| 1 | Ni(OH)_(2) nanoparticles encapsulated in conductive nanowire array for high-performance alkaline seawater oxidation显示文摘Design and development of high-efficiency and durable oxygen evolution reaction(OER)electrocatalysts is crucial for hydrogen production from seawater splitting.Herein,we report the in situ electrochemical conversion of a nanoarray of Ni(TCNQ)2(TCNQ=tetracyanoquinodimethane)on graphite paper into Ni(OH)_(2) nanoparticles confined in a conductive TCNQ nanoarray(Ni(OH)_(2)-TCNQ/GP)by anode oxidation.The Ni(OH)_(2)-TCNQ/GP exhibits high OER performance and demands overpotentials of 340 and 382 mV to deliver 100 mA·cm^(−2) in alkaline freshwater and alkaline seawater,respectively.Meanwhile,the Ni(OH)_(2)-TCNQ/GP also demonstrates steady long-term electrochemical durability for at least 80 h under alkaline seawater. | Longcheng Zhang Jiaqian Wang Pengyu Liu Jie Liang Yongsong Luo Guanwei Cui Bo Tang Qian Liu Xuedong Yan Haigang Hao Meiling Liu Rui Gao Xuping Sun | 2022 | Nano Research2022，15，7： | 5 |
| 2 | Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community. | Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao | 2022 | Molecular Plant2022，15，3： | 4 |
| 3 | Genetic Analysis and Mapping of the Purple Gene in Purple Heading Chinese Cabbage显示文摘To analyze genetic linkage and map purple gene(Br Pur) controlling purple inner leaves trait of Chinese cabbage, a F2 population was constructed by selfing a F1 plant from homozygous purple heading line ‘14S839' and homozygous orange heading line ‘14S162'. The phenotype investigation of head color showed that the segregation ratio of purple to non-purple individuals was consistent with the expected ratio of 3:1,which indicated that purple inner leaves trait is controlled by a single dominant gene. A total of 297 SSRs in whole genome of Chinese cabbage were tested by modified Bulked Segregant Analysis(BSA) method. Two linked markers flanking Br Pur, A710 and A714, were obtained and Br Pur was mapped on linkage group A07 based on the sequence of these two markers. Subsequently, two new markers flanking Br Pur, CL-12 and B214-87, were developed based on two known anthocyanins-related genes, Br4CL3 and Bra004214. Genetic mapping of all markers in the F2 mapping population showed CL-12 and B214-87 linked to Br Pur with the genetic distance of 3.1 c M and 3.5 c M, respectively. | WU Junqing ZHAO Jing QIN Meiling REN Yanjing ZHANG Huamin DAI Zihui HAO Lingyu ZHANG Lugang | 2016 | Horticultural Plant Journal2016，2，6： | 3 |
| 4 | IncR26319/miR-2834/EndophilinA axis regulates oogenesis of the silkworm,Bombyx mori显示文摘Oocyte maturation is critical for insect reproduction.Vitellogenesis,the timely production and uptake of vitellogenin(Vg),is crucial for female fecundity.Vg is synthesized in fat body and absorbed by the oocytes through endocytosis during insect oogenesis.In the silkworm,Bombyx mori,we discovered that a nucleus-enriched long-noncoding RNA(lncRNA)lncR26319 regulates Endophilin A(EndoA)-a member of the endophilin family of endocytic proteins-through competitive binding to miR-2834.The lncR26319-miR-2834-EndoA axis was required for Vg endocytosis in the silkworm;loss of EndoA or overexpression ofmiR-2834significantlyreduced eggnumbers invirginmoths.Inaddition,accumulation of miR-2834 resulted in pupal and adult deformation and reduced fecundity in females.The expression of Vg,30-kDa(30K)protein,and egg-specific protein(Esp)decreased after knockdown of EndoA or overexpression of miR-2834,while knockdown of miR-2834 had an opposite effect on the expression of Vg,30K protein gene,and Esp.These results suggest that the lncR26319-miR-2834-EndoA axis contributes to the endocytic activity in theVguptake and leads to the normal progression of oogenesis in the silkworm.Thus,miR-2834 and EndoA are crucial for female reproduction and could be potential targets for new pest management strategies in lepidopterans. | Yi Wang Yu Fu Hao Chena Chenyue Zhao Qunxia Huang Meiling Chang Wujie Qiu Yawen Shen Dandan Li | 2023 | Insect Science2023，30，1： | 1 |
