Chemists Reveal Color-Shifting Molecule That Senses Temperature

Antti and Sami discovered that a light-responsive molecule called azobenzene changes color depending on temperature when it interacts with acid. Their experiments and computer models showed that colder conditions shift the balance between protonated and non-protonated forms, opening up possibilities for simple temperature sensors. This collaboration highlights how lab work combined with theory can turn basic chemistry into practical tools. Read more...
