Biocompatible polymeric microparticles produced by a simple biomimetic approach
Costa, A. M. S.; Alatorre-Meda, Manuel; Oliveira, N. M.; Mano, J. F.The use of superhydrophobic surfaces to produce polymeric particles proves to be biologically friendly since it entails the pipetting and subsequent cross-linking of polymeric solutions under mild experimental conditions. Moreover, it renders encapsulation efficiencies of ∼100%. However, the obtained particles are 1 to 2 mm in size, hindering to a large extent their application in clinical trials. Improving on ...
Electrochromic devices incorporating biohybrid electrolytes doped with a lithiu...
Fernandes, M.; Leones, Rita Daniela Barros; Costa, A. M. S.; Silva, Maria Manuela; Pereira, S.; Mano, J. F.; Fortunato, E.; Rego, R.The sol-gel method was employed in the synthesis of di-urethane cross-linked poly( caprolactone) (PCL(530)/siloxane biohybrid ormolytes incorporating either a mixture of lithium triflate (LiCF3SO3) and the ionic liquid (IL) 1-ethyl-3-methyl imidazolium tetrafluoroborate ([Emim]BF4), or solely with [Emim]BF4 or LiCF3SO3. The ormolyte doped with [Emim]BF4 is thermally more stable and exhibits higher ionic conduc...
Bombyx mori Silk Fibers: An outstanding family of materials
Pereira, R. F. P.; Silva, Maria Manuela; de Zea Bermudez, VerónicaDesigning novel multifunctional materials from natural resources is a challenging goal that has increasingly attracted researchers. Recently, the great potential of silk fibers has been recognized. The target readers for this review are researchers from different backgrounds (i.e., non-specialists in silk research) with special interests on the physical–chemical characterization of silk fibers, since their know...
Lithium-doped silk fibroin films for application in electrochromic devices
Pereira, R. F. P.; Sentanin, F.; Pawlicka, A.; Silva, Maria Manuela; Bermudez, Verónica ZeaSilk fibroin (SF) is a commonly available natural biopolymer produced in specialized glands of arthropods, with a long history of use in textile production and also in health cares. The exceptional intrinsic properties of these fibers, such as self-assembly, machinability, biocompatibility, biodegradation or non-toxicity, offer a wide range of exciting opportunities [1]. It has long been recognized that silk ca...
Superhydrophobic surfaces as a tool for the fabrication of hierarchical spheric...
Costa, A. M. S.; Alatorre-Meda, M.; Álvarez-Lorenzo, C.; Mano, J. F.Hierarchical polymeric carriers with high encapsulation efficiencies are fabricated via a biocompatible strategy developed using superhydrophobic (SH) surfaces. The carries are obtained by the incorporation of cell/BSA-loaded dextran-methacrylate (DEXT-MA) microparticles into alginate (ALG) macroscopic beads. Engineered devices like these are expected to boost the development of innovative and customizable syst...
Smart windows prepared from Bombyx mori silk
Pereira, Rui Francisco Gonçalves Pinto Fernandes; Sentanin, Franciani; Pawlicka, Agnieszka; Gonçalves, M. Cristina; Silva, Maria ManuelaWe introduce a bio-inspired strategy for the synthesis of green polymer electrolytes (PEs) which relies on the use of silk fibroin (SF). The two series of PEs prepared, doped with lithium bis(trifluoromethanesulfonyl)imide (SF@LiTFSI) or lithium tetrafluoroborate (SF@LiBF4) and incorporating glycerol, exhibited outstanding filmogenic properties, very high transparency and suitable adhesion to glass substrates. ...
Di-ureasil hybrid electrolytes incorporating a new proton ionic liquid
Cardoso, Marita A.; Leones, Rita Daniela Barros; Rodrigues, Luísa Cidália Guimarães; Fernandes, Mariana; Figueiredo, Filipe L.; Nunes, Sílvia C.The protic ionic liquid (PIL) N-butylimidazolium trifluoromethanesulfonate ([BIm][TfO]) was obtained for the first time and incorporated into a sol-gel derived di-ureasil matrix with a concentration of X = 5, 10 and 30 %, where X is the ratio of the mass of PIL per mass of poly(oxyethylene) (POE). Four years after their synthesis, the resulting quasi-anhydrous electrolytes remained amorphous, homogeneous, flexi...
Three-mode modulation electrochromic device with high energy efficiency for win...
Cardoso, Morita A.; Pereira, Rui Francisco Gonçalves Pinto Fernandes; Pereira, Sonia; Concalves, Helena; Silva, Maria Manuela; Carlos, Luis D.A sustainable use of energy in buildings demands energy-efficient windows. A new design concept for electrochromic (EC) smart windows, easy to implement at the industrial level, is introduced here. It enables simultaneous control of visible and near-infrared (NIR) solar radiation, thus contributing to reduce heating and cooling loads especially in buildings located in areas experiencing wide daily temperature r...
