1Soil salt leaching under different irrigation regimes: HYDRUS-1D modelling and analysis显示文摘Field irrigation experiments were conducted in the Hetao Irrigation District of Inner Mongolia,China,to study the effects of irrigation regimes on salt leaching in the soil profile.The data were used to calibrate and validate the HYDRUS-1D model.The results demonstrated that the model can accurately simulate the water and salt dynamics in the soil profile.The HYDRUS-1D model was then used to simulate 15 distinct irrigation scenarios.The results of the simulation indicated that irrigation amount did not have a significant effect on soil water storage but that increases in irrigation amount could accelerate salt leaching.However,when the irrigation amount was larger than 20 cm,the acceleration was not obvious.Compared with irrigating only once,intermittent irrigation had a better effect on increasing soil water storage and salt leaching,but excessive irrigation times and intervals did not improve salt leaching.In addition,we found that the irrigation regime of 20 cm,irrigated twice at 1-d intervals,might significantly increase salt leaching in the plough layer and decrease the risks of deep seepage and groundwater contamination.WenZhi ZENG Chi XU JingWei WU JieSheng HUANG 2014Journal of Arid Land2014,6,1:20

3In-situ incorporation of Copper (Ⅱ) porphyrin functionalized zirconium MOF and TiO2 for efficient photocatalytic CO2 reduction显示文摘As one of the highly effective methods to prepare catalysts for photocatalytic reduction of CO2 into valueadded chemicals,using metalloporphyrin as light-harvesting mixed ligand to modify metal-organic framework(MOF)is very valuable since it can greatly improve the prophyrin dispersibility and consequently inhibit its potential agglomeration.Herein,we employed a one-pot synthetic strategy to chemically immobilize Cu(II)tetra(4-carboxylphenyl)porphyrin(CuTCPP)into UiO-66 MOF structure through coordination mode.Meanwhile,in-situ growth of TiO2 nanoparticles onto the MOF is actualized with the generation of CuTCPP c UiO-66/TiO2(CTU/TiO2)composites.Under Xe lamp irradiation(λ>300 nm),the catalytic result presents that an optimal value of 31.32 μmol g^-1 h^-1 CO evolution amount,about 7 times higher than that of pure TiO2 was obtained through the photocatalysis.It is supposed owning to a consistent augment of light absorption derived from chemically implanted porphyrin derivative,which is simultaneously functioning with an efficacious separation of photo-induced carries given by the newly engendered composites between MOF and TiO2,an effective catalytic activity and approving recyclability of CTU/TiO2 can be achieved in the photocatalytic reduction of CO2 into CO.Lei Wang Pengxia Jin Shuhua Duan Houde She Jingwei Huang Qizhao Wang 2019Science Bulletin2019,64,13:16
4Characterstics of seasonal variations of leaf n-alkanesand n-alkenes in modern higher plants in Qingjiang, Hubei Province, China显示文摘On the basis of GC and GC-MS analyses, the seasonal variation of leaf lipids is observed in five plant species in Qingjiang in Hubei Province. The CPI values (carbon preference index) of n-alkanes decrease gradually from May to November, though the carbon number distributions and the predominant carbon number in an individual species keep unchanged. The declined CPI values might be caused by the leaf fading, which is further supported by a comparison of the defoliated leaves with the fresh leaves. This observation infers the CPI values of n-alkanes in Quaternary sediments can be used as a tool to index the humification, and thus the climatic and the environmental conditions. The plants analyzed here show a remarkable difference in n-alkanes abundance, suggesting their differential contribution to the n-alkanes identified in sediments. The abundance and the compound species of the n-alkenes detected in the plant leaves change greatly with the seasons due to the influence of temperature, with the least compounds being identified in August.CUI JingWei HUANG JunHua XIE ShuCheng 2008Chinese Science Bulletin2008,53,17:10
