| 1 | Syngas Production by Methane Reforming with Carbon Dioxide on Noble Metal Catalysts显示文摘在稳定氧化铝的氧化镁(尖晶石) 上支持的一系列贵金属催化剂(Ru,坚牢酸性蓝 RH,红外,磅,和 Pd ) 被用来由甲烷与二氧化碳改过生产 syngas。综合催化剂用赌注, TPR, TPO, TPH,和 H2S 化学吸着技术被描绘。活动结果为 Ru 干旱坚牢酸性蓝 RH 催化剂显示出高活动和稳定性。TPO 和 TPH 分析显示为 Pd 催化剂的更低的活动和稳定性的主要原因是不太反应的扔的碳的形成和催化剂的 sintering。给词调音:贵金属;syngas;干燥改过;二氧化碳; | M.Rezaei S.M.Alavi S.Sahebdelfar Zi-Feng Yan | 2006 | Journal of Natural Gas Chemistry2006，15，4： | 15 |
| 2 | Linear and nonlinear torsional free vibration of functionally graded micro/nano-tubes based on modified couple stress theory显示文摘The linear and nonlinear torsional free vibration analyses of functionally graded micro/nano-tubes(FGMTs) are analytically investigated based on the couple stress theory.The employed non-classical continuum theory contains one material length scale parameter,which can capture the small scale effect.The FGMT model accounts for the through-radius power-law variation of a two-constituent material.Hamilton's principle is used to develop the non-classical nonlinear governing equation.To study the effect of the boundary conditions,two types of end conditions,i.e.,fixed-fixed and fixed-free,are considered.The derived boundary value governing equation is of the fourthorder,and is solved by the homotopy analysis method(HAM).This method is based on the Taylor series with an embedded parameter,and is capable of providing very good approximations by means of only a few terms,if the initial guess and the auxiliary linear operator are properly selected.The analytical expressions are developed for the linear and nonlinear natural frequencies,which can be conveniently used to investigate the effects of the dimensionless length scale parameter,the material gradient index,and the vibration amplitude on the natural frequencies of FGMTs. | A.R.SETOODEH M.REZAEI M.R.ZENDEHDEL SHAHRI | 2016 | Applied Mathematics and Mechanics(English Edition)2016，37，6： | 2 |
| 3 | Preparation and thermal treatment of Pd/Ag composite membrane on a porousα-alumina tube by sequential electroless plating technique for H_2 separation显示文摘Pd/Ag/α-Al 2 O 3 合成的膜被顺序的无电的 plating 准备技术。准备的膜被 X 光检查衍射(XRD ) 描绘,扫描电子显微镜学(SEM ) ,精力散光谱学,和诱导地联合的血浆原子排放光谱学技术(ICP-AES ) 。退火的效果氢浸透流动和合金的形态学上的时间, Ag 内容,和空气处理被调查。调查的结果证明试管的准备类型为膜准备作为底层有一个好潜力。另外,一致没有缺点的合金被在 H 2 空气在 550 ° C 退火准备。浸透结果由增加 Ag 内容和退火的时间在 H 2 浸透流动显示出增加。另外,在为 1 h 的 400 ° C 的准备的膜的空气处理改变了合金的形态学并且实质地提高了氢流动。 | E.Navaei Alvar M.Reza Golmohammadi M.Rezaei H.Navaei Alvar A.Mardanloo S.Habibzad Nouhian M.Didari | 2008 | Journal of Natural Gas Chemistry2008，17，4： | 1 |
