A huge number of the challenges we face surrounding water center on the interface between water and the materials that make up the systems that handle, process and treat water.
Gaining a deeper understanding of what takes place when water — and matter dissolved or suspended in water — comes into contact with those solids is the focus of the Argonne-led Advanced Materials for Energy-Water Systems (AMEWS) effort. For example, in many water systems, a phenomenon known as fouling — the accumulation of unwanted material on solid surfaces to the detriment of function — occurs at interfaces.
Other areas AMEWS is exploring are reactivity (chemical reactions) at interfaces and transport through porous materials.
