Context‐Dependent Radioenhancement by Platinum Nanoparticles Under Conventional and Ultra‐High Dose‐Rate “FLASH” Radiotherapy

Small, EarlyView.
Overview of the experimental workflow and main findings of the study investigating Pt‐NPs‐mediated radioenhancement under conventional 134 dose‐rate (CONV) and ultrahigh dose‐rate (UHDR) 9 MeV electron irradiation. Pt‐NP distribution and uptake were characterized in 4T1 spheroids and syngeneic tumor models.

Safeguarding the Photoluminescence of Silver Sulfide Nanocrystals in Biological Environments via Silica Shielding

Small, EarlyView.
Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Multielectron Charge Storage Enables Cascade Electrochemiluminescence in an Atomically Precise Silver Nanocluster

Small, EarlyView.
An atomically precise Ag6 nanocluster stores multiple electrons through sequential reduction reactions and releases the stored charge through successive emissive oxidation reactions with a benzoyl peroxide‐derived radical. This multielectron charge storage pathway enables an electrochemiluminescence cascade, producing a substantially more efficient ...

Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

Small, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...

Unveiling Hidden Patterns in Electrode‐Electrolyte Interphase Chemistry and Architecture Through Machine Learning‐Assisted Mass Spectrometry Analysis

Small Methods, EarlyView.
Electrode‐electrolyte interphases are critical for battery performance, yet their chemical, structural, and thickness heterogeneity are challenging to resolve. Machine learning applied to 3D TOF‐SIMS datasets reveals how individual chemical components shape interphase composition, spatial architecture, and local thickness variations.