| 5 | Electrochemically prepared coniferous leaf-like nickel black membrane for desalination by solar-thermal energy conversion显示文摘The structures of the solar-thermal membranes always influence the performance of light absorption and salt resistance in desalination.Inspired by the hierarchical structure of the coniferous leaves with excellent sunlight absorption in frigid regions,a coniferous leaf-like nickel black(L-Ni)membrane for desalination by solar-thermal energy conversion was prepared through electroplating method under a constant voltage.The light trapping effect of coniferous leaf-like structure led to the light absorption enhanced to 92%,the evaporation rate improved to 1.38 kg·m^(-2)·h^(-1),and the solar-vapor conversion efficiency of L-Ni membrane reaching up to 89.75%under 1 sun irradiation.The stability of the membrane was still excellent after 20 cycles desalination because the coniferous leaf-like structure could enhance the hydrophobicity(water contact angle:152°)of the L-Ni membrane,and it was beneficial to salt resistance.The promising performance of L-Ni membrane with coniferous leaf-like structure provides a possibility to replace the noble metal solar-thermal conversion materials. | Dongmin Yue Bingbing Li De Sun Hao Zhang Meiling Liu Jingtong Yu | 2023 | Nano Research2023，16，7： | 1 |
| 6 | Suppression of PFKFB3-driven glycolysis restrains endothelial-to-mesenchymal transition and fibrotic response显示文摘Endothelial-to-mesenchymal transition(EndoMT),the process wherein endothelial cells lose endothelial identity and adopt mesenchymal-like phenotypes,constitutes a critical contributor to cardiac fibrosis.The phenotypic plasticity of endothelial cells can be intricately shaped by alteration of metabolic pathways,but how endothelial cells adjust cellular metabolism to drive EndoMT is incompletely understood.Here,we identified 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3(PFKFB3)as a critical driver of EndoMT via triggering abnormal glycolysis and compromising mitochondrial respiration.Pharmacological suppression of PFKFB3 with salvianolic acid C(SAC),a phenolic compound derived from Salvia miltiorrhiza,attenuates EndoMT and fibrotic response.PFKFB3-haplodeficiency recapitulates the anti-EndoMT effect of SAC while PFKFB3-overexpression augments the magnitude of EndoMT and exacerbates cardiac fibrosis.Mechanistically,PFKFB3-driven glycolysis compromises cytoplasmic nicotinamide adenine dinucleotide phosphate(reduced form,NADPH)production via hijacking glucose flux from pentose phosphate pathway.Efflux of mitochondrial NADPH through isocitrate/α-ketoglutarate shuttle replenishes cytoplasmic NADPH pool but meanwhile impairs mitochondrial respiration by hampering mitochondrial iron-sulfur cluster biosynthesis.SAC disrupts PFKFB3 stability by accelerating its degradation and thus maintains metabolic homeostasis in endothelial cells,underlying its anti-EndoMT effects.These findings for the first time identify the critical role of PFKFB3 in triggering EndoMT by driving abnormal glycolysis in endothelial cells,and also highlight the therapeutic potential for pharmacological intervention of PFKFB3(with SAC or other PFKFB3 inhibitors)to combat EndoMT-associated fibrotic responses via metabolic regulation. | Hao Zeng Ting Pan Meiling Zhan Renaguli Hailiwu Baolin Liu Hua Yang Ping Li | 2022 | Signal Transduction and Targeted Therapy2022，7，10： | 1 |

