Advanced Functional Materials, EarlyView.A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Experience of Transformer’s Inrush Current Modeling for the Purposes of Relay Protection
In case of transformer failure there is a high risk of losing part of power system, which can result in disruption for consumer power supply. This is main reason for power transformer protection requirement to be so high.

Advanced Functional Materials, EarlyView.A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Advanced Functional Materials, EarlyView.An effective strategy is developed to overcome the medium temperatures wear resistance degradation in refractory multi‐principal element alloys. By utilizing chemical short‐range ordering to trigger oxygen‐induced amorphization, a composite oxide structure is formed, which combines high hardness with robust stiffness.
