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 »

Flow Assurance of Waxy Crudes in Pipelines

Crystallisation and subsequent deposition of waxes in pipelines transporting crude oil, water is a long standing concern in the petroleum industry. Waxes may nucleate and grow at the pipe walls or may be transported while growing in the bulk. Propensity of the waxes to block the pipe cross-section depends on whether the crystals are in close enough proximity to touch, and perhaps, bond with the other crystals so that a space-spanning network, like that in a truss, can be formed.  read more »

Design of nanoporous materials for gas separation (TA or FA only)

Natural gas meets around 20-25% of world energy demands. Overall the world has around 200 trillion cubic meters of natural gas reserve and new reservoirs are being found. Methane gas constitutes around 80-90% of natural gas and for economical utilization of methane as fuel, efficient separation technology is required. The aim of this project is to design new nanoporous materials for methane separation and storage from natural gas.

Materials for water purification and desalination (TA or FA only)

Although earth is covered with 70% of water, only 2% of it is available as fresh drinkable water. Access to this fresh water is scarce in many parts of the country. The groundwater contamination due to industrial pollution and geological minerals leads to many health issues, especially in childrens and women. Conversion of sea-water to fresh water is an expensive and energy-intensive process. The aim of this project is to find organic and inorganic porous materials for water purification.

Mechanisms of failure in lithium ion battery

Lithium ion batteries are used with a number of electronics gadgets.
Extending their application to high power applications is a major
research problem due to the rapid loss in capacity in these batteries. The goal is to investigate mechanisms that lead to the detoriation in
battery performance primarily using computer simulations and comparing
with experimental results obtained in our group.

Students are encouraged to approach Prof. Chatterjee for more information.

Functional Nanoparticles: Experiments, modeling, simulation (TA or FA topic)

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,  read more »

Sensing and removal of pollutants from water (TA or FA topic)

This research involves primarily experimental work to both detect environmental pollutants (by developing sensors) and remove them from water. This includes pollutants of different classes, like metals, organic dyes; and even contaminants, like bacteria etc. The aim is to both sense and remove the pollutants by use of nanoparticles and hybrid nanomaterials.  read more »

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.
