| 1 | Advances in metal phosphides for sodium-ion batteries显示文摘Sodium-ion batteries(SIBs)have been extensively studied as the potential alter-native to lithium-ion batteries(LIBs)due to the abundant natural reserves and low price of sodium resources.Nevertheless,Na+ions possess a larger radius than Li+,resulting in slow diffusion dynamics in electrode materials,and thus seeking appropriate anode materials to meet high performance standards has become a trend in the field of SIBs.In this context,owing to the advantages of high theoretical capacity and proper redox potential,metal phosphides(MPs)are considered to be the promising materials to make up for the gap of SIBs anode materials.In this review,the recent development of MPs anode materials for SIBs is reviewed and analyzed comprehensively and deeply,including the synthesis method,advanced modification strategy,electrochemical performance,and Na storage mechanism.In addition,to promote the wide application of the emerg-ing MPs anodes for SIBs,several research emphases in the future are pointed out to overcome challenges toward the commercial application. | Qifei Li Dan Yang Haoliang Chen Xiang Lv Yu Jiang Yuezhan Feng Xianhong Rui Yan Yu | 2021 | SusMat2021，1，3： | 5 |
| 2 | Modeling grassland net primary productivity and water-use efficiency along an elevational gradient of the Northern Tianshan Mountains显示文摘Mountainous ecosystems are considered highly sensitive and vulnerable to natural disasters and climatic changes.Therefore,quantifying the effects of elevation on grassland productivity to understand ecosystem-climate interactions is vital for mountainous ecosystems.Water-use efficiency(WUE)provides a useful index for understanding the metabolism of terrestrial ecosystems as well as for evaluating the degradation of grasslands.This paper explored net primary productivity(NPP)and WUE in grasslands along an elevational gradient ranging from 400 to 3,400 m asl in the northern Tianshan Mountains-southern Junggar Basin(TMJB),Xinjiang of China,using the Biome-BGC model.The results showed that:1)the NPP increased by 0.05 g C/(m2·a)with every increase of 1-m elevation,reached the maximum at the mid-high elevation(1,600 m asl),and then decreased by 0.06 g C/(m2·a)per 1-m increase in elevation;2)the grassland NPP was positively correlated with temperature in alpine meadow(AM,2,700-3,500 m asl),mid-mountain forest meadow(MMFM,1,650-2,700 m asl)and low-mountain dry grassland(LMDG,650-1,650 m asl),while positive correlations were found between NPP and annual precipitation in plain desert grassland(PDG,lower than 650 m asl);3)an increase(from 0.08 to 1.09 g C/(m2·a))in mean NPP for the grassland in TMJB under a real climate change scenario was observed from 1959 to 2009;and 4)remarkable differences in WUE were found among different elevations.In general,WUE increased with decreasing elevation,because water availability is lower at lower elevations;however,at elevations lower than 540 m asl,we did observe a decreasing trend of WUE with decreasing elevation,which may be due to the sharp changes in canopy cover over this gradient.Our research suggests that the NPP simulated by Biome-BGC is consistent with field data,and the modeling provides an opportunity to further evaluate interactions between environmental factors and ecosystem productivity. | QiFei HAN GePing LUO ChaoFan LI Hui YE YaoLiang CHEN | 2013 | Journal of Arid Land2013，5，3： | 5 |
| 3 | A novel ball-in-ball hollow oxygen-incorporating cobalt sulfide spheres as high-efficient electrocatalyst for oxygen evolution reaction显示文摘Transition-metal chalcogenides with hollow nanostructure,especially cobalt sulfides,are considered as the most pro mising non-precious metal catalysts for oxygen evolution reactio n.However,it is difficult to synthesize oxygen-containing cobalt sulphides with hollow structure due to the different physical/chemical properties between metal sulfides and metal cobalts.Herein,we report a novel oxygencontaining amorphous cobalt sulfide ball-in-ball hollow sphere s(Co-S-O BBHS) synthesized by an anion exchange method.Taking advantage of the ball-in-ball hollow structure,the amorphous Co-S-O BBHS shows supe rior oxygen evolution