| 8 | High coercivity Nd-Ce-Fe-B nanostructured ribbons prepared from melt spinning technique显示文摘The Ce-substituted(Nd1-xCex)12.2 Fe81.6 B6.2(x=0.0, 0.2, 0.4, 0.6) nanocrystalline ribbons were prepared by annealing amorphous ribbons from melt spinning. It is found that all ribbons are in a multiphase state consisting of a-Fe phase, Nd(Ce)-rich phases and RE2 Fe14 B(RE = Nd, Ce) phases. However, the coercivity of all annealed ribbons can reach a considerably high value without doping any heavy rare earth or other coercivity enhanced elements. A strong intergranular exchange coupling appears in these nanocrystalline ribbons. The Nd12.2 Fe81.6 B6.2 ribbons with multiphase have a coercivity of about 11.3 k Oe, and the coercivity decreases slightly with increasing Ce content. A coercivity of 7.5 kOe can be obtained when60 at% of Nd is replaced by Ce(x = 0.6) due to the grain refinement and the strong intergranular exchange coupling. This provides a practical approach of fabricating high coercivity Ce-substituted Nd-Fe-B materials. | Liang Zha Zhou Liu Hao Chen Mingzhu Xue Guanyi Qiao Shilei Ding Xin Wen Meiling Zhang Youfang Lai Wenyun Yang Jingzhi Han Dong Zhou Chenyao Zhu Jinbo Yang | 2019 | Journal of Rare Earths2019，37，10： | 1 |
| 9 | Model-free feature screening for high-dimensional survival data显示文摘With the rapid-growth-in-size scientific data in various disciplines, feature screening plays an important role to reduce the high-dimensionality to a moderate scale in many scientific fields. In this paper, we introduce a unified and robust model-free feature screening approach for high-dimensional survival data with censoring, which has several advantages: it is a model-free approach under a general model framework, and hence avoids the complication to specify an actual model form with huge number of candidate variables; under mild conditions without requiring the existence of any moment of the response, it enjoys the ranking consistency and sure screening properties in ultra-high dimension. In particular, we impose a conditional independence assumption of the response and the censoring variable given each covariate, instead of assuming the censoring variable is independent of the response and the covariates. Moreover, we also propose a more robust variant to the new procedure, which possesses desirable theoretical properties without any finite moment condition of the predictors and the response. The computation of the newly proposed methods does not require any complicated numerical optimization and it is fast and easy to implement. Extensive numerical studies demonstrate that the proposed methods perform competitively for various configurations. Application is illustrated with an analysis of a genetic data set. | Yuanyuan Lin Xianhui Liu Meiling Hao | 2018 | Science China Mathematics2018，61，9： | 1 |
| 10 | Atomically dispersed Fe sites on hierarchically porous carbon nanoplates for oxygen reduction reaction显示文摘Developing cost-effective,robust and stable non-precious metal catalysts for oxygen reduction reaction(ORR) is of paramount importance for electrochemical energy conversion devices such as fuel cells and metal-air batteries.Although Fe-N-C single atom catalysts(SACs) have been hailed as the most promising candidate due to the optimal binding strength of ORR intermediates on the Fe-N_(4) sites,they suffer from serious mass transport limitations as microporous templates/substrates,i.e.,zeolitic imidazolate frameworks(ZIFs),are usually employed to host the active sites.Motivated by this challenge,we herein develop a hydrogen-bonded organic framework(HOF)-assisted pyrolysis strategy to construct hierarchical micro/mesoporous carbon nanoplates for the deposition of atomically dispersed Fe-N_(4) sites.Such a design is accomplished by employing HOF nanoplates assembled from 2-aminoterephthalic acid(NH_(2)-BDC) and p-phenylenediamine(PDA) as both soft templates and C,N precursors.Benefitting from the structural merits inherited from HOF templates,the optimized catalyst(denoted as Fe-N-C SAC-950) displays outstanding ORR activity with a high half-wave potential of 0.895 V(vs.reversible hydrogen electrode(RHE)) and a small overpotential of 356 mV at 10 mA cm^(-2) for the oxygen evolution reaction(OER).More excitingly,its application potential is further verified by delivering superb rechargeability and cycling stability