Pedro D. Gaspar,Joel Alves,Tânia M. Limaparticular for metal characterization. CO is frequently used as the probe molecule because of the high absorption coefficient of the .(CO) mode and the sensitivity of its frequency to the oxidation state of the site, to its geometry and to its coordinative unsaturation degree. For spectra interpreta

It is then essential to understand how these structures are coupled to one another and how they vary with the metal species, the concentration, the orientation of the surface for semi-infinite materials and/or the cluster siz

Without including the undetermined output of marine life, biosustainable raw materials account for 2000 Gton/year of organic carbon, while only 7 Gton/year of fossil fuels (oil, coal and natural gas) are extracted from the earth.
