| 2 | Ultrathin-shell epitaxial Ag@Au core-shell nanowires for high-performance and chemically-stable electronic, optical, and mechanical devices显示文摘Silver nanowires (AgNWs) hold great promise for applications in wearable electronics, flexible solar cells, chemical and biological sensors, photonic/plasmonic circuits, and scanning probe microscopy (SPM) due to their unique plasmonic, mechanical, and electronic properties. However, the lifetime, reliability, and operating conditions of AgNW-based devices are significantly restricted by their poor chemical stability, limiting their commercial potentials. Therefore, it is crucial to create a reliable oxidation barrier on AgNWs that provides long-term chemical stability to various optical, electrical, and mechanical devices while maintaining their high performance. Here we report a room-temperature solution-phase approach to grow an ultra-thin, epitaxial gold coating on AgNWs to effectively shield the Ag surface from environmental oxidation. The Ag@Au core-shell nanowires (Ag@Au NWs) remain stable in air for over six months, under elevated temperature and humidity (80 °C and 100% humidity) for twelve weeks, in physiological buffer solutions for three weeks, and can survive overnight treatment of an oxidative solution (2% H2O2). The Ag@Au core-shell NWs demonstrated comparable performance as pristine AgNWs in various electronic, optical, and mechanical devices, such as transparent mesh electrodes, surface-enhanced Raman spectroscopy (SERS) substrates, plasmonic waveguides, plasmonic nanofocusing probes, and high-aspect-ratio, high-resolution atomic force microscopy (AFM) probes. These Au@Ag core-shell NWs offer a universal solution towards chemically-stable AgNW-based devices without compromising material property or device performance. | Yangzhi Zhu Sanggon Kim Xuezhi Ma Peter Byrley Ning Yu Qiushi Liu Xiaoming Sun Da Xu Sangshan Peng Martin C.Hartel Shiming Zhang Vadim Jucaud Mehmet R.Dokmeci Ali Khademhosseini Ruoxue Yan | 2021 | Nano Research2021，14，11： | 1 |
| 3 | Reactive template-derived interfacial engineering of CoP/CoO heterostructured porous nanotubes towards superior electrocatalytic hydrogen evolution显示文摘The development of economical,efficient,and robust electrocatalysts toward the hydrogen evolution reaction(HER)is highly imperative for the rapid advancement of renewable H2 energy-associated technologies.Extensive utilization of the heterointerface effect can endow the catalysts with remarkably boosted electrocatalytic performance due to the modified electronic state of active sites.Herein,we demonstrate deliberate crafting of CoP/CoO heterojunction porous nanotubes(abbreviated as CoP/CoO PNTs hereafter)using a self-sacrificial template-engaged strategy.Precise control over the Kirkendall diffusion process of the presynthesized cobalt–aspartic acid complex nanowires is indispensable for the formation of CoP/CoO heterostructures.The topochemical transformation strategy of the reactive templates enables uniform and maximized construction of CoP/CoO heterojunctions throughout all the porous nanotubes.The establishment of CoP/CoO heterojunctions could considerably modify the electronic configuration of the active sites and also improve the electric conductivity,which endows the resultant CoP/CoO PNTs with enhanced intrinsic activity.Simultaneously,the hollow and porous nanotube architectures allow sufficient accessibility of exterior/interior surfaces and molecular permeability,drastically promoting the reaction kinetics.Consequently,when used as HER electrocatalysts,the well-designed CoP/CoO PNTs show Pt-like activity,with an overpotential of only 61 mV at 10mA cm^(−2) and excellent stability in 1.0M KOH medium,exceeding those of the vast majority of the previously reported nonprecious candidates.Density functional theory calculations further substantiate that the construction of CoP/CoO heterojunctions enables optimization of the Gibbs free energies for water adsorption and H adsorption,resulting in boosted HER intrinsic activity.The present study may provide in-depth insights into the fundamental mechanisms of heterojunction-induced electronic regulation,which may pave the way for the rational design of advanced Earth-abundant electrocatalysts in the future. | Qixing Zhou Ruoxu Sun Yiping Ren Run Tian Jun Yang Huan Pang Kai Huang Xinlong Tian Lin Xu Yawen Tang | 2023 | Carbon Energy2023，5，1： | 1 |
| 4 | 淋巴细胞密度及分布与直肠癌新辅助治疗反应的关系显示文摘背景:研究认为,淋巴细胞密度与直肠癌预后相关;但新辅助治疗前淋巴细胞分布模式对预后的影响尚不清楚。本研究旨在评估淋巴细胞的分布及密度与直肠癌新辅助治疗反应的关系。方法:对前瞻性队列中接受新辅助治疗的134例直肠癌患者进行回顾性分析。对新辅助治疗前活检标本进行免疫组化染色(CD4和CD8)。评估瘤内腺体周围淋巴细胞(IPL)和肿瘤浸润淋巴细胞(TIL)的密度。采用logistic回归模型(包括临床病理特征、分子特征及治疗方案)评估不同淋巴细胞的密度与肿瘤退缩分级(TRG)的关系。结果:CD8^(+)TIL密度高的患者接受新辅助治疗后获得了更佳的TRG(OR=0.23,95%CI:0.07-0.76,P<0.001)。而CD8^(+)IPL(P=0.033)、CD4^(+)IPL(P=0.156)和CD4^(+)TIL(P=0.170)则与TRG无明显相关性。敏感性分析未发现CD8^(+)TIL与新辅助放疗(P_(相互作用)=0.831)或化疗(P_(交互作用)=0.879)对TRG的影响存在交互作用。结论:本研究结果显示,CD8^(+)TIL而不是CD8^(+)IPL,可独立影响直肠癌新辅助治疗反应,这种影响不受放疗或化疗方案的干扰。 | Sicong Lai Xiaoying Lou Xinjuan Fan Weipeng Sun Yanhong Deng Jianping Wang Yan Huang Ruoxu Dou | 2020 | Gastroenterology Report2020，8，6： | 1 |
