October 2024
Stanene (Sn)-based materials, with a graphene-like hexagonal structure, are now attracting considerable interest for potential applications in photoelectricity. However, the nonlinear optical properties of stanene remain largely unexplored. In this work, we prepared different sizes of stanene by liquid phase exfoliation and differential centrifugation methods, including two-dimensional (2D) Sn nanosheets (NSs) and zero-dimensional (0D) Sn nanodots (NDs).

Article Synopsis
- The growing interest in space exploration requires new radiation-resistant materials, with nonlinear optical materials being particularly limited in availability.
- Researchers studied newly created 2D bismuthene to see how well it performs in simulated space radiation conditions, finding it maintains its key optical properties even after exposure to harmful radiation.
- This study not only advances the understanding of 2D bismuthene's behavior under radiation but also sets the stage for optimizing such materials for future use in space technology.
A graphene oxide paper (GOP) was irradiated with 500 keV proton for total fluence of 2 × 10 cm to 2 × 10 cm in a ground-based irradiation simulator. The spacing of layer, surface chemical composition, structural defects, thermal conductivity and electrical property of the GOP before and after irradiation was measured. The results indicated that the spacing of layer decreased after irradiation.
