This book was released on 1990 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: At one-third coverage of carbon monoxide, a (3 x 3)R30 deg low energy electron diffraction (LEED) pattern has been observed on Ni(111), Pd(111) and Pt(111). Interestingly, the C-O stretching frequency indicates three completely different adsorption sites; a 2-fold bridge site for Ni(111), a 3-fold site for Pd(111), and an on-top site for Pt(111). As the coverage increases to one-half, a c(4x2) Leed pattern appears. For Ni(111) and pd (111), the adsorbate seems to prefer the 2-fold site. On Pt(111), half of the chemisorbed CO sits on the on- top site while the other half is located at the 2-fold site. Further increase in coverage results in titled CO molecules on Pt(111) and adsorption of CO at the on-top site of Ni(111) and Pd(111). To rationalize these observations, we carried out extended Huckel calculations within the tight-binding formalism. Our discussion is augmented by conceptual tools such as density of states and crystal orbital overlap population. We also examine the question of the adequacy of the Blyholder model in describing the adsorbate-surface interaction. (js).

This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: TUNNELING SPECTROSCOPY IS USED TO STUDY THE CHEMISORPTION OF CO on small nickel particles. The particles are grown from vapor on a thermally oxidized aluminum substrate. Carbon monoxide is observed to chemisorb in at least four distinct ways, giving CO stretching frequencies of 256.5, 246, 222 and 207 meV. The 256.5 meV species has low frequency modes at 45.5 and 59.5 meV. The low frequency modes of the remaining three species are not resolved sufficiently for identification. The frequencies of all modes were found to have some coverage dependence. The largest shift is seen in a CO stretching vibration that moves from 200 to 207 meV with increasing coverage. The effect of H2 co-adsorption is examined and evidence for the presence of oxygen on the particles is presented. The reaction of the chemisorbed CO with H2 on these nickel particles is found to produce very little surface hydrocarbon in contrast to results found previously for rhodium particles under similar conditions.

Download or read book Surface Analysis Methods in Materials Science written by D.J. O'Connor and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book stemmed from a remark by Philip Jennings of Murdoch University in a discussion session following a regular meeting of the Australian Surface Science group. He observed that a text on surface analysis and applica tions to materials suitable for final year undergraduate and postgraduate science students was not currently available. Furthermore, the members of the Australian Surface Science group had the research experience and range of coverage of sur face analytical techniques and applications to provide a text for this purpose. A of techniques and applications to be included was agreed at that meeting. The list intended readership of the book has been broadened since the early discussions, particularly to encompass industrial users, but there has been no significant alter ation in content. The editors, in consultation with the contributors, have agreed that the book should be prepared for four major groups of readers: - senior undergraduate students in chemistry, physics, metallurgy, materials science and materials engineering; - postgraduate students undertaking research that involves the use of analytical techniques; - groups of scientists and engineers attending training courses and workshops on the application of surface analytical techniques in materials science; - industrial scientists and engineers in research and development seeking a description of available surface analytical techniques and guidance on the most appropriate techniques for particular applications. The contributors mostly come from Australia, with the notable exception of Ray Browning from Stanford University.
Download or read book Hydrogen Materials Science and Chemistry of Metal Hydrides written by Michael D. Hampton and published by Springer Science & Business Media. This book was released on 2002-08-31 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of metal hydrides opens up promising avenues for the solution of world energy problems, as well as casting light on the interactions of hydrogen with materials, the role of hydrogen in materials science, and the chemistry of metal hydrides, all of which are discussed in this book in terms that range from a global look at the new vision of energy and how hydrogen fits into that future to reviews such as a look at nickel hydride over the last 40 years. Very specific current research in such areas as hydrogen in materials science discuss properties like superconductivity, diffusion EMF, magnetic properties, physicochemical properties, phase composition, and permeability. Hydrogen can also be used as a processing or alloying agent, and in the synthesis of battery electrodes, composite materials and alloys. The interaction of hydrogen with many metals, composites and alloys offers potential hydrogen storage systems. There is also a discussion of hydrogen sensors.
