Summary: This study investigated the thermal behavior of a polymer with intrinsic microporosity (PIM-1) membrane using thermomechanical analysis and differential scanning calorimetry. It was found that the coefficient of thermal expansion (CTE) remained constant below 110 degrees C, with inflection points observed between 120-150 degrees C. The CTE after the inflection point was significantly influenced by the fabrication conditions and thermal history. Cooperative molecular motion was observed below 200 degrees C.

Summary: This research focuses on thermoplastic polyamide (PA6)-based composites reinforced with basalt and Kevlar fabrics. The stacking sequence of basalt and two types of Kevlar fabrics were altered to develop hybrid composites. Mechanical and thermomechanical properties of the developed samples were evaluated, including tensile, flexural, and impact strength tests, as well as thermogravimetric analysis and differential scanning calorimetry. Scanning electron microscopy was used to study the fracture and failure nature of the composites. The results showed that hybridization with basalt improved the mechanical performance and thermal stability of the composites using Kevlar fabric. The stacking order of the reinforcements could alter the thermomechanical characteristics. These novel hybrid composites have potential applications in high-load-bearing and high-temperature environments.

Summary: This study investigated the use of micro-nano rice husks (MNRH) fibers compounded with polylactic acid (PLA) to produce 3D-printed filaments. The addition of silane coupling agents improved the surface quality and enhanced the dispersing performance of the MNRH fibers in the composites. The treated composites exhibited improved thermal stability, crystallinity, and water resistance. Furthermore, the mechanical properties of the composites, including tensile strength and bending strength, were significantly enhanced. The findings suggest that the treated composites have great potential for use as environmentally friendly alternative materials in automotive interiors.

Summary: This study investigates the effects of different micro and nano AlN fillers on the electrical performances and thermal properties of hybrid composites at high temperatures. The results show that nano-fillers enhance the electrical performances but decrease the apparent mobility and activation energy of the composites. Additionally, a hypothetical mechanism is proposed to explain the charge carrier injection and transport of the composites at different temperatures.

Summary: This work presents the development of a bio-based polymer blend, PVA/CG, embedded with boehmite nanoparticles to enhance its structural, thermal, mechanical, and electrical properties. The presence of boehmite in the blend was confirmed through FTIR and XRD analysis. SEM images showed uniform dispersion of boehmite at 5 wt%. The addition of boehmite increased the thermal stability and electrical conductivity of the blend, while slightly decreasing the glass transition temperature. Tensile strength and hardness improved with the incorporation of boehmite, making the PVA/CG/boehmite films a potential substitute for flexible electronic and electrochemical devices.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
