The effect of conditioned medium from human amniotic membrane-derived mesenchym...
Silva, C. S.; Casanova, Marta Alexandra Rodrigues; Ferreirinha, P.; da Silva Morais, A.; Osório, H.; Lima, A. C.; Fangueiro, J. F.; Cerqueira, M. T.Aims: The development and selection of T cells occur within the thymus. This organ involutes throughout life, compromising the generation of T cells and, consequently, the efficacy of the immune system. Mesenchymal stem cells (MSC) have beneficial effects on the immune system. Therefore, MSC have been applied in different pathologies related with thymic function. However, there is a lack of knowledge on the pot...
Advances in printing and electronics: from engagement to commitment
Martins, Pedro Libânio Abreu; Pereira, N.; Lima, A. C.; Garcia, A.; Mendes-Filipe, C.; Polícia, R.; Correia, V.; Lanceros-Mendez, S.In recent years, printed electronics reached enormous popularity as a result of their huge potential to offer unique features that are not attainable through traditional fabrication, namely low-cost production, multifunctionality, stretchability, sustainability, and flexibility. Being expected a galloping increase in the use of printed technologies in the near future, due to the digitalization efforts associate...
Improving the performance of paper-based dipole antennas by electromagnetic flu...
Carvalho, R.; Brito-Pereira, R.; Pereira, N.; Lima, A. C.; Ribeiro, Clarisse Marta Oliveira; Correia, V.; Lanceros-Mendez, S.One of the essential issues in modern advanced materials science is to design and manufacture flexible devices, in particular in the framework of the Internet of Things (IoT), to improve integration into applications. An antenna is an essential component of wireless communication modules and, in addition to flexibility, compact dimensions, printability, low cost, and environ-mentally friendlier production strat...
Greener solvent-based processing of magnetoelectric nanocomposites
Lima, A. C.; Pereira, N.; Ribeiro, Clarisse Marta Oliveira; Lanceros-Méndez, S.; Martins, Pedro Libânio AbreuPolymer-based magnetoelectric (ME) nanocomposites are an enabling material technology for a wide range of applications in the area of digitalization strategies. Due to its highest piezoelectric response among polymers, poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) is the piezoelectric matrix most used in polymer-based ME materials with over 80% of the total reports, with the resulting composites typic...

Rodrigues-Marinho, T.; Lima, A. C.; Martins, P.; Costa, P.; Lanceros-Méndez, S.Piezoelectric materials are increasingly being used in a wide range of applications. Single crystals, ceramics and polymers are all being used sensors, actuators and energyharvesting applications. Among the most used piezoelectric materials are lead zirconate titanate (PZT) and barium titanate (BaTiO3) ceramics and the polymer poly(vinylidene fluoride) (PVDF). Polymer-based composites including high dielectric ...
Isolation and characterization of 25 microsatellite DNA loci for Anopheles albi...
Guimarães-Marques, Giselle Moura; Batista, Jacqueline da Silva; Guimarães, H. M.; Naice-Daou, M. V.; Lima, M. P.; Formiga, Kyara M.The Anopheles albitasis complex includes 6 species, and 3 are considered as malaria vectors in Brazil. Twenty-five polymorphic microsatellite DNA loci were isolated and characterized in 24-36 individuals from the neighborhood of Puraquequara, Manaus, Amazonas State, Brazil. The number of estimated alleles ranged from 2 to 10, the observed heterozygosity ranged from 0.182 to 0.897, and the expected heterozygosit...
