GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

open access: yesAdvanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Dual‐Surface Reaction Enabled Organic–Inorganic Hybrid Photodiodes for Faint Light Detection and Imaging

open access: yesAdvanced Functional Materials, EarlyView.
This work proposes a dual‐surface reaction strategy to optimize the interfacial contacts in organic–inorganic photodetectors. 1,4,5,8,9,11‐hexaazatriphenylene hexacarbonitrile (HAT‐CN) and ytterbium layers are designed to react with the Si surface, thus minimizing noise.

Spatially Resolved Click Patterning of Dyes on Graphene for 2D Hybrids with Regiotunable Fluorescence

open access: yesAdvanced Functional Materials, EarlyView.
Well‐structured graphene hybrid architectures featuring spatially resolved fluorescent properties represent a promising but so‐far elusive synthetic target. A robust and straightforward method for fabricating well‐organized graphene‐dye hybrid nanoassemblies through a combination of reductive patterning and conventional click chemistry is presented ...
