Film formation and anti-microbial studies of nano-composite coatings (Joint supervision with Prof. Mahesh Tirumkudulu)

Preventing or
inhibiting the growth of micro-organisms on surfaces is of prime importance in
the healthcare and textile industries. A promising strategy to overcome
microbial growth involves coating the surfaces with materials that can provide
resistance to microbial colonization. Inorganic nano materials and organic
materials with inorganic inclusions are being widely used as anti-microbial  read more »

Atomization: Break-up of thin liquid sheets

The process of atomization, which involves the break-up of a mass of liquid into tiny droplets, plays an important role in many industrial applications such as spray combustion, spray painting, agricultural sprays, ink jet printing, and powdered milk processing to name a few. One of the main objectives of the atomization process is to control the drop size distribution so as to achieve the desired process efficiently.  read more »

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.

Structure and Dynamics of Interfacial Water

Water is one of the most abundant, ubiquitous and essential material to sustain all biological life on earth. Most of the water exists in large bodies (bulk quantities) in the ocean, river and lakes. However, in many industrial and scientifically relevant conditions, water is associated with other surfaces. Understanding its structure and dynamics at molecular length-scale is useful in catalysis,corrosion, adsorption and atmospheric sciences.

Design and synthesis studies of porous materials

Please contact me if you are interested in this area. The project is
compulational base and would involve lots of programming and running
simulation softwares. The skills required are; a) good basics in
transport phenomena, b) basic (primariy level of) understanding in
interfacial science and c) good programming skills.

Small Angle x-ray scattering system

saxs.jpg

This instrument uses the principle of elastic scattering of X-rays (wavelength 0.1- 0.2 nm) by a sample which has inhomogeneities in the nm-range.This scattering is recorded at very low angles between 0.1 to 10 degrees. This angular range contains information about shape, size, intemolecular distance, porosity etc. It incorporates an imaging plate detection system that provides a 2-dimensional scattering pattern with a wide linear dynamic range. A non-ambient sample holder allows for measurements at temperatures from -30 to 120 °C or from room temperature up to 300 °C.  read more »
