1Soil Erosion Changes over the Past Five Decades in the Red Soil Region of Southern China显示文摘This paper reports the dynamic changes of soil and water loss in the red soil region of Southern China since the 1950s. The red soil region covers eight provinces: Jiangxi, Zhejiang, Fujian, Anhui, Hubei, Hunan, Guangdong and Hainan. From the 1950s to 1986, the annual rate of soil erosion increased by 3.4%. From 1986 to 1996 and from 1996 to 2000, the annual rates of soil erosion decreased by 2.0% and 0.32%, respectively. Field surveys showed that from 2000 to 2005, the area of soil and water loss decreased annually by 1.2%. This decrease was a result of large-scale erosion control activities across China. Although the eroded soil has been restored, the restoration process is very slow and full restoration will take a long time. Our report suggests that controlling soil and water loss is a challenging task, and additional measures must be taken to effectively control the soil erosion in the red soil region.LIANG Yin LI Decheng LU Xixi YANG Xuan PAN Xianzhang MU Huan SHI Deming ZHANG Bin 2010Journal of Mountain Science2010,7,1:18
2Bone marrow stromal cells as a therapeutic treatment for ischemic stroke显示文摘Cerebral ischemia remains the most frequent cause of death and quality-of-life impairments due to neurological deficits, and accounts for the majority of total healthcare costs. However, treatments for cerebral ischemia are limited. Over the last decade, bone marrow stromal cell(BMSC) therapy has emerged as a particularly appealing option, as it is possible to help patients even when initiated days or even weeks after the ischemic insult. BMSCs are a class of multipotent, self-renewing cells that give rise to differentiated progeny when implanted into appropriate tissues. Therapeutic effects of BMSC treatment for ischemic stroke, including sensory and motor recovery, have been reported in pre-clinical studies and clinical trials. In this article, we review the recent progress in BMSC-based therapy for ischemic stroke, focusing on the route of delivery and pre-processing of BMSCs. Selecting an optimal delivery route is of particular importance. The ideal approach, as well as the least risky, for translational applications still requires further identification. Appropriate preprocessing of BMSCs or combination therapy has the benefit of achieving the maximum possible restoration. Further pre-clinical studies are required to determine the time-window for transplantation and the appropriate dosage of cells.Zizhen Yang Lei Zhu Fangqin Li Jing Wang Huan Wan Yujun Pan 2014Neuroscience Bulletin2014,30,3:16
3A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice.Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan 2019Cell Research2019,29,10:13
4Photodegradation of 17α-ethynylestradiol in dissolved humic substances solution:Kinetics,mechanism and estrogenicity variation显示文摘17α-Ethynylestradiol(EE2) in natural waters may cause adverse effects on organisms due to its high estrogenic potency. Laboratory studies were performed to study the effects of a local humic acid(LHA), fulvic acid(LFA) and Aldrich humic acid(AHA) on the photochemical behavior and estrogenic potency of EE2. Here photolytic experiments demonstrated that pure aqueous EE2 could undergo direct and self-sensitized photodegradation at a global rate of 0.0068 hr^(-1).Photodegradation rate of EE2 in 5.0 mg/L dissolved humic substances(DHS) was determined to be 0.0274, 0.0296 and 0.0254 hr^(-1) for LHA, LFA and AHA, respectively. Reactive oxygen species(ROS) and triplet dissolved humic substances(~3DHS*) scavenging experiments indicated that the promotion effect of DHS on EE2 photodegradation was mainly aroused by the reactions of HOU(35%–50%),~1O_2(<10%) andDHS*(22%–34%). However, the photodegradation of EE2 could also be inhibited when DHS exceeded the threshold of 10 mg/L. Three hydroxylation products of EE2 were identified using GC–MS and their formation pathways were also proposed. In vitro estrogenicity tests showed that EE2 was transformed into chemicals without estrogenic potency. These findings could extend our knowledge on the photochemical behaviors of steroid estrogens in sunlit natural waters.Dong Ren Bin Huang Dan Xiong Huan He Xiangqi Meng Xuejun Pan 2017Journal of Environmental Sciences2017,29,4:9

