摘要: Here we report a femtosecond anomaly observed at solid–liquid interface: acoustic echo being advanced by the application of viscous liquid to solid surface. Through extensive simulation and experiments, attribute this new discovery effect introduced surface-adsorbed water layer, switching between properties more than solid-like ice. Our study further indicates technology paradigm: system probe viscoelastic which is not achievable any available current technology.
