| 1 | Insight into fouling behavior of poly(vinylidene fluoride)(PVDF)hollow fiber membranes caused by dextran with different pore size distributions显示文摘Membrane fouling is the key problem that occurs in membrane process for water treatment. However, how membrane microstructure influences the fouling behavior is still not clear. In this study, fouling behavior caused by dextran was deeply and systematically investigated by employing four poly(vinylidene fluoride)(PVDF)membranes with different pore sizes, ranging from 24 to 94 nm. The extent of fouling by dextran was accurately characterized by pore reduction, flux decline, and the change of critical flux. The result shows that membrane with the smallest pore size of 24 nm experienced the smallest fouling rate and the lowest fouling extent. As the membrane pore size increased, the critical flux ranges were 105-114, 63-73, 38-44 and 34-43 L·m^(-2)·h^(-1),respectively. The critical flux and fouling resistances indicated that the fouling propensity increases with the increase of membrane pore size. Two pilot membrane modules with mean pore size of 25 nm and 60 nm were applied in membrane filtration of surface water treatment. The results showed that serious irreversible membrane fouling occurred on the membrane with pore size of 60 nm at the permeate flux of40.5 L·m^(-2)·h^(-1).On the other hand, membrane with pore size of 25 nm exhibited much better anti-fouling performance when permeate flux was set to 40.5,48 and 60 L·m^(-2)·h^(-1). | Kailiang Zeng Jie Zhou Zhaoliang Cui Yue Zhou Chuan Shi Xiaozu Wang Liyue Zhou Xiaobin Ding Zhaohui Wang Enrico Drioli | 2018 | Chinese Journal of Chemical Engineering2018，26，2： | 9 |
| 2 | Coil-levitated hybrid generator for mechanical energy harvesting and wireless temperature and vibration monitoring显示文摘The development of wireless monitoring is currently restricted by the short lifetime of batteries,requiring frequent replacement.Utilization of abundant mechanical energy from the surrounding environment has attracted increasing attention in real-time monitoring.Herein,a coil-levitated hybrid generator was developed for the efficient harvesting of mechanical energy from mechanical motion.The novel coil-levitated structure adapted to the metal and magnetic environment.The output currents were systematically analyzed at different operation modes based on the unique combination of triboelectrification,electromagnetic induction,and piezoelectric effect.Under the excitation of vibration frequency and amplitude of 8 Hz and 5 mm respectively,the as-constructed triboelectric nanogenerator delivered a peak power density of 11.40 W/m3 at 10 MΩ.Meanwhile,the middle electromagnetic part and bottom piezoelectric generator provided peak power densities of 6.97 and 79.93 W/m2 at 10000Ω,respectively.More importantly,the battery charging experiment was verified,in which a 30 mA h Li-ion battery can be charged from 2.57 to 3.27 V in about 90 min.In sum,a self-powered temperature and vibration monitoring system was successfully developed based on hybrid generator,promising for realizing wireless monitoring of mechanical equipment without any external power supply. | XUE XiaoBin ZHANG ZengXing WU Bin HE ShanShan WANG Qiang ZHANG WenJun BI RuiYu CUI Juan ZHENG YongQiu XUE ChenYang | 2021 | Science China(Technological Sciences)2021，64，6： | 2 |
| 3 | Variational Gridded Graph Convolution Network for Node Classification显示文摘The existing graph convolution methods usually suffer high computational burdens,large memory requirements,and intractable batch-processing.In this paper,we propose a high-efficient variational gridded graph convolution network(VG-GCN)to encode non-regular graph data,which overcomes all these aforementioned problems.To capture graph topology structures efficiently,in the proposed framework,we propose a hierarchically-coarsened random walk(hcr-walk)by taking advantage of the classic random walk and node/edge encapsulation.The hcr-walk greatly mitigates the problem of exponentially explosive sampling times which occur in the classic version,while preserving graph structures well.To efficiently encode local hcr-walk around one reference node,we project hcrwalk into an ordered space to form image-like grid data,which favors those conventional convolution networks.Instead of the direct 2-D convolution filtering,a variational convolution block(VCB)is designed to model the distribution of the randomsampling hcr-walk inspired by the well-formulated variational inference.We experimentally validate the efficiency and effectiveness of our proposed VG-GCN,which has high computation speed,and the comparable or even better performance when compared with baseline GCNs. | Xiaobin Hong Tong Zhang Zhen Cui Jian Yang | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，10： | 2 |

