Scientists were able to cool water drops to the temperature – 42,55 °C, keeping them in the liquid state. To obtain such supercooled water in the absence of her impurities, which act as centers of crystallization.

Until now, scientists were able to cool the water to a maximum of 41 °C, while microdroplets was absolutely clean and had no contact with a solid surface. However, an international team of physicists under the leadership of Robert Grisenti from the University of Frankfurt set a new record.

To obtain the supercooled liquid drops and accurately determine their temperature, the authors used the method of fast evaporation in vacuum in combination with Raman.

This approach allowed to cool drops, first to about 6.3 microns, to a temperature – 42,55 °C. Even with an error of 0.5 degrees the result of more than one degree higher than the previous record.

As noted by the authors, these results will be useful in the study of the crystallization of ice in the atmosphere and constructing reliable climate models.
