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...
Enhanced performance of solid polymer electrolytes combining poly(vinylidene fl...
Macedo, V. M.; Barbosa, J. C.; Salazar, H.; Fidalgo-Marijuan, A.; Gajjala, R. K. R.; Almásy, L.; Gonçalves, B. F.; Petrenko, V. I.; Silva, M. M.The search for sustainable and high-performance materials for lithium-ion batteries is leading to significant advances in solid polymer electrolyte (SPE) technology. However, the current drawbacks of this approach prove the need for further research and development in the field. Herein, novel ternary solid polymer electrolytes have been developed using varying loads of MOF-808 metal-organic framework and [BMIM]...
Analyzing the potential of selected gut commensal strains to produce antimicrob...
Fonseca, M.; Machado, D.; Vedor, R.; Andrade, J. C.; Gomes, A. M.; Barbosa, J. C.The World Health Organization estimates that the number of antibiotic resistance-related deaths could reach 10 million by 2050 [1]. Given the dynamics and high diversity of microorganisms that inhabit the gastrointestinal tract, this is the ideal place to discover new antimicrobial peptides (AMP) to replace traditional antibiotics [2]. Among the most extensively studied members are the commensal strains Akkerma...
Ionic liquids in the scope of lithium-ion batteries: from current separator mem...
Barbosa, J. C.; Correia, Daniela Maria Silva; Gonçalves, Renato Ferreira; de Zea Bermudez, V.; Lanceros-Méndez, S.; Costa, Carlos Miguel SilvaA relevant issue associated with the environmental impact of current and future technologies is the balance between performance and sustainability. In this regard, there is an effort to increase the sustainability of energy storage systems and, in particular, of lithium-ion batteries, by replacing the most harmful battery components with environmentally friendlier ones. The application of ionic liquids, both as...
Molecular design of functional polymers for organic radical batteries
Barbosa, J. C.; Fidalgo-Marijuan, A.; Dias, J. C.; Gonçalves, Renato Ferreira; Salado, M.; Costa, Carlos Miguel Silva; Lanceros-Méndez, S.The growing demand for energy storage devices calls for the development of more efficient and sustainable systems. As the current lithium-ion batteries present several safety issues, as well as environmental hazards, some alternatives need to be taken into consideration. The area of organic materials based batteries is gaining interest as they allow for the replacing of the currently used metals, with significa...
Characterization of 70.5% cocoa content dark chocolate incorporated with Bifido...
Vedor, R.; Machado, D.; Barbosa, J. C.; Gomes, A. M.Currently, probiotics are defined as "live microorganisms that, when administered in adequate amounts, confer a health benefit on the host” [1].Bifidobacterium animalis subsp. lactis BB-12® is one of the most common probiotics used as a food supplement [2]. Chocolate is one of the most popular and appealing culinary products, with various cocoa percentages available to consumers [3;4]. Several studies have sugg...
Hydrophobicity and aggregation properties of gut commensals faecalibacterium du...
Fonseca, M.; Machado, D.; Vedor, R.; Barbosa, J. C.; Andrade, J. C.; Gomes, A. M.Probiotics have been emerging as a promising approach to prevent and control foodborne diseases [1]. In the last years, the bacterial species isolated from gut microbiota, such as Faecalibacterium spp. and Akkermansia muciniphila, have been proposed as novel probiotic candidates [2]. The cell surface hydrophobicity, auto-aggregation and co-aggregation with pathogens are considered desirable characteristics of p...
Sustainable lithium-ion battery separators based on poly(3-Hydroxybutyrate-Co-H...
Barbosa, J. C.; Correia, Daniela Maria Silva; Fidalgo-Marijuan, A.; Gonçalves, R.; Fernandes, M.; de Zea Bermudez, V.; Silva, M. M.; Lanceros-Méndez, S.To address the environmental issues related to lithium-ion batteries, environmentally friendlier separators based on poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) membranes are prepared by electrospinning. Cobalt ferrite (CFO) fillers can be incorporated to improve the electrochemical properties of the membranes and it is shown that fiber orientation and CFO filler addition have no relevant effect on the phys...
Lithium-based battery systems: Technological and environmental challenges and o...
Costa, C. M.; Barbosa, J. C.; Gonçalves, Renato Ferreira; Ferdov, S.; Lanceros-Méndez, S.The efforts of decarbonization and reduction of greenhouse gases emissions are among the most important agendas of the United Nations. Many countries adopted those objectives by enacting internal policies and increasing the share of renewable energies and thus contributing to the reduction of fossil fuels dependency. Thus there is an increasing interest in the development of efficient energy storage systems, su...
Potential of Akkermansia muciniphila DSM 22959 and Faecalibacterium duncaniae D...
Machado, D.; Vedor, R.; Fonseca, M.; Bento, M.; Barbosa, J. C.; Almeida, D.; Andrade, J. C.; Gomes, A. M.Introduction: In the last years, human intestinal bacteria, including Akkermansia muciniphila and Faecalibacterium duncaniae, have emerged as next generation probiotics to be incorporated in foods or delivered in pharmaceutical forms. Despite their multiple health benefits, the inhibitory properties of these probiotics against pathogenic colonization remain poorly studied, mainly due to difficulties in their cu...
