Crystallization induced structure development in polymer nanocomposites

In polymer nanocomposites, inorganic nanoparticles are
dispersed in a polymer matrix to prepare materials with superior engineering
properties. Of particular interest are a novel class of materials, called
polymer grafted nanoparticles. These are nanoparticles that comprise an
inorganic core covalently tethered to a shell of polymer chains. Dispersion of
polymer grafted nanoparticles in a polymeric matrix is facilitated by favourable
interactions between the grafted shell and the matrix. In particular, when the  read more »

Simulaition study of Enhance Oil Recovery

In the secondary and tertiary phase of oil recovery, the crude oil in direct contact with mineral surface needs to be displaced using external medium, mostly water. The mechanism of replacement is governed by the structural and energetic behaviour of interfacial water versus hydrocarbon oil at the mineral surface. This project is aimed at understanding the interfacial behaviour of crude oil-water at mineral interface. The obtained understanding will be used to enhance the oil recovery.

Structure and Dynamics of Interfacial Water

Water is one of the most abundant, ubiquitous and essential material to sustain all biological life on earth. Most of the water exists in large bodies (bulk quantities) in the ocean, river and lakes. However, in many industrial and scientifically relevant conditions, water is associated with other surfaces. Understanding its structure and dynamics at molecular length-scale is useful in catalysis,corrosion, adsorption and atmospheric sciences.

Understanding the Shear-thickening phenomenon

Shear-thickening refers to the phenomenon where the viscosity of the liquid increases with shear. A familiar example is that of corn-starch in water, wherein the liquid can thicken to such an extent that it can even support the weight of person. While shear-thickening has been observed in some fluids and can lead to serious processing difficulties, the exact mechanism responsible for the thickening is not clear. The proposed project will investigate the role of interparticle forces and hydrodynamic interactions to understand this phenomenon.  read more »

Use of Arrested Micro-emulsions for Drug Delivery and Gas Separation Applications.

The project will explore design of materials using nanostructured glasses for which a patent has been filed. An incoming student can take the project towards design of structured nanocomposites for specific applications including membrane for gas separation and controlled drug delivery. Other experiments will be based on tools required to characterize the rheology, microstructure and the phase diagrams of these materials and design of materials.
