Several lithography technique are being covering all length scales from photo litho, NSOM, e-beam and FIB are being pursued. These are being augmented by novel techniques being developed at IITK based on self-organisation and self assembly. These include entirely new techniques developed at IITK such as Elastic Contact Lithography, Adhesion Assisted Lithography and e-field lithography.
Super hydroscopic surfaces are being tailored by the growth of nano-porous silica films at oil-water interfaces and other polymers are being made super-hydrophobic by meso-texturing.
AFM measurements of force of particle adhesion are being carried out
Nanoparticles of CoPt (ordered fct and disordered fcc phases) are being prepared using strained epitaxial growth on (001) STO and (001) MgO substrates. One of the objectives is to realize the suitable conditions of strain for the Stranski – Krastanov type growth.
A novel liquid phase pulsed laser ablation technique is being developed to synthesize nano particles of a variety of metals, alloy and multicomponent oxides. The technique involves the use of pulsed Nd-YAG laser operated at the fundamental and first harmonic frequencies.
Theoretical and computational approaches based on meso mechnics of materials are being pursued, including nano-crack formation in adhesion.
Polymes-silica and polymer-nanoclay nano-composites synthesis for enhanced mechanical, optical and barrier properties.
Novel fabrication techniques for Carbon MEMS, and fractal carbon structures are being developed with a view towards applications in carbon microbatteries and C-MEMs bio platforms.
Micro-nano hierarchal activated carbon structures impregnated with nano-catalyst particles are being developed for catalytic adsorption of pollutants and water/air purification.
