Poly(vinylidene fluoride) (PVDF) and MOF-808-based separators for lithium-ion batteries (LIBs) have been prepared fully characterized in terms of morphological thermal properties, electrolyte uptake, retention, surface hydrophilic characteristics. The effect PVDF/MOF-808 on the electrochemical performance LIBs has evaluated. membranes exhibit a well-defined porous structure with uniform distribution interconnected macro- to mesopores. inclusion Zr-based MOF nanoparticles increases porosity...
Composites based on epoxy/graphene oxide (GO) and epoxy/reduced graphene (rGO) were investigated for thermal-mechanical performance focusing the effects of chemical groups present nanoadditive-enhanced surfaces. GO rGO obtained in study have been characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS), powder diffraction (XRD) demonstrating that materials with different oxidation degrees obtained. Thereafter, GO/epoxy rGO/epoxy nanocomposites successfully...
Desiccation-tolerant plants are able to withstand dehydration and resume normal metabolic functions upon rehydration. These can be dehydrated until their cytoplasm enters a 'glassy state' in which molecular mobility is severely reduced. In desiccation-tolerant seeds, longevity enhanced by drying lowering storage temperature. these conditions, they still deteriorate slowly, but it not known if deteriorative processes include enzyme activity. The stability of photosynthetic organisms less...
Metal chelators and porous sorbents are two of the forefront technologies applied for recovery separation hazardous and/or valuable metal ions from aqueous solutions (i.e., polluted water sources, metal-rich mining wastewaters, acid leachates, so forth). The transfer coordination functions to chemically stable host materials had only limited success far. Here, we report installation natural acids malic acid, mercaptosuccinic succinic fumaric citric acid) amino histidine, cysteine,...
Triple-shape memory polymers are developed by blending and crosslinking two semicrystalline (poly(cyclooctene), PCO, polyethylene, PE) towards creating pronounced segregated crystalline domains within a covalently crosslinked network. The key thermo-mechanical properties of series polyalkenamer polyolefin based polymer blends characterised using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) dynamic mechanical thermal (DMTA). Furthermore, the versatile multi-shape...
MDI and TDI based polyurethanes with tunable mechanical shape memory performance.
Shape‐memory polyurethanes (SMPUs) represent a highly interesting class of materials due to their applications in different sectors such as biomedical, textile, and aerospace. Moreover, it is possible synthesize variety with molecular architectures just choosing properly the chemical structure components. In this work, described influence soft segment on thermomechanical properties shape memory behavior polyurethanes. The synthesis, based two‐step polymerization, was prepared by two...
In this work, thermoresponsive shape-memory polyurethane (SMPU) fibers were produced by melt spinning from different SMPU pellets. Afterwards, the knitted fabric samples prepared obtained fibers. Some of SMPUs used synthesized previously in our laboratory whereas a commercial one, named DIAPLEX MM4520, was also evaluated order to carry out comparative studies. All characterized techniques, such as thermogravimetric analysis, differential scanning calorimetry, dynamic mechanical analysis and...
Two of the main factors controlling activity and selectivity metal sites within MOF-like copper metalloenzymes are: (i) their coordination environments, (ii) number connectivity ions at active site ( i.e. , nuclearity).
The extensive use of polymers in the medical field has facilitated development various devices and implants, contributing to restoration organ function. However, despite their advantages such as biocompatibility robustness, these materials often face challenges like bacterial contamination subsequent inflammation, leading implant-associated infections (IAI). Integrating implants effectively is crucial prevent colonization reduce inflammatory responses. To overcome major issues, surface...
Covalently crosslinked semi-crystalline polyalkenamer-based shape memory polymers (SMPs) were prepared and characterized. Thermal thermo-mechanical properties of thermo-sensitive manufactured by melt compounding investigated, features demonstrated. For remote activation recovery properties, electromagnetic inductive heating a series iron-based ferromagnetic microparticles was evaluated for subsequent incorporation into polymeric matrix. The capacity micro-sized iron-filled polyalkenamers...
The photoprotective mechanisms of desiccation tolerance and freezing their relation to molecular mobility (cell vitrification) were assessed in a single model: the exceptional subalpine resurrection plant Ramonda myconi . Dehydrated leaves showed drop maximal photochemical efficiency PSII ( F v / m ) accompanied by synthesis zeaxanthin (Z), even dark, which was limited cell vitrification after complete desiccation. recovery severe drying treatment (7 days at 50% relative humidity) confirmed...
Lichens can withstand extreme desiccation to water contents of ≤ 0.1 g H2O g-1 DW, and in the desiccated state are among most extremotolerant organisms known. Desiccation-tolerant life-forms such as seeds, mosses lichens survive 'vitrification', that is transition their cytoplasm a 'glassy' state, which causes metabolism cease. However, our understanding mechanisms tolerance hindered by poor knowledge what reactions occur state. Using Flavoparmelia caperata model lichen, we determined at...
