| 1 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020，63，8： | 7 |
| 2 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017，62，21： | 6 |
| 3 | Blue LED-pumped intense short-wave infrared luminescence based on Cr^(3+)-Yb^(3+)-co-doped phosphors显示文摘The growing demand for spectroscopy applications in the areas of agriculture,retail and healthcare has led to extensive research on infrared light sources.The ability of phosphors to absorb blue light from commercial LED and convert the excitation energy into long-wavelength infrared luminescence is crucial for the design of cost-effective and high-performance phosphor-converted infrared LEDs.However,the lack of ideal blue-pumped short-wave infrared(SWIR)phosphors with an emission peak longer than 900 nm greatly limits the development of SWIR LEDs using light converter technology.Here we have developed a series of SWIR-emitting materials with high luminescence efficiency and excellent thermal stability by co-doping Cr^(3+)-Yb^(3+) ion pairs into Lu_(0.2)Sc_(0.8)BO_(3) host materials.Benefitting from strong light absorption of Cr^(3+) in the blue waveband and very efficient Cr^(3+)→Yb^(3+) energy transfer,the as-synthesized Lu_(0.2)Sc_(0.8)BO_(3):Cr^(3+),Yb^(3+) phosphor emits intense SWIR light in the 900-1200 nm from Yb^(3+) under excitation with blue light at~460 nm.The optimized phosphor presents an internal quantum yield of 73.6%and the SWIR luminescence intensity at 100℃can still keep 88.4%of the starting value at 25℃.SWIR LED prototype device based on Lu0.2Sc0.8BO3∶Cr^(3+)Yb^(3+) phosphor exhibits exceptional luminescence performance,delivering SWIR radiant power of 18.4 mW with 9.3%of blue-to-SWIR power conversion efficiency and 5.0%of electricity-to-SWIR light energy conversion efficiency at 120 mA driving current.Moreover,under the illumination of high-power SWIR LED,covert information identification and night vision lighting have been realized,demonstrating a very bright prospect for practical applications. | Yan Zhang Shihai Miao Yanjie Liang Chao Liang Dongxun Chen Xihui Shan Kangning Sun Xiao-Jun Wang | 2022 | Light(Science & Applications)2022，11，6： | 3 |
| 4 | Establishing Gene Delivery Systems Based on Small-Sized Chitosan Nanoparticles显示文摘Chitosan is a natural cationic polysaccharide,which is often used for preparing biomedical materials because of its high biocompatibility.In this study,chitosan with a molecular weight of 160 k Da was chosen to prepare chitosan nanoparticles(CSNPs) as gene vectors by ionic cross-linking with tripolyphosphate(TPP).CSNPs were characterized in terms of particle size,zeta potential,and polydispersity index(PDI) using a Zetasizer,and morphology was evaluated by transmission electron microscopy(TEM).Furthermore,the cytotoxicity and biocompatibility of CSNPs were correspondingly examined by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay and histological examination.Agarose gel electrophoresis and UV spectrophotometric methods were performed to measure the loading capacity.The cell transfection efficiency of CSNPs loaded with plasmids or si RNA was analyzed by fluorescence microscopy or laser scanning confocal microscopy.The results showed that CSNPs were prepared successfully by the ionic gelation method,which had a smaller particle size(100 nm-200 nm),stable dispersibility,low cytotoxicity,good tissue-biocompatibility,and high gene-loading efficiency.These CSNPs could transfer the plasmids or si RNA to cells.However,CSNPs might have a much higher transfection efficiency for si RNAs than for plasmids,which implies that CSNPs might be a safer and more efficient vector for delivering si RNAs rather than plasmids. | WANG Liping ZHANG Wenhua ZHOU Quan LIU Shihai XU Wenhua SUN Teng LIANG Ye | 2018 | Journal of Ocean University of China2018，17，5： | 2 |
| 5 | Comparative proteomics analyses of intraspecific differences in the response of Stipa purpurea to drought显示文摘Stipa purpurea is widely distributed along a large precipitation gradient on the Tibetan Plateau.This implies that S.purpurea from different populations may have different responses to drought stress.To explore this we compared the morphological and physiological changes of S.purpurea seedlings cultivated from seeds from Gar County and Nagqu County after 7 and 14 days of drought stress and subsequent rewatering.The results showed that S.purpurea plants from the more arid Gar area were more tolerant to drought stress than that from Nagqu.To investigate the potential mechanisms underlying this difference,we used i TRAQ quantitative proteomics technology to analyze protein dynamics in S.purpurea samples treated with 7 days of drought stress and subsequent re-watering.The results indicated