| 1 | Change in current and future geographic distributions of Ulmus lamellosa in China显示文摘Prediction of potential geographic distributions is important for species protection and habitat restoration.Ulmus lamellosa is an endangered and endemic species in China for which conservation efforts are required.The maximum entropy(MaxEnt) model was used to predict the current and future geographic distribution(from 2030 to 2070) of U.lamellosa in China and discuss the reasons for changes in climatic suitability.The MaxEnt model provided a good fit to our data as confirmed by an AUC value of 0.948.The suitable areas for U.lamellosa were primarily projected in the northern part of China from 2030 to2070, especially in Liaoning province.The variables'temperature seasonality', 'precipitation of wettest month' and 'precipitation of warmest quarter' were the most influential climatic variables in limiting the distribution of U.lamellosa.Our results clearly predict the future impacts of climate change on the geographic distribution of U.lamellosa and this can help prioritize design of localized conservation strategies in China. | Dongting Yan Wei Chen Li Liu Jing Li Lin Liu Yiling Wang | 2018 | Journal of Forestry Research2018，29，4： | 2 |
| 2 | Superconducting gap evolution of kagome metal CsV3Sb5 under pressure显示文摘Kagome superconductors AV3Sb5(A=Cs,V,Sb) have served as an ideal platform to unveil the intriguing competitions between charge-density-wave(CDW),superconductivity and possible nontrivial topological states.We report soft point-contact spectroscopy(SPCS) studies on CsV3Sb5under pressure up to 2.5 GPa.Its superconducting transition temperature Tcand gaps for SPCS at pressure P=0.1 GPa suggest the absence of the adverse local strain effect as observed in point-contacts at ambient pressure,while the SPCS-determined Tcunder hydrostatic pressure deviates from the reported double dome feature below 2.5 GPa.Three distinct gap values in CsV3Sb5are proposed to exist through the whole pressure range with 2Δ1/kBTc≤1,2Δ2/kBTc~2.3-3.0 and 2Δ3/kBTc>3.5.The two smaller gaps for 2Δ1/kBTc≤1 and 2Δ2/kBTc~2.3-3.0 are robust under pressure,while there is no trace of the largest gap 2Δ3/kBTc>3.5 for SPCS in the c direction with P≤P1=0.7 GPa and P≥ P2=2.0 GPa and it becomes observable in the pressure range of(P1,P2),suggesting a complex relation between CDW and superconductivity between(P1,P2). | Dongting Zhang Chufan Chen Lichang Yin Yan'En Huang Fengrui Shi Yi Liu Xiaofeng Xu Huiqiu Yuan Xin Lu | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，2： | 2 |
| 3 | Effective removal of chlorinated organic pollutants by bimetallic iron-nickel sulfide activation of peroxydisulfate显示文摘Chlorinated organic pollutants(COPs)have caused serious contaminants in soil and groundwater,hence developing methods to remove these pollutants is necessary and urgent.By a simple hydrothermal method,we synthesized the bimetallic iron-nickel sulfide(FeNiS)particles which exhibited excellent catalytic property of COPs removal.FeNiS was chosen as the peroxydisulfate(PDS)activator to removal COPs including 4-chlorophenol(4-CP),1,4-dichlorophenol(1,4-DCP)and 2,4,6-trichlorophenol(2,4,6-TCP).The results show that FeNiS can efficiently activate PDS to produce sulfate radical(SO4·-)which plays major role in the oxidative dechlorination and degradation due to its strong oxidizing property and the ability of producing hydroxyl radicals(·OH)in the alkaline condition.Meanwhile,the Cl-abscised from COPs during the dechlorination can turn into the chlorine radicals and enhance the degradation and cause further mineralization of intermediate products.This bimetallic FeNiS catalyst is a promising PDS activator for removal of chlorinated organics. | Xuan Yan Dongting Yue Chao Guo Songling Wang Xufang Qian Yixin Zhao | 2020 | Chinese Chemical Letters2020，31，6： | 1 |
| 4 | Facile and scalable fabrication of lithiophilic Cu_(x)O enables stable lithium metal anode显示文摘Equipped with highest-energy density anode,lithium metal batteries are of great interests for the nextgeneration energy storage systems.However,the existing problems like uneven Li deposition,large volume expansion and short cycling lifespan severely retard the implementation of Li metal anodes.Herein,we report an in-situ formed Cu_(x)O nanofiber network synthesized by facile and scalable calcination process and employ as stable lithium metal anode.The CuO/Cu_(2)O ratio in the lithiophilic Cu_(x)O network can be adjusted through an optimal annealing time,thus guiding the homogeneous distribution of Li atoms and regulating the repeated plating/stripping processes.As a result,Li@Cu_(x)O 3D scaffold displays an ultralow overpotential of 7.7 mV,long cycling life for more than 1000 h in symmetric cell,and exceptional stability for LiFePO_(4)//Li full cells.This work provides guidelines for the design and fabrication of lithiophilic 3D matrixes and advances the practical use of lithium metal batteries. | Yanmei Nie Xiangyu Dai Jiexi Wang Zhengfang Qian Zhixing Wang Huajun Guo Guochun Yan Dongting Jiang Renheng Wang | 2022 | Journal of Energy Chemistry2022，，12： | 0 |
