1Preparation of microbial desulfurization catalysts显示文摘A Rhodococcus sp. lawq, a bacterium isolated from the soil cleaving the C-S bond of dibenzothiophene (DBT) via specific pathway, was investigated for cell growth and for its role in desulfurization. Clearly, the end product, 2-hydroxybiphenyl, inhibited the growth of the strain, the synthesis of the desulfurization enzymes, and the activity of the enzymes. The effects of sulfate on the DBT degradation enzymes were examined in the Rhodococcus sp. lawq growth system with DBT; the sulfate served, concurrently, as the sulfur source. The condition of the resting cells that were used in desulfurization, was also studied. The optimal concentration of the resting cells and the reaction conditions were determined. It was documented that there is no difference between desulfurization activity for resting cells cultured with sulfate as the sole sulfur source and that with the mixture of DBT and sulfate as the sulfur source.XU Ping MA Cuiqing LI Fuli TONG Mingyou ZENG Yiyong WANG Shuning H.D.Blankespoor 2002Chinese Science Bulletin2002,47,13:4
2Sol-gel preparation and characterization of Li_(1.3)Al_(0.3)Ti_(1.7)(PO_4)_3 sintered with flux of LiBO_2显示文摘Li1.3Al0.3Ti1.7(PO4)3 pellets sintered with different mole fractions of LiBO2 were prepared by sol-gel method.The structural identification,surface morphology,ionic conductivity,and activation energy of the pellets were studied by X-ray diffraction,scanning electron microscopy,and electrochemical impedance spectroscopy.The results show that all the Li1.3Al0.3Ti1.7(PO4)3 pellets sintered with different mole fractions of LiBO2 have similar X-ray diffraction patterns.The sintered pellet becomes denser and the boundary and corner of the particles become illegible with the increase of LiBO2.Among the Li1.3Al0.3Ti1.7(PO3)4 pellets sintered with different mole fractions of LiBO2,the one sintered with 1 mol% LiBO2 shows the highest ionic conductivity of 3.95×10-4 S.cm-1 and the lowest activation energy of 0.2469 eV.WU Xianming,LI Runxiu,CHEN Shang,HE Zeqiang,and MA Mingyou College of Chemistry and Chemical Engineering,Jishou University,Jishou 416000,China 2010Rare Metals2010,29,5:3
3State of rare earth elements in the rare earth deposits of Northwest Guizhou,China显示文摘We studied the states of rare earth elements in ore of the Xianglushan rare earth deposit. Rare earth ore samples were tested and examined by scanning electron microscope, electron probe, and chemical leaching. No independent rare earth minerals were detected by scanning electron microscope. Elements detected by the electronic probe for the in situ micro-zone of the sample included: O,Al, Si, Ca, Mg, Fe, Ti, K, Na, S, Cl, C, Cu, Cr, V, and Pt.Rare earth elements were not detected by electron probe.(NH_4)_2 SO_4,(NH_4)Cl, NaCl, and H_2 SO_4 were used as reagents in chemical leaching experiments that easily leached out rare earth elements under the action of 10%reagent, indicating that the rare earth elements in ore are mainly in the ionic state rather than present as rare earth minerals.Peinan He Mingyou He Hai Zhang 2018Acta Geochimica2018,37,6:3
4Advances in Utilization of Agricultural Waste Based on Production of Edible Fungi显示文摘Along with the rapid development of edible fungus industry in China,the traditional mode of production giving priority to wood chips will be severely limited,and using agricultural waste distributed widely,having large yield,and containing high content of organic matter to produce edible fungi has good economic and ecological benefit. In this paper,based on the analysis of characteristics of agricultural waste in China,the present situation of application of agricultural waste in the production of edible fungi at home and abroad was introduced,and the main problems existing in production of edible fungi by using agricultural waste in China at the present stage were pointed out. Finally,the development direction of using agricultural waste to cultivate edible fungi was discussed,and some suggestions were put forward,such as improving the theoretical system for using agricultural waste to produce edible fungi,and establishing the standardized technical system for using agricultural waste to produce edible fungi.Mingyou WANG Weidong SONG Jiaoling WANG Jinji WU Tianhang DING Feng LI 2017Asian Agricultural Research2017,9,6:2
5Implication of Sedimentary Facies and Shale Gas Accumulation in the Lower Silurian Longmaxi Formation,Eastern Sichuan Basin,China显示文摘1 Introduction The Lower Silurian Longmaxi Formation is the most prolific shale gas producing unit in the Sichuan Basin by the large thickness and rich resources,which also indicate a bright exploration prospect for the unconventional shale gas.Eastern Sichuan region,the relatively active high and steep structural belt between the stable massifs in Sichuan basin(Fig.1),is influenced by the factors of deepburied,intense tectonic reworking and fault development.Previous researchFENG Mingyou ZENG Zhen WANG Xingzhi ZHANG Fan LI Yizhen LI Ke 2015Acta Geologica Sinica(English Edition)2015,89,A01:2
