| 1 | Intensification of the East Asian Monsoon in Southern China at about300-400 kaBP Inferred from Eolian Deposits in the Middle-lower Reaches of the Yangtze River显示文摘In the East Asian monsoon region,eolian deposits widely distributed in the middle-lower reaches of the Yantgze River are among the best materials available for studies on Quaternary climate change in the subtropical zone of Southern China.Typical eolian deposits in this region include upper Xiashu Loess(XL) and underlying Vermiculated Red Soil(VRS) layers.In this paper,chronological and paleoclimatic studies are conducted on an eolian deposit sequence near Jiujiang(JJ) city in northern Jiangxi province.A magnetostratigraphic study,combined with optically stimulated luminescence(OSL) dating,is conducted on the JJ section and provides further evidence that eolian deposits in the middle-lower reaches of the Yangtze River have been formed since the late Early Pleistocene,and that the boundary age between the XL and VRS layers is about 300-400 kaBP.In grain-size records of the JJ section,the median grain-size and content of the >30 μm size fraction increase sharply after 300-400 kaBP,representing an East Asian winter monsoon intensification event.Further pollen analysis reveals differing pollen assemblages before and after 300-400 kaBP:there is an evident increase in plants adapted to grow in a warm humid environment after 300-400 kaBP,implying an increase in precipitation caused by intensification of the East Asian summer monsoon.Global ice volume and uplift of the Tibet Plateau(TP) are regarded as crucial factors influencing variations of the East Asian monsoon on a long-term scale.The deep-sea δ^(18)O record,which reflects variations in global ice volume,shows no obvious change after 300-400 kaBP.Moreover,the influence of global ice volume changes on the East Asian summer and winter monsoons is inverse;the global ice volume increase(decrease) implies a strengthened(weakened) winter monsoon and weakened(strengthened) summer monsoon.We therefore interpret the coupled intensifications of the East Asian summer and winter monsoons at about 300-400 kaBP to the uplift of the TP in the Middle Pleistocene.This climate event is also documented in eolian deposits from the southern margin of the Chinese Loess Plateau(CLP) and from the desert-loess transitional belt.However,it is not recorded in the loess-paleosol sequences from the central part of the CLP,thereby indicating differing climate responses to TP uplift in different regions,which requires further study. | QI Lin QIAO Yansong LI Yuehui WANG Yan PENG Shasha HE Zexin YANG Shuaibin HAN Chao ZHANG Xujiao | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 3 |
| 2 | Preparation of Palygorskite-based Phase Change Composites for Thermal Energy Storage and Their Applications in Trombe Walls显示文摘Palygorskite/paraffin phase-change composites were prepared by the combination of purified palygorskite clay and sliced paraffin. Then, this composite was used in the Trombe wall to improve its energy storage ability. Further, its energy storage ability was compared to that of ordinary concrete wall through contrastive test. The experiments show that palygorskite clay is a type of clay mineral with strong adsorption ability, and the purity of natural palygorskite clay can reach up to 97.1% after certain purification processes. Paraffin is well adsorbed by palygorskite, and the test results show that the optimal adsorption ratio is palygorskite: paraffin = 2:1(mass ratio). Palygorskite/paraffin phase change composites can be obtained by using palygorskite as the adsorbing medium to adsorb paraffin. The composite materials exhibit good heat storage(release) performance, which can store heat with increasing environment temperature and release heat with decreasing temperature. This property not only increases the inertia to environment temperature change, but also promotes the energy migration in different time and space, thus achieving a certain energy-saving effect. The application of palygorskite/paraffin phase change composite materials to the Trombe wall can significantly reduce the fluctuation of indoor temperature and enhance the thermal inertia of indoor environment. From the aspect of energy storage effect, the Trombe wall fabricated using PCMs is significantly superior to the concrete wall with the same thickness. | 施韬 LI Shanshan 张豪 LI Zexin ZHU Min | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，6： | 2 |