5Pantograph-catenary electrical contact system of high-speed railways:recent progress,challenges,and outlooks显示文摘As the unique power entrance,the pantograph-catenary electrical contact system maintains the efficiency and reliability of power transmission for the high-speed train.Along with the fast development of high-speed railways all over the world,some commercialized lines are built for covering the remote places under harsh environment,especially in China;these environmental elements including wind,sand,rain,thunder,ice and snow need to be considered during the design of the pantograph-catenary system.The pantograph-catenary system includes the pantograph,the contact wire and the interface—pantograph slide.As the key component,this pantograph slide plays a critical role in reliable power transmission under dynamic condition.The fundamental material characteristics of the pantograph slide and contact wire such as electrical conductivity,impact resistance,wear resistance,etc.,directly determine the sliding electrical contact performance of the pantograph-catenary system;meanwhile,different detection methods of the pantograph-catenary system are crucial for the reliability of service and maintenance.In addition,the challenges brought from extreme operational conditions are discussed,taking the Sichuan-Tibet Railway currently under construction as a special example with the high-altitude climate.The outlook for developing the ultra-high-speed train equipped with the novel pantograph-catenary system which can address the harsher operational environment is also involved.This paper has provided a comprehensive review of the high-speed railway pantograph-catenary systems,including its progress,challenges,outlooks in the history and future.Guangning Wu Keliang Dong Zhilei Xu Song Xiao Wenfu Wei Huan Chen Jie Li Zhanglin Huang Jingwei Li Guoqiang Gao Guozheng Kang Chuanjun Tu Xingyi Huang 2022Railway Engineering Science2022,30,4:5
6Cancer metabolism and tumor microenvironment:fostering each other?显示文摘The changes associated with malignancy are not only in cancer cells but also in environment in which cancer cells live.Metabolic reprogramming supports tumor cells’high demand of biogenesis for their rapid proliferation,and helps tumor cells to survive under certain genetic or environmental stresses.Emerging evidence suggests that metabolic alteration is ultimately and tightly associated with genetic changes,in particular the dysregulation of key oncogenic and tumor suppressive signaling pathways.Cancer cells activate HIF signaling even in the presence of oxygen and in the absence of growth factor stimulation.This cancer metabolic phenotype,described firstly by German physiologist Otto Warburg,ensures enhanced glycolytic metabolism for the biosynthesis of macromolecules.The conception of metabolite signaling,i.e.,metabolites are regulators of cell signaling,provides novel insights into how reactive oxygen species(ROS)and other metabolites deregulation may regulate redox homeostasis,epigenetics,and proliferation of cancer cells.Moreover,the unveiling of noncanonical functions of metabolic enzymes,such as the moonlighting functions of phosphoglycerate kinase 1(PGK1),reassures the importance of metabolism in cancer development.The metabolic,microRNAs,and ncRNAs alterations in cancer cells can be sorted and delivered either to intercellular matrix or to cancer adjacent cells to shape cancer microenvironment via media such as exosome.Among them,cancer microenvironmental cells are immune cells which exert profound effects on cancer cells.Understanding of all these processes is a prerequisite for the development of a more effective strategy to contain cancers.Yiyuan Yuan Huimin Li Wang Pu Leilei Chen Dong Guo Hongfei Jiang Bo He Siyuan Qin Kui Wang Na Li Jingwei Feng Jing Wen Shipeng Cheng Yaguang Zhang Weiwei Yang Dan Ye Zhimin Lu Canhua Huang Jun Mei Hua-Feng Zhang Ping Gao Peng Jiang Shicheng Su Bing Sun Shi-Min Zhao 2022Science China(Life Sciences)2022,65,2:5