with a nearly unfading charge-discharge gap of 0.72 V after 160 h.Molecular dynamics(MD) simulations reveal that micro/mesoporous structure is conducive to the rapid mass transfer of O_(2),thus enhancing the ORR performance.In situ Raman results further indicate that the conversion of O_(2) to~*O_(2)-the rate-determining step(RDS) for Fe-N-C SAC-950.This work will provide a versatile strategy to construct single atom catalysts with desirable catalytic properties. | Ruixue Zheng Qinglei Meng Hao Zhang Teng Li Di Yang Li Zhang Xiaolong Jia Changpeng Liu Jianbing Zhu Xiaozheng Duan Meiling Xiao Wei Xing | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |
| 11 | KIF3C Promotes the Malignant Progression of Lung Cancer Cells A549显示文摘Objective:To investigate the role of KIF3C gene in promoting the malignant phenotype of lung cancer cells and in regulating PI3K/AKT signaling pathway.Methods:CCK-8 and transwell assays were used to detect the changes in cell proliferation and cell migration ability after being transfected with siKIF3C,as well as the protein expression levels of PI3K,p-PI3K,AKT,and p-AKT following the downregulation of KIF3C by Western blot.Results:The CCK-8 assay showed that the proliferation/viability of lung cancer cells A549 significantly reduced after being transfected with siKIF3C gene(P<0.05);the migration ability of lung cancer cells A549 was significantly reduced after transfected with siKIF3C gene(P<0.05);the levels of p-PI3K and p-AKT proteins were downregulated after KIF3C protein knockdown(P<0.05);however,the detection of PI3K and AKT protein levels was not statistically significant.Conclusion:KIF3C may promote the proliferation and migration ability of lung cancer cells A549 through PI3K/AKT signaling pathway. | Haiwang Liu Ran Liu Meiling Hao Xing Zhao Chunhui Li | 2022 | Proceedings of Anticancer Research2022，6，6： | 0 |
| 12 | CT and multimodal imaging findings of primary orbital Ewing's sarcoma involving the middle cranial fossa: a case report显示文摘This report details the CT and MR imaging findings of a primary orbital Ewing's sarcoma case involving the middle cranial fossa in a 13-year old boy.CT showed an ill-circumscribed homogeneous soft-tissue density mass with needle-like bone reaction.On MRI,the mass showed homogeneous iso-intensity on T1WI,heterogeneous hyperintensity on T2WI,and marked homogeneous enhancement.Meanwhile,the mass was hyper-intense on DWI,and ADC value was 575×10^(-6) mm^2/s.The mass showed as high rCBV and rCBF,prolonged MTT based on DCSPWI,and wash-out pattern of TIC derived from the DCE-MRI.Our case suggests that functional MRI modalities,including DWI,DSC-PWI or DCE-MR,could provide additional information for differential diagnoses.Both CT and MRI should be performed and comprehensively analyzed for limiting differential diagnoses,determining lesion extension and facilitating operative approach. | Xiaoquan Xu Feiyun Wu Yunxiang Chen Hao Hu Meiling Bao | 2017 | The Journal of Biomedical Research2017，31，2： | 0 |
| 13 | The SmNPR4-SmTGA5 module regulates SA-mediated phenolic acid biosynthesis in Salvia miltiorrhiza hairy roots显示文摘Phenolic acids are the main bioactive compounds in Salvia miltiorrhiza,which can be increased by salicylic acid(SA)elicitation.However,the specific molecular mechanism remains unclear.The nonexpresser of PR genes 1(NPR1)and its family members are essential components of the SA signaling pathway.Here,we report an NPR protein,SmNPR4,that showed strong expression in hairy root after SA treatment,acting as a negative moderator of SA-induced phenolic acid biosynthesis in S.miltiorrhiza(S.miltiorrhiza).Moreover,a basic leucine zipper family transcription factor SmTGA5 was identified and was found to interact with SmNPR4.SmTGA5 activates the expression of phenolic acid biosynthesis gene SmTAT1 through binding to the as-1 element.Finally,a series of biochemical assays and dual gene overexpression analysis demonstrated that the SmNPR4 significantly inhibited the function of SmTGA5,and SA can alleviate the inhibitory effect of SmNPR4 on SmTGA5.Overall,our results reveal the molecular mechanism of salicylic acid regulating phenolic acid biosynthesis in S.miltiorrhiza and provide new insights for SA signaling to regulate secondary metabolic biosynthesis. | Meiling Ding Bin Zhang Shuo Zhang RongRong Hao Yu Xia Pengda Ma Juane Dong | 2023 | Horticulture Research2023，10，5： | 0 |
