1Hierarchical Manganese Oxide/Carbon Nanocomposites for Supercapacitor Electrodes显示文摘有装载的层次毛孔结构和可控制的 MnO2 的 MnO2/carbon nanocomposites 用一个自我限制的生长方法被综合了。这被 KMnO4 的氧化还原作用反应与包含层次毛孔的牺牲的碳底层完成。唯一的毛孔结构允许 nanocomposites 的合成,悦耳的 MnO2 装载直到 83 wt.% 。nanocomposites 的特定的电容增加了, MnO2 装载;在另一方面,电气化学的阻抗光谱学测量的传导性与增加装载的 MnO2 减少了。装载的 MnO2 的优化与高特定的电容和优秀的率能力导致了 nanocomposites。这个工作提供将为应用的一个大变化便于高效的 supercapacitor 材料的设计和制造的重要基本理解。Yiting Peng Zheng Chen Jing Wen Qiangfeng Xiao Ding Weng Shiyu He Hongbin Geng Yunfeng Lu 2011Nano Research2011,4,2:8
2High performance octahedral PtNi/C catalysts investigated from rotating disk electrode to membrane electrode assembly显示文摘Octahedral PtNi/C catalysts have demonstrated superior catalytic performance in oxyge n reduction reacti on (ORR) over commercial Pt/C with rotating disk electrode (RDE). However, it is not trivial to translate such promising results to real-world membrane-electrode assembly (MEA). In this work, we have synthesized octahedral PtNi/C catalysts using poly(diallyldimethylammonium chloride)(PDDA) as a capping age nt and in vestigated their performance from RDE to MEA. In RDE, mass activity and specific activity of the optimized octahedral PtNi/C catalyst for oxygen reduction reaction (ORR) are nearly 19 and 28 times high of the state-of-the-art commercial Pt/C, respectively. At MEA level, the octahedral PtNi/C catalyst exhibits excelle nt power generation performa nee and durability paired with commercial Pt/C ano de. Its cell voltage at 1,000mA·cm^-2 reaches 0.712 V, and maximum power density is 881.6 mW·cm^-2 and its performance attenuation is also less, around 11.8% and 7% under galvanostatic condition of 1,000 mA·cm^-2 for 100 h. Such results are investiaged by thermodynamic analysis and fundametal performance modeling, which indicate the single cell performance can be further improved by reducing the size of PtNi/C catalyst agglomerates. Such encouraging results have demonstrated the feasibility to convey the superior performance of octahedral PtNi/C from RDE to MEA.Bing Li Jue Wang Xin Gao Congwei Qin Daijun Yang Hong Lv Qiangfeng Xiao Cunman Zhang 2019Nano Research2019,12,2:3
3Rce1 expression in renal cell carcinoma and its regulatory effect on 786-O cell apoptosis through endoplasmic reticulum stress显示文摘(Rce1 ) 地岬和 a-factor-converting 酶 1 位于 endoplasmic 蜂窝胃(嗯) 并且被认为为绝大多数 CAAX 蛋白质处理的 endoproteolytic 负责。Endoplasmic 蜂窝胃应力(ERS ) 在肾的房间癌(RCC ) 起一个重要作用;然而,在 RCC 的 Rce1 的表示和角色广泛地没被学习。我们试图在 RCC 786-O 房间在嗯导致 apoptosis 在 RCC 纸巾和它的分子的机制调查 Rce1 的表示。我们首先使用了检测在肾的癌纸巾和 paracancerous 纸巾的 Rce1 表示的西方的弄污,量的反向的 transcriptase 聚合酶链反应,和 immunohistochemistry。Rce1 表示是在 RCC 的 upregulated,这被发现纸巾,和它的积极表示水平强烈与 clinicopathologic 特征被联系。下次,我们在人的胚胎的肾房间线 HEK293 和人的肾的癌房间线 786-O 检测了 Rce1 的表示, ACHN,和 A498。Rce1 的更高的表示在人的肾的癌房间线被发现,特别在 786-O 房间。在 786-O 房间的 Rce1 击倒增加的 apoptosisJianjun Li Delin Wang Junnan Liu Yunlang Qin Liangliang Huang Qiangfeng Zeng Maolin Xiao Jie Hu Qixin Yang Jiang He Li Mai Ying Li Wujiang Liu 2017Acta Biochimica et Biophysica Sinica2017,49,3:2

5Efficient Synthesis of PbTe Nanoparticle Networks显示文摘The synthesis of semiconductor nanocrystalline networks using weak capping ligands in aqueous media has been demonstrated.Carbohydrates,includingβ-cyclodextrin,D-(+)-glucose,D-glucosamine,lactobionic acid,sucrose,and starch were chosen as weak ligands to facilitate the formation of PbTe nanoparticle networks.The nanoparticle size,ranging from 5 nm to 30 nm,can be tuned by manipulating the temperature and concentration.Through a similar strategy,more complicated nanostructures including carbohydrate spheres@PbTe core-shell structures and Te@carbohydrate@PbTe multilayered submicron cables have been fabricated.This is a general approach which can be easily extended to the fabrication of other semiconductor networks,including PbSe and Bi2Te3 using carbohydrates and ethylenediaminetetraacetic acid(EDTA),respectively,as ligands.Qiangfeng Xiao Ding Weng Zhenglong Yang Javier Garay Minjuan Zhang Yunfeng Lu 2010Nano Research2010,3,10:1
