2D single-crystalline metal nanosheets are considered promising candidates for triboelectric nanogenerators (TENGs). Now, Researchers at Jeonbuk National University have developed a hierarchical porous copper nanosheet-based TENG that significantly improves triboelectric performance through a unique structural design. The proposed architecture provides integrated multifunctionality, including energy harvesting, electromagnetic interference shielding, and Joule heating, making it highly lucrative for next-generation wearable electronic devices.

Researchers have created a heavy-atom-free, twisted D–A–A–D molecule that self-assembles into crystalline nanofibers. These fibers show high light absorption and 72% singlet oxygen yield, enabling rapid visible-light-driven photooxidation. They are easily recovered by sedimentation and remain stable over multiple cycles, offering a new design for efficient, reusable solid-state photosensitizers.

An efficient and scalable strategy of surface reconstruction for all-inorganic CsPbBr₃ films was proposed and a way to fabricate high-performance solar cells is opened.

Scientists at the University of Connecticut have developed a handheld ‘pocket microscope’ that directly visualizes DNA and proteins in living cells without stains or labels. The system uses deep-ultraviolet light to map molecules with femtogram sensitivity, achieving 308-nanometer resolution across centimeter-wide areas. The device enables instant pathology diagnosis, identifies cancer cells, and maps brain neurons -- all while preserving samples’ natural state. This technology could transform medical diagnostics, from operating rooms to space missions.
