This year's theme is water cooperation, for peace and security in its broadest sense. World Water Week will take place in Stockholm on August 24-25, 2024, when the winner of the Stockholm Water Prize will be announced.

Water research at Fysikum

The Division of Chemical Physics hosts the research group XSOLAS, which stands for Experimental X-ray studies of liquids and surfaces (XSoLaS). The group focuses on the structure, dynamics and physical properties of water and water solutions.

One of the research projects is Water, Ice and Water Solutions.

- It has been known for several decades that many of the properties of water, such as density, compressibility and heat capacity, become strongly deviated when the temperature drops. This deviation from simple fluid behavior is particularly strong when water is cooled below the freezing point to the metastable supercooled regime", says Professor Anders Nilsson, Fysikum.

Lars G.M. Pettersson, Professor of Theoretical Chemical Physics at Fysikum was awarded a 2021 Advanced Grant from the ERC for the project "Gases in Water".

- There is now growing evidence that there are two forms of liquid water: a high density liquid (HDL) and a low density liquid (LDL). The researchers will develop an improved theoretical description of how water molecules interact through computer simulations of the fluids," says Professor Lars G.M. Pettersson.
