The physicochemical nature of colloidal motion waves among silver colloids
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 ...
Axisymmetric 'spike waves' far exceed limits previously thought to dictate maximum height of ocean waves
In a new study on ocean wave breaking, researchers have demonstrated that the breaking behavior of axisymmetric "spike waves" is quite different to the long-established theories on the breaking of traveling waves.
