MXenes exhibit considerable potential for developing high-performance electromagnetic (EM) shielding and absorption materials operating across microwave and terahertz frequencies, due to their tunable surface chemistry and exceptional charge carrier transport properties. Nevertheless, a profound understanding and precise manipulation of their broadband attenuation mechanisms remain challenging. In this review, we first examine Ti₃C₂T_x MXene as a representative system to explore EM attenuation mechanisms through polarization and conductive loss models across microwave and terahertz bands. We then discuss tuning strategies, including component tailoring, interlayer regulation, film architecture, and dynamic modulation, which are supported by both classic and emerging studies, and evaluate their impact on attenuation performance. Finally, we outline future research priorities and development directions for MXene-based EM attenuation materials. By synthesizing recent advances, this review aims to establish the structure–property relationships in MXenes and to provide forward-looking insights for the field. ... Read more

This study aims to comprehensively investigate the rejuvenation efficiency of various self-developed compound rejuvenators on the physical, mechanical, and aging properties of aged bitumen, asphalt mortar, and mixture. The results revealed that the restoration capacity of vacuum distilled-oil rejuvenators on high-and-low temperature performance-grade of aged bitumen is more significant. In contrast, an aromatic-oil based rejuvenator is good at enhancing low-temperature grade and aging resistance. Moreover, the temperature and time of the curing conditions for mixing recycling of asphalt mixture were optimized as 150 °C and 120 min. Furthermore, the sufficient anti-rutting, structural stability, and moisture resistance of recycled asphalt mixture affirmed the rejuvenation efficiency of compound rejuvenators. ... Read more
