Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating

Advanced Materials, EarlyView.
This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

Advanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

Combinatorial Screening for Europium Induced Defect Engineering in Titania Anodic Memristors

Advanced Materials Interfaces, EarlyView.
A Ti‐Eu thin‐film combinatorial libary (3‐17 at.% Eu) was fabricated by co‐sputtering and anodisation. Systematic screening revealed forming‐free memristors with analog switching, with compositions between 7‐17 at.% Eu showing improved endurance and multilevel resistive states.
