Diblock Copolymer Nanoparticles Act as Nanoreactors for the Synthesis of Sterically‐Stabilized Inorganic Oxide Particles in Non‐polar Media

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...

Exploring Local Structure in Iron Oxide Nanoparticles During Chemical Vapor Synthesis by in Situ and Operando X‐Ray Absorption Spectroscopy

Small Methods, EarlyView.
In situ and operando XAS is used to probe nanoparticle formation during chemical vapor synthesis, where particles form in the gas phase under high‐temperature conditions. XANES reveals dynamic changes to the oxidation states while EXAFS indicates local structural variations under in situ probing conditions.

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

Periodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, Volume 38, Issue 61, 2 November 2026.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Orientation‐Dependent Surface Stoichiometry and Electronic Properties of ZnFe2O4 Thin Film Photoanodes

Israel Journal of Chemistry, Volume 66, Issue 6, November 2026.
Crystallographic orientation strongly influences the surface stoichiometry and interfacial electronic behavior of ZnFe2O4 thin film photoanodes grown by pulsed laser deposition. The (111) orientation exhibits greater Zn depletion, Fe enrichment, rectifying local current–voltage behavior, and a more positive water‐oxidation onset potential than the (110)
