| 1 | Impacts of revegetation management modes on soil properties and vegetation ecological restoration in degraded sandy grassland in farming-pastoral ecotone显示文摘Focusing on the impact of various vegetation management modes on sandy grassland's soil property and vegetation ecological restoration of farming-pastoral ecotone,field surveys and lab analysis were conducted to study the correlation between the characteristics of soil properties and vegetation ecological restoration under four different vegetation management modes,i.e.,unenclosed natural restoration,enclosed natural restoration,unenclosed artificial restoration and enclosed artificial restoration,which have a restoration history of 15 years in the southern edge of the degraded sandy land area of Mu Us Desert in Leilongwan Town,Hengshan County,Shaanxi Province.After 15 years of vegetation restoration,these four vegetation management modes all proved to be useful for improving the vegetation ecological restoration and the soil quality of the degraded sandy grassland not only by enhancing the aboveground vegetation height,coverage and biomass but also increasing the content of soil clay,organic matter,CEC,total nitrogen,available nutrient while reducing soil bulk density.The vegetation ecological restoration effect and soil quality under enclosed or artificial restoration management are better than those of unenclosed or natural restoration management;and the most satisfactory vegetation ecological restoration effects and soil quality can be achieved under the integration of enclosed and artificial restoration management.Severely degraded sandy grassland,during the vegetation restoration,would form an interactional coordinating relationship with the vegetation and soil properties.Vegetation properties as height,coverage and biomass have significant positive correlations with organic matter,CEC,total nitrogen and available nitrogen,phosphorus,and potassium contained in soil.Only the adoption of the strict enclosure system,implementation of aggressive artificial vegetation restoration measures and the realization of the regurgitation-feeding policy of industry towards husbandry can guarantee the gradual restoration of degraded sandy grassland in farming-pastoral ecotone,so that it can continue to play the role of ecological protective screen. | Fu Biao Qi Yanbing Chang Qingrui | 2015 | International Journal of Agricultural and Biological Engineering2015，8，1： | 10 |

| 3 | Pathological changes in the lungs and lymphatic organs of 12 COVID-19 autopsy cases显示文摘Systematic autopsy and comprehensive pathological analyses of COVID-19 decedents should provide insights into the disease characteristics and facilitate the development of novel therapeutics.In this study,we report the autopsy findings from the lungs and lymphatic organs of 12 COVID-19 decedents—findings that evaluated histopathological changes;immune cell signature and inflammatory factor expression in the lungs,spleen and lymph nodes.Here we show that the major pulmonary alterations included diffuse alveolar damage,interstitial fibrosis and exudative inflammation featured with extensive serous and fibrin exudates,macrophage infiltration and abundant production of inflammatory factors(IL-6,IP-10,TNFo?and IL-I f).The spleen and hilar lymph nodes contained lesions with tissue structure disruption and immune cell dysregulation,including lymphopenia and macrophage accumulation.These findings provide pathological evidence that links injuries of the lungs and lymphatic organs with the fatal systematic respiratory and immune malfunction in critically ill COVID-19 patients. | Qian Liu Yu Shi Jun Cai Yaqi Duan Rongshuai Wang Hongyan Zhang Qiurong Ruan Jiansha Li Lei Zhao Yifang Ping Rong Chen Liang Ren Xiaochun Fei Heng Zhang Rui Tang Xi Wang Tao Luo Xindong Liu Xuequan Huang Zhenhua Liu Qilin Ao Yong Ren Jing Xiong Zhicheng He Haibo Wu Wenjuan Fu Pengnan Zhao Xinwei Chen Guoqiang Qu Yunyun Wang Xi Wang Jia Liu Dongfang Xiang Sanpeng Xu Xiaowei Zhou Qingrui Li Jinghong Ma Heng Li Jie Zhang Sizhe Huang Xiaohong Yao Yiwu Zhou Chaofu Wang Dingyu Zhang Guoping Wang Liang Liu Xiu-Wu Bian | 2020 | National Science Review2020，7，12： | 6 |
