Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

open access: yesSmall, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.

Position Over Composition: Positional Isomerism Enables Encapsulation‐Independent Intrinsic Stability in a Conjugated Polymer

open access: yesSmall, EarlyView.
Repositioning side chains (para→meta) provides a composition‐invariant handle to program conjugated‐polymer chain geometry. The resulting worm‐like, kink‐suppressed conformation delivers >5× higher intrinsic photostability and enhanced resistance to energetic particle damage.

A Comprehensive Multimodal Study of La0.45Sr0.45TiO3 Structure as Matrix for the Exsolution Process: From the Average to the Local Scale

open access: yesSmall, EarlyView.
We present a multimodal, multiscale study of La0.45Sr0.45TiO3 combining experimental and computational approaches to probe its local structure. The results reveal A‐site ordering along [001] and loss of centrosymmetry driven by electrostatic effects.

Engineering Carbon Nanotube Quantum Well Defects With Recognition Tripeptides for Optical Detection of Extracellular Vesicles in Plasma

open access: yesSmall, EarlyView.
A three‐residue peptide bioconjugated onto a carbon nanotube quantum defect turns the near‐infrared emission of quantum defects into a reporter of integrins on intact extracellular vesicles, directly in human plasma. The sensor reveals that healthy fibroblast vesicles carry as much RGD‐binding integrin as cancer‐derived ones, an adhesion‐associated ...

Titanium Oxide Thin Films With Metal Nanodisks as Plasmonic Metamaterial Photocatalyst Sheets for IPA‐Assisted CO2 Reduction

open access: yesSmall, EarlyView.
Plasmonic metal nanodisks (Ag, Au, Pt, Pd) combined with TiO2 thin films were fabricated into periodic metamaterial photocatalyst sheets by using standard semiconductor methods. Under visible light, Pt/TiO2 and Pd/TiO2 achieved hydrogen and methane production from CO2 and water using isopropyl alcohol, demonstrating promising solar‐fuel production ...
