Apparently there is a lot more to boiling water than one might think. Researchers from the National Institute of Standards and Technology (NSTI) and Cornell University have uncovered the traces of ephemeral “nanobubbles” formed in boiling water on a microheater. A unique ultrafast laser strobe microscopy technique was used to observe the process with an effective shutter speed of eight nanoseconds to photograph bubbles growing on a microheater surface about 15 micrometers wide.
These experiments are believed to be the first evidence that nanoscale bubbles can form on hydophilic surfaces and could have immediate implications for inkjet printing and even thermal cancer therapies.
My cup of tea will never look quite the same from now on - and no wonder I feel great after a cup if it contains all these nanobubbles!
