| 1 | The Cretaceous tectonic event in the Qiangtang Basin and its implications for hydrocarbon accumulation显示文摘The tectonic event during Cretaceous and its relationship with hydrocarbon accumulation in the Qiangtang Basin is discussed based on zircon U-Pb dating and the study of deformation, thermochronology and hydrocarbon formation. LA-ICPMS zircon U-Pb dating indicates that the tectonic event took place during the Early-Late Cretaceous (125-75Ma). The event not only established the framework and the styles of structural traps in the basin, but also led to the cessation of the first hydrocarbon formation and the destruction of previous oil pools. The light crude oil in the basin was formed during the second hydrocarbon formation stage in the Cenozoic, and ancient structural traps formed during the Cretaceous event are promising targets for oil and gas exploration. | Li Yalin Wang Chengshan Li Yongtie Ma Chao Wang Licheng Peng Shaonan | 2010 | Petroleum Science2010，7，4： | 11 |
| 2 | Highly stable Al-doped ZnO by ligand-free synthesis as general thickness-insensitive interlayers for organic solar cells显示文摘Highly conductive and dispersible Al-doped ZnO(AZO) nanoparticles(NPs) have been successfully prepared by ligand-free colloidal synthesis at low temperature and stabilization by surfactant-aid including ethanolamine(EA), ethylenediamine(EDA),diethylenetriamine(DETA) and triethylenetetramine(TETA). Due to the strong intermolecular hydrogen-bonding interactions between AZO NPs and the amino groups from surfactants, the inevitable aggregation was suppressed and the surface defect sites were passivated obviously. The existence of electron transfer from the nitrogen of the amino groups to the zinc of AZO,led to a dramatic increase in electrical conductivity. A homogeneous current intensity value up to ~2200 pA for AZO tread by DETA was characterized by conductive atomic force microscopy(C-AFM), which was more superior than that of the reported sol-gel synthesized AZO with the assistance of EA surfactant(refer to 170.7 pA). Furthermore, non-fullerenes solar cells based on PBDB-T:ITIC with AZO-DETA(80 nm) yielded a best device efficiency of 10.7% and kept up prominent PCE exceeding 10%even with more thicker interlayer(95 nm). | Yilin Wang Zhongyou Peng Shuqin Xiao Jia Yang Huanyu Zhou Liqiang Huang Lulu Sun Yinhua Zhou Licheng Tan Yiwang Chen | 2018 | Science China Chemistry2018，61，1： | 2 |
| 3 | Dynamic Analysis of Bubble Attachment and Sweeping on Microwire in Subcooled Nucleate Pool Boiling显示文摘With the development of industrial technology,heat transfer at the microscale has attracted more and more attention.In this work,200μm platinum wire and 150μm nickel-chromium wire were used as experimental objects,which the power was provided by DC power with the range of 15.6 W to 56.2 W.Distilled water was used as the experimental liquid.Various bubbles on the micro wire were observed and the heat mechanism was analyzed.A variety of bubble attachment phenomena were captured on the 200μm platinum wire,including the adhesion during bubble detachment,the rotation of small attached bubbles on the surface of large bubble,multiple bubbles circling at the top of the same bubble,and different attached bubble departure phenomena.Marangoni force in the vertical direction triggered the formation of bubble attachment.In addition,the effects of surface tension,adhesion force and buoyancy force on the circling of the bubble were also considered.The analysis of the bubble sweeping on the 150μm nickel-chromium wire was analyzed.The results showed that the static bubble would interact with the sweeping bubbles on the other side,thereby changing the heat transfer mechanism,which was not discussed in detail before.The bubble jet flow generated by thermocapillary convection on the vertical direction of the bubble surface was the main influencing factor,which would change the microlayer encountered in front of the bubble.The effects of bubble diameter and liquid subcooling on the sweeping velocity were also studied.The results showed that the larger the bubble diameter was,the lower the sweeping velocity would be achieved while the liquid subcooling temperature had less impact on the velocity of sweeping bubble. | XU Nian JIANG Hantao PENG Licheng WANG Dongdong CHU Huaqiang | 2021 | Journal of Thermal Science2021，30，5： | 0 |
| 4 | Assessment of soil total phosphorus storage in a complex topography along China's southeast coast based on multiple mapping scales显示文摘Soil phosphorus (P) plays a vital role in both ecological and agricultural ecosystems, where total P (TP) in soil serves as a crucial indicator of soil fertility and quality. Most of the studies covered in the literature employ a single or narrow range of soil databases, which largely overlooks the impact of utilizing multiple mapping scales in estimating soil TP, especially in hilly topographies. In this study, Fujian Province, a subtropical hilly region along China’s southeast coast covered by a complex topographic environment, was taken as a case study. The influence of the mapping scale on soil TP storage (TPS)estimation was analyzed using six digital soil databases that were derived from 3 082 unique soil profiles at different mapping scales, i.e., 1:50 000 (S5),1:200 000 (S20), 1:500 000 (S50), 1:1 000 000 (S100), 1:4 000 000 (S400), and 1:10 000 000 (S1000). The regional TPS in the surface soil (0–20 cm) based on the S5, S20, S50, S100, S400, and S1000 soil maps was 20.72, 22.17, 23.06, 23.05, 22.04, and 23.48 Tg, respectively, and the corresponding TPS at0–100 cm soil depth was 80.98, 80.71, 85.00, 84.03, 82.96, and 86.72 Tg, respectively. By comparing soil TPS in the S20 to S1000 maps to that in the S5map, the relative deviations were 6.37%–13.32%for 0–20 cm and 0.33%–7.09%for 0–100 cm. Moreover, since the S20 map had the lowest relative deviation among different mapping scales as compared to S5, it could provide additional soil information and a richer soil environment than other smaller mapping scales. Our results also revealed that many uncertainties in soil TPS estimation originated from the lack of detailed soil information, i.e., representation and spatial variations among different soil types. From the time and labor perspectives, our work provides useful guidelines to identify the appropriate mapping scale for estimating regional soil TPS in areas like Fujian Province in subtropical China or other places with similar complex topographies. Moreover, it is of tremendous importance to accurately estimate soil TPS to ensure ecosystem stability and sustainable agricultural development, especially for regional decision-making and management of phosphate fertilizer application amounts. | Zhongxing CHEN Jing LI Kai HUANG Miaomiao WEN Qianlai ZHUANG Licheng LIU Peng ZHU Zhenong JIN Shihe XING Liming ZHANG | 2024 | Pedosphere2024，34，1： | 0 |
