| 1 | Lopingian mixed floras from Linxi Formation in Soron area,Inner Mongolia显示文摘A lot of well-preserved plants from the Linxi Formation are collected in the Soron area,Inner Mongolia,consisting of 34 species of 16 genera. They are Late Permian in age. The flora is characterized by a lot of Angaran plants,such as Paracalamites,Comia,Rhachiphyllum,Iniopteris,Rufloria,etc. Some Cathaysian elements,such as Lobatannularia lingulata,L. multifolia,Fascipteris Cathaysiantus,F. densata,Taeniopteris szei,Cladophlebis liulinensis and C. permica,are also mixed within the present flora. This indicates that the Soron of Inner Mongolia was located in the sector between the Angaran and Cathysian floristic provinces in Lopingian. It is beneficial for depicting the location and the evolution of the Solenker--Xar Moron suture zone in the phytogeographic view. The transmigration of tropical and subtropical Cathaysian plants to the north indicates that the Paleoasian Ocean was closed during the late Permian along the suture zone. | ZHANG Dejun SUN Yuewu DING Haisheng YANG Zhenyuan TANG Lijing | 2014 | Global Geology2014，17，2： | 10 |
| 2 | Prussian blue and collagen loaded chitosan nanofibers with NIR-controlled NO release and photothermal activities for wound healing显示文摘Nitric oxide(NO)has emerged as a potential wound therapeutic agent due to its pivotal role in the wound healing processes.Nevertheless,NO-based therapy for clinical applications is still restricted due to its gaseous state and short half-life.Here we exploited a wound dressing by incorporating sodium nitroprusside doped prussian blue nanoparticals and Type I collagen into the chitosan/poly(vinyl alcohol)nanofibers through the electrospinning method.This hybrid nanofibrous scaffold possess the excellent abilities of NIR controlled NO release,photothermal therapy,and imitation of extra-cellular matrix-like architecture.These synergistic effects could enhance their anti-bactericidal effects in vitro and furthermore accelerate wound healing in vivo when compared to control groups.Histological analysis demonstrated the scaffold could promote fibroblast growth and accelerate epithelialization.Moreover,no apparent histological toxicology and negligible damage to major organs were observed,which provided sufficient biosafety for in vivo application.These data indicate the fabricated hybrid nanofibrous scaffold could be used as an ideal candidate for accelerating wound healing and treating chronic wounds. | Wenyu Wang Dejun Ding Kunpeng Zhou Man Zhang Weifen Zhang Fang Yan Ni Cheng | 2021 | Journal of Materials Science & Technology2021，，34： | 1 |
| 3 | The importance of proleptic branch traits in biomass production of poplar in high-density plantations显示文摘Branch phenotypic traits determine tree crown architecture,which in turn governs leaf display,light interception,and biomass production.Sylleptic and proleptic branches are the obviously different branch phenotypes in the poplar crown.Many studies have focused on the influence of sylleptic branch numbers(SBN)on biomass production,but the research on the influence of proleptic branch phenotypes was only a few.To explore the relationship between proleptic branch traits and biomass generation production in a high-density poplar plantation,we investigated the branch phenotypic traits of three poplar genotypes,all of which have high survival rates in forests(>95%)and significantly different crown architecture and biomass performance in the high-density plantations(1667 stems ha−1).The plantation site was established in 2007.A terrestrial laser scanner was used to measure branch characteristics such as length,angle of origin and termination,and azi-muth angle.A hierarchical cluster analysis performed on branch characteristics showed that SBN,crown depth,and proleptic branch curvature(PBC)were clustered with bio-mass production and leaf area index(LAI).Among all of the monitored traits,PBC played the second most important role in biomass production after SBN and was significantly correlated with SBN,LAI,and biomass production.The positive correlation between PBC and SBN indicated that a larger PBC was associated with more sylleptic branches within the monitored genotypes planted in the high-density plantation,providing greater leaf area and biomass produc-tion.The results of this study will improve the identification of high-production poplar varieties for cultivation in high-density plantations for biofuel production. | Changjun Ding Ningning Wang Qinjun Huang Weixi Zhang Juan Huang Suli Yan Boyi Chen Dejun Liang Yufeng Dong Yingbai Shen Xiaohua Su | 2022 | Journal of Forestry Research2022，33，2： | 1 |

| 5 | Electrolyte induced synergistic construction of cathode electrolyte interphase and capture of reactive free radicals for safer high energy density lithium-ion battery显示文摘As the energy density of battery increases rapidly,lithium-ion batteries(LIBs)are facing serious safety issue with thermal runaway,which largely limits the large-scale applications of high-energy-density LIBs.It is generally agreed that the chemical crosstalk between the cathode and anode leads to thermal runaway of LIBs.Herein,a multifunctional high safety electrolyte is designed with synergistic construction of cathode electrolyte interphase and capture of reactive free radicals to limit the intrinsic pathway of thermal runaway.The cathode electrolyte interphase not only resists the gas attack from the anode but suppresses the parasitic side reactions induced by electrolyte.And the function of free radical capture has the ability of reducing heat release from thermal runaway of battery.The dual strategy improves the intrinsic safety of battery prominently that the triggering temperature of thermal runaway is increased by 24.4℃and the maximum temperature is reduced by 177.7℃.Simultaneously,the thermal runaway propagation in module can be self-quenched.Moreover,the electrolyte design balances the trade-off of electrochemical and safety performance of high-energy batteries.The capacity retention of LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)|graphite pouch cell has been significantly increased from 53.85%to 97.05%with higher coulombic efficiency of 99.94%at operating voltage extended up to 4.5 V for 200 cycles.Therefore,this work suggests a feasible strategy to mitigate the safety risk of high-energy-density LIBs without sacrificing electrochemical performances. | Mengfei Ding Xuning Feng Yong Peng Jing Jing Tong Bowen Hou Yalan Xing Weifeng Zhang Li Wang Yu Wu Jiabin Lv Chunyan Luo Dejun Xiong Shichao Zhang Minggao Ouyang | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 6 | Surface Modification of Medical Polyurethane by Plasma Treatment显示文摘The wettability and surface structure of plasma treatment on medical polyurethane were studied.Two kinds of gas,N_(2),Ar,were used to create the dow-temperature plasma under low pressure.The wettability was investigated by means of the sessile drop method using water,the results show that the contact angle of water decreases from 78.8°to 61.9°as the treatment time increases.The results of electron spectroscopy for chemical analysis indicate that original chemical bonds were broken up after plasma,treatment,which was the main reason for the surface modificatioii.At same time,the results of electron spinning resonance show that the amounts of radicals did not increase significantly after treatment,which is advantageous to clinical practice of polyurethane. | LI Dejun ZHAO Jie GU Hanqing LU Mozhu DING Fuqing HU Jianfang | 1992 | Chinese Physics Letters1992，9，2： | 0 |
