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 ...

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3
Advanced Functional Materials, EarlyView.Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors
Advanced Functional Materials, EarlyView.A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...

Ethiopian Journal of Science and Sustainable Development, 2019 A novel tunable red- to yellow- emitting phosphor,(Ca4-x-y-zBaySrz)(PO4)2O:xEu2+is reported that displays a broad emission from 500 to 800nm, and its emission can be adjusted from red to yellow by changing Ba2+ and Sr2+ doping concentration. X-ray powder
