Strategies for the Photocatalytic Determination and Removal of Metals and Potentially Toxic Compounds in Environmental Samples
Description
The Project aims to settle strategies for the photocatalytic determination and removal of potentially toxic compounds in environmental samples. Yet, the removal of metals and pollutants, especially metals such as As, Ba, Se, and compounds such as triclosan, caffeine, will be made through photocatalytic processes using the ultraviolet and/or solar radiation in the region, jointly with catalyzers in the form of suspensions and/or immobilized in biopolymers.

Current Development of Technology at the Friction Surfacing and Friction Stir Welding for its Application to the Aeronautic, Navy and Automotive Sectors
Description
The objective of the Project is to focus on the utilization of the best parameters for Friction Surfacing that have been previously studied in: (i) two master dissertation that resulted in the publication of papers in well-known journals and (ii) results of research that take place under the scope of the research agreement about Friction Stir Welding. It focuses, thus, on the continuity of a series of promising results acquired through the utilization of friction surfacing. It enables, then, the acquisition of the best results of resistance to adherence with a microstructural characterization between the surfacing and the aluminum alloy substratum. In this context, the main objective is to perform evaluate the resistance to the fatigue crack (substratum) of two aluminum alloys vested by Friction Surfacing. Therefore, we study the influence of the surfacing in the delay of the fatigue crack. This new stage of the investigation will be used as consumable rods for the aluminum alloy 2024-T3 on the substratum AL 2024-T3 and Al 7050-T7451. Besides, the research project will perform the surfacing of the titanium alloy Ti-6Al-4v on the substrata of Al 2024-T3 and Al 7050-T7451. Such a stage will be developed at the Centre for Materials and Coastal Research (Helmholtz-Zentrum Geesthacht-HZG) in the region of Hamburg, in Germany.

Current Study of the Suitability of Friction Surfacing Processes in the Fabrication of Structural Panels of AL 2024-T3
Description
The objective of this Project is to focus on the performance of the AA2024 alloy surfacing of the substratum AA7050, stemming from the best parameters of friction surfacing processes previously studied at the previous stage with the aluminum alloy 2024-T3. Consequently, once found the best parameters for the surfacing process of AA 2024 on AA7050, we will perform a microstructural characterization of the substratum/surfacing interface, traction trial, bending trial, trial of the fatigue cracking propagation between the AA 2024 surface and the AA7050 aluminum alloy substratum.

Transformation of Plastic Waste in Nanostructured Carbon Materials Applied to the Removal of FE and MN
Description
The objective of this Project is to focus on the performance of surfacing of the AA2024 alloy on the AA7050 substratum, using the best parameters of Friction Surfacing processes previously studied at the previous stage with the 2024-T3 aluminum allow. Consequently, once found the best parameters for the surfacing process of AA 2024 on AA7050, we will perform a microstructural characterization of the substratum/surface interface, traction trial, bending trial, trial of the fatigue cracking propagation between the AA 2024 surface and the AA7050 aluminum alloy substratum.
