One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...
