| 1 | An environmental flow assessment method based on the relationships between flow and ecological response: A case study of the Three Gorges Reservoir and its downstream reach显示文摘The current environmental flow assessment of Chinese rivers is thought to have three shortcomings: The first is that environmental flow requirements of reservoirs in dammed rivers are usually not explicitly considered; the second is that enough attentions have not been paid to the inherent links between flow regime and ecological processes; the third is that most studies focus on the variable range of merely one hydrological element such as discharge needed by riverine ecosystems. Here, first proposed is a holistic method for environmental flow assessment, the flow-ecological response relationship method that is suitable for large rivers with relatively abundant ecological data. Based on the conceptual models and quantitative relationships between flow and ecological response, this method comprehensively considers the ecological conservation requirements of both reservoir and its downstream reach. Then, it is applied to assessing the environmental flows of the Three Gorges Reservoir and its downstream reach by the following steps: 1) Construction of conceptual models of flow-ecological response; 2) identification of ecological targets of environmental flows and their key periods; 3) development of the quantitative relationships between hydrological indicators and ecological indictors; 4) preliminary assessment of environmental flow according to the tradeoff between ecological targets and water demands of human. The environmental flow hydrographs obtained have explicit ecological conservation targets, time schedule of achieving each target, and characteristics of multiple hydrological elements such as flow, water level, frequency, timing, duration and rate of change. The case study has tested the reasonability and feasibility of this method, and the results of this study are expected to provide technical support and decision reference for improving the operation of the Three Gorges-Gezhouba cascade reservoirs. | WANG JunNa DONG ZheRen LIAO WenGen LI Chong FENG ShunXin LUO HuiHuang PENG QiDong | 2013 | Science China(Technological Sciences)2013，56，6： | 16 |
| 2 | Energy corrugation in atomic-scale friction on graphite revisited by molecular dynamics simulations显示文摘Although atomic stick–slip friction has been extensively studied since its first demonstration on graphite,the physical understanding of this dissipation-dominated phenomenon is still very limited. In this work, we perform molecular dynamics(MD) simulations to study the frictional behavior of a diamond tip sliding over a graphite surface. In contrast to the common wisdom, our MD results suggest that the energy barrier associated lateral sliding(known as energy corrugation) comes not only from interaction between the tip and the top layer of graphite but also from interactions among the deformed atomic layers of graphite. Due to the competition of these two subentries, friction on graphite can be tuned by controlling the relative adhesion of different interfaces.For relatively low tip-graphite adhesion, friction behaves normally and increases with increasing normal load. However,for relatively high tip-graphite adhesion, friction increases unusually with decreasing normal load leading to an effectively negative coefficient of friction, which is consistent with the recent experimental observations on chemically modified graphite. Our results provide a new insight into the physical origins of energy corrugation in atomic scale friction. | Xiao-Yu Sun Yi-Zhou Qi Wengen Ouyang Xi-Qiao Feng Qunyang Li | 2016 | Acta Mechanica Sinica2016，32，4： | 3 |
| 3 | A stable oxygen evolution splitting electrocatalysts high entropy alloy FeCoNiMnMo in simulated seawater显示文摘Stabilizing anode for oxygen evolution(OER)in chlorine-containing electrolytes is a significant challenge.Adding corrosion inhibitors in electrolytes can alleviate this problem,but the type and dosage of cor-rosion inhibitors need a lot of exploration,and side reactions may occur to reduce current efficiency.Herein,we prepared a FeCoNiMnMo High entropy alloy(HEA)electrode for OER in simulated seawa-ter without corrosion inhibitors.It exhibits great electrocatalytic activity(overpotential(η)=237 mV at 10 mA cm^(-2))and excellent stability(200 h at 100 mA cm^(-2)).Experiments and Density Functional The-ory(DFT)calculation show that the protective layer containing K_(2)MoO_(4)is the crucial factor for chlorine resistance of FeCoNiMnMo electrode.The tightly adsorbed state of Cl-and K_(2)MoO_(4)ensures that other oxides are not corroded.And the externally added K_(2)MoO_(4)cannot protect the electrode.In addition,the high-entropy effect of HEA reduces the dissolution of the alloy.This work provides an efficient way to prepare a noble-free HEA catalyst that can stabilize oxygen evolution in corrosive electrolytes. | Peng Li Yuanpeng Yao Wengen Ouyang Ze Liu Huayi Yin Dihua Wang | 2023 | Journal of Materials Science & Technology2023，，7： | 2 |
| 4 | Deducing the internal interfaces of twisted multilayer graphene via moiré-regulated surface conductivity显示文摘The stacking state of atomic layers critically determines the physical properties of twisted van der Waals materials.Unfortunately,precise characterization of the stacked interfaces remains a great challenge as they are buried internally.With conductive atomic force microscopy,we show that the moirésuperlattice structure formed at the embedded interfaces of small-angle twisted multilayer graphene(tMLG)can noticeably regulate surface conductivity even when the twisted interfaces are 10 atomic layers beneath the surface.Assisted by molecular dynamics(MD)simulations,a theoretical model is proposed to correlate surface conductivity with the sequential stacking state of the graphene layers of tMLG.The theoretical model is then employed to extract the complex structure of a tMLG sample with crystalline defects.Probing and visualizing the internal stacking structures of twisted layered materials is essential for understanding their unique physical properties,and our work offers a powerful tool for this via simple surface conductivity mapping. | Huan Wang Sen Wang Shuai Zhang Mengzhen Zhu Wengen Ouyang Qunyang Li | 2023 | National Science Review2023，10，8： | 0 |
| 5 | HPC-Atlas:Computationally Constructing A Comprehensive Atlas of Human Protein Complexes显示文摘A fundamental principle of biology is that proteins tend to form complexes to play important roles in the core functions of cells.For a complete understanding of human cellular functions,it is crucial to have a comprehensive atlas of human protein complexes.Unfortunately,we still lack such a comprehensive atlas of experimentally validated protein complexes,which prevents us from gaining a complete understanding of the compositions and functions of human protein complexes,as well as the underlying biological mechanisms.To fill this gap,we built Human Protein Complexes Atlas(HPC-Atlas),as far as we know,the most accurate and comprehensive atlas of human protein complexes available to date.We integrated two latest protein interaction networks,and developed a novel computational method to identify nearly 9000 protein complexes,including many previously uncharacterized complexes.Compared with the existing methods,our method achieved outstanding performance on both testing and independent datasets.Furthermore,with HPC-Atlas we identified 751 severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-affected human protein complexes,and 456 multifunctional proteins that contain many potential moonlighting proteins.These results suggest that HPC-Atlas can serve as not only a computing framework to effectively identify biologically meaningful protein complexes by integrating multiple protein data sources,but also a valuable resource for exploring new biological findings.The HPCAtlas webserver is freely available at http://gffzz6ca2edafa0dc406ahopx5cf9pvk5x6xxu.ffgz.tsg.suse.edu.cn/HPC-Atlas. | Yuliang Pan Ruiyi Li Wengen Li Liuzhenghao Lv Jihong Guan Shuigeng Zhou | 2023 | Genomics, Proteomics & Bioinformatics2023，21，5： | 0 |
