Thermodynamic study of polymer-grafted nanoparticle composites.

Grafting polymer to the surface of nanoparticles can result in enormous property enhancements.  This project involves the study of thermodynamic properties of such composite systems.  The topic lies in the area of polymer physics.  The work involved, is the usage of simple statistical mechanical arguments and simulation packages to confirm the statistical mechanical predictions.  An introductory level exposure to programming should suffice.

Study of the structure and phase behavior of polymer-linked nanoparticles

Polymer-linked nanoparticles give rise to interesting ordered structures without the temperature playing any role.  The structures that are formed are purely entropy driven.  This project will involve the generalization of this behavior to determine the underlying reasons for the ordering through a series of mathematical simplifications.  We will also study what new kinds of phase behavior can be observed when the temperature begins to play a role.

Understanding Weathering of Roads

Formation of pot-holes on roads is a very common site in India during the monsoon. The applied asphalt layer on rocks (construction aggregates) de-laminates due to intercalation of water.The project is aimed at understanding this de-lamination process using simulations and experiments.

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.

Elasticity Relationships for Filled Elastomers

Filled elastomers or filled rubbers have found
extensive uses in industry. The fillers provide advantageous properties over
unfilled systems, leading to various applications. One important property that
bears investigation is the stress-strain relationship of the elastomers and its
relationship to the primary molecular architecture. Experimental data and
theoretical developments have been presented earlier. The current investigation
aims toward a systematic study of the objective relationship between molecular  read more »

Design of Materials using Arrested Microemulsions

The project will explore design of materials using nanostructured glasses. Presently our lab is preparing and charactertising these glass-like materials. An incoming student can take the project towards design of structured nanocomposites.  Experimentation will be based on tools required to characterize the rheology, microstructure and the phase diagrams. Interested students can approach me and also talk to the DD student presently working with these materials.
