The equivalent lumped-element circuit model was established, with the effective conductivity employed for impedance extraction. The impacts of CNT filling ratio, temperature, and other geometrical parameters on the performance were *** sensitivity analysis of Cu/CNT composite TSVs was carried out. The electrical performance of Cu/CNT composite TSVs were optimized by utilizing low-permittivity dielectrics or even air-gap.

随着胆道外科现代诊疗体系的建立与科学研究范式的转变, 无论是良性还是恶性胆道疾病, 均已进入精准化、个体化、全程化及多学科协作的诊疗和研究阶段。然而胆道外科医师仍面临着两大困境:(1)外科技术在降低良性胆道疾病致残率、提高胆道肿瘤患者生存率方面进入了瓶颈期;(2)对于"切胆保胆""如何减黄"等临床争议, 传统的临床研究似乎难以给出确切答案。借鉴系统生物学的理念, 作者提出了"胆道生态系统"的概念框架:胆管是丛林, 血管、淋巴管、神经和免疫系统是土壤, 干细胞是种子, 胆汁是河流, 肝细胞是河流的发源地。良恶性疾病具有动态转化的特征;不同部位的胆管构成"大"环境, 胆汁形成"小"环境, 不同细胞组成"微"环境;细胞亚群具有不同状态及多样性, 并受复杂分子信号网络的调控。作者据此进一步凝练了胆道外科的若干关键科学问题, 提出了优化研究范式的建议, 旨在从全局视角推动学科交叉融合, 推动胆道外科临床及转化研究。

Dense Nb/Nb5Si3 composites were fabricated via spark plasma sintering technology using Nb, Si, and Al elemental powders as raw materials. The microstructttres of the synthesised composites were analyzed through scanning electron microscopy, X-ray diffraction, and electron probe microanalysis. The results show that the composites consisted of residual Nb particle phase and Nb5Si3 phase. The microstructure of the Nb/ Nb5Si3 in situ composites was evidently affected by Al addition, which prompted the formation of the Al3Nb10Si3 phase. In addition, the Rockwell hardness of the composites decreased with the increase in AI additions. The Rockwell hardness of Nb-20Si is 60HRC, which decreased to approximately 52.7 HRC when the Al content increased to 15 at%. The oxidation resistance of the Nb/NbsSi3 in situ composites significantly improved with the increase in Al addition.
