Today is UN World Water Day – a day for water and for sustainable development.
This year, World Water Day focuses on the following ideas: water is health; water is nature; water is urbanisation; water is industry; water is energy; water is food; and water is equality. But I want to add something to this list: water is chemical engineering.
The importance of water is often overlooked. Water is not only essential for life but it is of key importance in chemical engineering too.
In the past, I have discussed the relationship between water and food, water and energy and the water-energy-food nexus, and I can’t stress enough the importance of these interdependencies.
Today, however, I thought I’d focus on the more light-hearted work of the chemical engineers at the University of Minnesota, US, who are working to understand the impact of raindrops.
