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 ...

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.

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 ...

NOVEL HUMAN HAIR DYES III Human Hair Dyeing by Leuco-naphthazarin
Leuco-naphthazarin dyes white human hair fibers in an aqueous solution under the exceedingly mild conditions without any reducing agents and strong alkali in a dye bath at room temperature. The color development can be achieved without any oxidants. The dyeability remarkably increased by an addition of benzyl alcohol.