reaction(OER) electrocatalytic performance with a low overpotentiat of285 mV at 10 mA/cm2,small Tafel slope of 49.67 mV/dec,high Faraday efficiency of 96%,and satisfied durability.Experiments and DFT calculations demonstrate that the introduction of oxygen and sulfur modulates the electronic structure of Co-S-O BBHS,thus enhancing the adsorption of *0(adsorbed 0 species on catalyst surface) intermediate,which greatly boosts the catalytic activity towards OER.This work provides a new strategy for controllable synthe sis of complex hollow structures of transition-metal chalcogenides for OER. | Yurong Li Qifei Guo Yimin Jiang Wei Shen Ming Li Rongxing He | 2021 | Chinese Chemical Letters2021，32，2： | 2 |
| 4 | A High-Capacity Ammonium Vanadate Cathode for Zinc-Ion Battery显示文摘Given the advantages of being abundant in resources,environmental benign and highly safe,rechargeable zinc-ion batteries(ZIBs)enter the global spotlight for their potential utilization in large-scale energy storage.Despite their preliminary success,zinc-ion storage that is able to deliver capacity>400 mAh g^-1 remains a great challenge.Here,we demonstrate the viability of NH4V4O10(NVO)as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity.The first-principles calculations reveal that layered NVO is a good host to provide fast Zn^2+ions diffusion channel along its[010]direction in the interlayer space.On the other hand,to further enhance Zn^2+ion intercalation kinetics and long-term cycling stability,a three-dimensional(3D)flower-like architecture that is self-assembled by NVO nanobelts(3D-NVO)is rationally designed and fabricated through a microwave-assisted hydrothermal method.As a result,such 3D-NVO cathode possesses high capacity(485 mAh g^-1)and superior long-term cycling performance(3000 times)at 10 A g^-1(~50 s to full discharge/charge).Additionally,based on the excellent 3D-NVO cathode,a quasi-solid-state ZIB with capacity of 378 mAh g^-1is developed. | Qifei Li Xianhong Rui Dong Chen Yuezhan Feng Ni Xiao Liyong Gan Qi Zhang Yan Yu Shaoming Huang | 2020 | Nano-Micro Letters2020，12，5： | 2 |
| 5 | 3D porous V2O5 architectures for high-rate lithium storage显示文摘The discovery of novel electrode materials promises to unleash a number of technological advances in lithium-ion batteries.V2O5 is recognized as a high-performance cathode that capitalizes on the rich redox chemistry of vanadium to store lithium.To unlock the full potential of V2O5,nanotechnology solution and rational electrode design are used to imbue V2O5 with high energy and power density by addressing some of their intrinsic disadvantages in macroscopic crystal form.Here,we demonstrate a facile and environmental-friendly method to prepare nanorods-constructed 3D porous V2O5 architectures(3 D-V2O5)in large-scale.The 3D porous architecture is found to be responsible for the enhanced charge transfer kinetics and Li-ion diffusion rate of the 3D-V2O5 electrode.As the result,the 3D-V2O5 surpasses the conventional bulk V2O5 by showing enhanced discharge capacity and rate capability(delivering 154 and 127 m Ah g^-1 at 15 and 20 C,respectively). | Qifei Li Dong Chen Huiteng Tana Xianghua Zhang Xianhong Rui Yan Yu | 2020 | Journal of Energy Chemistry2020，29，1： | 1 |
| 6 | Histology and antitumor activity study of PTX-loaded micelle,a fluorescent drug delivery system prepared by PEG-TPP显示文摘We synthesized PEG-TPP as carrier to encapsulate paclitaxel (PTX) in the form of micelles to overcome its water-solubility problem. PTX-loaded micelles possess a-week stability and appropriate particle size (152.1 ±1.2 nm) which is beneficial for enhanced permeability and retention (EPR) effect. Strong pH dependence of PTX releasing from micelles is verified by in vitro release study. At cellular level, PTX-loaded micelles can target mitochondria effectively which may results a better cytotoxicity of micelles (especially IC50 = 0.123 ± 0.035μmol/L of micelles and 0.298 ± 0.067μmol/L of PTX alone on MCF-7 cells). The fluorescence distributions of both isolated and sliced organs show that the micelles can effectively target tumors. Moreover, we further prove the enhanced therapeutic effects of micelles in tumor-bearing mice comparing with PTX alone. The results show that the biodegradable drug delivery system prepared by PEG-TPP can overcome the poor solubility of paclitaxel and improve its tumor targeting and antitumor activity. | Huilan Li Jieming Li Xinyi He Bo Zhang Chunxia Liu Qifei Li Ying Zhu Wenlong Huang Wei Zhang Hai Qian Liang Ge | 2019 | Chinese Chemical Letters2019，30，5： | 1 |
