| 1 | Fe5C2 nanoparticles as low-cost HER electrocatalyst:the importance of Co substitution显示文摘Constructing and understanding the doping effect of secondary metal in transition metal carbide(TMC)catalysts is pivotal for the design of low-cost hydrogen evolution reaction(HER) electrocatalysts. In this work, we developed a wet-chemistry strategy for synthesizing Co-modified Fe_5C_2 nanoparticles((Fe_(1-x)Cox)_5C_2 NPs) as highly active HER electrocatalysts in basic solution. The structure of(Fe_(1-x)Cox)_5C_2 NPs was characterized by X-ray diffraction(XRD), extended X-ray absorption fine structure spectra(EXAFS) and scanning/transmission electron microscopy(S/TEM), indicating that the isomorphous substitution of cobalt in the lattice of Fe_5C_2.(Fe_(0.75) Co_(0.25))_5C_2 exhibited the best HER activity(174 mV for j = -10 mA/cm^2). Computational calculation results indicate that Co provides the most active site for HER. X-ray adsorption spectra(XAS) studies further suggested that the electron transfer in Fe–C bonds are enhanced by the substitution of Co, which modulates the hydrogen adsorption on the adjacent electronic-enriched carbon, and therefore promotes HER activity. Our results affirm the design of lowcost bimetallic TMCs based HER catalysts. | Siwei Li Pengju Ren Ce Yang Xi Liu Zhen Yin Weizhen Li Hanjun Yang Jian Li Xiaoping Wang Yi Wang Ruochen Cao Lili Lin Siyu Yao Xiaodong Wen Ding Ma | 2018 | Science Bulletin2018，63，20： | 6 |
| 2 | Effects of Normalized Difference Vegetation Index and Related Wavebands′ Characteristics on Detecting Spatial Heterogeneity Using Variogram-based Analysis显示文摘Spatial heterogeneity is widely used in diverse applications, such as recognizing ecological process, guiding ecological restoration, managing land use, etc. Many researches have focused on the inherent scale multiplicity of spatial heterogeneity by using various environmental variables. How these variables affect their corresponding spatial heterogeneities, however, have received little attention. In this paper, we examined the effects of characteristics of normalized difference vegetation index (NDVI) and its related bands variable images, namely red and near infrared (NIR), on their corresponding spatial heterogeneity detection based on variogram models. In a coastal wetland region, two groups of study sites with distinct fractal vegetation cover were tested and analyzed. The results show that: 1) in high fractal vegetation cover (H-FVC) area, NDVI and NIR variables display a similar ability in detecting the spatial heterogeneity caused by vegetation growing status structure; 2) in low fractal vegetation cover (L-FVC) area, the NIR and red variables outperform NDVI in the survey of soil spatial heterogeneity; and 3) generally, NIR variable is ubiquitously applicable for vegetation spatial heterogeneity investigation in different fractal vegetation covers. Moreover, as variable selection for remote sensing applications should fully take the characteristics of variables and the study object into account, the proposed variogram analysis method can make the variable selection objectively and scientifically, especially in studies related to spatial heterogeneity using remotely sensed data. | WEN Zhaofei ZHANG Ce ZHANG Shuqing DING Changhong LIU Chunyue PAN Xin LI Huapeng SUN Yan | 2012 | Chinese Geographical Science2012，22，2： | 4 |
| 3 | Multi-omic characterization of genome-wide abnormal DNA methylation reveals diagnostic and prognostic markers for esophageal squamous-cell carcinoma显示文摘This study investigates aberrant DNA methylations as potential diagnosis and prognosis markers for esophageal squamous-cell carcinoma(ESCC),which if diagnosed at advanced stages has<30%five-year survival rate.Comparing genome-wide methylation sites of 91 ESCC and matched adjacent normal tissues,we identified 35,577 differentially methylated CpG sites(DMCs)and characterized their distribution patterns. | Yiyi Xi Yuan Lin Wenjia Guo Xinyu Wang Hengqiang Zhao Chuanwang Miao Weiling Liu Yachen Liu Tianyuan Liu Yingying Luo Wenyi Fan Ai Lin Yamei Chen Yanxia Sun Yulin Ma Xiangjie Niu Ce Zhong Wen Tan Meng Zhou Jianzhong Su Chen Wu Dongxin Lin | 2022 | Signal Transduction and Targeted Therapy2022，7，3： | 2 |

| 5 | Is oral microbiome of children able to maintain resistance and functional stability in response to short-term interference of ingesta?显示文摘Dear Editor,A series of studies had focused on the ecological stability of human microbiome(Lozupone et al.,2012;Faith et al.,2013;Moya and Ferrer,2016).Despite the continuous perturbation and the highly personalized composition within the human microbiome(Human Microbiome Project,2012),healthy adults stably maintain their microbial communities in terms of space and time(Faith et al.,2013;Moya and Ferrer,2016;Oh et al.,2016).This stability is proved to be critical for the well-being of human body(Lozupone et al.,2012).On the contrary,major shifts in microbial community composition are often related to diseases(Lynch and Pedersen,2016). | Fangqiao Wei Xiangyu Sun Yufeng Gao Haoyu Dou Yang Liu Lili Su Haofei Luo Ce Zhu Qian Zhang Peiyuan Tong Wen Ren Zhe Xun Ruochun Guo Yuanlin Guan Shenghui Li Yijun Qi Junjie Qin Feng Chen Shuguo Zheng | 2021 | Protein & Cell2021，12，6： | 1 |

| 17 | VAV2 is required for DNA repair and implicated in cancer radiotherapy resistance显示文摘Radiotherapy remains the mainstay for treatment of various types of human cancer;however,the clinical efficacy is often limited by radioresistance,in which the underlying mechanism is largely unknown.Here,using esophageal squamous cell carcinoma(ESCC)as a model,we demonstrate that guanine nucleotide exchange factor 2(VAV2),which is overexpressed in most human cancers,plays an important role in primary and secondary radioresistance.We have discovered for the first time that VAV2 is required for the Ku70/Ku80 complex formation and participates in non-homologous end joining repair of DNA damages caused by ionizing radiation. | Weiling Liu Chuanwang Miao Shaosen Zhang Yachen Liu Xiangjie Niu Yiyi Xi Wenjia Guo Jiahui Chu Ai Lin Hongjin Liu Xinyu Yang Xinjie Chen Ce Zhong Yuling Ma Yuqian Wang Shihao Zhu Shuning Liu Wen Tan Dongxin Lin Chen Wu | 2021 | Signal Transduction and Targeted Therapy2021，6，9： | 1 |
