Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes

Advanced Materials, EarlyView.
Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

Advanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

High Stability of Diketopyrrolopyrrole Polymer Transistors Under Aqueous Condition Toward Biosensing Platform

Advanced Materials Technologies, EarlyView.
We are reporting the first‐time investigation of DPP‐based Organic Field‐Effect Transistor (OFET) devices with high‐stability of signal response in both of ambient and aqueous conditions with PBS solution. ABSTRACT Diketopyrrolopyrrole (DPP)–based conjugated polymers show strong promise for electronic applications, including bioelectronic gas sensors ...