| 19 | Shipborne oceanic high-spectral-resolution lidar for accurate estimation of seawater depth-resolved optical properties显示文摘Lidar techniques present a distinctive ability to resolve vertical structure of optical properties within the upper water column at both day-and night-time.However,accuracy challenges remain for existing lidar instruments due to the ill-posed nature of elastic backscatter lidar retrievals and multiple scattering.Here we demonstrate the high performance of,to the best of our knowledge,the first shipborne oceanic high-spectral-resolution lidar(HSRL)and illustrate a multiple scattering correction algorithm to rigorously address the above challenges in estimating the depth-resolved diffuse attenuation coefficient Kd and the particulate backscattering coefficient bbp at 532 nm.HSRL data were collected during day-and night-time within the coastal areas of East China Sea and South China Sea,which are connected by the Taiwan Strait.Results include vertical profiles from open ocean waters to moderate turbid waters and first lidar continuous observation of diel vertical distribution of thin layers at a fixed station.The root-mean-square relative differences between the HSRL and coincident in situ measurements are 5.6%and 9.1%for Kd and bbp,respectively,corresponding to an improvement of 2.7-13.5 and 4.9-44.1 times,respectively,with respect to elastic backscatter lidar methods.Shipborne oceanic HSRLs with high performance are expected to be of paramount importance for the construction of 3D map of ocean ecosystem. | Yudi Zhou Yang Chen Hongkai Zhao Cedric Jamet Davide Dionisi Malik Chami Paolo Di Grolamo James H.Churnside Aleksey Malinka Huade Zhao Dajun Qiu Tingwei Cui Qun Liu Yatong Chen Sornsiri Phongphattarawat Nanchao Wang Sijie Chen Peng Chen Ziwei Yao Chengfeng Le Yuting Tao Peituo Xu Xiaobin Wang Binyu Wang Feitong Chen Chuang Ye Kai Zhang Chong Liu Dong Liu | 2022 | Light(Science & Applications)2022，11，10： | 0 |
| 20 | Magnetotelluric imaging and tectonic movement characteristics of the central Yunnan sub-block and its adjacent areas显示文摘The central Yunnan sub-block is an important channel for southeast migration of materials in the Qinghai-Xizang Plateau,and therefore a key area to study tectonic movement and deformation.In this study,a three-dimensional electrical structure of the crust and upper mantle lithosphere was derived from magnetotelluric data inversion along a survey line across the central Yunnan sub-block.Results suggest that the middle and upper crust of the central Yunnan sub-block is comprised of several independent high-resistivity bodies.Deep extension of some faults was revealed according to electrical structure and relocated microseismicity.The Chenghai fault extends downward along the eastern boundary of a high-resistivity body.The Yuanmou fault dips to the west and extends to the depth along the boundary between two high-resistivity bodies.The Tanglang-Yimen fault cuts through a high-resistivity body in the middle and upper crust.There is an obvious high-conductivity C1 layer in the lower crust in the eastern part of the central Yunnan sub-block,and its western border displays an obvious structural boundary in the shallow part.The eastern part of the central Yunnan sub-block moves eastward relative to the western part(bounded by the west side of a high-resistivity body R3 in the C1 west).C1 is speculated to be characterized by low rheological strength and viscosity,thus reducing the resistance to eastward movement of the eastern part.Owing to the combined action of C1 and its western boundary,the eastern materials slip eastward faster relative to R3.Due to South China Block resistance,the middle and upper crust in the eastern part is within a compressional tectonic environment,consistent with the negative dilatation rate and the presence of compressive faults in this region.The C1 ground surface has a low strain rate,indicating weak deformation in this region and rigid motion dominance.Our results suggest that under the decoupling effect of the high-conductivity layer in the lower crust,the independent rigid blocks in the middle and upper crust can also exhibit tectonic deformation characteristics of rigid extrusion. | Tengfa CUI Xiaobin CHEN | 2023 | Science China Earth Sciences2023，66，2： | 0 |
