Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites
Advanced Functional Materials, EarlyView.Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Nigerian journal of medicine : journal of the National Association of Resident Doctors of Nigeria, 2012 Swallowed foreign bodies in children are not a very rare occurence but most of these objects are blunt. Below is presented an unusual swallowed foreign body--a screw. The diagnosis was confirmed by a plain abdominal radiograph and the patient was managed conservatively.

Advanced Functional Materials, EarlyView.Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
Advanced Functional Materials, EarlyView.β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Advanced Functional Materials, EarlyView.This study demonstrates coherent control of 15N nuclear spins coupled to VB−${\text{V}}_{\text{B}}^{-}$ centers in isotope‐enriched hexagonal boron nitride. Selective addressing via spin‐state mixing enables Rabi driving, quantum gates, and coherence times exceeding 10 μs$\umu{\rm s}$.
