Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, EarlyView.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

Effect of Optical Illumination on Bubble Nanodomains

Advanced Functional Materials, EarlyView.
Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...

Performance Enhancement of Tin Chloride‐Incorporated Ferroelectric Polymer‐Based Artificial Synapse for Hardware Neural Networks

Advanced Functional Materials, EarlyView.
This paper proposes a highly efficient ferroelectric artificial synapse device based on an oxide semiconductor and SnCl2‐inserted P(VDF‐TrFE) gate dielectric layer. This FeFET significantly improved the synaptic performance due to the ion‐dipole interaction.
