Ultrasonication‐Induced Iridium Single‐Atom Decoration on Anodized NiO Nanosponge Electrocatalyst for Enhanced Oxygen Evolution Reaction

Small, EarlyView.
A facile one‐pot sonochemical strategy generates Ir single‐atom catalysts on nanostructured NiO for enhanced oxygen evolution reaction performance. Surface defects enable strong anchoring of Ir single atoms on NiO. The NiO‐0.5 Ir catalyst exhibits significantly improved activity, supported by structural, spectroscopic, and electrochemical analyses ...

Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

Small, EarlyView.
Perovskites are emerging as catalysts for acidic oxygen evolution in proton exchange membrane water electrolyzers. This manuscript focuses on catalyst behavior under device‐relevant conditions, highlighting surface reconstruction, elemental utilization, and membrane electrode assembly performance. By linking materials design with electrolyzer operation,

Mitigating Residual FAI for Air‐Stable FAPbI3 LEDs

Small, EarlyView.
Treating FAI‐rich FAPbI3 perovskite films with the multifunctional molecule DEAET, combining a protonated amine and a thiol group, effectively regulates residual surface organic‐halide species, suppresses non‐radiative recombination, and modifies interfacial energetics. The resulting near‐infrared perovskite LEDs achieve 14% external quantum efficiency

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Synthesis of Chiral Gold Nanostructures on Gold‐Coral‐Coated Transparent Conductive Oxide Substrates via [AuCl4]– and Cysteine Interactions for Enhanced Chiral Sensing

Small, EarlyView.
We developed hierarchical chiral Au nanostructures on Au coral structures on transparent conductive oxide substrates using only electrochemical methods. By controlling the interaction between [AuCl4]– and cysteine, we successfully tuned the morphology and circular dichroism of the resulting Au nanostructures.

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

Smart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.
