Summary: This study successfully prepared strong PP/BF composites with excellent heat deflection temperature and enhanced impact performance, which were improved as the BF content increases. The interfacial bonding properties between BF and PP were significantly improved by PP grafted with maleic anhydride (PP-g-MAH), due to the reaction of maleic anhydride polar groups with the hydroxyl groups on the BF surface. The incorporation of PP-g-MAH led to significant improvements in tensile strength, flexural strength, impact strength, crystallization properties, rheological behavior, and thermal stability of the composites, contributing to the refinement and densification of cellular structure.

Summary: The incorporation of talc reduces the stiffness of composites, while the addition of graphene oxide and SEBS-g-MAH significantly improves the mechanical and thermal properties of ABS polymer matrix. ABS/talc composites prepared through melt mixing showed increased tensile strength, flexural strength, and flexural modulus, as well as comparable impact strength to ABS. The addition of GO and SEBS-g-MAH also provided higher thermal stability for both composites with and without talc.

Summary: High-strength, dimensionally-stable, moisture-absorbing, and heat-insulating materials are crucial for building safety and human comfort. Wood is commonly used in construction due to its natural moisture regulation and insulation properties, but its low strength and flammability present safety hazards. This study presents a simple method to create an organic-inorganic hyperbranched structure in poplar wood (WSi-Al-EP). The resulting composite wood material demonstrates high strength, stability, as well as improved shortcomings of traditional inorganic-modified materials, and exhibits resistance to heat and combustion, making it suitable for use in wooden building structures.

Summary: This review paper examines ten current ceramic radome materials under research and development and provides a comprehensive overview of available high temperature and high frequency data from literature. An examination of metamaterials for radio-frequency transparent radomes is given and our preliminary experimental results of a high-temperature metamaterial design are presented. The next-generation hypersonic vehicles' radome temperatures will exceed 1000 degrees C and speeds will exceed Mach 5. An ideal radome material will have a high flexural strength, low dielectric constant and loss tangent, and high resistance to thermal shock and corrosion. The microstructural effect on the dielectric and mechanical properties and the effects of environmental factors such as rain are discussed. The impact of metamaterial structure on key radome factors such as boresight error, gain, and polarization is examined. After examining the associated benefits with the use of metamaterials, our preliminary results for a potential high-temperature metamaterial design are presented.

Summary: The researchers demonstrate that cutinases are highly potent enzymes that can completely decompose PBAT films in 48 hours. By applying a double mutation strategy, the engineered cutinases exhibit higher decomposition rates and produce TPA as a major end-product, which is beneficial for the future recycling economy. The crystal structures of wild type and double mutation of a cutinase from Thermobifida fusca are solved, elucidating their substrate-binding modes and proposing the mechanism of cutinase-mediated PBAT degradation.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.
