Ice in nature is surrounded by liquid most of the time, and therefore it is key to understand how ice and liquid interact. A Kobe University and Institute for Molecular Science study could now for the first time directly observe the precise shape of ice at the interface between ice and liquid -- by using antifreeze and a refrigerated microscope.
To get closer to understanding how ice interacts with its surrounding liquid, researchers led by Kobe University's ONISHI Hiroshi decided to try the next best thing. He says:"We came up with the idea of measuring ice immersed in antifreeze colder than 0°C. This way, the ice doesn't melt and the interface doesn't move, and it should be possible to make precise observations." Even so, the researchers struggled to get good measurements of the ice.
The researchers hope that their results will invite further study of the ice-liquid interface, but they have also set clear goals for their own future work saying:"We expect to increase the resolution of the microscope to single water molecules and use measurement methods other than atomic force microscopy. In this way, we hope to expand the range of possible applications of molecular-level measurements of the ice-antifreeze interface.
In 1842, the famous British researcher Michael Faraday made an amazing observation by chance: A thin layer of water forms on the surface of ice, even though it is well below zero degrees. So the ...
