Our work on metamaterial perfect absorbers at mid-infra-red have been reported in
i. Journal of Optics (IoP, UK), 16, Art. No. 094016 (2014) doi:10.1088/2040-8978/16/9/094016

These works demonstrate new methods of fabrication of mid-IR metamaterials as well as perfect absorption that arises from multipole excitations of the metamaterial structures for the higher frequency bands. The second paper explores the use of Indium tin oxide instead of metals for making mid-IR metamaterials. The fabrication methods are highly suitable for rapid mass production of metamaterials.

Our work on evaporation of sessile droplets on nanoporous alumina has been published in the journal, Colloids and Interfaces A: Physicochemical and Engineering Aspects 432, pp. 71–81 (2013);
DOI: dx.doi.org/10.1016/j.colsurfa.2013.04.070,
It has been shown that the evaporation of droplets on nanoporous surfaces can be much faster than on plain surfaces and the rate of evaporation depends strongly on the nature of ordering on the nanopores on the surface. Nanoporous alumina surfaces were prepared with three different surface morphologies by anodization methods. Penetration of the fluid into the nanopores and formation of air bubbles has also been shown. These results are of immense potential for evaporative cooling applications.
