Summary: Membranes are crucial in gas separation for their low cost, energy efficiency, and durability. Researchers have developed a new concept to enhance selectivity of graphene-based membranes by depositing microislands of Pd and Ni on the support layer, enabling efficient separation of specific gases like H2 and CO2. This approach may offer a promising alternative for economical gas separation by selectively targeting individual gases in a membrane setting through adsorptive separation at room temperature.

Summary: High-damping rubber materials play a crucial role in achieving high-performance green tires by reducing noise and vibration, providing auto-braking, and increasing service life. However, the mismatched surface energy between non-polar and polar rubber materials hinders their interfacial interaction and compatibility. In this study, a multi-functionalization high vinyl polybutadiene rubber (MFHVBR)/ethylene-vinyl acetate rubber (EVM) blend was prepared through simple mechanical blending, enhancing the interfacial compatibility and van der Waals interaction. The optimized MFHVBR/EVM blends exhibited ultrahigh damping properties with a wide effective damping temperature range, covering the service temperature of tires, along with improved vulcanization efficiency and physical mechanical properties. This study provides a feasible pathway for developing low-cost and high-performance green tire tread rubber materials.

Summary: A hybrid fiber network was constructed in the char layer combining aramid fiber (AF) and carbon fiber (CF) in order to improve the ablative performance of EPDM-based insulators for Solid Rocket Motors. The best ablative performance was achieved at a 1:1 ratio of AF and CF, resulting in a 31% reduction in linear ablation rate compared to insulators filled with only AF. The formation of char layer with CF shielded at surface and AF consolidated inside was found to have a synergetic effect on ablation resistance.

Summary: This paper investigates the use of high infrared transparent polymer ultrahigh molecular weight polyethylene (UHMWPE) as a matrix for thermal insulation material. UHMWPE porous films with high porosity and hybrid pore structure were successfully prepared. The films exhibited low thermal conductivity and remarkable flexibility and hydrophobicity. The hybrid porous structure of the films simultaneously reduced heat conduction and gas-solid coupling effect, leading to significantly reduced thermal conductivity. The porous films hold great promise in thermal insulation protection and infrared stealth applications.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
