The phase behavior of connected hard and soft particles.

A surprising new development in materials science and chemical engineering is the finding that mixtures of hard (colloidal), and soft (polymeric, or micellar) particles can self organize in length scale much larger than the diameter of either species.  In this project we explore the behavior of connected hard- and soft particles.  An elementary knowledge of coding is sufficient.

The role of impurities in the self-assembly of polymer-grafted nanoparticles.

Traditionally, self-assembled structures are formed using chemical differences within a species.  Examples of this are the formation of micelles by detergents, and the formation of the phospholipid bilayer of the cell membrane.  In these systems, it is the tendency to the hydrophobic and hydrophilic part to avoid each other that result in the  self-assembled state.  However, a recent study (http://pubs.rsc.org/en/content/articlehtml/2017/sm/c7sm00230k) has pointed out that it is possible to form self-assembled states without any chemical differences.  This project focuses on how the prese  read more »

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 »
