Summary: The scientific community is focusing on replacing meat-based foods with new plant-based matrixes. Quinoa, as a pseudo-cereal, has drawn interest due to its amino acid profile and bioactive properties. This study found that proper QF-based gels can be obtained at specific QF concentrations and temperatures.

Summary: Accurate determination of cure-dependent viscoelastic properties is crucial for the processing and use of epoxy resin-based materials and structures. Despite frequent discussions in literature and practice, there are currently no standardized guidelines available. Therefore, a comprehensive review was conducted to provide holistic test protocols that consider the interaction between curing process, device capabilities, and the measured viscoelastic phenomena.

Summary: The influence of multi-walled carbon nanotubes (MWCNTs) on the thermal, mechanical, wetting properties, and rheological behavior of poly(ethylene-co-vinyl acetate) (EVA)/acrylonitrile-butadiene rubber nanocomposites was investigated. It was found that the addition of MWCNTs improved the solid surface free energy, work of adhesion, spreading coefficient, and Girifalco-Good's interaction parameter, while reducing the contact angle and interfacial free energy. The nanocomposite with 1 wt% nanofillers exhibited the highest tensile strength and toughness. Furthermore, the relaxation ratio and relaxation rate index decreased with increasing carbon nanotubes (CNTs) concentration. The increment in MWCNTs loading led to an increase in the yield stress of the molten materials according to a quadratic equation. The analysis also showed that the crystallization process was triggered at a slightly higher temperature with the introduction of CNTs, while the melting point and nucleation rate decreased noticeably with the increase in nanofillers content.

Summary: This study investigates the effects of adding very small amounts of fumed silica on the morphology, rheological and mechanical behavior of polypropylene nanocomposites, as well as their photo-oxidation behavior. The presence of silica nanoparticles reduces the viscosity of the matrix, improves mechanical properties, particularly the elastic modulus and tensile strength, and enhances the photostability of the polypropylene matrix. The difference in properties between the nanocomposites with different silica content is relatively small, suggesting a nonlinear relationship between the amount of silica and the measured properties.

Summary: Nanocomposites of PMMA and EVA with varying MWCNT content were prepared, with optimal mechanical properties achieved at 5 wt% MWCNT and significant increase in electrical conductivity at 2.5 wt% MWCNT. Rheological characterization showed an increase in normalized relaxation time up to 5 wt% nanofiller, followed by stability at higher MWCNT amounts.

Summary: This research investigates the chemical, thermal, mechanical, thermo-mechanical properties, and fractography of sandwich composites made from E-glass-reinforced isophthalic polyester with PVC foam as a core by hand. The results show that the sandwich composite with double layers of E-glass exhibits superior mechanical and thermal properties. Examination of the fractured surfaces reveals the structure characteristics of the composites.

Summary: This study investigated the properties of biodegradable composites reinforced with hazelnut shell powder. The results showed that the incorporation of hazelnut shell significantly increased the viscosity, promoted crystallization properties, and improved thermomechanical stability of the composites. However, a high content of hazelnut shell adversely affected the processability in injection molding.

Summary: The study found that nonlinear polymers can significantly alter the mechanical properties of polymer nanocomposites, and attractive NPs in highly branched matrices can markedly slow down the average dynamics of the polymer. Additionally, the nanoscale dynamics of particles in compact nonlinear matrices show strong decoupling from bulk viscoelasticity.

Summary: This study reports on the rheological properties of organic gels prepared from TATA and OPVOH molecules. It is found that TATA/PVC ternary gels generally exceed the Voigt upper limit, possibly due to a desolvation process occurring in PVC fibrils. Furthermore, the conducting properties strongly depend on the solvent type but are not significantly altered when PVC is present.

Summary: With the increase in layer thickness, the tensile strength of printed specimens decreased, but the raster angle did not have a significant effect on the properties. In samples containing 3% MWCNT, nanoparticles were reasonably dispersed throughout the matrix.

Summary: This study introduced an ionic liquid, 1-ethyl-3-methylimidazolium acetate, into carbon black/natural rubber nanocomposites to regulate the microstructure and viscoelasticity. The results showed that the ionic liquid could enhance vulcanization, improve polysulfide crosslinking bonds, and promote carbon black dispersity without significantly affecting crosslinking density. Furthermore, the ionic liquid weakened the Mullins effect by reducing dissipation and softening energies, and at a certain carbon black volume fraction, it improved tensile strength and extensibility while weakening the Mullins effect simultaneously. This investigation provides insight into tailoring the elasticity and dissipation of vulcanizate nanocomposites.

Summary: In this study, graphene sheets were exfoliated from graphite inside a polymer matrix solution in one step, leading to a cost-effective and efficient method for mass production. The maximum values for dielectric permittivity, dielectric loss, and alternating current electrical conductivity were observed at 10 minutes of exfoliation time. The elasticity modulus peaked at 30 minutes of exfoliation time, indicating optimal properties for the graphene-loaded polymer films.
