Topic 1: Functional Nanoparticles: Experiments, modeling, simulation

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 »

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.

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.

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.

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

Posted August 26th, 2011 by p.sunthar

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.

Model-Control Dynamic pH meter
Student In charge-Renu Kulkarni
-A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading.  read more »