6Simple fabrication of superhydrophobic PLA with honeycomb-like structures for high-efficiency oil-water separation显示文摘Polylactic acid(PLA) is one of the most suitable candidates for environmental pollution treatment because of its biodegradability which will not cause secondary pollution to the environment after application.However,there is still a lack of a green and facile way to prepare PLA oil-water separation materials.In this work,a water-assisted thermally induced phase separation method for the preparation of superhydrophobic PLA oil-water separation material with honeycomb-like structures is reported.The PLA material shows great ability in application and could adsorb 27.3 times oil to its own weight.In addition,it could also be applicated as a filter with excellent efficiency(50.9 m^3 m^(-2) h^(-1)).Xiaolong Wang Yamin Pan Huan Yuan Meng Su Chunguang Shao Chuntai Liu Zhanhu Guo Changyu Shen Xianhu Liu 2020Chinese Chemical Letters2020,31,2:7
7Modification performance on 4032 Al alloy by using Al–10Sr master alloys manufactured from different processes显示文摘The microstructures and modification performance on 4032 aluminum alloy of the Al–10Sr master alloy wire prepared from 'direct reaction-hot extrusion' and the trapezoidal block from 'direct reaction' were systemically studied by using optical metallurgical microscope, XRD and SEM. It was found that the preparation processes exhibited a significant effect on the microstructures of the Al–10Sr, which thereby influenced its modification performance. It has been found that when the Al–10Sr alloy wire was used, a desirable modification was obtained after 2 min and reached to the best performance at 60 min, and the optimum Sr addition amount was 0.04–0.06 wt%, and the good modification performance was kept even after 300 min. However, when the Al–10Sr alloy trapezoidal block was used, a desirable modification was started after 30 min and reached to the best performance as long as 120 min, and the optimum Sr addition amount was 0.06–0.08 wt%, and the effective modification period was only180 min. Therefore, comparing with the Al–10Sr alloy trapezoidal block, the Al–10Sr alloy wire had better modification efficiency, which not only reduced the Sr addition amount of about 30%, but also greatly decreased the incubation time and improved the ability of anti-fading.Chengwei Liao Jianchun Chen Yunlong Li Huan Chen Chunxu Pan 2014Progress in Natural Science:Materials International2014,24,2:6
8Upgrade of macromolecular crystallography beamline BL17U1at SSRF显示文摘Beamline BL17 U1 at Shanghai Synchrotron Radiation Facility is an energy-tunable macromolecular crystallography beamline that has been in user operation since 2009. Growing demand from the user community for a small beam and related experimental methods have motivated upgrades of the devices in the endstation.Minibeam modes have already been developed for operation. A self-integrated diffractometer reduces the sphere of confusion of the rotatory axis to 1μm. The new diffractometer is equipped with an upgraded on-axis viewing system that can improve the resolving power. Additionally,the area detector was also upgraded to the newest generation of detectors, the EIGER X 16 M, which can collect data at 133 Hz. After these upgrades, the endstation became virtually new. This paper covers the upgrade of the endstation devices and gives the first data collection results.Qi-Sheng Wang Kun-Hao Zhang Yin Cui Zhi-Jun Wang Qiang-Yan Pan Ke Liu Bo Sun Huan Zhou Min-Jun Li Qin Xu Chun-Yan Xu Feng Yu Jian-Hua He 2018Nuclear Science and Techniques2018,29,5:6

10Structural Engineering of Hierarchical Aerogels Comprised of Multi-dimensional Gradient Carbon Nanoarchitectures for Highly Efficient Microwave Absorption显示文摘Recently,multilevel structural carbon aerogels are deemed as attractive candidates for microwave absorbing materials.Nevertheless,excessive stack and agglomeration for low-dimension carbon nanomaterials inducing impedance mismatch are significant challenges.Herein,the delicate“3D helix-2D sheet-1D fiber-0D dot”hierarchical aerogels have been successfully synthesized,for the first time,by sequential processes of hydrothermal self-assembly and in-situ chemical vapor deposition method.Particularly,the graphene sheets are uniformly intercalated by 3D helical carbon nanocoils,which give a feasible solution to the mentioned problem and endows the as-obtained aerogel with abundant porous structures and better dielectric properties.Moreover,by adjusting the content of 0D core-shell structured particles and the parameters