Analysis of the Degradation of Thermochromic Sensors in Electrical Devices
Journal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.This study examines the degradation of microencapsulated leuco thermochromic pigments, both pure and embedded in epoxy, under thermal, cyclic, and QUV aging. UV radiation is the main factor causing irreversible loss of thermochromism due to microcapsule damage and solvent loss, while thermal exposure produces minor effects.

Advanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.The porous HMC selectively captures cationic dyes (MB and MG) from contaminated water, transforming dark, dye‐laden effluent into clean water. ABSTRACT Our investigation explores the exclusion of two health‐risk cationic dyes (e.g., Methylene Blue (MB) and Malachite Green (MG)) using a novel hydrazone‐modified cellulose (HMC) adsorbent synthesized via ...

Advanced Photonics Research, Volume 7, Issue 3, March 2026.The holographic recording performance of the photopolymerizable hybrid sol–gel is enhanced by optimizing photoinitiating systems based on boron dipyrromethene dyes. Two‐ and three‐component type‐II photoinitiating systems are employed, and their photopolymerization efficiency is evaluated through holographic patterning at 532 nm.

Advanced Sensor Research, Volume 5, Issue 3, March 2026.ABSTRACT Profluorescent nitroxides (PFNs) have established themselves as powerful tools for monitoring oxidative processes and subcellular redox dynamics by reactive oxygen species (ROS). Their characteristic “off–on” behavior arises from the efficient, proximity‐driven quenching of covalently bound fluorophores by paramagnetic nitroxide radicals ...