7Construction of ternary CuO/CuFe_(2)O_(4)/g-C_(3)N_(4)composite and its enhanced photocatalytic degradation of tetracycline hydrochloride with persulfate under simulated sunlight显示文摘In this study,a graphitic carbon nitride(g-C_(3)N_(4))based ternary catalyst Cu O/Cu Fe_(2)O_(4)/gC_(3)N_(4)(CCCN)is successfully prepared thorough calcination method.After confirming the structure and composition of CCCN,the as-synthesized composites are utilized to activate persulfate(PS)for the degradation of organic contaminant.While using tetracycline hydrochloride(TC)as pollutant surrogate,the effects of initial p H,PS and catalyst concentration on the degradation rate are systematically studied.Under the optimized reaction condition,CCCN/PS is able to give 99%degradation extent and 74%chemical oxygen demand removal in assistance of simulated solar light,both of which are apparently greater than that of either Cu O/Cu Fe_(2)O_(4)and pristine g-C_(3)N_(4).The great improvement in degradation can be assignable to the effective separation of photoinduced carriers thanks to the integration between Cu O/Cu Fe_(2)O_(4)and g-C_(3)N_(4),as well as the increased reaction sites given by the g-C_(3)N_(4)substrate.Moreover,the scavenging trials imply that the major oxidative matters involved in the decomposition are hydroxyl radicals(·OH),superoxide radicals(·O_(2)^(-))and photo-induced holes(h^(+)).Lei Wang Xiaolei Ma Guofang Huang Rui Lian Jingwei Huang Houde She Qizhao Wang 2022Journal of Environmental Sciences2022,34,2:5
8Estimation of Sunflower Seed Yield Using Partial Least Squares Regression and Artificial Neural Network Models显示文摘Statistical models can efficiently establish the relationships between crop growth and environmental conditions while explicitly quantifying uncertainties. This study aimed to test the efficiency of statistical models established using partial least squares regression(PLSR) and artificial neural network(ANN) in predicting seed yields of sunflower(Helianthus annuus). Two-year field trial data on sunflower growth under different salinity levels and nitrogen(N) application rates in the Yichang Experimental Station in Hetao Irrigation District, Inner Mongolia, China, were used to calibrate and validate the statistical models. The variable importance in projection score was calculated in order to select the sensitive crop indices for seed yield prediction. We found that when the most sensitive indices were used as inputs for seed yield estimation, the PLSR could attain a comparable accuracy(root mean square error(RMSE) = 0.93 t ha-1, coefficient of determination(R^2) = 0.69) to that when using all measured indices(RMSE = 0.81 t ha-1,R^2= 0.77). The ANN model outperformed the PLSR for yield prediction with different combinations of inputs of both microplots and field data. The results indicated that sunflower seed yield could be reasonably estimated by using a small number of crop characteristic indices under complex environmental conditions and management options(e.g., saline soils and N application). Since leaf area index and plant height were found to be the most sensitive crop indices for sunflower seed yield prediction, remotely sensed data and the ANN model may be joined for regional crop yield simulation.ZENG Wenzhi XU Chi Gang ZHAO WU Jingwei HUANG Jiesheng 2018Pedosphere2018,28,5:4
9Sensitivity analysis of the SWAP(Soil-Water-Atmosphere-Plant)model under different nitrogen applications and root distributions in saline soils显示文摘Sensitivity analysis is important for determining the parameters in the model calibration process.In our study,a variance-based global sensitivity analysis(extended Fourier amplitude sensitivity test,EFAST)was applied to an agro-hydrological model(the SWAP(Soil-Water-Atmosphere-Plant model)model).The sensitivities of 20 parameters belonging to 4 categories(soil hydraulics,solute transport,root water uptake,and environmental stresses)for the simulated accumulated transpiration,dry matter(DM),and yield of sunflowers were analyzed under three nitrogen application rates(N1,N2,and N3),four salinity levels(S1,S2,S3,and S4),and three root distributions(R1,R2,and R3).The results indicated that for predominantly loamy soils,the high-impact