| 14 | Synthesis ofα-Li FeO_(2)/Graphene nanocomposite via layer by layer self-assembly strategy for lithium-ion batteries with excellent electrochemical performance显示文摘As a potential alternative cathode material,α-LiFeO2 suffers a realization handicap,mainly due to its poor electrical conductivity and low lithium ion diffusion rate.In this work,we have successfully synthesized α-LiFeO2/rGO nanocomposite through a layer by layer self-assembly modification process and annealing treatment.Due to the strong electrostatic attraction between opposite cha rged spices,α-LiFeO2 nanoparticles were homogeneously dispersed on the graphene sheet to form a typical interconnected conducting network which was bene ficial for electronic conductivity and ionic diffu sivity.In comparison to pristine α-LiFeO2,the α-LiFeO2/rGO displayed an excellent electrochemical perfo rmance with average discharge capacities of 238.9,187.2,178.4,121.8 and 99.5 mA hg^-1 at 0.1,0.2,0.5,1 and 2 C,respectively.Besides,the specific capacity retained 164.9 mA h g^-1 and 107.98 mA h g^-1 after 50 cycles at 0.5 C and 1 C,respectively.The remarkable progress in rate capability and cycling ability of this new nanocomposite developed a new approach to improve the electrochemical performance of α-LiFeO2. | Youzuo Hu Hongyuan Zhao Ming Tan Jintao Liu Xiaohui Shu Meiling Zhang Shanshan Liu Qiwen Ran Hao Li Xingquan Liu | 2020 | Journal of Materials Science & Technology2020，52，20： | 0 |
| 15 | Knockdown of KIF3C Inhibits Epithelial-Mesenchymal Transition in Lung Cancer Cells A549显示文摘The objective of this study is to reveal the role of KIF3C gene in the proliferation of lung cancer cells,and the regulation of epithelial mesenchymal transition(EMT)of tumor cells.The plate clone formation assay and cell scratch assay were used in this study to detect the changes of cell proliferation and migration ability after siKIF3C interference,while EMT-related protein expression after KIF3C downregulation was detected by Western blot.The cell clone formation assay showed that the number of clones of lung cancer cells A549 was significantly reduced after transfected with siKIF3C(P<0.05);The scratch assay showed that the healing ability of cells was significantly reduced after transfected with siKIF3C(P<0.05);Western blot protein analysis revealed that the levels of EMT-related proteins,N-cadherin,Vimentin,Snail,and Slug were significantly down-regulated(P<0.05),however,E-cadherin protein levels were up-regulated after siKIF3C interference.In conclusion,KIF3C may promote the proliferation and invasive ability of lung cancer cells A549 through EMT. | Haiwang Liu Ran Liu Meiling Hao Xing Zhao Chunhui Li | 2022 | Journal of Clinical and Nursing Research2022，6，5： | 0 |
| 16 | Effects of thickness on the microstructure and energy-storage performance of PLZT antiferroelectric thick films显示文摘The typical antiferroelectric(AFE)thick films Pb_(0.94)La_(0.04)(Zr_(0.98)Ti_(0.02))O_(3)(PLZT 4/98/2)with different thicknesses of 2,4,6 and 10μm were successfully deposited on Pt(111)/TiO_(2)/SiO_(2)/Si(100)substrates from polyvinylpyrrolidone(PVP)-modified chemical solution.The effects of thickness on the crystalline structure,electrical properties and the energy-storage performance were investigated in detail.X-Ray diffraction analysis and scanning electron microscopy pictures indicated that AFE films with a thickness less than 4m showed a(111)-preferred orientation with uniform surface microstructure.The electrical measurement