| 9 | Zero-valent manganese nanoparticles coupled with different strong oxidants for thallium removal from wastewater显示文摘Nano zero-valent manganese(nZVMn,Mn^0)was prepared through a borohydride reduction method and coupled with different oxidants(persulfate(S2O8^2-),hypochlorite(CIO^-),or hydrogen peroxide(H2O2))to remove thallium(TI)from wastewater.The surface of Mn°was readily oxidized to form a core-shell composite(MnOx@Mn°),which consists of Mn°as the inner core and MnOr(MnO,M112O3,and Mn3O4)as the outer layer.When Mn^0 was added alone,effective T1(I)removal was achieved at high pH levels(>12).The Mn-H2O2 system was only effective in T1(I)removal at high pH(>12),while the Mn^0-S2O8^0or Mn0-ClO^-system had excellent T1(I)removal(>96%)over a broad pH range(4-12).The Mn-S2O8 oxidation system provided the best resistance to interference from an external organic matrix.The isotherm of T1(I)removal through the Mn°-S2O8^2-system followed the Freundlich model.The Mn°nanomaterials can activate persulfate to produce sulfate radicals and hydroxyl radicals.Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy suggested that oxidation-induced precipitation,surface adsorption,and electrostatic attraction are the main mechanisms for T1(I)removal resulting from the combination of Mn^0 and oxidants.Mn^0coupled with S2O8^2-/ClO^-is a novel and effective technique for T1(I)removal,and its application in other fields is worthy of further investigation. | Keke Li Huosheng Li Tangfu Xiao Gaosheng Zhang Aiping Liang Ping Zhang Lianhua Lin Zexin Chen Xinyu Cao Jianyou Long | 2020 | Frontiers of Environmental Science & Engineering2020，14，2： | 1 |
| 10 | Surface photodynamic ion sterilization of ITO-Cu_(2)O/ZnO preventing touch infection显示文摘Pathogenic microbial infections are threatening the people’s health and even life.The most common channel of infections can be caused by skin contact,especially hand touching facilities such as touching screen.In this work,Cu_(2)O covered with ZnO nanofilm was prepared on the surface of indium tin oxide conductive glass by electrodeposition and the followed atomic layer deposition process.This composite coating had a light transmittance of 71.5%,which met the light transmission needs of touch screen device.Electron spin resonance spectra showed that composite materials can generate more reactive oxygen species(ROS)than a single component under solar light irradiation.This was because a p-n junction with a built-in electric field was formed at the interface after Cu_(2)O contacting with ZnO.In the process of photocatalysis,photogenerated electrons and holes migrated at the interface driven by the built-in electric field,which promoted the separation of carriers.The antibacterial rate against Staphylococcus aureus reached 92.5%after 3 min of light irradiation with simulated sunlight due to the synergy of ROS and Cu ions,Zn ions.Therefore,this work may provide a potential method for antibacterial application of preventing hand touch infections. | Zexin Liu Xiangmei Liu Zhenduo Cui Yufeng Zheng Zhaoyang Li Yanqin Liang Xubo Yuan Shengli Zhu Shuilin Wu | 2022 | Journal of Materials Science & Technology2022，，27： | 1 |

| 12 | GmGPDH12,a mitochondrial FAD-GPDH from soybean, increases salt and osmotic stress resistance by modulating redox state and respiration显示文摘In plants,glycerol-3-phosphate dehydrogenase(GPDH)catalyzes the interconversion of glycerol-3-phosphate(G3P)and dihydroxyacetone phosphate(DHAP)coupled to the reduction/oxidation of the nicotinamide adenine dinucleotide(NADH)pool,and plays a central role in glycerolipid metabolism and stress response.Previous studies have focused mainly on the NAD+-dependent GPDH isoforms,neglecting the role of flavin adenine dinucleotide(FAD)-dependent GPDHs.We isolated and characterized three mitochondrialtargeted FAD-GPDHs in soybean,of which one isoform(GmGPDH12)showed a significant transcriptional response to NaCl and mannitol treatments,suggesting the existence of a major FAD-GPDH isoform acting in soybean responses to salt and osmotic stress.An enzyme kinetic assay showed that the purified GmGPDH12 protein possessed the capacity to oxidize G3P to DHAP in the presence of FAD.Overexpression and RNA interference of GmGPDH12 in soybean hairy roots resulted in elevated tolerance and sensitivity to salt and osmotic stress,respectively.G3P contents were significantly lower in GmGPDH12-overexpressing hair roots and higher in knockdown hair roots,indicating that GmGPDH12 was essential for G3P catabolism.A significant perturbation in redox status of NADH,ascorbic acid(ASA)and glutathione(GSH)pools was observed in GmGPDH12-knockdown plants under stress conditions.The impaired redox balance was manifested by higher reactive oxygen species generation and consequent cell damage or death;however,overexpressing plants showed the opposite results for these traits.GmGPDH12 overexpression contributed to maintaining constant respiration rates under salt or osmotic stress by regulating mRNA levels of key mitochondrial respiratory enzymes.This study provides new evidence for the roles of mitochondria-localized GmGPDH12 in conferring resistance to salt or osmotic stress by maintaining cellular redox homeostasis,protecting cells and respiration from oxidative injury. | Ying Zhao Xin Li Zexin Zhang Wenjing Pan Sinan Li Yun Xing Wanying Xin Zhanguo Zhang Zhenbang Hu Chunyan Liu Xiaoxia Wu Zhaoming Qi Dawei Xin Qingshan Chen | 2021 | The Crop Journal2021，9，1： | 1 |

