Oxidation‐Induced Internal Chemical Patterning in Copper–Gold Nanoalloys

open access: yesSmall, Volume 22, Issue 56, 8 October 2026.
Surface oxidation suppresses Au surface segregation and redirects Au transport to twin boundaries, replacing conventional core–shell formation with internal chemical patterning. Driven by Cu–Au mixing thermodynamics, defect‐mediated uphill diffusion creates alternating Au‐rich and Cu‐rich lamellae, revealing oxidation as a chemical pump for bulk ...

Programmable Porosity in Polymers via Microfluidic Templating and 3D Printing

open access: yesSmall Methods, Volume 10, Issue 20, 26 October 2026.
Fluid templating is a powerful way to produce porous polymers. Microfluidic technologies enable fine control over the dimension and packing of bubbles and droplets. Combined with additive manufacturing, microfluidic templating enables the creation of polymeric functionally graded porous materials in which both porosity and three‐dimensional geometry ...

Plasma‐Engineered Covalent Organic Frameworks With Tunable Electronic Structures for Selective Superoxide Generation

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
Atmospheric‐pressure microplasma enables the one‐step aqueous synthesis of covalent organic frameworks (COFs) while concurrently modulating their interfacial physicochemical and electronic characteristics. Linker‐regulated band structures, plasma‐induced surface functionalities, and accessible porous interfaces collectively favor superoxide‐dominated ...

Nanoparticle and Membrane Responses in Plasmonic Polymeric Vesicles Under Distinct Pulsed Laser Irradiation Regimes

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
This investigation combines experimental characterization with numerical modeling to reveal how laser parameters such as fluence and pulse duration influence the behavior of membrane‐incorporated photoexcited gold nanoparticles. This gives rise to distinct nanoparticle modifications and membrane response pathways ranging from localized permeabilization

Stress‐Programmed Microcrack Networks in Gallium–Carbon Nanotube Thin Films for Plasma‐Active and Electroresponsive Antibacterial Interfaces

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
Drying‐induced stress and rolling‐assisted sintering program hierarchical microcrack networks into ultrathin gallium–carbon nanotube (Ga/CNT) films. Crack‐bounded gallium microdomains preserve mechanically repairable conduction, while crack edges and junctions are proposed to localize the electric field: atmospheric plasma emission intensifies with ...
