Influence of active material content on the performance of direct ink printed l...
Pinto, Rafael S.; Hilliou, L.; Petrenko, Viktor; Costa, Carlos Miguel Silva; Lanceros-Mendez, S.; Gonçalves, Renato FerreiraDriven by the growing demand for small devices due to the Internet-of-Things concept, lithium-ion batteries (LIBs) represent an essential technology to store energy for portable electronics with specific sizes/requirements. The LIBs' performance is highly dependent on the electrodes' composition/microstructure, particularly the cathode. In this work, it is investigated the influence of different ratios between ...
Tailoring poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) memb...
Pinto, Rafael S.; Serra, João Pedro Cruz; Barbosa, João Carlos Pacheco; Silva, Maria Manuela; Salado, Manuel; Fidalgo Marijuan, Arkaitz; Amayuelas, EderNovel battery separators based on poly(vinylidene fluoride-co-trifluoroethylene-chlorofluoroethylene)- P(VDF-TrFE-CFE)- were produced by different processing techniques (non-solvent and thermally induced phase separation, salt leaching and electrospinning), in order to evaluate their effect on separator morphology, degree of porosity and pore size, electrochemical parameters and battery cycling behavior. It has...
Tuning the properties of gelatin films through crosslinking and addition of ion...
Etxabide, Alaitz; Carvalho, Estela; Pereira, Nelson; Correia, Daniela; Guerrero, Pedro; Costa, Carlos M.; Caba, Koro de la; Lanceros-Mendez, S.The exploration into biopolymer applications has experienced fast growth in recent years due to the ever-growing environmental and societal demand for a greener and safer environment. In this study, fish gelatin-based films with fructose and different choline-based ionic liquids, such as choline dihydrogen phosphate, choline acetate, and choline serinate, were prepared to assess the effect of Maillard reaction ...
Tailoring the electrical response of polyvinylidene fluoride nanocomposites wit...
Marinho, Tiago André Rodrigues; Tubio, Carmen Rial; Lanceros-Mendez, S.; Costa, Pedro Filipe RibeiroPolymer-based composites combining the flexibility, low density, and processability of the matrix with the tailored functional performance provided by the fillers are also particularly suitable for large area, flexible, and printable applications. Herein, polyvinylidene fluoride (PVDF) composites with conductive graphene nanoplatelets (G-NPL) and high-dielectric constant ceramics, including barium and strontium...
Wool/soy protein isolate membranes as separators toward more sustainable lithiu...
Serra, J. P.; Barbosa, J. C.; Silva, Maria Manuela; Gonçalves, Renato Ferreira; Uranga, J.; Costa, Carlos Miguel Silva; Guerrero, P.; de la Caba, K.Natural origin products exist in large quantities around the world and many times they are not properly exploited in order to realize their potential in novel applications, being often even discarded as by-products from other uses. In this study, wool and soy protein isolate (SPI) are proposed to develop separator membranes for lithium-ion batteries (LIBs), aiming toward a new generation of sustainable batterie...
State of the art and current challenges on electroactive biomaterials and strat...
Marques-Almeida, Teresa; Lanceros-Mendez, S.; Ribeiro, Clarisse Marta OliveiraThe loss or failure of an organ/tissue stands as one of the healthcare system's most prevalent, devastating, and costly challenges. Strategies for neural tissue repair and regeneration have received significant attention due to their particularly strong impact on patients' well-being. Many research efforts are dedicated not only to control the disease symptoms but also to find solutions to repair the damaged ti...
Engineering the magnetic properties of acrylonitrile butadiene styrene-based co...
Merazzo, Karla J.; García Díez, Ander; Tubio, Carmen R.; Manchado, Juan Carlos; Malet Murillo, Ramón; Pérez, Marc; Costa, Pedro Filipe RibeiroThis work reports the engineering of the magnetic properties of composites based on acrylonitrile butadiene styrene (ABS) by the inclusion of different magnetic nanoparticles (MNP). ABS-based composites with different MNP, including permalloy, Fe3O4, CoFe2O4, Ni, and Co-carbon coated, with a 10 wt% content have been prepared and their morphological, electric, thermal, magnetic, and mechanical properties evaluat...
Tailoring the electrical conductivity of Poly(vinylidene fluoride) by blending ...
Martins, Luis Amaro; Teruel Biosca, Laura; Sabater i Serra, Roser; Balado, Andreu Andrio; Gómez-Tejedor, José Antonio; Correia, Daniela M.In order to tailor dielectric response and electrical conductivity, novel polymer blends based on poly(vinylidene fluoride (PVDF) and different fillers composed by poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), and PEDOT:PSS/ionic liquids (ILs): PEDOT:PSS/N-ethyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide ([C2mpyr][FSI]) and PEDOT:PSS/N-ethyl-N-methylpyrrolidinium bis(trifluoromethane...
An interactive hybrid book integrating capacitive, piezoelectric, and piezoresi...
Gonçalves, Sérgio Abílio Pereira; Pereira, Nelson Miguel Macedo Silva; Costa, Carlos Miguel Silva; Branco, Pedro; Lanceros-Mendez, S.The arising of novel paradigms in human–computer interaction, including tangible user interfaces, shape-changing interfaces, or ubiquitous computing, is breaking down the boundary between physical and digital realms, leading to more natural and immersive forms of interaction. Advances in active and responsive smart materials allow to transform once inanimate objects, such as books, into actively responsive obje...
Unveiling challenges and opportunities in silicon-based all-solid-state batteri...
Zhao, Mingcai; Zhang, Juan; Costa, Carlos Miguel Silva; Lanceros-Mendez, S.; Zhang, Qi; Wang, WeiLi-metal and silicon are potential anode materials in all-solid-state Li-ion batteries (ASSBs) due to high specific capacity. However, both materials form gaps at the interface with solid electrolytes (SEs) during charging/discharging, resulting in increased impedance and uneven current density distribution. In this perspective, the different mechanisms of formation of these gaps are elaborated in detail. For L...
