Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors

open access: yesAdvanced Functional Materials, EarlyView.
Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Tuning the Organic Electrochemical Transistor (OECT) Threshold Voltage with Monomer Blends

open access: yesAdvanced Electronic Materials, EarlyView.
A novel approach is introduced to modulate the threshold voltage of organic electrochemical transistors (OECTs) through the copolymerization of monomers with differently charged sidechains. We demonstrate that blends of water‐soluble tri‐thiophene compounds with anionic and zwitterionic sidechains form compositionally uniform aggregates at different ...
