1Warm-Season Diurnal Variations of Total, Stratiform, Convective, and Extreme Hourly Precipitation over Central and Eastern China显示文摘Diurnal variations in amount, frequency and intensity of warm-season hourly precipitation(HP) at seven levels, which are defined as HP 0.1, 0.5, 1, 5, 10, 20 and 50 mm, are revealed based on no less than 30 years of hourly rain-gauge observations at national stations over central and eastern China(CEC). This study investigates the variations, relationships, differences and similarities of total, stratiform, convective and extreme HP over the entire CEC and various subregions. Results indicate that the variations in the amount and frequency of HP at the seven levels over the entire CEC all display a bimodal feature. For various regions, the variations of total HP mostly feature two peaks, while convective HP mainly occurs in the late afternoon and determines the diurnal variation of total HP intensity. On the basis of the primary peak time periods of HP frequency at all levels over different subregions, the variations can be classified into three main categories: late-afternoon primary peak, nocturnal primary peak, and time-shifting primary peak. However, the variations over some coastal regions like the Liaodong Peninsula, the Shandong Peninsula, and the coastal regions of Guangdong, distinctly differ from those over their corresponding larger regions. Overall, the normalized diurnal variation amplitude of amount and frequency increases with the increasing HP intensity; convective precipitation can be represented by HP 10 mm; and the intensity of HP 50 mm is slightly larger during the nighttime than during the daytime over the entire CEC. In northern China, diurnal variation in HP 5 mm can represent well that in convective precipitation.Yongguang ZHENG Yanduo GONG Jiong CHEN Fuyou TIAN 2019Advances in Atmospheric Sciences2019,36,2:6
2Hyperterpenoids A and B:Two pairs of unprecedented 6/6/4/6/6 polycyclic cyclobutane meroterpenoids with potent neuroprotective and anti-inflammatory activities from Hypericum beanii显示文摘Hyperterpenoid A(1)and B(2),two pairs of enantiomers,with an unprecedented 6/6/4/6/6 polycyclic skeleton,along with one known compoud hypermonone A(3)were isolated from Hypericum beanii.The racemate(±)-1 and(±)-2 were successfully separated into the two optically pure enantiomers(ee>99%)using a preparative HPLC system.Their absolute configurations were elucidated by extensive spectroscopic analyses and single-crystal X-ray diffraction method.The related plausible biogenetic pathways were pre sented.Compound 1-3 showed significant neuroprotective activity and potential antiinflammatory activity.The result that(+)-2 and(-)-2 presented different anti-inflammatory properties,may lead us to new discovery of structure activity relationship between racemates,enantiomers,and diastereomers,as well as further research regarding the binding of drugs to target proteins.Bo Zhen Xinyue Suo Jun Dang Huilan Yue Yanduo Tao Jia-Jia Wang Li Li Ming-Bao Lin Qi Hou Wei-Ping Wang Xiao-Liang Wang Jian-Dong Jiang Teng-Fei Ji 2021Chinese Chemical Letters2021,32,7:2

8Highly Efficient and Selective Photocatalytic Nonoxidative Coupling of Methane to Ethylene over Pd-Zn Synergistic Catalytic Sites显示文摘Photocatalytic nonoxidative coupling of CH_(4)to multicarbon(C^(2+))hydrocarbons(e.g.,C,H4)and H,under ambient conditions provides a promising energy-conserving approach for utilization of carbon resource.However,as the methyl intermediates prefer to undergo self-coupling to produce ethane,it is a challenging task to control the selective conversion of CH to higher valueadded CH4.Herein,we adopt a synergistic catalysis strategy by integrating Pd-Zn active sites on visible light-responsive defective WO_(3)nanosheets for synergizing the adsorption,activation,and dehydrogenation processes in CH_(4)to C_(2)H_(4)conversion.Benefiting from the synergy,our model catalyst achieves a remarkable C^(2+)compounds yield of 31.85μmolgh with an exceptionally high C,H4 selectivity of 75.3%and a stoichiometric H_(2)evolution.In situ spectroscopic studies reveal that the Zn sites promote the adsorption and activation of CH_(4)molecules to generate methyl and methoxy intermediates with the assistance of lattice oxygen,while the Pd sites facilitate the dehydrogenation of methoxy to methylene radicals for producing C_(2)H_(4)and suppress overoxidation.This work demonstrates a strategy for designing efficient photocatalysts toward selective coupling of CH_(4)to higher value-added chemicals and highlights the importance of synergistic active sites to the synergy of key steps in catalytic reactions.Yanduo Liu Yihong Chen Wenbin Jiang Tingting Kong Pedro H.C.Camargo Chao Gao Yujie Xiong 2023Research2023,,1:0
