Enhancing Stability of Microwave‐Synthesized Cs2SnxTi1‐xBr6 Perovskite by Cation Mixing
This research introduces a microwave radiation synthesis technique for synthesizing Cs2SnxTi1‐xBr6 lead‐free double perovskite powders. By incorporating Sn4+ cations, the stability of the material is improved, particularly at elevated temperatures and outside conditions.

In this study, Merkoçi and his research group present a polymer‐based synthesis to enhance the stability of Prussian blue (PB) nanoparticles. The resulting PB‐infused catalytic hetero‐interface architecture (PB‐CHIA) achieves complete two‐dimensional (2D) and three‐dimensional (3D) substrate coverage (glassy carbon and laser‐induced graphene electrodes)
