Carapeto, M. J.; Grácio, L.; Pires, H.; Farinha, A.; Miranda, D.The project “Stronger Youth”- Empowering young people social competences and soft skills through peer mentoring” highlight the urgency of addressing the issue of mental health among adolescents. It aims to prevent depressive behaviors and social exclusion among young people by providing a methodology and complete toolkit for conducting peer mentoring. This document concerns the research task of Work Package #2 ...
Theoretical simulation of solid polymer electrolytes based on poly(vinylidene f...
Miranda, D.; Barbosa, J.C.; Gonçalves, R.; Miranda, Francisco; Vilaça, J.; Costa, C.M.; Lanceros-Méndez, S.Solid polymer electrolyte composited by poly(vinylidene fluoride) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) has been optimized for solid-state lithium-ion batteries taking into account the LiTFSI concentration. Computer simulations of battery systems was used to evaluate the influence of LiTFSI concentration at different battery operation temperatures (278.15 K, and 353.15 K) and different dischar...
Printable piezoresistive polymer composites for self-sensing medical catheter d...
Pimentel, E.; Costa, Pedro Filipe Ribeiro; Tubio, C. R.; Vilaça, J. L.; Costa, Carlos Miguel Silva; Lanceros-Mendez, S.; Miranda, D.There is a constant demand for new and/or improved health treatments that require flexible sensor devices. This is particularly relevant in relation to neurogenic bladder dysfunction. In this context, polymer composites have been developed based on three different matrices, carboxymethyl cellulose (CMC), styrene-ethylene/butylene-styrene (SEBS) and polyvinyl alcohol (PVA), with different concentrations of multi...
Structural mechanical simulation to optimize the sensor arm geometry to be impl...
Veloso, F.; Miranda, D.; Morais, Pedro; Torres, Helena R.; Laranjeira, Roberto; Ruediger, Mario; Miranda, Francisco; Pinho, António C. M.; Vilaça, J. L.For the treatment of moderate and severe cases of deformational plagiocephaly, an asymmetrical deformation of the skull, a cranial remodeling orthosis (CRO) is used. For the development of a new CRO concept, a pressure sensor grid is placed inside the orthosis that will allow the monitoring of excessive pressures and incorrect CRO positioning throughout the treatment. To implement the sensor grid in the CRO, hi...
Lattice microstructure design for cathode electrodes for high-performance lithi...
Miranda, D.; Gonçalves, R.; Veloso, F.; Miranda, Francisco; Vilaça, J.; Costa, C. M.; Lanceros-Méndez, S.The electrode geometry is an essential parameter affecting the cycling performance of batteries. In this work, the effect of lattice geometry of the cathode electrode on battery performance was studied by theoretical simulations keeping its volume constant. It was observed that the variation of the lattice geometry improves the cycling performance when compared to conventional planar geometry. The improvement o...

Gonçalves, Renato Ferreira; Miranda, D.; Marques-Almeida, T.; Silva, M.M.; Cardoso, Vanessa Fernandes; Almeida, A.M.; Costa, C.M.; Lanceros-Méndez, S.In order to improve battery performance by tuning battery separator membranes, this work reports on porous poly(vinylidene fluoride-co-trifluoroethylene) - P(VDF-TrFE)- membranes with surface pillar microstructures. Separators with tailored pillar diameter, height and bulk thickness were fabricated by template patterning and computer simulations, allowing to evaluate the effect of the pillar microstructure char...

Mendes-Felipe, Cristian; Barbosa, J. C.; Gonçalves, Renato Ferreira; Miranda, D.; Costa, Carlos Miguel Silva; Vilas-Vilela, J. L.; Lanceros-Méndez, S.The increased demand of electronic devices promotes the development of advanced and more efficient energy storage devices, such as batteries. Lithium-ion batteries (LIBs) are the most studied battery systems due to their high performance. Among the different battery components, the separator allows the control of lithium ion diffusion between the electrodes. To overcome some drawbacks of liquid electrolytes, in...