| 4 | All-solid-state BiVO4/ZnIn2S4 Z-scheme composite with efficient charge separations for improved visible light photocatalytic organics degradation显示文摘Constructing a Z-scheme is a significant approach to improve the separation of photogene rated carriers for effective organic pollutant degradation.Herein,a BiVO4/ZnIn2S4(BZ) Z-scheme composite was successfully synthesized,and applied to photodegrade methyl orange(MO) irradiated by a LED lamp.Anchoring the BiVO4 on the ZnIn2S4 nanoparticles promoted the separation of photogenerated electronholes and broadened the light response range.The detailed characterizations,including surface morphology,elements valence state,and photocurrent performance,demonstrated that the enhanced separation of photogenerated carriers was the pivotal reason for the enhanced photocatalysis reaction.Benefiting from the excellent photocatalytic characteristics,the 5% mass ratio of BZ composite presented the highest MO degradation rate of 0.00997 min^-1,which was 1.9 and 10.3 times greater than the virgin ZnIn2S4 and BiVO4,respectively.Furthermore,the BZ hybrid materials indicated a well photo-stability in the four recycling tests. | Deling Yuan Mengting Sun Shoufeng Tang Yating Zhang Zetao Wang Jinbang Qi Yandi Rao Qingrui Zhang | 2020 | Chinese Chemical Letters2020，31，2： | 5 |
| 5 | Effects of Long-Term Fertilization on Soil Organic Carbon and Nitrogen in a Highland Agroecosystem显示文摘The effects of fertilization on the distributions of organic carbon(OC) and nitrogen(N) in soil aggregates and whether these effects vary with cropping system have not been well addressed.Such information is important for understanding the sequestration of OC and N in agricultural soils.In this study,the distributions of OC and N associated with soil aggregates were analyzed in different fertilization treatments in a continuous winter wheat cropping system and a legume-grain rotation system in a 27-year field experiment,to understand the effects of long-term fertilization on the distributions of OC and N in aggregates and to examine the recovery of soil OC and N in a highland agroecosystem.Manure fertilizer significantly decreased soil bulk density but increased the amount of coarse fractions and their associated OC and N stocks in the soils of both systems.Fertilizers N+phosphorus(P) and manure had similar effects on total soil OC and N stocks in both systems,but had larger effects on the OC and N stocks in>2 mm aggregates in the legume-grain rotation system than in the continuous winter wheat system.The application of P increased the OC and N stocks in>2 mm aggregates and decreased the loss of N from chemical fertilizers in the legume-grain rotation system.The results from this study suggested that P fertilizer should be applied for legume-included cropping systems and that manure with or without chemical fertilizers should be applied for semiarid cropping systems in order to enhance OC and N accumulation in soils. | HAO Yajun WANG Yuhong CHANG Qingrui WEI Xiaorong | 2017 | Pedosphere2017，27，4： | 3 |

| 7 | Highly efficient catalytic performances of nitro compounds via hierarchical PdNPs-loaded MXene/polymer nanocomposites synthesized through electrospinning strategy for wastewater treatment显示文摘The problem of water pollution has become increasingly serious,and it has already threatened the survival of mankind and has become an obstacle to the healthy development of human health.Here,we prepared a novel polyvinyl alcohol(PVA)/polyacrylic acid(PAA)/MXene fiber membrane by electrospinning.After heat treatment of film and subsequent modification with Pd nanoparticles,PVA/PAA/MXene@PdNPs composite nanofiber membrane with high specific surface area and excellent catalytic performance was finally prepared.The uniform distribution of MXene sheets in the composite fiber membrane not only solves the problem that the MXene sheet is not easy to be monolayerized,but also can grow the self-reduced Pd nanoparticles on the MXene sheets.In addition,the composite nanofiber membrane exhibits excellent catalytic ability and cycle stability for 4-nitrophenol(4-NP)and 2-nitrophenol(2-NA),providing new strategy for the study of catalytic composite materials related to degradation of wastewater. | Juanjuan Yin Fangke Zhan Tifeng Jiao Huizhen Deng Guodong Zou Zhenhua Bai Qingrui Zhang Qiuming Peng | 2020 | Chinese Chemical Letters2020，31，4： | 3 |
| 8 | Ferric ion-ascorbic acid complex catalyzed calcium peroxide for organic wastewater treatment:Optimized by response surface method显示文摘Hydrogen peroxide(H_(2)O_(2))disproportionation,iron precipitation,and narrow pH range are the drawbacks of traditional Fenton process.To surmount these barriers,we proposed a ferric ion(Fe^(3+))-ascorbic acid(AA)complex catalyzed calcium peroxide(CaO_(2))Fenton-like system to remove organic dyes in water.This collaborative Fe^(3+)/AA/CaO_(2)system presented an obvious improvement in the methyl orange(MO)decolorization,and also effectively eliminated other dyes.Response surface method was employed to optimize the running parameters for this coupling process.Under the optimized arguments(2.76 mmol/L Fe^(3+),0.68 mmol/L AA,and 4 mmol/L CaO_(2)),the MO removal achieved 98.90%after 15 min at pH 6.50,which was close to the computed outcome of 99.30%.Furthermore,this Fenton-like system could perform well in a wide range of pH(3-11),and enhance the H_(2)O_(2)decomposition and Fe ions recycle.The scavenger experiment result indicated that hydroxyl radical,superoxide anion free radical,and singlet oxygen were acted on the dye elimination.Moreover,electron spin resonance analysis corroborated that the existences of these active species in the Fe^(3+)/AA/CaO_(2)system.This study could advance the development of Fenton-like technique in organic effluent disposal. | Deling Yuan Chen Zhang Shoufeng Tang Zetao Wang Qina Sun Xiaoyu Zhang Tifeng Jiao Qingrui Zhang | 2021 | Chinese Chemical Letters2021，32，11： | 2 |
