- Nanoparticles :
Our group has been working on the preparation of nanoparticles of
metals, metal salts, metal oxides and semiconductor nanoparticles using
water-in-oil microemulsions. We have been studying some of the
important scientific and engineering issues both experimentally and
theoretically. We are also currently studying the formation of
nanoclusters from precursor solutions.
- Liquid Nanocomposites :
Our group has been working to develop superhydrophobic surface coatings
based on both chemical and physical modifications on the surface.
- Foams :
Our group in the past has done some amount of work on liquid foams
addressing both generation and stability issues. Currently we are
working on the technology and modeling of metal foams.
- Contaminants Transport in Porous Media :
Our group has been working to study the influence of the presence of
indigenous colloids on the contaminants transport in porous media. Both
facilitation and retardation effects on the transport of contaminants
have been observed.
