Sequential desorption of dimers from square lattices: A novel mechanism for phase transitions
(Elsevier Science, 2010-10)
This work describes a novel mechanism for phase transitions during desorption, involving the formation of lattice size dependent intermediate states when there is enough adsorbate mobility. Monte Carlo simulations are ...
Kinetics of low-temperature CO oxidation on Au(111)
(Elsevier Science, 2015-12-22)
The oxidation of carbon monoxide on oxygen-modified Au(111) surfaces is studied using a combination of reflection-absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD). TPD reveals that CO ...
The desorption and reaction of 1-alkenes and 1-alkynes on Cu(111) and copper foils
The adsorption of a series of 1-alkene and 1-alkynes is examined both on Cu(111) single crystals and a polycrystalline copper foil in order to explore the influence of low-coordination sites expected to be present on the ...
Growth, Structure, Phase Transitions and Desorption Kinetics of N-Dotriacontane Films
In this work we present studies of thin n-dotriacontane (C32) films deposited by physical vapor deposition (PVD) onto Si(JOO) substrates with their native silicon oxide layer. To have a good comprehension of this system ...
Polyethylenimine-Magadiite Layered Silicate Sorbent for CO2 Capture
(Amer Chemical SocWashingtonEUA, 2014)
Toward Understanding Metal-catalyzed Ethanol Reforming
(AMER CHEMICAL SOCWASHINGTON, 2015)
Improved activity and stability of Ce-promoted Ni/γ-A1 2O3 catalysts for carbon dioxide reforming of methane
The CO2 reforming of CH4 was carried out over Ni catalysts supported on γ-Al2O3 and CeO 2-promoted γ-Al2O3. The catalysts were characterized by means of surface area measurements, TPR, CO2 and H2 chemisorption, XRD, SEM, ...
Metal-phthalocyanine ordered layers on Au(110): Metal-dependent adsorption energy
(American Institute Of Physics, 2014-06)
Iron-phthalocyanine and cobalt-phthalocyanine chains, assembled along the Au(110)-(1×2) reconstructed channels, present a strong interaction with the Au metallic states, via the central metal ion. X-ray photoemission ...
