Transforming the Poison Effects of Water Vapor into Benefits Over Adjustable Dual Acid Sites for Stable Plasma‐Catalysis

open access: yesAdvanced Science, EarlyView.
YxMnyOx+2y catalyst provides dual active sites of Lewis acid (Y3+) and Mn for the co‐adsorption of H2O and O3, and the fast dissociation of adsorbed H2O to surface *OH. Then, a newly OH‐accompanied pathway for O3 decomposition is formed, transforming H2O to active ·OH radical, with the assistance of high energy electrons in the plasma.

Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

open access: yesAdvanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

Electric Field‐Driven Conformational Changes in Molecular Memristor and Synaptic Behavior

open access: yesAdvanced Science, EarlyView.
Self‐assembled monolayers (SAMs) based molecular device is used for the emulation of synaptic functions. The device operates with a novel switching mechanism via incoherent charge transport, inducing conformational changes. With a low energy consumption (8.0 pJ µm−2), the system shows promise for neuromorphic computing, offering potential in low‐energy,

Aromaticity‐Dependent Memristive Switching

open access: yesAdvanced Electronic Materials, EarlyView.
The article describes a resistive switching mechanism based on the creation of virtual filaments. Research consists of experimental and theoretical data supporting the theory that resistance of the memristor can be modulated by a redox‐induced aromaticity change of a working material.