| 9 | Hydroelastic interaction between water waves and thin elastic plate floating on three-layer fluid显示文摘The wave-induced hydroelastic responses of a thin elastic plate floating on a three-layer fluid, under the assumption of linear potential flow, are investigated for two-dimensional cases. The effect of the lateral stretching or compressive stress is taken into account for plates of either semi-infinite or finite length. An explicit expression for the dispersion relation of the flexural-gravity wave in a three-layer fluid is analytically deduced. The equations for the velocity potential and the wave elevations are solved with the method of matched eigenfunction expansions. To simplify the calculation on the unknown expansion coefficients, a new inner product with orthogonality is proposed for the three-layer fluid, in which the vertical eigenfunctions in the open-water region are involved. The accuracy of the numerical results is checked with an energy conservation equation, representing the energy flux relation among three incident wave modes and the elastic plate. The effects of the lateral stresses on the hydroelastic responses are discussed in detail. | Qingrui MENG Dongqiang LU | 2017 | Applied Mathematics and Mechanics(English Edition)2017，38，4： | 2 |
| 10 | Selective adsorption of phosphate in water using lanthanum-based nanomaterials:A critical review显示文摘In recent years,lanthanum-based nanomaterials(La-NMs)are selected as an efficient nano-adsorbent for phosphate removal because La3+has a strong affinity with oxygen-donor atoms from phosphate.Additionally,there are a broad interest and literature base for the effect of different synthesis optimization and environmental parameters on the adsorption performance of La-NMs.A considerable amount of research has also investigated the regeneration and application of La-NMs to real wastewater in a laboratory scale.Based on the literature survey,it was found that La-NMs are often produced via co-precipitation and hydrothermal methods.Moreover,phosphate’s adsorption process and behavior onto La-NMs are described well with the pseudo-second-order model and Langmuir model.The interaction mechanism between phosphate and La-NMs are dominated by ligand exchange,surface complexation and electrostatic attraction.Furthermore,phosphate could easily desorb from La-NMs due to the weak H-bonding interaction between phosphate and the H-bond acceptor groups on the surface of La-NMs.Despite the wealth of literature available in this area,there is a lack of systematic review to evaluate the gaps in the use of La-NMs to eliminate phosphate in water.In this review,we mainly summarize and discuss the role and the effect of the synthesis techniques on the physicochemical properties and the adsorption behavior of La-NMs.The possible adsorption mechanism,regeneration efficiency,and the application of La-NMs to the real environmental samples are also presented and highlighted. | Mamitiana Roger Razanajatovo Wenyan Gao Yaran Song Xuan Zhao Qina Sun Qingrui Zhang | 2021 | Chinese Chemical Letters2021，32，9： | 2 |

| 20 | Performance Evaluation Indicators of Space Dynamic Networks under Broadcast Mechanism显示文摘Large-scale heterogeneous constellations will be the major forms of future space-based systems,and the implementation of numerous derived applications depends mainly on intersatellite communication.The nodes representing heterogeneous satellites will form the networks with rapidly changing topology.However,few researches have been carried out for such networks.This paper studies the broadcast mechanism for space dynamic networks and establishes centralized and distributed routing framework.And then,performance evaluation indicators are proposed to evaluate both the connectivity of dynamic networks and the effectiveness of routing algorithms.Finally,we examine the performance of multigroup networks and verify the rationality of corresponding indicators.We also explore the impact of information survival time which directly affects the delivery ratio and,if unfortunately,may waste the communication resources.Empirical conclusion about the survival time is given in the final part.We believe the performance indicators and the routing algorithms proposed in this paper are great help to future space-based system and both the broadcast mechanism designing. | Zipeng Ye Qingrui Zhou | 2021 | Space(Science & Technology)2021，，1： | 1 |
