Advanced Science, EarlyView.The universality of the landscape‐flux theory with the mode expansion method for analyzing spatial patterns is illustrated by applying it to vegetation patterns in semi‐arid ecosystems. The framework quantifies global dynamics and most probable transition pathways between ecosystem states under random forcing.

Advanced Science, EarlyView.≈1 nm thick amorphous layer with a higher oxygen concentration is formed on the surfaces of pristine P‐doped NiFe2O4 and activated NiFe2O4. Such surface layer is thought to significantly promote the charge transfer kinetics compared to the oxyhydroxide layer grown on Ni1.5Fe1.5O4 during the oxygen evolution reaction. Abstract Optimizing electrocatalyst

Ohmic Response in BiFeO3 Domain Walls by Submicron‐Scale Four‐Point Probe Resistance Measurements
Advanced Electronic Materials, EarlyView.Lateral transport measurements of multiferroic domain walls (DWs) in BiFeO3 thin films employing a novel, lithography‐free method are presented. Using a submicron‐scale multi‐point probe (MPP), ohmic DW conduction behavior is demonstrated, including the first collinear, four‐point resistivity value of a single DW, free of contact resistances.

Mechanism of Fixed Pattern Noise of Micro‐Channel Plate Focusing on Cross‐Section of Single Channel
Advanced Electronic Materials, EarlyView.The movement of secondary electrons to the phosphor screen after avalanche in microchannel plate (MCP) is influenced by the single channel cross‐sectional shape. The secondary electron beam emitted from MCP channels with different cross‐sectional shapes affects the energy and position upon striking the phosphor screen, directly impacting FPN (Fixed ...
