Detecting ammonia isn’t just about avoiding bad smells—it’s about safety. This gas can harm workers in factories, pollute the environment, and linger in poorly ventilated spaces. Traditional sensors often struggle because they either pick up ammonia too slowly or take too long to reset. A new approa
Covalent-organic frameworks, or COFs, are like the superheroes of the materials world. These materials are designed with specific molecular structures to perform amazing tasks, like detecting tiny amounts of ammonia (NH3) at room temperature. Imagine two COFs, β-keto-AnCOF and imine-AnCOF, which hav
Imagine tiny polymer particles filled with special dyes, called BODIPYs, that can change color and brightness based on temperature and ammonia levels. Scientists made four types of these BODIPYs and mixed them into two kinds of polymers: PMMA and TPU. They created films and tiny particles (micropart
