Traveling waves are commonly observed in biological and synthetic systems, and recent discoveries have shown how silver colloids form traveling motion waves in hydrogen peroxide under UV light. In a new report now published in Science Advances, Xi Chen and a team of researchers in smart materials, physics and optics at the Harbin Institute of Technology, and the Shanghai Jiao Tang University, in China, showed the colloidal motion wave as a heterogeneous excitable system.