results illustrated that,as the thickness increased,the saturation polarization,remnant polarization,dielectric constant and leakage current of AFE thick films were enhanced gradually,while the capacitive density and the critical breakdown fields were decreased.Moreover,all the PLZT 4/98/2 AFE films shared the same Curie temperature of about 224℃.As a result,the AFE thick films showed good energy-storage stability in a wide temperature range.The maximum energy-storage density of 47.4 J/cm^(3) was obtained in the 2-μm-thick PLZT 4/98/2 films measured at 3699 kV/cm. | Ningning Sun Ying Wang Liwen Zhang Xuefeng Zhang Xihong Hao Meiling Li | 2013 | Journal of Advanced Dielectrics2013，3，3： | 0 |
| 17 | Advanced preparation and application of bimetallic materials in lithium-sulfur batteries:A review显示文摘Lithium-sulfur(Li-S)batteries are considered highly promising as next-generation energy storage systems due to high theoretical capacity(2600 Wh kg^(-1))and energy density(1675 mA h g^(-1))as well as the abundant natural reserves,low cost of elemental sulfur,and environmentally friendly properties.However,several challenges impede its commercialization including low conductivity of sulfur itself,the severe“shuttle effect”caused by lithium polysulfides(LiPSs)during charge–discharge processes,volume expansion effects and sluggish reaction kinetics.As a solution,polar metal particles and their compounds have been introduced as the main hosts for sulfur cathode due to their robust catalytic activity and adsorption capability,effectively suppressing the“shuttle effect”of Li PSs.Bimetallic alloys and their compounds with multi-functional properties exhibit remarkable electrochemical performance more readily when compared to single-metal materials.Well-designed bimetallic materials demonstrate larger specific surface areas and richer active sites,enabling simultaneous high adsorption capability and strong catalytic properties.The synergistic effect of the“adsorption-catalysis”sites accelerates the adsorptiondiffusion-conversion process of Li PSs,ultimately achieving a long-lasting Li-S battery.Herein,the latest progress and performance of bimetallic materials in cathodes,separators,and interlayers of Li-S batteries are systematically reviewed.Firstly,the principles and challenges of Li-S batteries are briefly analyzed.Then,various mechanisms for suppressing“shuttle effects”of Li PSs are emphasized at the microscale.Subsequently,the performance parameters of various bimetallic materials are comprehensively summarized,and some improvement strategies are proposed based on these findings.Finally,the future prospects of bimetallic materials are discussed,with the hope of providing profound insights for the rational design and manufacturing of high-performance bimetallic materials for LSBs. | Yongbing Jin Nanping Deng Yanan Li Hao Wang Meiling Zhang Weimin Kang Bowen Cheng | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
| 18 | Distribution Characteristics and Health Risk Assessment of Antimony in Atmospheric Particulates in a Northern City of China显示文摘Over the last several decades,scientists have established a wealth of evidence to demonstrate the risks posed to human health by toxic elements in atmospheric particulate matter(PM).Antimony(Sb),as one of ever ignored PM-bound heavy metals,attracts more and more attentions and has been regarded as one emerging air pollutant with the change of pollution sources of particulate matter.To study the distribution of Sb in PM with different particle sizes is of great practical significance for understanding its source and health risks.In this study,the size distributions of Sb in PM(PM_(2.5),PM_(10)and TSP)in different seasons were studied from July 2018 to May 2019.The high concentration of PM-bound Sb was found and the health risk was evaluated.Sb was enriched in fine particles and showed higher values in winter,which was probably caused by coal combustion and meteorological conditions.It was also found that traffic-related non-exhaust emissions might become another main contribution to fine particle Sb.Health risk assessment demonstrated that the hazard quotient(HQ)of Sb in PM_(2.5)and PM_(10)for children(PM_(2.5):1.54,PM_(10):1.32)exceeded the acceptable threshold and ingestion contributed the most to the HQ for both children and adults. | SHEN Yiwen ZHAO Hao ZHAO Changxian DONG Shuofei CAO Yuanming XIE Jiaojao LYU Meiling YUAN Chungang | 2023 | Chemical Research in Chinese Universities2023，39，3： | 0 |
