1正己烷在Pt-Ce促进的氧化硅担载的杂多酸金属氧酸盐上的异构化显示文摘制备了用于正己烷临氢异构化的氧化硅担载的Keggin型杂多酸和还原态Pt-Ce氧化物催化剂.这些混合氧化物催化剂或单独使用,或与氧化硅担载的杂多酸催化剂一起使用.用X射线衍射、傅里叶变换红外光谱、傅里叶变换拉曼光谱、热重和N2物理吸附等方法表征在氧化、还原态和催化实验后的催化剂状态.本文的目的是在最佳反应条件(反应温度、还原温度和流量等)下,筛选出具有最好异构化收率的催化剂.结果表明,还原氧化物的存在不但有利于消除积炭,而且在反应期间能有效地维持氧化硅担载杂多酸的结构.从这些催化剂样品中,可以找到具有更好异构化活性和选择性的催化剂.Abdelaziz GHERIB Ahmed AOUISSI Alain RIVES Michel FOURNIER Robert HUBAUT 2007催化学报2007,28,12:4
2Assessment of diaphragmatic function by ultrasonography:Current approach and perspectives显示文摘This article reports the various methods used to assess diaphragmatic function by ultrasonography.The excursions of the two hemidiaphragms can be measured using two-dimensional or M-mode ultrasonography,during respiratory maneuvers such as quiet breathing,voluntary sniffing and deep inspiration.On the zone of apposition to the rib cage for both hemidiaphragms,it is possible to measure the thickness on expiration and during deep breathing to assess the percentage of thickening during inspiration.These two approaches make it possible to assess the quality of the diaphragmatic function and the diagnosis of diaphragmatic paralysis or dysfunction.These methods are particularly useful in circumstances where there is a high risk of phrenic nerve injury or in diseases affecting the contractility or the motion of the diaphragm such as neuro-muscular diseases.Recent methods such as speckle tracking imaging and ultrasound shear wave elastography should provide more detailed information for better assessment of diaphragmatic function.Alain Boussuges Sarah Rives Julie Finance Fabienne Brégeon 2020World Journal of Clinical Cases2020,8,12:3
3Corrosion rate determination of rare-earth Mg alloys in a Na_(2)SO_(4)solution by electrochemical measurements and inductive coupled plasma-optical emission spectroscopy显示文摘The corrosion resistance of three Mg alloys containing rare-earth elements(WE43,EV31 and ZE41)was studied and compared to that of two Mg-Al alloys(AZ31 and AZ91)and of pure Mg(99.95 wt.%).Current-voltage curves and electrochemical impedance measurements were performed with rotating disk electrodes in an aerated 0.1 M Na_(2)SO_(4)solution.For all the alloys,it was confirmed that the intermetallic particles acted as local cathodes and that more protective films were formed on the alloys surface by comparison with the pure Mg.Corrosion rates were determined from inductive coupled plasma-optical emission spectroscopy measurements and from the electrochemical measurements.Higher corrosion rates were observed for the rare-earth Mg alloys compared to the AZ series alloys.These data allowed the corrosion mechanisms to be discussed.Samuel Leleu Bertrand Rives Nicolas Causse Nadine Pébère 2019Journal of Magnesium and Alloys2019,7,1:3
