1犹他州Bluebell-Altamont油田裂隙气藏P波和S波方位各向异性响应显示文摘本文利用P波和S波反射数据描述第三系Upper Green River组天然裂隙气藏的方位各向异性并阐述两种数据体的优点和能力。目的是评估P波地震资料检测气充填裂隙的可行性,估算裂隙密度和方位,并与S波的结果作比较。垂直裂隙的P波响应必须根据不同炮-检方位(传播路径)与裂隙走向的角度进行分析。两条多分量反射资料的测线埋置为近似平行和垂直Upper Green River组裂隙的主方向,该方向由露头岩芯分析和测井数据成像确定。根据数据的叠前振幅随偏移距变化(AVO)分析P波振幅响应并与Upper Green River气砂岩/盐水砂岩各向同性模式的AVO作比较。另外还采集了九分量的垂直地震剖面(VSP)的资料,利用P波反射标定S波反射并佐证反射S波勘探成果。 反射资料的快横波S1分量的方向和VSP资料的S1分量的方向一致,在Upper Green River组裂隙方向为NW(北西向),这与最大水平应力方向和测井的椭圆率方向相同。平行和垂直Upper Green River组裂隙观察的P波AVO梯度之间有明显的差别。当传播路径垂直裂隙时,P波AVO梯度值为正,并与产气层裂隙有关。在含水层区,AVO梯度接近于零和负值。在裂隙层顶部观测的P波AVO梯度的方位变化与裂隙层内S波分裂(S波各向异性)的垂直旅行时之间的时差存在一定的比例关系。Heloise B.Lynn 黄中玉 2000石油物探译丛2000,,2:4

9Inverse single-site Fe_(1)(OH)_(x)/Pt(111)model catalyst for preferential oxidation of CO in H_(2)显示文摘Inverse oxide/metal model systems are frequently used to investigate catalytic structure-function relationships at an atomic level.By means of a novel atomic layer deposition process,growth of single-site Fe_(1)O_(x) on a Pt(111)single crystal surface was achieved,as confirmed by scanning tunneling microscopy(STM).The redox properties of the catalyst were characterized by synchrotron radiation based ambient pressure X-ray photoelectron spectroscopy(AP-XPS).After calcination treatment at 373 K in 1 mbar O_(2).the chemical state of the catalyst was determined as Fe^(3+).Reduction in 1 mbar H_(2) at 373 K demonstrates a facile reduction to Fe2+and complete hydroxylation at significantly lower temperatures than what has been reported for iron oxide nanoparticles.At reaction conditions relevant for preferential oxidation of CO in H_(2)(PROX),the catalyst exhibits a Fe3+state(ferric hydroxide)at 298 K while re-oxidation of iron oxide clusters does not occur under the same condition.CO oxidation proceeds on the single-site Fei(OH)3 through a mechanism including the loss of hydroxyl groups in the temperature range of 373 to 473 K,but no reaction is observed on iron oxide clusters.The results highlight the high flexibility of the single iron atom catalyst in switching oxidation states,not observed for iron oxide nanoparticles under similar reaction conditions,which may indicate a higher intrinsic activity of such single interfacial sites than the conventional metal-oxide interfaces.In summary,our findings of the redox properties on inverse single-site iron oxide model catalyst may provide new insights into applied Fe-Pt catalysis.Chunlei Wang Heloise Tissot Markus Soldemo Junling Lu Jonas Weissenrieder 2022Nano Research2022,15,1:1

20新冠大流行:人类何去何从?显示文摘3月11日,世界卫生组织总干事宣布新冠肺炎疫情已具有“大流行”的特征。这个词一度只会让人联想起灾难电影的桥段或是历史上爆发过的恐怖瘡疫。然而近几个月来,新冠肺炎却着实让全世界陷入了大流行的困境。我们为何会走到这般境地?怎样才能从疫情中走出来?疫情结束后,人类将会怎样?一场前所未有的全球公共卫生战役已经打响。Vincent Nouyrigat Yves Sciama Heloise Rambert Hugo Leroux 王隽(编译) 2020新发现2020,,6:0
