2D hybrid perovskite ferroelectrics have drawn great attention in the field of photodetection, because spontaneous polarization-induced built-in electric can separate electron-hole pairs, and makes self-powered photodetection possible. However, most perovskite-based photodetectors focused on detection visible light, only a few reports realized sensitive ultraviolet (UV) using wide bandgap perovskites. Here, ferroelectric PMA2PbCl4 monocrystalline microbelt (MMB)-based PDs are demonstrated....

Abstract Creating specific noble metal/metal‐organic framework (MOF) heterojunction nanostructures represents an effective strategy to promote water electrolysis but remains rather challenging. Herein, a electrocatalyst is developed by growing Ir nanoparticles on ultrathin NiFe‐MOF nanosheets supported nickel foam (NF) via readily accessible solvothermal approach and subsequent redox strategy. Because of the electronic interactions between nanosheets, optimized Ir@NiFe‐MOF/NF catalyst...

Our reveals conductivity TaAs features narrow Drude alongside conspicuous linear on frequency. The width peak decreases upon cooling, following $T^{2}$ which is expected for semimetals. Two components with distinct slopes dominate 5-K conductivity. A comparison between our experimental results theoretical calculations...
This article proposes an improved implicit model predictive current control (IMPCC) method for permanent magnet synchronous motor (PMSM) drives. Compared to the conventional MPC, proposed IMPCC has a much lower computational burden and thus is suitable real-time applications. Two-step optimization employed in this minimize cost function based on continuous set (CCS) while respecting constraints. Furthermore, uses incremental that eliminates flux linkage. Its strong parameter robustness...
Self-powered photodetectors (PDs) have the advantages of no external power requirement, wireless operation, and long life.
