Nov 14, 2024 \u2013 Dec 31, 2025, CAPES: Call No. 07\/2024 \u2013 Magnetic Systems for Bioremediation. Move la America<\/strong><\/p>\n

The general objective of the work plan is to design and characterize magnetic microcapsules as vehicles for cyanobacteria. It aims to assess the viability of cyanobacteria and the potential use of materials for removing specific contaminants from water. To achieve this, the following specific objectives will be pursued:<\/p>\n

Jul 1, 2023 \u2013 Jun 30, 2025, FAPESP \u2013 Regular Grant: Ferrofluids for Viscous Fluid Flow Applications.
\n<\/strong><\/p>\n

This project seeks to enhance the magnetic properties of ferrofluids to optimize the conversion of electromagnetic energy into heat via the magneto-hyperthermia (MH) effect, for application in the recovery and transport of oil or any viscous fluid by reducing its viscosity. MH is a phenomenon in which the temperature of a system containing magnetic nanoparticles (NPs) increases when exposed to an alternating magnetic field, as the electromagnetic energy is converted into heat through the magnetization reversal of the NPs. Viscosity, on the other hand, decreases as temperature rises. Highly viscous liquids are present in several industries, including Oil & Gas, pharmaceuticals, chemical, and food sectors, where reducing viscosity can lead to lower extraction or transportation costs. The potential implementation of magnetic nanoparticles in this technological challenge originates from a fundamental issue related to the dispersion of NPs in viscous fluids. Therefore, this project aims to develop new synthesis methods for colloidal magnetic nanoparticle systems, targeting their implementation in fluid extraction or transport technologies.<\/p>\n

Mar 1, 2024 \u2013 Feb 28, 2027, CNPq \u2013 Magneto-hyperthermia in Clustered Nanoparticles.
Productivity in Research Grant, PQ2.<\/strong><\/p>\n

This project is of significant scientific and technological relevance. From a technological perspective, it could lead to the development of new technologies that reduce costs in processes involving the transport of viscous liquids, with potential applications across a broad range of industries. Additionally, magnetic nanoparticles can be easily recovered and reused. From a scientific standpoint, the project will contribute to the generation of knowledge in the field of colloidal NP dispersions\u2014a cross-cutting topic relevant to any colloidal NP system, magnetic or non-magnetic.<\/p>\n

There is no consensus in the international scientific community regarding the effects of dipolar interactions between magnetic nanoparticles and their consequences on heat capacity. This project will also contribute to the training of new researchers, with a minimum of three undergraduate students and one master\u2019s student involved, in addition to a postdoctoral researcher contributing to various activities.<\/p>\n