parameters for accumulated transpiration,DM,and yield were the soil hydraulic parameters(αand n),critical stress index for compensatory root water uptake(ωc),the salt level at which salt stress starts(Pi),the decline of root water uptake above Pi(SSF),residual water content(θr),saturated water content(θs),and relative uptake of solutes by roots(TSCF).We also found that nitrogen application did not change the order of the parameter impacts on accumulated transpiration,DM,and yield.However,TSCF replacedαas the highest-impact parameter for the accumulated transpiration,DM,and yield at high salinity levels(S2 and S3).Furthermore,αwas also the highest-impact parameter for DM and yield under different root distributions,but the highest-impact parameters for transpiration wereωc,α,andθs under R1,R2,and R3,respectively.Nitrogen application could be neglected when considering the interactive effects of nitrogen application,salinity level,and root distribution on the transpiration,DM,and yield.Additionally,the mean values and uncertainties of the transpiration,DM,and yield were similar in all scenarios,except S3,which showed a sharp decrease in the mean values.We suggest determining the above eight parameters(α,n,ωc,Pi,SSF,θr,θs,and TSCF)and the saturated vertical hydraulic conductivity(Ks)based on rigorous calibrations with direct or indirect local measurements using economical methods(e.g.,a literature review),with limited observations for other parameters when using the SWAP model and other similar agro-hydrological models.Guoqing LEI Wenzhi ZENG Yonghua JIANG Chang AO Jingwei WU Jiesheng HUANG 2021Pedosphere2021,31,5:4
10Black phosphorus-based van der Waals heterostructures for mid-infrared light-emission applications显示文摘Mid-infrared(MIR)light-emitting devices play a key role in optical communications,thermal imaging,and material analysis applications.Two-dimensional(2D)materials offer a promising direction for next-generation MIR devices owing to their exotic optical properties,as well as the ultimate thickness limit.More importantly,van der Waals heterostructures-combining the best of various 2D materials at an artificial atomic level-provide many new possibilities for constructing MIR light-emitting devices of large tuneability and high integration.Here,we introduce a simple but novel van der Waals heterostructure for MIR light-emission applications built from thin-film BP and transition metal dichalcogenides(TMDCs),in which BP acts as an MIR light-emission layer.For BP–WSe_(2) heterostructures,an enhancement of~200% in the photoluminescence intensities in the MIR region is observed,demonstrating highly efficient energy transfer in this heterostructure with type-Ⅰ band alignment.For BP-MoS_(2) heterostructures,a room temperature MIR light-emitting diode(LED)is enabled through the formation of a vertical PN heterojunction at the interface.Our work reveals that the BP-TMDC heterostructure with efficient light emission in the MIR range,either optically or electrically activated,provides a promising platform for infrared light property studies and applications.Xinrong Zong Huamin Hu Gang Ouyang Jingwei Wang Run Shi Le Zhang Qingsheng Zeng Chao Zhu Shouheng Chen Chun Cheng Bing Wang Han Zhang Zheng Liu Wei Huang Taihong Wang Lin Wang Xiaolong Chen 2020Light(Science & Applications)2020,9,1:3
11Construction of TiO_(2)-covalent organic framework Z-Scheme hybrid through coordination bond for photocatalytic CO_(2) conversion显示文摘In this work,a covalent organic framework(COF),which is constructed by the building blocks of[5,10,15,20-tetrakis(4-aminophenyl)porphinato]copper(Ⅱ)(CuTAPP)and p-benzaldehyde,is employed to integrate with TiO_(2) for the purpose of establishing a Z-scheme hybrid.Within the system,isonicotinic acid performs the role of a bridge that connects the two components through a coordination bond.Further photocatalytic application reveals the hybrid framework is able to catalyze CO_(2) conversion under simulated solar light,resulting in CO production rate of 50.5 μmol g^(-1)·h^(-1),about 9.9 and 24.5 times that of COF and pristine