"Unveiling Negative Pressure through Light and Sound Waves"

Researchers at the Max Planck Institute for the Science of Light have developed a new method to measure negative pressure using liquid-filled optical fibers and sound waves. By encapsulating nanoliters of liquid in a closed optical fiber, the scientists were able to explore the unique thermodynamic states of the liquid. The combination of optical and acoustic waves allowed for precise pressure measurements and spatially resolved imaging inside the fiber. This new measurement technique provides insights into thermodynamic dependencies and opens up possibilities for monitoring chemical reactions in toxic liquids and investigating hard-to-access areas of thermodynamics.
