| 1 | The improved model of estimating global whitecap coverage based on satellite data显示文摘The pro and con of whitecap parameterizations and a statistical wave breaking model are discussed. An improved model is derived by combining satellite-based parameterization and the wave breaking model. The appropriate constants for the general wave state are obtained by considering the breaking condition of the wave slope and fitting with the satellite-based parameterization. The result is close to the constants based on the whitecap data from Monahan. Comparing with satellite-based data and the original model's results, the improved model's results are consistent with satellite-based data and previous studies. The global seasonal distributions of the whitecap coverage averaged from 1998 to 2008 are presented. Spatial and seasonal features of the whitecap coverage are analyzed. | REN Danqin HUA Feng YANG Yongzeng SUN Baonan | 2016 | Acta Oceanologica Sinica2016，35，5： | 2 |
| 2 | Growing Knowledge of Stem Cells as a Novel Experimental Model in Developmental Toxicological Studies显示文摘The increasing production and extensive application of chemicals have led to their unintended release and contamination in the environment,posing a hazardous threat to wildlife and human health.Numerous studies have demonstrated that developmental toxicity could be induced by various emerging chemicals,causing abnormal embryonic and placental development,adverse pregnancy outcomes,obesity,and dysfunction of lipid metabolism in neonates.Given the currently-available experimental technology for developmental toxicological studies,an in vitro model based on stem cells showed promising performance in high-throughput screening of the early-stage developmental toxicity of emerging chemicals.In this review,the deleterious effects of environmental pollutants on stem cells were systemically assorted from the aspects of cytological dysfunction,self-renewal impairment,perturbation in embryoid body(EB)formation,and disruption of committed lineage differentiation.The toxicological data on the molecular level,including the altered expressions of gene and protein biomarkers,epigenomic regulation,and enhanced oxidative stress,were collected and summarized to provide the mechanism explanation for the link between environmental pollutant exposure and unfavorable phenotypes in stem cells.The advantage of the stem cell model in developmental toxicological studies was specifically emphasized.And the perspectives for stem cells were ultimately highlighted in the research field of environmental toxicology,especially developmental toxicology during the early stage of life. | REN Zhihua KU Tingting REN Mengyao LIANG Jiefeng NING Xia XU Hanqing REN Danqin ZHOU Qunfang SANG Nan | 2023 | Chemical Research in Chinese Universities2023，39，3： | 0 |
| 3 | Two-step preparation of carbon nanotubes/Ru02/polyindole ternary nanocomposites and their application as high-performance supercapacitors显示文摘A ternary single-walled carbon nanotubes/RuO2/polyindole(SWCNT/RuO2/PIn)nanocomposite was fabricated by the oxidation polymerization of indole on the prefabricated SWCNT/RuO2 binary nanocomposites.The nanocomposite was measured by FTIR,XRD,SEM,TEM,EDS and XPS,together with the electrochemical technique.The electrochemical results demonstrated that the symmetric supercapacitor used SWCNT/RuO2/PIn as electrodes presented 95%retention rate after 10000 cycles,superior capacitive performance of1203 F·g^-1 at1 A·g^-1,and high energy density of 33 w h·kg^-1 at 5000 W·kg^-1.The high capacitance performance of SWCNT/RuO2/PIn nanocomposite was mainly ascribed to the beneficial cooperation effect among components.This indicated that the SWCNT/RuO2/PIn nanocomposite would be a good candidate for high-performance supercapacitors. | Danhua ZHU Qianjie ZHOU Aiqin LIANG Weiqiang ZHOU Yanan CHANG Danqin LI Jing WU Guo YE Jingkun XU Yong REN | 2020 | Frontiers of Materials Science2020，14，2： | 0 |