| 15 | Simultaneous enhancement of strength and ductility in friction stir processed 2205 duplex stainless steel with a bimodal structure:experiments and crystal plasticity modeling显示文摘Achieving excellent strength-ductility synergy is a long-lasting research theme for structural materials.However,attempts to enhance strength usually induce a loss of ductility,i.e.,the strength-ductility trade-off.In the present study,the strength-ductility trade-off in duplex stainless steel(DSS)was overcome by developing a bimodal structure using friction stir processing(FSP).The ultimate tensile strength and elongation were improved by 140%and 109%,respectively,compared with those of the asreceived materials.Plastic deformation and concurrent dynamic recrystallization(DRX)during FSP were responsible for the formation of bimodal structure.Incompatible deformation resulted in the accumulation of dislocations at the phase boundaries,which triggered interpenetrating nucleation between the austenite and ferrite phases during DRX,leading to a bimodal structure.The in situ mechanical responses of the bimodal structure during tensile deformation were investigated by crystal plasticity finite element modeling(CPFEM).The stress field distribution obtained from CPFEM revealed that the simultaneous enhancement of strength and ductility in a bimodal structure could be attributed to the formation of a unique dispersion-strengthened system with the austenite and ferrite phases.It is indicated that the present design of alternating fine austenite and coarse ferrite layers is a promising strategy for optimizing the mechanical properties of DSSs. | Yanying Hu Zexin Fang Yongbing Peng Weiqi Yang Xianfeng Ma Jinglong Li Yunqiang Zhao Biao Wang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 0 |
| 16 | Genetic diversity analysis of Hepatacodium miconioides at different altitude in Tiantai Mountain,Zhejiang Province,China and its relationship with environmental factors显示文摘The genetic diversity within and among populations of Hepatacodium miconioides collected at three different altitudes in Tiantai Mountain,Zhejiang Province and its relationships to environmental factors were analyzed by random amplified polymorphic DNA(RAPD)technique.Amplification using 12 random primers of 60 plants and 122 repetitive loci were produced.The percentage of polymorphic loci of three populations ranged from 18.85%to 23.77%with an average of 21.86%,indicating the relatively low genetic diversity of H.miconioides.The average Shannon index of phenotypic diversity(0.1329)and Nei index(0.0925)within populations were relatively low.A distinct genetic differentiation existed among populations of H.miconioides in spite of the relatively small geographical distribution.The average genetic diversity within populations of H.miconioides accounted for 33.58%of the total genetic diversity while the genetic diversity among populations accounted for 66.42%as estimated by the Shannon index of phenotypic diversity,The genetic differentiation among populations of H.miconioides was 0.6546,as estimated by Nei index.The gene flow estimated from GST was only 0.2656 and it indicated that gene flow among populations of H.miconioides was relatively low.The mean value of the genetic identity among populations of H.miconioides was 0.7126 and the average of genetic distance of H.miconioides was 0.3412.The genetic identity between populations at the elevation of 990 m and at the elevation of 780 m was the highest.The genetic identity between population at the elevation 500 m and other two populations was relatively low.The correlation analysis showed that the genetic diversity within populations was significantly related with the soil total nitrogen. | Jin Zexin Li Junmin | 2006 | Frontiers in Biology2006，1，2： | 0 |
