Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

Advanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Advanced Functional Materials, EarlyView.
An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Highly Stable Ion‐Exchange Doping of Organic Semiconductor Single Crystals for Reliable Flexible Sensors

Advanced Functional Materials, EarlyView.
Stable ion‐exchange doping of organic semiconductor single crystals is demonstrated using bulky hydrophobic anions. Electrical conductivity is significantly enhanced and maintained under ambient air and elevated temperatures, while intrinsic strain sensitivity remains intact over 100 000 strain cycles. The approach highlights the critical role of anion

Thickness‐Dependent Skyrmion Evolution in Fe3GeTe2 During Magnetization Reversal

Advanced Functional Materials, EarlyView.
Thickness‐ and field‐dependent magnetic domain behavior in 2D van der Waals Fe3GeTe2 is studied using Lorentz TEM and micromagnetic simulations. A patch‐like domain phase evolves from skyrmions during magnetization reversal, and step edges between thickness regions act as pinning sites.

Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

Advanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

Advanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...