TiO_(2),respectively.The ameliorated catalytic performance owes much to the por-phyrin block acting as photosensitizer that augments the light absorbance,and the establishment of Z-scheme system between the inorganic and orga nic comp on ents that enhances the separati on of the carriers.In addition,the chemical bridge also ensures a steady usage and stable charge delivery in the catalysis.Our study sheds light on the development of versatile approaches to covalently in corporate COFs with inorga nic semic on ductors.Lei Wang Guofang Huang Liang Zhang Rui Lian Jingwei Huang Houde She Chunli Liu Qizhao Wang 2022Journal of Energy Chemistry2022,31,1:3
12Cell wallβ-1,4-galactan regulated by the BPC1/BPC2-GALS1 module aggravates salt sensitivity in Arabidopsis thaliana显示文摘Salinity severely reduces plant growth and limits agricultural productivity.Dynamic changes and rearrangement of the plant cell wall is an important response to salt stress,but relatively little is known about the biological importance of specific cell wall components in the response.Here,we demonstrate a specific function ofβ-1,4-galactan in salt hypersensitivity.We found that salt stress induces the accumulation ofβ-1,4-galactan in root cell walls by up regulating the expression of GALACTAN SYNTHASE 1(GALS1),which encodes aβ-1,4-galactan synthase.The accumulation ofβ-1,4-galactan negatively affects salt tolerance.Exogenous application of D-galactose(D-Gal)causes an increase inβ-1,4-galactan levels in the wild type and GALS1 mutants,especially in GALS1 overexpressors,which correlated with the aggravated salt hypersensitivity.Furthermore,we discovered that the BARLEY B RECOMBINANT/BASIC PENTACYSTEINE transcription factors BPC1/BPC2 positively regulate plant salt tolerance by repressing GALS1 expression andβ-1,4-galactan accumulation.Genetic analysis suggested that GALS1 is genetically epistatic to BPC1/BPC2 with respect to the control of salt sensitivity as well as accumulation ofβ-1,4-galactan.Taken together,our results reveal a new regulatory mechanism by whichβ-1,4-galactan regulated by the BPC1/BPC2-GALS1 module aggravates salt sensitivity in Arabidopsis thaliana.Jingwei Yan Ya Liu Lan Yang Huan He Yun Huang Lin Fang Henrik Vibe Scheller Mingyi Jiang Aying Zhang 2021Molecular Plant2021,14,3:3
13Mechanical Properties of Sea Water Sea Sand Coral Concrete Modified with Different Cement and Fiber Types显示文摘The mechanical properties of modified sea water sea sand coral concrete(SWSSCC)under axial compression were experimentally studied.Two different parameters were considered in this test:types of cement and fiber.An experimental campaign was developed involving uniaxial compression tests and the use of digital image correlation(DIC)method to analyze the strain distribution and crack propagation of specimen.Test results indicated that the compressive strength and elastic modulus of SWSSCC were improved by adding stainless steel fibers(SSF),while polypropylene fibers(PF)enhanced the SWSSCC peak deformation.It was found that the elastic modulus and strength of SWSSCC using ordinary Portland cement(OPC)were higher compared to specimen with low alkalinity sulphoaluminate cement(LAS).Typical strain distribution changed with the variation of fiber types.The propagation and characteristics of cracks in SWSSCC containing PF were similar to those of cracks in SWSSCC.However,the propagation of cracks and the development of plastic deformation in SWSSCC were effectively hindered by adopting SSF.Finally,an analytical stress-strain expression of specimen considering the influences of fibers was established.The obtained results would provide a basis for the application of SWSSCC.Xibo Qi Yijie Huang Xiaowei Li Zhenhua Hu Jingwei Ying Dayong Li 2020Journal of Renewable Materials2020,8,8:2

