RSC Prizes and Awards Lecture hosted by Dr Dwaipayan Chakrabarti

In this talk I shall report several research findings from my group over the past years, including: (1) New phases of low-dimensional nano-ice and ice clathrate; (2) superhydrophobic phenomena at the nanoscale, e.g. Lotus effect at nanoscale; and (3) growth pattern of small-sized gold clusters.

Understanding physical and chemical properties of confined water at nanoscale has implications to diverse phenomena at the intersection between chemistry, biophysics, and mechanical engineering, such as the design of nanofluidic devices and synthesis of antifreeze proteins for ice-growth inhibition. Low-dimensional water/ice exhibits many fascinating phase behaviors that have not been seen in bulk water/ice. Gas hydrates are solid-state materials typically consisting of a host ice-frame with nanoscale cages that serve to trap small guest molecules such as methane. Methane hydrate is one of the most significant energy sources. Like low-dimensional ices, low-dimensional gas hydrates also show distinct features not seen in bulk gas hydrates. Bulk gold is known to be catalytically inert, whereas gold nanoclusters can exhibit exceptional catalytic properties towards CO oxidation. We have performed a comprehensive study of structure-function relationship for the sub-nanometer gold clusters, hollow golden cages in particular.
