| 1 | Trends in the Different Grades of Precipitation over South China during 1960–2010 and the Possible Link with Anthropogenic Aerosols显示文摘Using observed daily precipitation data to classify five levels of rainy days by strength in South China(SC), with an emphasis on the Pearl River Delta(PRD) region, the spatiotemporal variation of different grades of precipitation during the period 1960–2010 was analyzed and the possible link with anthropogenic aerosols examined. Statistical analysis showed that drizzle and small precipitation has significantly decreased, whereas medium to heavy precipitation has increased slightly over the past 50 years(although not statistically significant). Further data analysis suggested that the decline in drizzle and small precipitation probably has a strong link to increased concentrations of anthropogenic aerosols produced by large-scale human activities related to the rapid socioeconomic development of the PRD region. These aerosols may also have led to the obvious decreasing trend in horizontal visibility and sunshine duration in SC, which is statistically significant according to the t-test. | FU Chuanbo DAN Li | 2014 | Advances in Atmospheric Sciences2014，31，2： | 9 |
| 2 | Trends of the sunshine duration and diffuse radiation percentage on sunny days in urban agglomerations of China during 1960–2005显示文摘The long-term observational data of sunshine duration(SD) and diffuse radiation percentage(defined as diffuse solar radiation/total solar radiation, DRP) on sunny days during 1960–2005 were analyzed in 7 urban agglomerations and the whole of China. The results show that the sunny sunshine duration(SSD) has decreased significantly except at a few stations over northwestern China in the past 46 years. An obvious decrease of the SSD is found in eastern China, with the trend coefficients lower than-0.8. Accompanied by the SSD decline, the sunny diffuse radiation percentage(SDRP) in most stations shows obvious increasing trends during the 46 years. The averaged SDRP over China has increased 2.33%per decade, while the averaged SSD shows a decrease of-0.13 hr/day per decade. The correlation coefficient between SDRP and SSD is-0.88. SSD decreased over urban agglomerations(small to large city clusters) in the past 46 years, especially in large cities and medium cities, due to the strong anthropogenic activities and air pollution represented by aerosol option depth(AOD) and tropospheric column NO2(Tro NO2). On the regional scale, SSD has an opposite trend from SDRP during 1960 to 2005, and the variation trends of regional mean values of SSD and SDRP in southeastern China are more pronounced than those in northwestern China. | Chuanbo Fu Li Dan Youlong Chen Jiaxiang Tang | 2015 | Journal of Environmental Sciences2015，27，8： | 5 |
| 3 | Post-Orogenic Tectonic Evolution of the Jiangnan-Xuefeng Orogenic Belt:Insights from Multiple Geochronometric Dating of the Mufushan Massif,South China显示文摘The Mufushan massif, as continental intra-plate magmatites located in the Jiangnan-Xuefeng orogenic belt of the South China. The Mufushan massif constitutes the largest Mesozoic intrusive complex, intruded the Mesoproterozoic Lengjiaxi Formation. Multiple geochronometric dating was used to reconstruct their evolution from emplacement to exhumation. The Mufushan granitoids were emplaced at ~150 Ma(U-Pb zircon) as post-orogenic magmatites contributing to Triassic crustal thickening. Onset of regional extension at ~128 Ma(40Ar/39Ar white mica and biotite) manifests a tectonic regime switch. Intense exhumation prior to ~55 Ma was followed by slow denudation and peneplanation for the next 37 Ma(~55–18 Ma). Accelerated cooling since ~18 Ma may have been caused by a far-field effect of the collision between IndiaAsia Plate or the Pacific-Plate subduction. Through a multi-geochronometric approach, this study provides a new comprehensive model for the cause of the intra-plate magmatism formation in the South China, and also established a reliable geochronological framework of the post-orogenic tectonic evolutions of the Jiangnan-Xuefeng orogenic belt. | Chuanbo Shen Di Hu Kyoungwon Min Chaoqun Yang Xiaowei Zeng Hongyang Fu Xiang Ge | 2020 | Journal of Earth Science2020，31，5： | 4 |

| 7 | High-gravity technology intensified Knoevenagel condensation-Michael addition polymerization of poly (ethylene glycol)-poly (n-butyl cyanoacrylate) for blood-brain barrier delivery显示文摘Poly(ethylene glycol)-poly(n-butyl cyanoacrylate)(PEG-PBCA)is a remarkable drug delivery carrier for permeating blood-brain barrier.In this work,a novel high-gravity procedure was reported to intensify Knoevenagel condensation-Michael addition polymerization of PEG-PBCA.A series of PEG-PBCA containing different block ratios were synthesized with narrow molecular weight distribution of polydispersity indexes less than 1.1.Furthermore,the reaction time reduced 60%compared to conventional stirred tank reactor process.Chemical structures of as-prepared polymers were characterized.In vitro drug delivery performance was evaluated.The cytotoxicity of PEG-PBCA to brain microvessel endothelial cells(BMVEC)decreases with the extension of the PEG chain and the shortening of the PBCA chain.The polymer cellular uptake to BMVECs was better after improving hydrophilicity by PEG block.Results of bloodbrain barrier permeability demonstrated that medium length of PBCA chain and short PEG chain are favorable for hydrophobic Nile red permeation,while long PEG chain and short PBCA chain are beneficial to delivery water-soluble doxorubicin hydrochloride(Dox).The average apparent permeability coeffi-cient increased 1.7 and 0.25 times than that of raw Nile red and Dox,respectively.High-gravity intensi-fied condensation polymerization should have great potential in brain drug delivery system. | Xingzheng Liu Chuanbo Fu Manting Wang Jiexin Wang Haikui Zou Yuan Le Jianfeng Chen | 2022 | Chinese Journal of Chemical Engineering2022，35，6： | 0 |