for growth of the 1D carbon nanofibers,tunable electromagnetic properties and excellent impedance matching are achieved,which plays a vital role in the microwave absorption performance.As expected,the optimized aerogels harvest excellent performance,including broad effective bandwidth and strong reflection loss at low filling ratio and thin thickness.This work gives valuable guidance and inspiration for the design of hierarchical materials comprised of dimensional gradient structures,which holds great application potential for electromagnetic wave attenuation.Yongpeng Zhao Xueqing Zuo Yuan Guo Hui Huang Hao Zhang Ting Wang Ningxuan Wen Huan Chen Tianze Cong Javid Muhammad Xuan Yang Xinnan Wang Zeng Fan Lujun Pan 2021Nano-Micro Letters2021,13,9:5
11Total glucosides of paeony improve complete freund’s adjuvant-induced rheumatoid arthritis in rats by inhibiting toll-like receptor 2-mediated tumor necrosis factor receptor-associated factor 6/nuclear factor-kappa B pathway activation显示文摘OBJECTIVE: To investigate the mechanism underlying anti-inflammatory and immunoregulatory effect of total glucosides of paeony(TGP) based on toll-like receptor 2(TLR2) mediated tumor necrosis factor(TNF) receptor-associated factor 6(TRAF6)/nuclear factor-kappa B(NF-κB) pathway activation in rats with rheumatoid arthritis.METHODS: Adjuvant arthritis(AA) model was developed by complete freund’s adjuvant(CFA) immunization. TGP(100, 50, 25 mg/kg) and celecoxib(2.8 mg/kg) were administered by intragastric administration for 21 d. Right hind paw swelling was assessed every 2 d. After 21 d, synovial changes of the ankle were detected by histopathology. CD4+and CD8+ T cell amounts in peripheral blood were measured by flow-cytometrically. Gene and protein levels of toll-like receptor(TLR)2, TRAF6, tumor necrosis factor ligand superfamily member 6(FASLG)in the spleen were assessed by RT-qPCR and Western Bolt, respectively. Nuclear expression of NF-κB p65 was detected by NF-κB p65 Assay Kit.RESULTS: Paw swelling and synovium lesions were obviously aggravated in AA rats. These symptoms were significantly relieved by TGP.The ratio of CD4+/CD8+ T cell was increased in AA rats, while TGP reduced this increased ratio.Gene and protein levels of splenic TLR2, TFAR6 and FASLG, and nuclear NF-κB p65 in AA rats were significantly increased, but overtly inhibited by TGP.CONCLUSION: These findings suggest that TGP’s anti-inflammatory effect onRA in rats with CFA may be related to the downregulation of TLR2/TRAF6/NF-κB pathway and the regulation of T cell subsets.Chen Huan Wen Yueqiang Pan Ting Xu Shijun 2019Journal of Traditional Chinese Medicine2019,39,4:5
12The treatment of black-odorous water using tower bipolar electro-flocculation including the removal of phosphorus,turbidity,sulfion,and oxygen enrichment显示文摘The large amount of municipal wastewater discharged into urban rivers sometimes exceeds the rivers’self-purification capacity leading to black-odorous polluted water.Electro-flocculation has emerged as a powerful remediation technology.Electro-flocculation in a bubble column tower with a bipolar electrode(BPE)was tested in an attempt to overcome the high resistance and weak gas-floatation observed with a monopolar electrode(MPE)in treating such water.The BPE reactor tested had a Ti/Ta2O_(5)-IrO_(2)anode and a graphite cathode with an iron or aluminum bipolar electrode suspended between them.It was tested for its ability to reduce turbidity,phosphate and sulphion and to increase the concentration of dissolved oxygen.The inclusion of the bipolar electrode was found to distinctly improved the system’s conductivity.The system’s electro-flocculation and electrical floatation removed turbidity,phosphate and sulphion completely,and the dissolved oxygen level improved from 0.29 to 6.28 mg/L.An aluminum bipolar electrode performed better than an iron one.Changes in the structure of the microbial community confirmed a significant improvement in water quality.Huan He Qinjin Yu Chaochao Lai Chen Zhang Muhan Liu Bin Huang Hongping Pu Xuejun Pan 2021Frontiers of Environmental Science & Engineering2021,15,2:5

