Converting CO_(2) into value-added chemicals and fuels through various catalytic methods to lower the atmospheric CO_(2) concentration has been developed to be a crucial means to alleviate the energy shortage and ameliorate the ever-fragile environment status. However, the complexity of the CO_(2) conversion reaction and the strong reduction conditions lead to the inevitable structural evolution, making it difficult for the prior design of suitable catalytic materials. Herein, to guide the rational design of efficient catalysts,we will be centered on the thermal, electro, and photo-induced structural evolution and active species identification during the CO_(2) conversion, including the in situ/operando characterization techniques monitoring the activation, steady, and deactivation stage of the catalysts as well as the inherent restructuring mechanism towards active species. Besides, the future challenges and opportunities on the merits of combining the structural evolution with the adsorbed intermediates recognized by ultra-fast spectroscopic techniques, simultaneously, the combination of theoretical simulation and the results of in situ experiments will also be addressed. This review can not only guide the identification of real active species, but also provide an approach to design the specific active species towards CO_(2) conversion, rather than only focusing on activity, for the purpose of practical industrial application.

Inverse vulcanized polymers(IVPs) that generated from elemental sulfur and smaller amounts of alkenes have found broad promising applications such as cathode materials for Li-S batteries, dynamic and repairable materials, optics applications, and metal sorption. However, their exploration in organic synthesis is still unprecedented. Here we first report the application of inverse vulcanized polymers in catalysis for organic transformations. A biomass-derived inverse vulcanized polymer(IVP-EAE) is found to be capable of catalyzing cross-coupling reactions in a transition-metal-free fashion under visible *** method allows the direct C–H functionalization of pyrroles and N-arylacrylamides with(hetero)aryl halides, respectively, leading to the formation of two sets of structurally important scaffolds including pyrrole-containing biaryls and 3,3-disubstituted oxindoles with high selectivity. We anticipate this study will not only unveil the new potential of IVPs, but also offer a distinct type of catalysts for organic transformations.

The UAV pursuit-evasion problem focuses on the efficient tracking and capture of evading targets using unmanned aerial vehicles (UAVs), which is pivotal in public safety applications, particularly in scenarios involving intrusion monitoring and interception. To address the challenges of data acquisition, real-world deployment, and the limited intelligence of existing algorithms in UAV pursuit-evasion tasks, we propose an innovative swarm intelligence-based UAV pursuit-evasion control framework, namely "Boids Model-based DRL Approach for Pursuit and Escape" (Boids-PE), which synergizes the strengths of swarm intelligence from bio-inspired algorithms and deep reinforcement learning (DRL). The Boids model, which simulates collective behavior through three fundamental rules, separation, alignment, and cohesion, is adopted in our work. By integrating Boids model with the Apollonian Circles algorithm, significant improvements are achieved in capturing UAVs against simple evasion strategies. To further enhance decision-making precision, we incorporate a DRL algorithm to facilitate more accurate strategic planning. We also leverage self-play training to continuously optimize the performance of pursuit UAVs. During experimental evaluation, we meticulously designed both one-on-one and multi-to-one pursuit-evasion scenarios, customizing the state space, action space, and reward function models for each scenario. Extensive simulations, supported by the PyBullet physics engine, validate the effectiveness of our proposed method. The overall results demonstrate that Boids-PE significantly enhance the efficiency and reliability of UAV pursuit-evasion tasks, providing a practical and robust solution for the real-world application of UAV pursuit-evasion missions.

在弱交流系统下对于附带有STATCOM的电网换相换流器高压直流输电(Line Commutated Converter based High Voltage Direct Current, LCC-HVDC)系统,存在着LCC逆变站与STATCOM之间耦合导致LCC-HVDC系统的稳定裕度下降问题,这会减弱LCC-HVDC抑制换相失败的能力。此外,HVDC控制环节之中的电压指令电流控制(voltage dependent current order limiter, VDCOL)环节的输出电流指令大幅剧烈波动还有几率会导致HVDC系统在首次换相失败之后发生后续换相失败。针对上述问题提出了一种“改进参考电压”的思想,对STATCOM和VDCOL的参考电压与输入电压分别进行修正。首先在STATCOM原本的参考电压经过一个“虚拟电抗”之后得到一个新的参考电压,通过这个改进参考电压弱化了STATCOM电压外环控制模块与LCC逆变站的耦合,减小了交流系统等效阻抗的大小,提升了系统对干扰的抵抗能力。然后对VDCOL的输入电压进行改进,新的改进输入电压改善了故障后VDCOL输出电流指令的大幅剧烈波动情况。最后通过三个层次的对照试验,验证了所提方法的有效性。

目的对国产与进口注射用头孢哌酮钠的质量现状进行评价。方法采用法定标准检验与探索性研究相结合,对国家药品抽检的66批次样品与调研企业收集的样品进行检验与分析。结果法定标准检验结果显示,66批次注射用头孢哌酮钠合格率为100%。探索性研究揭示,《中国药典》2020版标准的有关物质方法专属性较差,限度较宽,难以保证安全性,建立专属性较强的有关物质方法并可同时控制聚合物杂质;部分企业的样品检出微量的遗传毒性杂质NDMA,建议企业加强对原料生产的监控;国内样品晶体聚结较严重、粒度分布不均匀,复溶时间较长,提示国产原料的结晶工艺仍有提升空间;配伍结果显示部分制剂企业说明书中推荐的配伍稀释液的合理性值得商榷;综合影响因素与加速试验结果,结合各国药典的贮藏条件,表明统一规定该品种在凉暗处或25℃贮藏可能存在一定的风险;包材相容性结果显示覆膜胶塞与中硼硅玻璃瓶更能提升样品的质量。结论目前国产注射用头孢哌酮钠整体质量一般,质量标准有待提高,建议企业优化原料结晶工艺,同时选择质量更好的包材。