| 7 | RALF signaling pathway activates MLO calcium channels to maintain pollen tube integrity显示文摘Pollen tube tip growth requires intricate Ca^(2+)signaling.Recent studies have also identified rapid alkalization factor(RALF)-family peptides and their receptors as critical components for pollen tube tip growth and integrity.The functional relationship of RALF and calcium signaling modules remains largely unclear.Here we report that disruption of RALF signaling pathway abolished the cytosolic Ca^(2+)gradient in the pollen tube,indicating that Ca^(2+)signaling is downstream of the RALF signaling pathway.We identified MILDEW RESISTANCE LOCUS O(MLO)family proteins MLO1,5,9,15,as Ca^(2+)channels required for Ca^(2+)influx and pollen tube integrity.We further reconstituted the biochemical pathway in which signaling via RALF and RALF receptors activated MLO1/5/9/15 calcium channels.Together,we conclude that RALF peptides derived from pollen tube bind to their receptors to establish pollen tube Ca^(2+)gradient through activation of the MLO channels.Our finding has thus provided a mechanistic link between the RALF signaling pathway and Casignaling in controlling pollen tube integrity and growth.^(2+) | Qifei Gao Chao Wang Yasheng Xi Qiaolin Shao Congcong Hou Legong Li Sheng Luan | 2023 | Cell Research2023，33，1： | 1 |

| 10 | Highly oriented MAPbI3 crystals for efficient hole-conductor-free printable mesoscopic perovskite solar cells显示文摘Highly crystalline perovskite films with large grains and few grain boundaries are conducive for efficient and stable perovskite solar cells.Current methods for preparing perovskite films are mostly based on a fast crystallization process,with rapid nucleation and insufficient growth.In this study,MAPbI3 perovskite with inhibited nucleation and promoted growth in the TiO_(2)/ZrO_(2)/carbon triple mesoscopic scaffold was crystallized by modulating the precursor and the crystallization process.N-methylformamide showed high solubility for both methylammonium iodide and Pbl2 and hampered the formation of large colloids in the MAPbI3 precursor solution.Furthermore,methylammonium chloride was added to reduce large colloids,which are a possible source of nucleation sites.During the crystallization of MAPbI3,the solvent was removed at a slow controlled speed,to avoid rapid nucleation and provide sufficient time for crystal growth.As a result,highly oriented MAPbI3 crystals with suppressed non-radiative recombination and promoted charge transport were obtained in the triple mesoscopic layer with disordered pores.The corresponding hole-conductor-free,printable mesoscopic perovskite solar cells exhibited a highest power conversion efficiency of 18.82%.The device also exhibited promising long-term operational sta-bility of 1000 h under continuous illumination at maximum power point at 55±5°C and damp-heat stability of 1340 h aging at 85°C as well as 85%relative humidity. | Shuang Liu Deyi Zhang Yusong Sheng Weihua Zhang Zhaotong Qin Minchao Qin Sheng Li Yifan Wang Chenxu Gao Qifei Wang Yue Ming Chao Liu Kai Yang Qingyi Huang Jianhang Qi Qiaojiao Gao Kai Chen Yue Hu Yaoguang Rong Xinhui Lu Anyi Mei Hongwei Han | 2022 | Fundamental Research2022，2，2： | 1 |

| 15 | Adaptability of machine learning methods and hydrological models to discharge simulations in datasparse glaciated watersheds显示文摘The accurate simulation and prediction of runoff in alpine glaciated watersheds is of increasing importance for the comprehensive management and utilization of water resources.In this study,long shortterm memory(LSTM),a state-of-the-art artificial neural network algorithm,is applied to simulate the daily discharge of two data-sparse glaciated watersheds in the Tianshan Mountains in Central Asia.Two other classic machine learning methods,namely extreme gradient boosting(XGBoost)and support vector regression(SVR),along with a distributed