Summary: Addressing the issue of electromagnetic radiation requires effective electromagnetic wave absorbers. Coral-like Co/CoO nanoparticle/reduced graphene oxide (Co/CoO/RGO) hybrid aerogels were synthesized and showed advantages of porous interconnected framework, abundant heterogeneous interfaces, and integration of dielectric/magnetic units. The addition of Co(CO3)(0.5)(OH)center dot 0.11H(2)O (CCOH) and reduction temperature allowed for tuning of the electromagnetic parameters, resulting in optimal absorption capability with a reflection loss of -32.4 dB and effective bandwidth of 4.2 GHz. The aerogels also exhibited hydrophobicity and thermal insulation properties, making them suitable for harsh environments. The interface polarization in the aerogels contributed to the electromagnetic wave loss.

Summary: As microwave technology advances, the electromagnetic (EM) environment becomes more complex. EM wave absorbing materials are important in shielding technology to reduce and isolate EM interference. This study prepared high-entropy carbide powders and compared their properties with TaC and NbC. The high-entropy carbides showed improved absorption performance and (Zr0.2Ti0.2Hf0.2Nb0.2Ni0.2)C had the best performance with minimum reflection loss of -42.61 dB and maximum absorption bandwidth of 3.60 GHz. Different compositions of high-entropy carbides affected dielectric loss, magnetic loss, and their coupling effect, providing important insights for designing absorptive materials with ultra-thin and good conductivity.

Summary: In this study, a microwave-responsive supramolecular adhesive was developed through the construction of cross-linked networks based on the coordination interaction between iron oxide nanoparticles and a catechol-based polymer. The adhesive can be quickly and selectively heated by microwave irradiation, providing strong adhesion for thermolabile substrates with negligible thermal damage. It can bond firmly and reversibly with various plastic substrates and has excellent multiple reusability with almost no loss of adhesion strength after ten times reuse. This supramolecular adhesive shows great potential in microelectronics and fine chemical industry due to the strong penetrability of microwave heating.

Summary: The application of microwave absorption materials can effectively solve the increasing electromagnetic pollution by converting electromagnetic energy into thermal energy and/or other forms of energy. Ternary transition metal carbides/nitrides MAX phases, as a type of promising microwave absorption material, have layered structure and superior conduction loss capability. However, impedance matching and single polarization loss type pose obstacles to improving their microwave absorption performance. High-entropy engineering can address these problems simultaneously.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.

Summary: Faster heating rates and higher process temperatures can reduce the total process time while achieving the same degree-of-cure. Thermal analysis shows that thermoplastic interleaf particles melt at the recommended curing temperature. A short dwell at a lower temperature can prevent the mixing of thermoplastic particles and thermoset pre-polymer.
