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.

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.

Suspensions of Polymer Coated Colloids

This is an experimental project that would involve synthesis of colloidal particles followed by grafting of polymers. Self-Assembly and rheology for suspensions of anisotropically grafted partciles will be studied.

Interested students may contact me for further information.

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.

Functional Nanoparticles: Experiments, modeling, simulation (TA/FA)

Nanoparticles and their clusters show new and interesting properties different from bulk
materials due to their extremely small size (diameter) and large specific
surface area. It is thus critical to understand the variables that control
its formation leading to a desired property. Control of nanoparticle size,
size distribution and particle-cluster formation is the first step in all these applications. To gain
further insight into the mechanism of formation of nanoparticles and its clusters, we will  read more »

A Method and an Apparatus for Synthesizing Vesicles by Interdiffusion of Stationary Phases

The present invention relates to a method and an apparatus for synthesizing stable uni-lamellar vesicles (liposomes) for drug delivery and similar applications. The main advantage over existing methods is the ability to produce in a single step, stable liposomes of a mono-disperse population in the size range of 200-5000nm controlled by temperature and lipid type alone, without subjecting to harsh environments and with negligible external energy supplied. The method of the present invention is simple, feasible and inexpensive for the large-scale production of liposomes.
