Correlating mechanical strain with low-temperature hydrogenation activity on submonolayer Ni/W (110) surfaces

Article Abstract:

Cyclohexene (c-C (sub 6) H (sub 10) is used as a probe molecule to investigate the hydrogenation activity of Ni films deposited on a W (110) surface. Using Auger electron spectroscopy (AES), temperation programmed desorption (TPD), low-energy electron diffraction (LEED), X-ray photoelectron spectroscopy (XPS), and high-resolution electron energy loss spectroscopy (HREELS), the reaction products and the bonding mechanism of cyclohexene on various Ni/W (110) surfaces are studied.

Solvation of p-nitrophenol at a water/alkane interface: The role of ionic strength and salt identity

Article Abstract:

The interfacial solvation of a neutral surfactant, p-nitrophenol (PNP), adsorbed to the water/cyclohexane interface in the presence of simple salts at varying salt concentrations is studied. A spectral red shift of the PNP electronic excitation implies an increase in local polarity.

Observation of novel low-temperature hydrogenation activity on Co/Pt(111) surfaces

Article Abstract:

The reactions of hydrogen, ethylene and cyclohexene are investigated on Co/Pt(111) surfaces using temperature-programmed desorption (TPD). It was found that when Co is deposited on Pt(111) at 0.5-1 ML (monolayer) Co coverage.