15Comparing the performance of time series models with or without meteorological factors in predicting incident pulmonary tuberculosis in eastern China显示文摘Background: Many studies have compared the performance of time series models in predicting pulmonary tuberculosis(PTB),but few have considered the role of meteorological factors in their prediction models.This study aims to explore whether incorporating meteorological factors can improve the performance of time series models in predicting PTB.Methods:: We collected the monthly reported number of PTB cases and records of six meteorological factors in three cities of China from 2005 to 2018.Based on this data,we constructed three time series models,including an autoregressive integrated moving average(ARIMA)model,the ARIMA with exogenous variables(ARIMAX)model,and a recurrent neural network(RNN)model.The ARIMAX and RNN models incorporated meteorological factors,while the ARIMA model did not.The mean absolute percentage error(MAPE)and root mean square error(RMSE)were used to evaluate the performance of the models in predicting PTB cases in 2018.Results: Both the cross-correlation analysis and Spearman rank correlation test showed that PTB cases reported in the study areas were related to meteorological factors.The predictive performance of both the ARIMA and RNN models was improved after incorporating meteorological factors.The MAPEs of the ARIMA,ARIMAX,and RNN models were 12.54%,11.96%,and 12.36%in Xuzhou,15.57%,11.16%,and 14.09%in Nantong,and 9.70%,9.66%,and 12.50%in Wuxi,respectively.The RMSEs of the three models were 36.194,33.956,and 34.785 in Xuzhou,34.073,25.884,and 31.828 in Nantong,and 19.545,19.026,and 26.019 in Wuxi,respectively.Conclusions: Our study revealed a possible link between PTB and meteorological factors.Taking meteorological factors into consideration increased the accuracy of time series models in predicting PTB,and the ARIMAX model was superior to the ARIMA and RNN models in study settings.Zhong-Qi Li Hong-Qiu Pan Qiao Liuf Huan Song Jian-Ming Wang 2020Infectious Diseases of Poverty2020,9,6:4
16Scalable salt-templated directed synthesis of high-quality MoS_(2) nanosheets powders towards energetic and environmental applications显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDCs)have emerged as perfect platforms for developing applications in nano-electronics,catalysis,energy storage and environmental-related fields due to their superior properties.However,the low-cost,batch production of high-quality 2D TMDCs remains a huge challenge with the existing synthetic strategies.Herein,we present a scalable chemical vapor deposition(CVD)approach for the batch production of high-quality MoS_(2) nanosheet powders,by using naturally abundant,water-soluble and recyclable NaCl crystal powders as templates.The high-quality MoS_(2) nanosheets powders are achieved by a facile water dissolution-filtration process,by virtue of the excellent dispersibility of the as-grown products in water.The internal mechanism for the scalable synthesis strategy is explored.The applications of the MoS_(2) nanosheets powders are also demonstrated as catalysts or adsorbents in hydrogen evolution reaction(HER)and organic dyes adsorption,respectively.This work should hereby pave ways for the mass production and application of powdery TMDCs in energetic and environmental related fields.Lijie Zhu Pengfei Yang Yahuan Huan Shuangyuan Pan Zhaoqian Zhang Fangfang Cui Yuping Shi Shaolong Jiang Chunyu Xie Min Hong Jiatian Fu Jingyi Hu Yanfeng Zhang 2020Nano Research2020,13,11:4
17Growth of Carbon Nanocoils by Porous α-Fe2O3/SnO2 Catalyst and Its Buckypaper for High Efficient Adsorption显示文摘High-purity(99%)carbon nanocoils(CNCs)have been synthesized by using porousα-Fe2O3/SnO2 catalyst.The yield of CNCs reaches 9,098%after a 6 h growth.This value is much higher than the previously reported data,indicating that this method is promising to synthesize high-purity CNCs on a large scale.It is considered that an appropriate proportion of Fe and Sn,proper particle size distribution,and a loose-porous aggregate structure of the catalyst are the key points to the high-purity growth of CNCs.Benefiting from the high-purity preparation,a CNC Buckypaper was successfully prepared and the electrical,mechanical,and electrochemical properties were investigated comprehensively.Furthermore,as one of the practical applications,the CNC Buckypaper was successfully utilized as an efficient adsorbent for the removal of methylene blue dye from wastewater with an adsorption efficiency of 90.9%.This study provides a facile and economical route for preparing high-purity CNCs,which is suitable for large-quantity production.Furthermore,the fabrication of macroscopic CNC Buckypaper provides promising alternative of adsorbent or other practical applications.Yongpeng Zhao Jianzhen Wang Hui Huang Tianze Cong Shuaitao Yang Huan Chen Jiaqi Qin Muhammad Usman Zeng Fan Lujun Pan 2020Nano-Micro Letters2020,12,2:3
