenetricarboxylate), were synthesized under room temperature condition and characterized by single‐crystal X‐ray diffraction, elemental analyses, and powder X‐ray diffraction. Single‐crystal X‐ray structural analysis shows that complexes 1 and 3 are 2D networks. In 1, the adjacent 2D networks are linked to a 3D network by π‐π stacking interaction. 2 and 4 exhibit 1D chains, and the 1D chains are connected into a 3D network by π‐π stacking interaction and intermolecular hydrogen bond. Luminescence and thermogravimetric analysis of the four complexes were discussed.
