Summary: A novel CaCu3Ti4O12-polyvinylidene fluoride composite with Cu-deficiency was prepared successfully through the molten salt-assisted method. The Cu-deficient CCTO exhibited higher dielectric constants than those without post-treatment at the same volume fraction. These composites have prospective applications in high-frequency regions and the high dielectric constants were attributed to the homogeneous dispersion and interfacial polarization of CCTO.

Summary: Multiple studies have reported on the structural, magnetic, and electrical properties of BiFeO3-Al2O3 nanocomposites prepared using the sol-gel method. The results showed that the composites had a bi-phase structure with the presence of impurity phases. The addition of Al2O3 nanoparticles led to a decrease in the dielectric constant, loss tangent, and ac conductivity. The electrical measurements followed Jonscher's universal power law and were dominated by the correlated barrier hopping mechanism.

Summary: The adhesion between polymer reinforced with TiC nanoparticles and steel surface is influenced by factors such as surface free energy, shape, amount, and size of particles, and reinforcement effects in causing cohesive or adhesive failure. Nanocomposites containing TiC nanoparticles outperformed microcounterparts in various physical, thermal, mechanical, and adhesive strength properties. The extent of adhesive failure decreased and cohesive failure increased with an increase in nano-particles, as validated by available models for nanocomposites.

Summary: In this study, an eco-friendly synthesis method was proposed for creating hybrid composites with ultralow dielectric properties for true 5G communication. The composites were made from aqueous aromatic polyimide polymers and dual-porous silica nanoparticles. The synthesis process involved the one-step polymerization of water-soluble poly(amic acid) in an aqueous solution, along with the functionalization of macroporous silica nanoparticles to ensure excellent dispersion stability. By varying the amount of dual-porous silica nanoparticles in the polyimide matrix, it was found that the addition of 5 wt% nanoparticles resulted in a composite with ideal dielectric properties and satisfactory mechanical characteristics.

Summary: In order to overcome the energy density limitation of supercapacitors, a high specific capacitance material was achieved by manipulating the nanostructure of FeS2. Nanosheet-assembled FeS2 (NSA-FeS2) was fabricated using a novel method. The as-prepared NSA-FeS2 and NSA-FeS2/polyaniline (PANI) composites showed specific capacitances of 763 and 976 Fg(-1), respectively, at a current density of 0.5 Ag-1. The capacitance retention of the NSA-FeS2/PANI composites was 49% when the current density was increased to 5 Ag-1.

Summary: In this study, a catalytic inverse vulcanization method based on trialkyl amines (TAAs) is introduced. The oleophilic alkyl chains of low-cost organic TAAs act as nucleophilic activators for efficient reactions, even at a low temperature of 110 degrees C. TAAs improve the reaction yield and thermal properties of the products, while suppressing the generation of toxic H2S gas. Furthermore, TAAs can be extracted and recycled, demonstrating their eco-friendly characteristics. This study expands the application range of sulfur-rich copolymers by utilizing TAAs to inverse vulcanize elemental sulfur with various unreactive crosslinkers.