18Transverse mode instability mitigation in a high-power confined-doped fiber amplifier with good beam quality through seed laser control显示文摘In this work,a confined-doped fiber with the core/inner-cladding diameter of 40/250μm and a relative doping ratio of 0.75 is fabricated through a modified chemical vapor deposition method combined with the chelate gas deposition technique,and subsequently applied in a tandem-pumped fiber amplifier for high-power operation and transverse mode instability(TMI)mitigation.Notably,the impacts of the seed laser power and mode purity are preliminarily investigated through comparative experiments.It is found that the TMI threshold could be significantly affected by the seed laser mode purity.The possible mechanism behind this phenomenon is proposed and revealed through comprehensive comparative experiments and theoretical analysis.Finally,a maximum output power of 7.49 kW is obtained with the beam quality factor of approximately 1.83,which is the highest output power ever reported in a forward tandem-pumped confined-doped fiber amplifier.This work could provide a good reference and practical solution to improve the TMI threshold and realize high-power high-brightness fiber lasers.Hanshuo Wu Haobo Li Yi An Ruixian Li Xiao Chen Hu Xiao Liangjin Huang Huan Yang Zhiping Yan Jinyong Leng Zhiyong Pan Pu Zhou 2022High Power Laser Science and Engineering2022,10,6:3
19Sandstone-concrete interface transition zone (ITZ) damage and debonding micromechanisms under freeze-thaw显示文摘The sufficient bond between concrete and rock is an important prerequisite to ensure the effect of shotcrete support. However, in cold regions engineering protection system, the bond condition of rock and concrete surface is easily affected by freeze-thaw cycles, resulting in interface damage, debonding and even supporting failure. Understanding the micromechanisms of the damage and debonding of the rock-concrete interface is essential for improving the interface protection.Therefore, the micromorphology, micromechanical properties, and microdebonding evolution of the sandstone-concrete interface transition zone(ITZ) under varying freeze-thaw cycles(0, 5, 10, 15, 20) were studied using scanning electron microscope, stereoscopic microscope, and nano-indentation. Furthermore, the distribution range and evolution process of ITZ affected by freeze-thaw cycles were defined. Major findings of this study are as follows:(1) The microdamage evolution law of the ITZ under increasing freeze-thaw cycles is clarified, and the relationship between the number of cracks in the ITZ and freeze-thaw cycles is established;(2) As the number of freeze-thaw cycles increases, the ITZ's micromechanical strength decreases, and its development width tends to increase;(3) The damage and debonding evolution mechanisms of sandstone-concrete ITZ under freeze-thaw cycles is revealed, and its micromechanical evolution model induced by freeze-thaw cycles is proposed.YanJun Shen Huan Zhang JinYuan Zhang HongWei Yang Xu Wang Jia Pan 2021Research in Cold and Arid Regions2021,13,2:3
20Catalytic hydrogenation of aromatic nitro compounds by functionalized ionic liquids-stabilized nickel nanoparticles in aqueous phase:The influence of anions显示文摘Two kinds of nickel nanoparticles (NPs) well-dispersed in aqueous phase have been conveniently prepared by reducing nickel(II) salt with hydrazine in the presence of amino group (-NH2) functionalized ionic liquids:1-(3-aminopropyl)-2,3-dimethylimidazolium bromide ([AMMIM][Br]) and 1-(3-aminopropyl)-2,3-dimethylimidazolium acetate ([AMMIM][AcO]).The Ni(0) particles are composed of smaller ones which assemble in a blackberry-like shape.The Ni nanoparticles stabilized with [AMMIM][AcO] are much larger than those stabilized with [AMMIM][Br],and the former unexpectedly give much higher activity in the selective hydrogenation of citral and nitrobenzene (NB) in aqueous phase.The Ni(0) nanocatalysts dispersed in aqueous phase are stable enough to be reused at least five times without significant loss of catalytic activity and selectivity during the catalytic recycles.HU Yu YU YinYin ZHAO XiuGe YANG HanMing FENG Bo LI Huan QIAO YunXiang HUA Li PAN ZhenYan HOU ZhenShan 2010Science China Chemistry2010,53,7:3
