Spontaneous Nanocrystals/Amorphous MoS Film Induced by Fe Irradiation with Superior Irradiation Tolerance and Tribology Properties.

High-performance radiation-resistant lubricating materials (RRLMs) with nanostructures hold great promise for enhancing the irradiation tolerance because of their sinking effect of boundaries on defects. Despite recent advances, challenges remain in finding a nanostructure that exhibits both superior irradiation tolerance and excellent lubricant properties. Unlike traditional nanostructured composite materials that required complex predesign, herein, a MoS nanocrystals (NCs)/amorphous dual phase in subirradiation saturation (SIS) state was spontaneously formed during irradiation, exhibiting high irradiation resistance under the synergistic effect of "defect traps" by interfaces and edge dislocation.

Dielectric Matching by the Unique Dynamic Dipoles in Hybrid Organic/Inorganic Superlattices toward Ultrathin Microwave Absorber.

There is an urgent demand of ultrathin high-performance microwave absorbing materials (MAMs) in the electromagnetic protection field. However, minimizing thickness is challenging mainly due to dielectric mismatch at high permittivity from excessive dielectric loss, leading to strong reflection at 2-18 GHz. Here, a hybrid TaS /Co(Cp) superlattice is fabricated with alternating [TaS ] inorganic layers and [Co(Cp) ] organic layers.