15Research Progress of Ferrite Materials for Photoelectrochemical Water Splitting显示文摘Photoelectrochemical(PEC)water splitting is an effective strategy to convert solar energy into clean and renewable hydrogen energy.In order to carry out effective PEC conversion,researchers have conducted a lot of exploration and developed a variety of semiconductors suitable for PEC water splitting.Among them,metal oxides stand out due to their higher stability.Compared with traditional oxide semiconductors,ferrite-based photoelectrodes have the advantages of low cost,small band gap,and good stability.Interestingly,due to the unique characteristics of ferrite,most of them have various tunable features,which will be more conducive to the development of efficient PEC electrode.However,this complex metal oxide is also troubled by severe charge recombination and low carrier transport efficiency,resulting in lower conversion efficiency compared to theoretical value.Based on this,this article reviews the structure,preparation methods,characteristics and modification strategies of various common ferrites.In addition,we analyzed the future research direction of ferrite for PEC water splitting,and looked forward to the development of more efficient catalysts.Yani Wang Jingwei Huang Lei Wang Houde She Qizhao Wang 2022Chinese Journal of Structural Chemistry2022,41,1:2
16Experimental Investigation on Micro Deep Drawing of Stainless Steel Foils with Different Microstructural Characteristics显示文摘In the present work,austenitic stainless steel(ASS)304 foils with a thickness of 50μm were first annealed at temperatures ranging from 700 to 1100℃for 1 h to obtain different microstructural characteristics.Then the effects of microstructural characteristics on the formability of ASS 304 foils and the quality of drawn cups using micro deep drawing(MDD)were studied,and the mechanism involved was discussed.The results show that the as-received ASS 304 foil has a poor formability and cannot be used to form a cup using MDD.Serious wrinkling problem occurs on the drawn cup,and the height profile distribution on the mouth and the symmetry of the drawn cup is quite non-uniform when the annealing temperature is 700℃.At annealing temperatures of 900 and 950℃,the drawn cups are both characterized with very few wrinkles,and the distribution of height profile,symmetry and mouth thickness are uniform on the mouths of the drawn cups.The wrinkling becomes increasingly significant with a further increase of annealing temperature from 950 to 1100℃.The optimal annealing temperatures obtained in this study are 900 and 950℃for reducing the generation of wrinkling,and therefore improving the quality of drawn cups.With non-optimized microstructure,the distribution of the compressive stress in the circumferential direction of the drawn foils becomes inhomogeneous,which is thought to be the cause of the occurrence of localized deformation till wrinkling during MDD.Jingwei Zhao Tao Wang Fanghui Jia Zhou Li Cunlong Zhou Qingxue Huang Zhengyi Jiang 2021Chinese Journal of Mechanical Engineering2021,34,2:2

19Facile synthesis of Li2S@C composites as cathode for Li–S batteries显示文摘Lithium sulfide (Li2S) provides a promising route for lithium storage due to high theoretical specific capacity (1166 mAh g-1). The electrochemical performance of Li2S can be significantly enhanced by forming Li2S-carbon composites with the introduction of carbon. However, the complex synthesis method of Li2S-carbon composites restrains the large-scale productivity. Herein, we propose a facile route to prepare carbon coated Li2S-carbon nanotube composites (Li2S@C-CNT) via spray drying and heat treatment, which is a low-cost and large-scale method for facile synthesis of Li2S-carbon composites. For the Li2S@C-CNT composites, Li2S nanoparticles are contacted with surrounding particles due to the 3D CNTs framework. The novel construction not only suppresses the diffusion of polysulfides during cycling, but also remarkably accelerates the transport of electron and ion, resulting in a high specific capacity (1100 mAh g^-1) and good cycling performance. The rational designed architecture and good electrochemical performance of Li2S@C-CNT will pave the avenue for realizing high energy density of Li2S-based batteries.Xin Chen Linfeng Peng Lixia Yuan Rui Zeng Jingwei Xiang Weilun Chen Kai Yuan Jie Chen Yunhui Huang Jia Xie 2019Journal of Energy Chemistry2019,28,10:1
