| 2 | Impact of eddies on ocean diapycnal mixing in Gulf Stream region显示文摘Based on high-resolution,Array for Real-time Geostrophic Oceanography(Argo)profiles and Sea Level Anomaly(SLA)data,this study statistically analyzes and compares turbulent diapycnal mixing profiles inside and outside mesoscale eddies in the Gulf Stream region.The result indicates that average diapycnal diffusivity at 300–540 m depths in anticyclonic eddies reaches4.0×10-5 m2 s-1.This is significantly higher than the 1.6×10-5 m2 s-1 outside eddies and 0.8×10-5 m2 s-1 in cyclonic eddies.Probabilities of diapycnal diffusivity greater than 10-4 m2 s-1 within anticyclonic and cyclonic eddies and outside eddies are29%,5%and 12%,respectively.However,magnitudes of average diapycnal diffusivity at 540–900 m depths in these three cases are of the same order,10-5 m2 s-1.Twenty-four of a total 38 anticyclonic eddies had enhanced mixing in the ocean interior,and 22 were observed during or shortly after strong winds.The coincidence between enhanced mixing and strong wind stress indicates that more wind-induced,near-inertial wave energy propagates downward in anticyclonic eddies.The deeper part of 12 profiles(below 540 m)in anticyclonic eddies had vertical overturns with Thorpe scale exceeding 5 m,among which three profiles had overturns reaching 20 m.Enhanced mixing may have occurred in deep layers of some profiles,although it was not evident in average conditions. | LI Min XIE LingLing YANG QingXuan TIAN JiWei | 2014 | Science China Earth Sciences2014,57,6: | 4 |
| 3 | Hierarchical coupling effect in hollow Ni/NiFe2O4-CNTs microsphere via spray-drying for enhanced oxygen evolution electrocatalysis显示文摘Design and fabrication of cost-effective transition metal and their oxides-based nanocomposites are of paramount significance for metal-air batteries and water-splitting.However,the traditional optimized designs for nanostructure are complicated,low-efficient and underperform for wide-scale applications.Herein,a novel hierarchical framework of hollow Ni/NiFe2O4-CNTs compositemicrosphere forcibly-assembled by zero-dimensional(OD)Ni/NiFo204 nanoparticle(<16 nm)and one-dimensional(1D)self-supporting CNTs was fabricated successfully.Benefitted from the unique nanostructure,such monohybrids can achieve remarkable oxygen evolution reaction(OER)performance in alkaline media with a low overpotential and superior durability,which exceeds most of the commercial catalysts based on IrO/RuO2 or other non-noble metal nanomaterials.The enhanced OER performance of Ni/NiFe2OA-CNTs composite is mainly ascribed to the increased catalytic activity and the optimized conductivity induced by the effects of strong hierarchical coupling and charge transfers between CNTs and Ni/NiFe204 nanoparticles.These effects are greatly boosted by the polarized heterojunction interfaces confirmed by electron holography.The density functional theory(DFT)calculation indicates the epitaxial Ni further enriches the intrinsic electrons contents of NiFe204 and thus accelerates absorption/desorption kinetics of OER intermediates.This work hereby paves a facile route to construct the hollow composite microsphere with excellent OER electrocatalytic activity based on non-noble metal oxide/CNTs. | Xuefeng Yu Guanyu Chen Yizhe Wang Jiwei Liu Ke Pei Yunhao Zhao Wenbin You Lei Wang Jie Zhang Linshen Xing Jingjun Ding Guangzhou Ding Min Wang Renchao Che | 2020 | Nano Research2020,13,2: | 3 |
| 4 | Quantitative Evaluation of Fatigue Crack Size Using Eddy Current Pulsed Thermography显示文摘A set of metallic specimens containing fatigue cracks with different sizes were tested using eddy current pulsed thermography(ECPT),therefore the relations between heating response of the crack area and the crack length was studied.The numerical and experimental results both showed that the increase of the crack length enhanced the crack heating response under specific test conditions.A particular form of calculated response signal,which is linearly related to the crack length,was introduced to provide a quantitative evaluation of crack length. | Feng Fuzhou Xu Chao Zhu Junzhen Min Qingxu Sun Jiwei | 2017 | Transactions of Nanjing University of Aeronautics and Astronautics2017,34,3: | 1 |
| 5 | MDIG-mediated H3K9me3 demethylation upregulates Myc by activating OTX2 and facilitates liver regeneration显示文摘The mineral dust-induced gene(MDIG)comprises a conserved JmjC domain and has the ability to demethylate histone H3 lysine 9 trimethylation(H3K9me3),Previous studies have indicated the significance of MDIG in promoting cell proliferation by modulating cell-cycle transition.However,its involvement in liver regeneration has not been extensively investigated.In this study,we generated mice with liver-specific knockout of MDIG and applied partial hepatectomy or carbon tetrachloride mouse models to investigate the biological contribution of MDIG in liver regeneration. | Jinpeng Du Wenwei Liao Haichuan Wang Guimin Hou Min Liao Lin Xu Jiwei Huang Kefei Yuan Xiangzheng Chen Yong Zeng | 2023 | Signal Transduction and Targeted Therapy2023,8,10: | 1 |
| 6 | Hierarchical metal-peptide assemblies with chirality-encoded spiral architecture and catalytic activity显示文摘We report the coordination assembly of the ferrocene-diphenylalanine(Fc-FF)with divalent copper ions(Cu^(2+))into metalpeptide assemblies(MPAs)with hierarchical spiral architectures.The MPA particles are composed of helically organized nanofibers which can be correlated to the logarithmic spirals.The MPAs are hierarchically porous with abundant Fc and Cu2+active sites and show much higher catalytic activity than natural laccase toward the decolorization reaction.Moreover,a series of hierarchical structures of the MPAs can be synthesized by controlling the temperature and enantiomeric excess(ee).The peptide enantiomers with higher ee values will self-assemble into highly complex and ordered structures,which show higher surface area and porosity and thus enhanced catalytic activity compared with those assembled by peptides with lower ee values.The results provide new insights into the vital role of chirality in directing the self-assembly of biomolecules into highly ordered complex functional structures. | Jiayu Liu Jiaxing Zhang Liwei Zhang Yuefei Wang Hao Wei Yuhe Shen Jiwei Min Xi Rong Wei Qi Rongxin Su Zhimin He | 2023 | Science China Chemistry2023,66,1: | 0 |
