New Hybrid Nanocomposite Films for Optical Diagnostics and Optical Temperature Sensing: Synergy Among α‐Synuclein, Gold and Upconverting Nanoparticles

open access: yesSmall, EarlyView.
Gold and upconverting nanoparticles coated with alpha‐synuclein were exploited to produce a quasi‐monolayer hybrid film. The film was then characterized, and its behaviour as a primary optical nano‐thermometer was studied. The film was also used in a proof‐of‐concept study of image‐based optical nanothermometry exploiting a home‐built up‐conversion ...

To Dye or Not to Dye: Unraveling the Impact of Surface Chemistry on Cerium Oxide Nanoparticles–Cell Interactions

open access: yesSmall Science, EarlyView.
Fluorescent dye labeling enables nanoparticle imaging but may subtly alter their surface chemistry and biological behavior. This study compares dye‐labeled and unlabeled cerium oxide nanozymes, revealing changes in cellular uptake kinetics without affecting their final intracellular fate. Combined fluorescence and label‐free electron microscopy imaging

Rapid Mechanochemical Synthesis of Oxyhalide Superionic Conductor: Time‐Resolved Structural Evolution

open access: yesSmall Methods, EarlyView.
Time‐resolved synchrotron X‐ray scattering coupled with mechanochemical synthesis reveals the structural evolution of oxyhalide superionic conductors. Oxygen incorporation governs reaction kinetics, amorphization, and microstructural transformations, while enabling efficient Li‐ion diffusion. This study highlights critical correlations between reaction

Quantifying the Full Damage Profile of Focused Ion Beams via 4D‐STEM Precession Electron Diffraction and PSNR Metrics

open access: yesSmall Methods, EarlyView.
Four‐dimensional scanning transmission electron microscopy (4D‐STEM) is used to acquire multiple convergent beam electron diffraction (CBED) patterns around focused ion beam (FIB) dwelled spots. Peak signal‐to‐noise ratio (PSNR) analysis, following calibration with well‐known implantation dose squares, enables full quantification of the FIB profile ...

Two‐Stage Isothermal Transformation of Austenite into Nanobainite in a Chemically Inhomogeneous Medium‐Alloy Steel Containing 0.5 wt% C

open access: yessteel research international, EarlyView.
The effect of chemical inhomogeneity on the microstructure and properties of nanobainitic steel is investigated. A two‐stage isothermal heat treatment that produced a more uniform microstructure is designed. The first‐stage temperature is higher than the MS of depleted bands; conversely, the second‐stage temperature is lower than the first‐stage ...
