China has been developed into one of the most active regions in terms of both fundamental and applied research on magnesium （mg） and its alloys in the world from a solid base laid by its prominent metallurgist and materials scientists over the past decades. Nowadays, a large number of young-generation researchers have been inspired by their predecessors and become the key participants in the fields of mg alloys, which consequently led to the establishment of China Youth Scholar Society for magnesium Alloys Research in 2015. Since then, the first two China Youth Scholars Symposiums on mg Alloys Research had been held at Harbin （2015） and Chongqing （2016） China, respectively. A number of crucial research inter- ests related to fundamental and applied mg research were discussed at the conferences and summarized in this short perspective, aiming to boost far-reaching initiatives for development of new mg-based materials to satisfy the requirements for a broad range of industrial employments. Herein, four main aspects are included as follows： i） Plastic deformation mechanism and strengthening strategy, ii） Design and development of new mg-based materials, iii） Key service properties, and iv） New processing technologies.

Robust, ultra-flexible, and multifunctional mXene-basedelectromagnetic interference (EmI) shielding nanocomposite filmsexhibit enormous potential for applications in artificial intelligence,wireless telecommunication, and portable/wearable electronic *** this work, a nacre-inspired multifunctional heterocyclic aramid(HA)/mXene@polypyrrole (PPy) (HmP) nanocomposite paper withlarge-scale, high strength, super toughness, and excellent tolerance tocomplex conditions is fabricated through the strategy of HA/mXenehydrogel template-assisted in-situ assembly of PPy. Benefiting from the"brick-and-mortar" layered structure and the strong hydrogen-bondinginteractions among mXene, HA, and PPy, the paper exhibits remarkable mechanical performances, including high tensile strength (309.7 mPa),outstanding toughness (57.6 mJ m−3), exceptional foldability, and structural stability against ultrasonication. By using the template effect ofHA/mXene to guide the assembly of conductive polymers, the synthesized paper obtains excellent electronic conductivity. more importantly,the highly continuous conductive path enables the nanocomposite paper to achieve a splendid EmI shielding effectiveness (EmI SE) of 54.1 dBat an ultra-thin thickness (25.4 μm) and a high specific EmI SE of 17,204.7 dB cm2g−1. In addition, the papers also have excellent applicationsin electromagnetic protection, electro-/photothermal de-icing, thermal therapy, and fire safety. These findings broaden the ideas for developinghigh-performance and multifunctional mXene-based films with enormous application potential in EmI shielding and thermal management.
