Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells
Advanced Functional Materials, EarlyView.Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

Bounding the Lifetime of Target Tracking Sensor Networks
, 2006 We propose a novel model to formally define the lifetime of target tracking sensor network based on energy by considering the relationship between individual sensors and the whole sensor network, the importance of different sensors based on their roles ...

Advanced Functional Materials, EarlyView.Clusterization‐triggered emission is realized in dilute aqueous solution by introducing imine linkages into cellulose‐based luminophores. Imine functionalization creates O/N‐rich, hydrogen‐bonded clustered microenvironments that stabilize emissive states and restrict molecular motions. Luminescence is tunable by amine type and multiplicity.

Advanced Functional Materials, EarlyView.Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
