Ciência & Tecnologia dos Materiais is the official journal of SPM, the Portuguese Society of Materials (Sociedade Portuguesa de Materiais), providing a forum for publishing peer-reviewed papers related to both fundamentals of materials science and technological application of engineering materials. The scope of the journal covers a wide range of topics in materials science that are of interest to the SPM, encompassing electrochemistry, corrosion and protection of materials, extractive metallurgy and recycling, electronic and optoelectronic materials, biomaterials, forest materials, polymeric and composite materials, foundry, heat treatment and surface engineering, tribology, and fracture. Science and Technology of Materials welcomes contributions in the form of original research papers, review articles and technical notes reporting advances on those fields, emphasizing new materials, new products and devices, and new technologies.

A method for simultaneous removal of CO2, SOX and NOX from industrial flue gases through the injection of ozone diluted in nitrogen, oxygen or nitrogen/oxygen mixtures, as an oxidizing agent and with the addition of specific sequestrants, that induce the precipitation of nitrates and sulphates, is presented. This new process is related with the conventional CO2 removal method using chemical absorption, but presents as main innovation the possibility to remove also simultaneously SOX and NOX.
