| 1 | Thermal camouflage based on the phasechanging material GST显示文摘Camouflage technology has attracted growing interest for many thermal applications.Previous experimental demonstrations of thermal camouflage technology have not adequately explored the ability to continuously camouflage objects either at varying background temperatures or for wide observation angles.In this study,a thermal camouflage device incorporating the phase-changing material Ge2Sb2Te5(GST)is experimentally demonstrated.It has been shown that near-perfect thermal camouflage can be continuously achieved for background temperatures ranging from 30℃ to 50℃ by tuning the emissivity of the device,which is attained by controlling the GST phase change.The thermal camouflage is robust when the observation angle is changed from 0°to 60°.This demonstration paves the way toward dynamic thermal emission control both within the scientific field and for practical applications in thermal information. | Yurui Qu Qiang Li Lu Cai Meiyan Pan Pintu Ghosh Kaikai Du Min Qiu | 2018 | Light(Science & Applications)2018，7，1： | 3 |
| 2 | A new synthesis method of (±) -deoxyschizandrin显示文摘DEOXYSCHIZANDRIN 10,isolated from Schizandra chinensis baill,exhibits anti-hepatitisvirus activity.Recently considerable interest in the synthesis of 10 has arisen from its bioactiv-ities.In this note a new highly efficient route to synthesize(±)-deoxyschizandrin is re-ported.Our synthetic strategy(outlined in scheme 1)started from gallic acid 1 in 10 stepswith the overall yield of 12%,and employed I2/NaOEt oxidative coupling reaction as a | WU Anxin, ZHAO Yurui, QIN Binchang, CHEN Ning and PAN XinfuState Key Laboratory of Applied Organic Chemistry, Department of Chemistry, Lanzhou University, Lanzhou 730000, China | 1997 | Chinese Science Bulletin1997，42，12： | 1 |
| 3 | N-doped interconnected carbon aerogels as an efficient SeS2 host for long life Na-SeS2 batteries显示文摘Selenium sulfide(SeS2)cathodes have attracted much concern as an optimized choice comparing to sulfur and selenium for lithium and sodium storage.However,it also suffers from poor cycling stability due to the dissolution of reaction intermediate products.In this study,N-doped Interconnected carbon aerogels was applied as an efficient SeS2 host by infiltrating selenium sulfide into its microporous structure(denoted as SeS2@NCAs),which could effectively accommodate the volume change of SeS2 during cycling and alleviate the dissolution of reaction intermediate products.Therefore,as for Na storage,the SeS2@NCAs cathode delivers a superior long-term cycling performance of 536 mA·h·g^-1 at a current density of 0.5 A·g^-1 after 1,000 cycles with only 0.04%capacity decline per cycle and a high rate performance(524 mA·h·g^-1 at 2 A·g^-1 and 745 mA·h·g^-1 at 0.1 A·g^-1 retained),indicating the remarkable cycling stability of SeS2@NCAs cathodes. | Yurui Deng Lunlun Gong Hoda Ahmed Yuelei Pan Xudong Cheng Siyu Zhu Heping Zhang | 2020 | Nano Research2020，13，4： | 1 |
| 4 | Synthesis and optimization of high-performance amine-based polymer for CO_(2) separation显示文摘Membrane technology features inspiring excellence from numerous separation technologies for CO_(2) capture from post-combustion gas.Polyvinylamine(PVAm)-based facilitated transport membranes show significantly high separation performance,which has been proven promising for industrial scale-up.However,commercialized PVAm with low molecular weight and excessive crystallinity is not available to prepare high-performance membranes.Herein,the synthesis process of PVAm was optimized by regulating polymerization and acidic hydrolytic conditions.The membranes based on PVAm with a molecular weight of 154 kDa and crystallinity of 11.37%display high CO_(2) permeance of 726 GPU and CO_(2)/N_(2) selectivity of 55 at a feed gas pressure of 0.50 MPa.Furthermore,we established a PVAm synthesis reactor with an annual PVAm solution(1%(mass))capacity of over 7000 kg and realized the scaled-up manufacture of both PVAm and composite membranes. | Ye Yuan Yurui Pan Menglong Sheng Guangyu Xing Ming Wang Jixiao Wang Zhi Wang | 2022 | Chinese Journal of Chemical Engineering2022，，10： | 0 |
| 5 | Spatial pattern of urban-rural integration in China and the impact of geography显示文摘Urban-rural integration (URI) is a global challenge that is highly related to inequalities, poverty, economic growth, and other Sustainable Development Goals (SDGs). Existing research has evaluated the extent of URI and explored its influencing factors, but urban-rural linkages are seldom incorporated in evaluation systems, and geographical factors are rarely recognized as the influencing factors. We construct a URI framework including regional economy, rural development, urban-rural linkage, and urban-rural gap. Based on a dataset consisting of 1,669 counties in China in 2020, we reveal the spatial pattern of URI and find a high correlation between the spatial pattern of URI and the relief degree of land surface (RDLS). Using structural equation modeling, we discover that topography has direct ( − 0.18, p < 0.001) and indirect ( − 0.17, p < 0.001) effects on URI. The indirect negative effects are mediated through the infrastructure, and the combination of localized advantages and modern technical conditions could mitigate the negative impact of topography. Finally, we identify 742 counties as lagging regions in URI, which can be clustered into eight types. Our findings could facilitate policy designing for those countries striving for integrated and sustainable development of urban and rural areas. | Wei Pan Jing Wang Yurui Li Shuting Chen Zhi Lu | 2023 | Geography and Sustainability2023，4，4： | 0 |
