A study by a team of physicists and biomedical researchers at Aalto University has discovered a new class of waves that travel at extraordinary speeds on water-repellent surfaces, opening up new perspectives for monitoring thin gas layers. The discovery could transform biotechnology, materials science and improve the efficiency of industrial processes.
Capillary waves, which are produced when droplets fall onto a surface, are a well-known phenomenon. They have been studied for centuries because they provide important information about the properties of a surface. However, the latest research has focused on the novel properties of capillary waves that form on superhydrophobic surfaces—materials that repel water. These surfaces are able to retain a thin layer of gas, known as a plastron, underwater, which acts as a barrier against corrosion and contamination, and also improves hydrodynamic properties.
A particularly important aspect of this research is the discovery of new “plastron waves” that travel 45 times faster than traditional capillary waves. This achievement not only sets a new speed record, but also allows for better monitoring of plastron stability, which is key to the effectiveness of superhydrophobic surfaces. The application of this technique allows for more accurate data on the stability of the gas layer, which could help improve the durability of equipment and increase the efficiency of industrial and biomedical processes.
It is predicted that the new technologies could have a wide range of applications, particularly in biotechnology, where they could help measure changes in plastron stability, which would allow for improved monitoring in pharmacology and cell technology. Using waves to study this thin gas layer opens up new possibilities for improving sensor systems and expanding research in various scientific and industrial fields.