hydrological model(Soil and Water Assessment Tool(SWAT)and an extended SWAT model(SWAT_Glacier)are also employed for comparison.This paper aims to provide an efficient and reliable method for simulating discharge in glaciated alpine regions that have insufficient observed meteorological data.The two typical basins in this study are the main tributaries(the Kumaric and Toxkan rivers)of the Aksu River in the south Tianshan Mountains,which are dominated by snow and glacier meltwater and precipitation.Our comparative analysis indicates that simulations from the LSTM shows the best agreement with the observations.The performance metrics Nash-Sutcliffe efficiency coefficient(NS)and correlation coefficient(R^(2))of LSTM are higher than 0.90 in both the training and testing periods in the Kumaric River Basin,and NS and R^(2) are also higher than 0.70 in the Toxkan River Basin.Compared to classic machine learning algorithms,LSTM shows significant advantages over most evaluating indices.XGBoost also has high NS value in the training period,but is prone to overfitting the discharge.Compared with the widely used hydrological models,LSTM has advantages in predicting accuracy,despite having fewer data inputs.Moreover,LSTM only requires meteorological data rather than physical characteristics of underlying data.As an extension of SWAT,the SWAT_Glacier model shows good adaptability in discharge simulation,outperforming the original SWAT model,but at the cost of increasing the complexity of the model.Compared with the oftentimes complex semi-distributed physical hydrological models,the LSTM method not only eliminates the tedious calibration process of hydrological parameters,but also significantly reduces the calculation time and costs.Overall,LSTM shows immense promise in dealing with scarce meteorological data in glaciated catchments. | JI Huiping CHEN Yaning FANG Gonghuan LI Zhi DUAN Weili ZHANG Qifei | 2021 | Journal of Arid Land2021，13，6： | 0 |

| 19 | Self-Assembled VS4 Hierarchitectures with Enhanced Capacity and Stability for Sodium Storage显示文摘Sodium-ion batteries(SIBs)have become an auspicious candidate for largescale energy storage by cause of low cost,natural abundance,and similar working principle with lithium-ion batteries(LIBs).At present,there is an urgent need to explore superior anode materials with rapid and stable sodiation/desodiation.Herein,3D self-assembled VS4 curly nanosheets hierarchitectures(VS4-CN-Hs)are developed for SIB anodes,where VS4 possesses a large theoretical sodium storage capacity,and the building block of nanosheets has large exposed surface area to the electrolyte as well as the constructed hierarchitectures can provide abundant buffer space to alleviate the volume expansion.As a result,VS4-CN-Hs anode possesses excellent electrochemical performance under a wide voltage window of 0.01–3.0 V,such as high reversible capacity of 863 mA h g^(−1) at 0.1 A g^(−1),marvelous rate feature(444 mA h g^(−1) at 10 A g^(−1)),and extralong cycle stability(386 mA h g^(−1) after 1000 times at 5 A g^(−1)). | Siling Cheng Kaitong Yao Kunxiong Zheng Qifei Li Dong Chen Yu Jiang Weiling Liu Yuezhan Feng Xianhong Rui Yan Yu | 2022 | Energy & Environmental Materials2022，5，2： | 0 |
| 20 | Effects of Alkaline Treatment on Mechanical Properties of Straw Fiber-reinforced Cement Board显示文摘Straw fiber-reinforced cement board made from straw fiber and cement was prepared by semi-dry processing technology to investigate the effects of alkali treatment on the mechanical properties of the board.The results indicate that the board fibers were treated with 1%alkali solution showed obvious improvements in mechanical properties.After alkali treatment,hemi-celluloses of straw fiber were hydrolyzed and dissolved,which avoided hemi-celluloses hydrolyzing into monosaccharide to hinder the solidifying of cement. The fibers surface became rough,which increased the mechanical interweaving force between cement and fibers.Thereby the board’s mechanical properties were improved.At the same time,the increase of tensile strength and aspect ratio of the fibers improved the mechanical properties. | Ling Qifei Zheng Xia Li Xingong | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
