I received my doctorate in Physics from the university of Wales in Aberystwyth, and from the Royal Institution of Great Britain, the Davy Faraday Research Laboratory in 2004, under the supervision of Professors Neville Greaves and Gopinathan Sankar. I am scientist at the Laboratório Nacional de Luz Sincrotron (LNLS), Centro Nacional de Pesquisa em Energia e Materiais (CNPEM) in charge of the Cateretê beamline where we perform coherent scattering experiments. My research is focussed on material science, catalysis and the study of fast processes (kinetics, zeolites, polymers and nanoparticles). I develop at the Cateretê beamline coherent diffraction imaging techniques to perform in situ time-resolved 3D imaging. (Source: Lattes Curriculum)

Environmental concerns determine the research paths aimed at seeking alternative sources for the production of chemicals that are currently supplied by the petroleum industry. As one of the alternatives, the biomass with the catalytic bioethanol dehydration is a valuable source of diethyl ether (DEE) and ethylene. The latter being important chemicals used either as solvent in organic synt…
The project here described aims to nucleate a new multidisciplinary research group encompassing nanoscience and materials chemistry, with a strong focus on the design, characterization and integration of nanomaterials for applications ranging from photovoltaics and renewable energy to nanomedicine and catalysis. Yet, the development and applicability of nanoscience and nanotechnology rely…

Plant cell walls are plastic structures with a physiological role of protection against pathogens and the environment. The cell wall is a lignin rich matrix and this aromatic polymer represents the main bottleneck to the efficient conversion of polysaccharides into fermentable sugars to produce biofuels and bioproducts. Genetic Engineering holds great promise to generate plants with lower…

Gold (Au) used to be considered to have no catalytic activity because the inert nature of massive gold. However, in 1987 Haruta identified high activity for CO oxidation reaction when gold is supported on metal oxides in a highly dispersed state. Several effects contribute to the catalytic properties of supported nanoparticles catalysts such as particle size, shape and crystalline defects…
Gold nanoparticles are highly active catalysts for CO oxidation, although bulk gold is considered quite inert even to reactive molecules, the nanometer-size gold particles are efficient catalysts. Several effects contribute to the catalytic properties of supported nanoparticles catalysts such as particle size, morphology, interaction with the support, low-coordinated atoms, strain effects…
