Vibrational study of the interaction of acetylene and benzene on clean and carbide-modified W(211) surfaces

Article Abstract:

A study was conducted to analyze the chemistry of acetylene on clean and carbide-altered W(211) surfaces using high-resolution electron energy-loss spectroscopy and temperature-programmed desorption measurements. An ultrahigh vacuum chamber supporting an LK-3000 high-resolution electron energy-loss spectrometer was utilized to examine the structure of acetylene. Experimental results indicated that CH bond activation was suppressed on the carbide-modified tungsten surface.

Transport coefficients of an inorganic Brownian particle in solution: the tungstosilicate anion

Article Abstract:

The theoretical and experimental investigation of the transport properties of the tungstosilicate ion in aqueous solutions is exposed. The result indicates that the sodium tungstosilicate electrolyte exhibits a behavior similar to a simple electrolyte in aqueous solution, whereas the addition of a salt yields an ionic association phenomenon.

Modifying surface reactivity by carbide formation: reaction pathways of cyclohexene over clean and carbide-modified W(111)

Article Abstract:

The decomposition and dehydrogenation of cyclohexene (c-C6H10) are used s probe reaction to compare the surface reactivities of clean and carbide-modified W(111). It is concluded that the desorption of the benzene product is reaction-limited on C/W(111), but it is desorption-limited on Pt(111).
