Advanced Functional Materials, EarlyView.High‐entropy perovskite nanofibers serve as robust and active bifunctional air electrodes in reversible protonic ceramic electrochemical cells. Their compositional complexity stabilizes the lattice, enriches oxygen vacancies, and accelerates surface exchange.

Joint power control for untrusted relay cooperation-based confidential communication
Tongxin xuebao, 2014 The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure ...

Advanced Functional Materials, EarlyView.Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Advanced Functional Materials, EarlyView.This work presents a continuous linear gradient catalyst layer design, a general strategy for improving membrane electrode assemblies across electrochemical devices. Fabricated via a dual‐nozzle spray coating method, the architecture controls the Pt/carbon ratio, ionomer content and ionomer type across the catalyst layer, enhancing proton conduction ...
