Alexandra Pinto

Associate Professor

      

Profile
In an early stage of her career, after PhD in 1991 on Combustion, oriented her activities to the Transport Phenomena area with particular interest in Mass Transfer and Characterization of two-phase flow patterns using advanced optical techniques.

More recently, integrated the know how acquired with other skills of the core formation in Chemical Engineering, in Energy applications in particular in the Fuel Cell area, namely the Direct Methanol and Ethanol Fuel Cells (modelling and experimental studies, macro and micro scale), Microbial Fuel Cells, PEM Fuel Cells and Electrolysers and Hydrogen Generators and Storage (Chemical Hydrides) systems.

The main target is the development of solutions to efficiently produce energy for different applications which is strategically aligned to Horizon 2020 goals. Impact is expected in the transports sector (by increasing the Hydrogen storing capacity and PEM fuel cells optimization), in the wind sector (by developing more efficient PEM fuel cells and electrolysers for an alternative back-up power system) and in the portable sector (by designing micro direct alcohol fuel cells). By converting a variety of materials such as complex organic wastes or renewable biomass into electricity, Microbial fuel cells can be advantageously combined with applications in wastewater treatment.

Director of the Doctoral Program in Chemical and Biological Engineering (PDEQB), Chemical Engineering Department, FEUP, Portugal, since 2010. The program has an average number of 90 PhD students and produces around 14 PhD theses per year.

Was a member of European Network FCTESTNET (Fuel Cell Testing and standardisation Network).Is regularly invited to be an expert evaluator of Horizon 2020 Projects – Storage – Low Carbon Energy, FCH – Fuel Cells and Hydrogen, ITN – Marie Sklodowska-Curie

          Profile
          I obtained my bachelor’s degree in Physics (“Applied Physics and Electronics”) from the Faculdade de Ciências da Universidade do Porto. I got my PhD in Physics (area of Plasma Physics) from the Instituto Superior Técnico, Lisboa.

          I am an associate Professor at the Department of Physics Engineering of Faculdade de Engenharia da Universidade do Porto (FEUP), where I began to teach when I finished my bachelor degree. I usually teach general physics (mainly Newtonian mechanics, thermodynamics, optics, electromagnetism) and more recently Plasma Physics for various Programmes/Cycle of Studies, as the Integrated Masters in Bioengineering, Civil Engineering, Electrical and Computers Engineering, Physical Engineering and Chemical Engineering.

          Between 2010 and 2012, I was the Director of the Doctoral Program in Engineering Physics (PRODEF) at FEUP.Since 2010, I am the Director of the Department of Physics Engineering of FEUP.

          My scientific areas of research are the study of the kinetics of electrons, heavy neutrals and positive and/or negative ions in electrical discharges in gases (atomic, molecular and mixtures of both, in particular argon, nitrogen and oxygen) at DC, HF, and microwave discharges. More recently, I am interested in the simulation of plasma thrusters for electric propulsion technologies, in particular electrohydrodynamic (EHD) thrusters.