| 17 | IFE based nanosensor composed of UCNPs and Fe(Ⅱ)-phenanthroline for detection of hypochlorous acid and periodic acid显示文摘Oxidizing CIO^(-)and IO_(4)^(-)exist widely in environment and are closely related to the health of organisms.Accordingly,fast,sensitive,and direct detection of the two species is significant.Using IFE in UCNPs@PAA and Fe(Ⅱ)-phenanthroline system,an elegant ratiometric fluorescent nanosensor,without noble metal nanoparticle,was designed for the detection of CIO-and IO4-.Fe(Ⅱ)-phenanthroline complex is used as fluorescent absorber,which can quench green light of UCNPs with gradually varied extent depending on the concentration of Fe(Ⅱ).The linear zone extends to 800 and 120μmol/L while the detection limit is 1.30 and 0.58μmol/L for NaCIO and NaIO_(4),respectively.Finally,the nanosensor was successfully applied to detect NaCIO and NaIO4spiked in milk,spring water,and tap water with good recoveries. | Haining Song Haifeng Zhou Qianqian Zhuang Zexin Li Fenglei Sun Zhenlei Yuan Youxin Lou Guangjun Zhou Yujun Zhao | 2023 | Journal of Rare Earths2023，41，2： | 0 |

| 19 | Ion Migration and Accumulation in Halide Perovskite Solar Cells显示文摘Comprehensive Summary The halide perovskite semiconductors-based solar cells(PVSCs)show great promise as next-generation renewable energy sources,with the merits of low cost,high performance,good flexibility,etc.A major difference distinguishing the perovskite semiconductors from others lies in their ionic feature.This intrinsic property induces“freely-moving”ions to migrate and accumulate in the perovskite films and devices under different external stresses.As a charge carrier,these processes will strongly couple with the electronic process,and dramatically affect the performance and stability of PVSCs.This review summarizes and discusses the recent progresses and fundamental understandings of ion migration and accumulation behaviors in PVSCs.First,the basic principles of the general ion migration are reviewed.Second,following the fundamental understandings,the critical factors,e.g.,ion migration activation energy,ion density,ion diffusion coefficient,etc.,are extracted to understand the ion migration and accumulation in perovskite film.Third,the principles governing ion accumulation behaviors under different external stresses are discussed.Finally,the effect of ion migration and accumulation on band bending,and device performance is presented.Therefore,we hope this review provides a tutorial and insightful perspective regarding the most prominent ionic feature of perovskite semiconductors and their application for photovoltaics. | Lijian Zuo Zexin Li Hongzheng Chen | 2023 | Chinese Journal of Chemistry2023，41，7： | 0 |
| 20 | Experimental study on the key factors of low-loss threshing of high-moisture maize显示文摘The rates of maize breakage and entrainment loss are high in the harvest of high-moisture maize,which remains an issue with the development of agricultural mechanization.In order to reduce the maize breakage and entrainment loss rates,the correlations among key factors,such as the threshing cylinder speed,concave clearance and feeding rate,and the rates of breakage and entrainment loss during high-moisture maize harvesting were studied in this paper.A single-factor experiment was carried out using a single-longitudinal-axial flow maize harvester,and an orthogonal experiment was carried out using single-and double-longitudinal-axial flow maize harvesters with the Taguchi experimental design method.The single-factor experiment revealed that when the cylinder speed increased,the breakage rate of maize decreased first and then increased,while the entrainment loss rate decreased.The breakage rate of maize decreased as the concave clearance increased,while the entrainment loss rate decreased first and then increased.The optimum value of the concave clearance was positively correlated with the ear diameter of maize;Additionally,the minimum breakage rate of maize occurred when the feeding rate was at the rated value,and the entrainment loss rate increased as the feeding rate increased.The orthogonal experiments revealed that the importance of cylinder speed,feeding rate,concave clearance on the maize breakage and entrainment loss rates were in descending order.The optimum values of parameters for the single-longitudinal-axial flow maize harvester were 370 r/min cylinder speed,40 mm concave clearance and 10 kg/s feeding rate.The optimum values of parameters the double-longitudinal-axial flow maize harvester were 550 r/min cylinder speed,35 mm concave clearance and 10 kg/s feeding rate.The research can provide a reference for parameter configuration and control strategy for the longitudinal-axial flow maize harvester with high-moisture maize. | Xiaolong Zhu Ruijuan Chi Yuefeng Du Jiahao Qin Zexin Xiong Weitong Zhang Xiaoyu Li | 2020 | International Journal of Agricultural and Biological Engineering2020，13，5： | 0 |
