Water-Like Properties of Soft Nanoparticle Suspensions

November 25, 2013

Certain unusual properties of water have intrigued researchers for decades, but are hard to investigate owing to inherently small length scales and complex interactions. Now researchers using the Advanced Photon Source at Argonne have achieved the first experimental observation of the arrangements and mobility of soft nanoparticles in dense suspensions that mirror the anomalies observed in complex liquids like water in a colloidal suspension. This finding extends the toolbox of researchers interested in using suspensions to mimic molecular liquids.