6Optimal Groundwater Development in Coastal Aquifers Near Beihai, China显示文摘Groundwater resources occur in a multi aquifer system in the alluvial coastal plain near Beihai, China. The aquifers receive recharge from precipitation, canal and reservoir infiltration, and discharge through subterranean drainage into the sea and through artificial pumping. A quasi three dimensional finite element model has been used to simulate the spatial and temporal distribution of groundwater levels in the aquifers. Various input parameters were considered in the simulation model. A linear optimization model has been developed for groundwater development within the coastal aquifers. The objective function of the model is to maximize the total groundwater pumpage from the confined aquifer. The control of sea water intrusion is examined by the restriction of the water levels at points along the coast and of the pumping rates in coastal management cells. The response matrix used in the optimization model was generated from the simulation model by forecasting drawdown produced by pumping at a unit impulse discharge. Groundwater development can be primarily optimized by the alteration of the pumping rates of the existing wells.Zhou Xun Chen Mingyou Wan Li Department of Water Resources and Environmental Engineering, China University of Geosciences, Beijing 100083, China Wang Juping Ning Xuesheng Beihai Institute of Hydrogeology, Engineering Geology and Mineral Resour 2000Journal of Earth Science2000,19,3:2
7Ore prospecting model and targets for the Dashuigou tellurium deposit, Sichuan Province, China显示文摘The Dashuigou tellurium(Te) deposit in Shimian city, Sichuan Province is the only known independent Te ore deposit in China. Samples were collected by1/50,000 stream sediment survey and analyzed by inductively coupled plasma–mass spectrometry, X-ray fluorescence spectrometry, emission spectrometry, and atomic absorption spectroscopy. An ore prospecting model for the Dashuigou Te deposit was then established. In the Dashuigou area, bismuth(Bi), Te, and gold(Au) concentrations in stream sediment samples displayed weak-positive anomalies, while silver(Ag) displayed a weaknegative anomaly. Bi, Te, Ag, and Au anomalies are regarded as indicators of Te deposits; the greater the ratio of Te+Bi/Au+Ag, the larger the possibility of an independent tellurobismuthite deposit. The ratio calculated from our samples is 7.288. Five locations were identified for prospecting for Te minerals by this model, including the northern part of the Dashuigou Te deposit, Majiagou,Tizigou, southeastern Miaoping, and northern Baishuihe.These five regions are within the Dashuigou dome anticline, the exposed strata of which are controlled by tracing the tensile shear fracture; the metallogenic geological conditions and geochemical characteristics are the same as those of the known Dashuigou Te deposit. Already, Te–Bi veins have been found in some of these areas.Quanjiang Zhang Yingping Liu Mingyou He Jun Bai Wei Xu Cong Zhao 2018Acta Geochimica2018,37,4:2
8LiMn_2O_4 thin films derived by rapid thermal annealing and their performance as cathode materials for Li ion battery显示文摘The LiMn2O4 thin film as a cathode material was prepared through solution deposition followed by rapid thermal annealing (RTA). The phase identification and the study of surface morphology were carried out by X-ray diffraction and scanning electron microscopy. Electrochemical properties were examined by cyclic voltammetry, galvanostatic charge-discharge experiments, and electrochemical impedance spectroscopy. The results show that the film prepared by this method is homogeneous, dense, and crack-free. The thin film has a capacity of 38 μAh/(cm2?μm) with the capacity loss of 0.037% per cycle after being cycled for 100 times. The average diffusion coefficient for lithium ions in the RTA-derived LiMn2O4 thin film is 1 × 10?10 cm2?s?1.WU Xianming HE Zeqiang MA Mingyou XIAO Zhuobing XU Mingfei 2006Rare Metals2006,25,6:2

13Effect of magnesium hydroxide as cigarette paper filler to reduce cigarette smoke toxicity显示文摘The use of magnesium hydroxide(Mg(OH)_(2))was proposed as a filler to replace part of the calcium carbonate(CaCO_(3))in cigarette paper and reduce the toxicity of the smoke from cigarettes.Physical property changes and smoke reducing ability of this possible substitution were effectively studied.The results showed that adding 10%Mg(OH)_(2) could meet the requirements of the physical property of the cigarette paper.Moreover,with the addition of Mg(OH)2 as a filler in the cigarette paper,the pyrolysis temperature of the cigarette paper decreased,while the porosity and specific surface area increased.As a result,the main-stream smoke had a lower smoke total particle matter(STMP),tar,nicotine and carbon monoxide content,and the side-stream smoke also had a lower STMP.Xian Lu Mingyou Liu Zhibin He 2016Journal of Bioresources and Bioproducts2016,1,3:1

17Germ cell sex prior to meiosis in the rainbow trout显示文摘Germ cells make two major decisions when they move from an indeterminate state to their final stage of gamete production.One decision is sexual commitment for sperm or egg production,and the other is to maintain mitotic division or entry into meiosis.It is unclear whether the two decisions are made as a single event or separate events,because there has been no evidence for the presence of germ cell sex prior to meiosis.Here we report direct evidence in the fish rainbow trout that gonia have distinct sexuality.We show that dazl expression occurs in both male and female gonia but exhibits differential intracellular distribution.More strikingly,we show that boule is highly expressed in male gonia but absent in female gonia.Therefore,mitotic gonia possess sex,sperm/egg decision and mitosis/meiosis decision are two independent events,and sperm/egg decision precedes mitosis/meiosis decision in rainbow trout,making this organism a unique vertebrate model for mechanistic understanding of germ cell sex differentiation and relationship between the two decisions.Mingyou Li Qian Shen Foong Mei Wong Hongyan Xu Ni Hong Lingbing Zeng Lin Liu Qiwei Wei Yunhan Hong 2011Protein & Cell2011,2,1:1
