Pulak Dutta's research is focussed on nanoscale order in soft materials, particularly at surfaces and interfaces. A material is considered 'soft' if its structure and thus its properties are easily changed; interfaces cause molecules to arrange in new ways and thus help build potentially useful new materials. Dutta's research group seeks to understand what structures are formed under what conditions, and why. In particular, they do in-situ X-ray scattering studies on physisorbed (so-called Langmuir) and chemisorbed (so-called self-assembled) molecular monolayers and multilayers, and on interfacial liquids. Much of this research is done using synchrotron radiation at the Advanced Photon Source at Argonne National Laboratory, and at the National Synchrotron Light Source at Brookhaven National Laboratory.
