| 1 | MnO_(2) cathode materials with the improved stability via nitrogen doping for aqueous zinc-ion batteries显示文摘The research and exploration of manganese-based aqueous zinc-ion batteries have been controversial of cycle stability and mechanism investigation,thus improving the stability and exploring storage mechanism are still the most main issue.Defect engineering has become an effective method to improve cycle stability.Herein,a nitrogen-doped ε-MnO_(2)(MnO_(2)@N)has been prepared using electrochemical deposition and heat treatment under nitrogen atmosphere.As the cathode for zinc-ion batteries,the capacity retention rate of MnO_(2)@N cathode is close to 100%after 500 cycles at 0.5 A g^(-1),while the capacity retention rate for the initial MnO_(2) cathode is 62%.At 5 A g^(-1),the capacity retention rate of MnO_(2)@N cathode is 83%after 1000 cycles,which is much higher than the 27%capacity retention rate for the original MnO_(2) cathode.And it can be found that the oxygen vacancies increase after nitrogen doping,which can improve the conductivity of the MnO_(2)@N cathode.Also,there is Mn-N bond in MnO_(2)@N,which can enhance the electrochemical stability of MnO_(2)@N cathode.In addition,the electrochemical mechanism of MnO_(2)@N cathode has been explored by the CV,GCD and GITT tests.It is found that nitrogen doping promotes the intercalation of H^(+) and the corresponding capacity contribution.Compared with the original MnO_(2) cathode,the diffusion coefficient of H^(+) and Zn^(2+) in MnO_(2)@N cathode increases.Also,the reactions during the charging and discharging process are explored through the ex-situ XRD test.And this work may provide some new ideas for improving the stability of manganese-based zinc-ion batteries. | Yanan Zhang Yanpeng Liu Zhenhua Liu Xiaogang Wu Yuxiang Wen Hangda Chen Xia Ni Guohan Liu Juanjuan Huang Shanglong Peng | 2022 | Journal of Energy Chemistry2022，31，1： | 6 |
| 2 | MEK2 is a prognostic marker and potential chemo-sensitizing target for glioma patients undergoing temozolomide treatment显示文摘尽管 temozolomide (TMZ ) 是为 glioblastoma 的首要的化学疗法的代理人,它经常由于药抵抗是非药品。克服 glioblastoma 房间的抵抗到 TMZ,为结果预言识别预示的标记并且开发敏化 chemo 代理人是必要的。这里, TMZ 抵抗、 TMZ 敏感的样品的基因表示侧面被 microarray 分析,和激活 mitogen 的蛋白质 kinase kinase 比较(MEK2 ) 2 在抵抗 glioma 房间然而并非在敏感肿瘤房间或非肿瘤纸巾明确地是 upregulated。而且,耐心的数据的全面分析表明 MEK2 表示的增加的水平响应 TMZ 治疗与 glioma 等级和更坏的预后的前进相关很好。而且,在 U251 glioma 房间线或 xenografted glioma 减少 MEK2 的水平通过调停 shRNA 的基因为击倒的禁止的房间增长建模并且向 TMZ 治疗提高了房间的敏感。从由即时 PCR 的 glioma 病人的肿瘤样品的进一步的分析显示增加的 MEK2 表示水平仔细与许多药抵抗基因的激活被联系。最后,在 MEK2 是在 vitro 的 silenced 以后,这些抵抗基因是 downregulated,建议导致 MEK2 的 chemo 抵抗的机制能被这些抵抗基因的 transcriptional 激活调停。一起,我们的数据显示 MEK2 的表示水平能为 glioma 化疗用作一个预示的标记并且 MEK2 对手能被用作 chemo-sensitizers 提高 TMZ 的治疗功效。 | Hua He Maojin Yao Wenhao Zhang Bangbao Tao Feili Liu Shu Li Yan Dong Chenran Zhang Yicheng Meng Yuxin Li Guohan Hu Chun Luo Hui Zong Yicheng Lu | 2016 | Cellular & Molecular Immunology2016，13，5： | 1 |