that,during the process of drought and re-watering treatments,there were differentially expressed proteins in either or both S.purpurea populations.These differential proteins were divided into 24 functional categories that were mainly associated with stress response,the antioxidant system,photosynthesis,carbohydrate metabolism,and post-translational modifications.According to these results,we concluded that the molecular basis of stronger drought resistance likely lies in the specific up-regulation or higher expression of many proteins involved in stress response,the antioxidant system,post-translational modification and osmotic regulation in S.purpurea from Gar County compared with that from Nagqu.This study improves our understanding of the intraspecific differences in drought resistance within S.purpurea populations,which helps to understand the distribution of S.purpurea along the moisture gradient,as well as the effect of climate change on this species. | Xiong Li Yunqiang Yang Shihai Yang Xudong Sun Xin Yin Youjie Zhao Yongping Yang | 2016 | 植物分类与资源学报2016，38，2： | 2 |

| 11 | Improving the intrinsic electronic conductivity of NiMo0_(4) anodes by phosphorous doping for high lithium storage显示文摘Heteroatom doping is one of the most promising strategies toward regulating intrinsically sluggish electronic conductivity and kinetic reaction of transition metal oxides for enhancing their lithium storage.Herein,we designed phosphorus-doped NiMo0_(4) nanorods(P-NiMo0_(4))by using a facile hydrothermal method and subsequent low-temperature phosphorization treatment.Phosphorus doping played an indispensable role in significantly improving electronic conductivity and the Li+diffusion kinetics of NiMo0_(4) materials.Experimental investigation and density functional theory calculation demonstrated that phosphorus doping can expand the interplanar spacing and alter electronic structures of NiMo0_(4) nanorods.Meanwhile,the introduced phosphorus dopant can generate some oxygen vacancies on the surface of NiMo0_(4),which can accelerate Li+diffusion kinetics and provide more active site for lithium storage.As excepted,P-NiMo0_(4) electrode delivered a high specific capacity(1,130 mA·g^(-1) at 100 mA·g^(-1) after 100 cycles),outstanding cycling durability(945 mA·g^(-1) at 500 mA·g^(-1) over 200 cycles),and impressive rate performance(640 mA·g^(-1)at 2,000mA·g^(-1))for lithium ion batteries(LIBs).This work could provide a potential strategy for improving intrinsic conductivity of transition metal oxides as high-performance anodes for LIBs. | Luchao Yue Chaoqun Ma Shihai Yan Zhenguo Wu Wenxi Zhao Qian Liu(ISl) Yonglan Luo Benhe Zhong Fang Zhang Yang Liu Abdulmohsen AN Alshehri Khalid Ahmed Alzahrani Xiaodong Guo Xuping Sun | 2022 | Nano Research2022，15，1： | 1 |
| 12 | Lewis base catalyzed ring-expansion of isatin with 2,2,2-trifluorodiazoethane(CF3CHN2):An efficient route to3-hydroxy-4-(trifluoromethyl)quinolinones显示文摘A Lewis base catalyzed ring expansion of isatin with 2,2,2-trifluorodiazoethane(CF3 CHN2)is developed.It is characterized that the merge of tetramethylethylenediamine and CF3 CHN2 generates reactive triazene intermediates,which construct substituted 3-hydroxy-4-(trifluoromethyl)quinolinones with high efficiency.Synthetic application of the procedure is broadened by 3-trifluormethylpyrazole fused3-hydroxy-4-(trifluoromethyl)quinolinone synthesis. | Shuaipeng Lv Yunfang Sun Yue Xu Shihai Yang Lei Wang | 2020 | Chinese Chemical Letters2020，31，6： | 0 |
| 13 | Highly efficient two-electron electroreduction of oxygen into hydrogen peroxide over Cu-doped TiO_(2)显示文摘Electrosynthesis of hydrogen peroxide(H2O_(2)),as a sustainable alternative to the anthraquinone oxidation method,provides the feasibility of directly generating H_(2)O_(2).Here,we report Cu-doped TiO_(2) as an efficient electrocatalyst which exhibits the excellent two-electron oxygen reduction reaction(2e-ORR)performance with respect to the pristine TiO_(2).The Cu doping results in the distortion of TiO_(2) lattice and further forms a large number of oxygen vacancies and Ti^(3+).Such Cu-doped TiO_(2) exhibits a positive onset potential about 0.79 V and high H_(2)O_(2) selectivity about 91.2%.Moreover,it also shows a larger H_(2)O_(2) yield and good stability.Density functional theory(DFT)calculations reveal that Cu dopant not only improves the electrical conductivity of pristine TiO_(2) but reduces the*OOH adsorption energy of active sites,which is beneficial to promote subsequently 2e-ORR process. | Zhiqin Deng Li Li Yuchun Ren Chaoqun Ma Jie Liang Kai Dong Qian Liu Yonglan Luo Tingshuai Li Bo Tang Yang Liu Shuyan Gao Abdullah MAsiri Shihai Yan Xuping Sun | 2022 | Nano Research2022，15，5： | 0 |
