Investigation of active species in methanation reaction over cerium based loading

Is the methanation reaction over Ru single crystals structure dependent?

The influence of monoatomic steps and defects on the methanation reaction over ruthenium has been investigated. The experiments are performed on a Ru(0 1 54) ruthenium single crystal, which contains one monoatomic step atom for each 27 terrace atoms. The methanation activity is measured at one bar of hydrogen and CO in a high pressure cell, which enables simultaneous measurements of the local r...

investigation of (meta)discourse markers in elt coursebooks

the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...

Investigation of Nature of The Active Species and Carbene Formation in Photocatalytic Metathesis Reaction

The nature of the active species which lead to the formation of the initiator carbene in photocatalytic metathesis reaction was investigated. The solid phase produced during irradiation was found to involve the active species while the soluble species showed no catalytic activity. The structure of the active solid was analyzed by ESCA, FT IR, NMR and chemical analysis methods and defined as a t...
