1Oil filling history of the Bashituo Oilfield in the Markit Slope,SW Tarim Basin,China显示文摘The Markit Slope is an important area for the petroleum exploration in the Tarim Basin. Elucidation of the oil filling history of discovered oilfields has great significance for recognizing the accumulation processes of the whole region. Using molecular geochemistry, fluid inclusion techniques and basin modeling, we studied the oil filling process of the Bashituo Oilfield that is located in the west of the Markit Slope. The molecular migration indexes, such as the methyldibenzothiophene ratio (4-/1-MDBT), trimethylnaphthalene ratio (TMNr) and pyrrolic nitrogen compounds content, decrease from west to east, indicating that the charging direction and migration pathways are from west to east. Lithological analysis and homogenization temperatures of saline fluid inclusions accompanied with oil fluid inclusions suggest that two charging periods occurred in the Devonian oil reservoir. Combining the burial history and heating history of well BT4, Basinmod 1D software modeling shows the two oil filling periods are from 290 Ma to 285 Ma and from 10 Ma to 4 Ma, respectively, and later oil filling dominates. This study may be helpful to understand the accumulation process and provide useful references for oil and gas exploration in the Markit Slope.Cui Jingwei Wang Tieguan Li Meijun Ou Guangxi Geng Feng Hu Jian 2013Petroleum Science2013,10,1:11
2Cancer metabolism and tumor microenvironment:fostering each other?显示文摘The changes associated with malignancy are not only in cancer cells but also in environment in which cancer cells live.Metabolic reprogramming supports tumor cells’high demand of biogenesis for their rapid proliferation,and helps tumor cells to survive under certain genetic or environmental stresses.Emerging evidence suggests that metabolic alteration is ultimately and tightly associated with genetic changes,in particular the dysregulation of key oncogenic and tumor suppressive signaling pathways.Cancer cells activate HIF signaling even in the presence of oxygen and in the absence of growth factor stimulation.This cancer metabolic phenotype,described firstly by German physiologist Otto Warburg,ensures enhanced glycolytic metabolism for the biosynthesis of macromolecules.The conception of metabolite signaling,i.e.,metabolites are regulators of cell signaling,provides novel insights into how reactive oxygen species(ROS)and other metabolites deregulation may regulate redox homeostasis,epigenetics,and proliferation of cancer cells.Moreover,the unveiling of noncanonical functions of metabolic enzymes,such as the moonlighting functions of phosphoglycerate kinase 1(PGK1),reassures the importance of metabolism in cancer development.The metabolic,microRNAs,and ncRNAs alterations in cancer cells can be sorted and delivered either to intercellular matrix or to cancer adjacent cells to shape cancer microenvironment via media such as exosome.Among them,cancer microenvironmental cells are immune cells which exert profound effects on cancer cells.Understanding of all these processes is a prerequisite for the development of a more effective strategy to contain cancers.Yiyuan Yuan Huimin Li Wang Pu Leilei Chen Dong Guo Hongfei Jiang Bo He Siyuan Qin Kui Wang Na Li Jingwei Feng Jing Wen Shipeng Cheng Yaguang Zhang Weiwei Yang Dan Ye Zhimin Lu Canhua Huang Jun Mei Hua-Feng Zhang Ping Gao Peng Jiang Shicheng Su Bing Sun Shi-Min Zhao 2022Science China(Life Sciences)2022,65,2:5
3Design and baseline data of a populationbased metabonomics study of eye diseases in eastern China: the Yueqing Ocular Diseases Investigation显示文摘Background:China is undergoing a massive transition toward an urban and industrial economy.These changes will restructure the demographics and economy which will eventually influence the future patterns of disease.The risk factors of vision-impairing eye diseases remain ambiguous and poorly understood.Metabolomics is an ideal tool to understand and shed light on the ocular disease mechanisms for earlier treatment.This article aims to describe the design,methodology and baseline data of the Yueqing Ocular Diseases Investigation(YODI),a developed county population-based study to determine the prevalence and primary causes of visual impairment;also with metabonomics analysis we aimed to identify,predict and suggest some preventive biomarkers that cause blindness.Methods:A population-based,cross-sectional study.Randomized clustering sampling was used to identify adults aged 50 years and older in Xiangyang Town,Yueqing county-level City.The interviews covered demographic,behavioral,ocular risk factors and mental health state.The ocular examination included visual acuity,autorefraction,intraocular pressure,anterior and posterior segment examinations,fundus photography,retinal tomography and angiography,and visual field testing.Anthropometric measurements included height and weight,waist and hip circumference,blood pressure,pulse rate,electrocardiogram,and abdominal ultrasound scan.A venous blood sample was collected for laboratory tests and metabonomics studies.Results:Of the 5319 individuals recruited for