| 19 | Multi-functional layered double hydroxides supported by nanoporous gold toward overall hydrazine splitting显示文摘Layered double hydroxides have demonstrated great potential for the oxygen evolution reaction,which is a crucial half-reaction of overall water splitting.However,it remains challenging to apply layered double hydroxides in other electrochemical reactions with high efficiency and stability.Herein,we report two-dimensional multifunctional layered double hydroxides derived from metalorganic framework sheet precursors supported by nanoporous gold with high porosity,which exhibit appealing performances toward oxygen/hydrogen evolution reactions,hydrazine oxidation reaction,and overall hydrazine splitting.The as-prepared catalyst only requires an overpotential of 233 mV to reach 10 mA·cm^(-2) toward oxygen evolution reaction.The overall hydrazine splitting cell only needs a cell voltage of 0.984 V to deliver 10 mA·cm^(-2),which is far more superior than that of the overall water splitting system(1.849 V).The appealing performances of the catalyst can be contributed to the synergistic effect between the metal components of the layered double hydroxides and the supporting effect of the nanoporous gold substrate,which could endow the sample with high surface area and excellent conductivity,resulting in superior activity and stability. | Yongji Qin Huijie Cao Qian Liu Shaoqing Yang Xincai Feng Hao Wang Meiling Lian Dongxing Zhang Hua Wang Jun Luo Xijun Liu | 2024 | Frontiers of Chemical Science and Engineering2024，18，1： | 0 |
| 20 | Effects of multi-sequence combination forces on creep characteristics of bales during wheat harvesting显示文摘During the baling operation,the wheat stalks are subjected to various mechanisms in the baler and the main form is compression.After the wheat stem is forced by a combination of the threshing cylinder,it needs to be formed under the action of straw baler and meet transport requirements.This paper mainly studies the properties of wheat stalks when baling,and proposes the application of the creep after-effect theory during the baling process.The tension-compression tester was used to perform a 50 mm stalk mechanical test,50 mm stalk static pressure test,35 mm×40 mm×50 mm stalk module static pressure test and bale static pressure test.The measured elastic modulus of the stem sample was 7.59 MPa,and the elastic modulus of the inner core of the stem was 8.24 MPa.The return curve of the single stalk and the bale is consistent with the initial creep and steady-state creep in the creep after-effect theory.A logarithmic function was used for fitting of the first stage with coefficient of determination R2=0.8364,and a linear function was used for fitting of the second stage with coefficient of determination R2=0.9921.The high water content static pressure test suggests that the load in the loading direction is the coupled load of the working load of the hydraulic cylinder and the internal stress of the bale.When harvesting wheat stalks with high moisture content,the density parameter of the bale can be appropriately increased while the load parameter of the hydraulic cylinder can be considered unchanged or even reduced.The adjustment of density and load can still ensure the forming quality of the bale. | Zhong Tang Yaquan Liang Ben Zhang Meiling Wang Hao Zhang Yaoming Li | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 0 |
