Single-atom catalyst has garnered widespread attention to mimic mature enzymes due to its well-defined atomic structure and coordination environments. However, since the carbon–carbon（C–C） coupling reactions require synergistic catalysis of multiple sites, single-atom catalysts suffer from insufficient active sites and unclear reaction mechanisms. Controlling the reaction intermediates in a precisely targeted pocket through careful metal–organic cage design is therefore crucial. Here, we prepare a tetrahedral [Cu6L4]-type boron–imidazolate cage integrating highly active Cu sites and optimized cavity, which exhibits enzyme like specific catalytic performance in electrochemical CO2reduction reaction（CO2RR） to enhance the selectivity of *** analyses and computational calculations suggest that the single Cu site together with neighboring boron–imidazolate ligands provides suitably synergistic effects that enable the energetically favorable formation of an *COCHO intermediate, a key step determining selectivity. As a result, the [Cu6L4]-type cage of BIC-145 achieves a Faradaic efficiency of 28% for C2H4maintaining an average current density of -3.54 mA cm-2over a 5-hour electrolysis period. This work represents the first example for studying single-metal site catalysts with ultra-low coordination numbers through the rational design of metal–organic cages.

理解缺陷消除机理对于制备无缺陷的长程有序嵌段共聚物薄膜至关重要.本文利用弦方法结合自洽平均场理论研究了接枝均聚物高分子刷在AB两嵌段共聚物垂直层薄膜的偶极位错缺陷消除中发挥的作用.研究发现,高分子刷的“浸润效应”和“重排效应”能够降低胁的有效值,增大跳跃扩散的扩散系数,进而促进“桥连”结构的形成.并且,接枝高分子刷的基底表面的“硬度”越小,以上2种效应越显著,越能进一步降低缺陷消除过程中形成“桥连”结构这一关键步骤的能垒.

目的设计一种鱼糜食品(福州鳗鱼丸)的常温包装技术,探究其在常温环境下品质变化与货架期的关系,从而判断其是否可替代低温贮藏技术来满足电商快递的要求。方法通过正交实验法复配一种由壳聚糖、丙酸钙与茶多酚组成的抑菌剂,涂布于PA/PE膜内层并制袋。通过微波干燥法降低鱼丸水分含量与初始菌落总数,然后采用真空包装常温贮藏。检测常温贮藏下鱼丸的挥发性盐基氮,并以此为依据建立常温状态下的货架期模型。同时检测相同条件下鱼丸的菌落总数,以验证该货架期模型的准确性及该包装技术的可行性。结果抗菌剂配方采用质量分数为3%的壳聚糖,0.15%的丙酸钙,0.3%的茶多酚,微波功率400 W,微波时间2 min,可取得较好效果,且常温环境下货架期预测模型较为准确。结论该常温包装技术的货架期在10 d以上,可以满足常温环境下鱼丸通过电商快递3~5 d送达的要求。

Sequence-activated chemiluminescence(CL) technique offers a unique approach to detecting specific biomolecules or cellular events with high sensitivity and spatial resolution. The fundamental principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under complex physiological conditions. This sequential activation could be triggered by enzymes, reactive oxygen species(ROS), biothiols or changes in the microenvironment. These unique sequence-activated CL probes bestow several advantages, including minimal background, deep-tissue penetration, and the ability of non-invasive or minimally invasive detection. The sequence-activated CL techniques represent a significant advancement in molecular imaging and diagnostics. In this mini-review, we focus on the latest developments in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and molecular recognition.
