Massive efforts have been concentrated on the advance of eminent near-infrared(NIR) photothermal materials(PTMs) in the NIR-Ⅱ window(1000–1700 nm), especially organic PTMs because of their intrinsic biological safety compared with inorganic PTMs. However, so far, only a few NIR-Ⅱresponsive organic PTMs was explored, and their photothermal conversion efficiencies(PCEs) still remain relatively low. Herein, donor–acceptor conjugated diradical polymers with open-shell characteristics are explored for synergistically photothermal immunotherapy of metastatic tumors in the NIR-Ⅱ window. By employing side-chain regulation, the conjugated diradical polymer TTB-2 with obvious NIR-Ⅱ absorption was developed, and its nanoparticles realize a record-breaking PCE of 87.7% upon NIR-Ⅱ light illustration. In vitro and in vivo experiments demonstrate that TTB-2 nanoparticles show good tumor photoablation with navigation of photoacoustic imaging in the NIR-Ⅱ window, without any side-effect. Moreover, by combining with PD-1 antibody,the pulmonary metastasis of breast cancer is high-effectively prevented by the efficient photo-immunity effect. Thus, this study explores superior PTMs for cancer metastasis theranostics in the NIR-Ⅱ window, offering a new horizon in developing radical-characteristic NIR-Ⅱ photothermal materials.

基于知识产权示范城市建设这一“准自然实验”,应用双重差分模型系统评估知识产权治理对数字创新韧性的影响机制。结果表明:知识产权治理可驱动数字创新韧性提升,且该作用具有时间滞后与动态效应。作用机制检验发现,知识产权治理可通过促进数字产业集聚、财政科技支出扩容、人力资本升级等路径,间接驱动数字创新韧性提升。异质性分析结果证实,知识产权治理对高水平数字政府、大型城市及胡焕庸线东部城市的数字创新韧性提升作用更为显著。因此,提出布设知识产权示范城市交织化网络、加快推进数字产业“聚链成群”、纵深推进数字政府建设的建议,为切实提升数字创新韧性提供新思路。

《刑法修正案(十二)》从依法惩治民营企业内部人员背信犯罪和进一步从严惩治行贿犯罪两个方面对刑法作出局部重要修改补充。增加规定民营企业内部人员相关背信罪名符合当前形势和需要,对于依法保护、平等保护企业和企业家利益具有重要现实意义。本次修改坚持问题导向和稳妥推进原则,对三个条文作了修改补充。实践中应当正确理解有关犯罪构成要件,准确把握相关政策尺度,依法精准惩治犯罪。加大惩治行贿犯罪是“坚持受贿行贿一起查”重要政策的立法体现。执法司法工作中要准确理解把握有关修改规定和精神,从严查办重点行贿,解决对行贿惩处失之于宽、不利于切断受贿犯罪因果链的问题。

微电网规模随着新能源渗透比例的提高与日剧增,然而由于缺乏灵活的能量转移机制,针对单个微电网的低碳经济调度优化效果有限。有效利用多微网系统内部的结构差异,实现能源在空间与时间双重维度上的流动对促进新能源电力系统低碳经济发展具有重要意义。为此,该文在考虑多微网功能区差异的基础上,运用纳什谈判思想,制定了计及电、热、碳能源交易的多微网系统优化调度策略。首先,针对微网功能区差异性构建基于居民区、商业区与工业区的多微网系统运行框架;其次,根据不同功能区的负荷特性构建了计及电、热负荷可替代性的需求响应模型;最后,以纳什谈判思想为基础,结合交替方向乘子法与商业求解器达成多微网间电、热、碳互利共赢的交易策略。算例分析验证了所提方案能够在实现多微网隐私保护的前提下全面提高系统运行的低碳性与经济性。