the YODI,4769(89.7%)subjects were enrolled for analyses.The median age was 62.0 years,and 45.6%were male.The educational level of illiteracy or semi-illiteracy,primary,middle and high school or above was 29.8%,45.5%,20.1%,and 3.3%,respectively.Majority of the participants were female,younger,and less educated when compared with nonparticipants.The average body mass index and waist-hip ratios were 24.4±3.4 kg/m^(2) and 0.9±0.1 respectively.Blood sample collection reached a sample size of 1909(479 from subjects with selfreported diabetes and 1430 from one-third of the 4290 subjects without self-reported diabetes).Conclusions:The YODI provides population-based data with a high response rate(89.7%)on the prevalence and primary causes of major vision-impairing eye diseases in developed county areas in eastern China.Metabonomics analysis from YODI will provide further association of metabolic characteristics with the visual impairment eye diseases.The risk prediction model could be created and has the potential to be generalized to developed eastern areas in China for prevention.Yuxuan Deng Yuanbo Liang Sigeng Lin Liang Wen Jin Li Yue Zhou Meixiao Shen Jingwei Zheng Kemi Feng Yanting Sun Kwapong Willaim Robert Jia Qu Fan Lu 2020Eye and Vision2020,7,1:4
4A versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxide and oxide nanospheres as catalytic reactors显示文摘Nowadays,multi-shelled mesoporous hollow metal oxide nanospheres have drawn a lot of attention due to their large internal space,nanometer scaled shell thickness,high specific surface area and well-defined mesopores,of which unique nanostructure endows metallic oxides with enhanced properties.In this thesis,we have studied and proposed a versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxides and oxides nanospheres,in which silica nanospheres act as sacrificial templates and the coordination interaction between metal ions and surfactant can be cooperatively amplified by using chelating ligand(ascorbic acid)as a co-template.The synthesized metal hydroxides and oxides nanospheres possess stable hollow structure,uniform spherical morphology and tunable diameter from 270 to 690 nm.All the multi-shelled mesoporous hollow metal hydroxide and metal oxide nanospheres exhibit high surface areas(up to 640 m^(2)/g).The obtained Au nanoparticles loaded composited nanospheres exhibit excellent reactivity for solvent-free aerobic oxidation of ethylbenzene with high activity(28.2%)and selectivity(87%).Jingwei Liu Yali Ma Liangliang Zhang Yuenan Zheng Rui Zhang Ling Zhang Feng Wei Zhen-An Qiao 2021Nano Research2021,14,9:2
5A novel TiO_2 with a large amount of bulk intrinsic defects-Visible-light-responded photocatalytic activity induced by foreign trap显示文摘A novel TiO2 (anatase) containing a large amount of single electron trapped oxygen vacancies (SETOV) was prepared by dehydration of titanic acid nanotubes. This novel TiO2 contains high concentration intrinsic defects in bulk structure, while its surface still remains the stoichiometric structure to protect them. And this novel TiO2 itself has the visible light absorption without any doping, so we call it as the third generation of TiO2 . However, it is regretted that this novel TiO2 (A) only has photocatalytic activity under UV light irradiation, and was inactive for the visible light. The true reasons for this phenomenon were investigated by the transient IR absorption and photoluminescence spectra. Through constructing the foreign electron traps (PdO, PtO2 ), the photocatalytic oxidation of propylene under visible light irradiation was successfully achieved. The removal yield of propylene (C3H6 ) reached 7.6% and 28% on 2 wt.% PtO2 /novel TiO2 and 2 wt.% PdO/novel TiO2 , respectively. By comparison with the noble metal electron traps (Pt, Pd), we found that the effective foreign electron traps need to satisfy two conditions: (1) its work function should situate in the range of Eg(TiO2 ); (2) O2 adsorbes on it undissociatively. This work opens up a new route for the investiga- tion of solar-energy-available TiO2 .LI QiuYe ZHANG JiWei JIN ZhenSheng FENG CaiXia ZHANG JingWei WU ZhiShen ZHANG ZhiJun 2013Chinese Science Bulletin2013,58,14:1

17Microstructure and Properties of Plasma Spraying Boron Carbide Coating显示文摘Microstructure of plasma spray boron carbide coating was studied by SEM and TEM. its physical, mechanical and electrical properties were measured. The results showed that high microhardness. modulus and low porosity of B4C coating were manufactured by plasma spray. It was lamellar packing and dense. The B4C coating examined here contained two principal structures and two impurity phase besides major phase. The relatively small value of Young’s modulus, comparing with that of the bulk materials, is explained by porosity. The Fe impurity phase could account for the relatively high electrical conductivity of boron carbide coating by comparing with the general boron carbide materials.Yi ZENG, Jingwei FENG and Chuanxian DING (Shanghai Institute of Ceramics, Chinese Academy of Sciences, 1295 Dingxi Road, Shanghai 200050, China) 2000Journal of Materials Science & Technology2000,16,1:1
