Random Walk

This project was done under the guidance of Prof.Abhishek Dhar from Raman Research Institute (Through Indian Academy of Science) during summer of 2010. The project was intended to be a reading work on random walk and brownian motion. Later on at the end I was also able to work on random walk with memory were the probability of the steps taken(Forward or backward) changed depending on the previous step taken. It was told by him that works were done in this area to find systems which mimic the motion of bacteria especially amoeba.

Optical and Electronic properties of Ti1-xNbx thin filims

This work was done under Prof. Ghanasyam Krishna at Thin films lab from the university were I did my Masters (University of Hyderabad). We studied the optical properties of Titanium Niobium Nitrate using the Classical Lorenz Drude model of the atom. Using the fitted data of the reflectance of the material the band gaps were determined and how they change with varying concentration of Ti and Nb. The results of this work was published in an international journal and a conference.

Optical reflectance, dielectric functions and phonon-vibrational modes of reactively sputtered Nb-substituted TiN thin films

Study of absorption of grated structures

This was done as part of my final semester project to full fill my I.M.Sc degree.The aim of this project was to study, understand and replicate the research work done by Zongfu Yu and Prof. Shanhui Fan on the fundamental limits of light trapping by grated structures.

Droplet generation for microfluidic devices

This project was done under the super vision of Dr Jeron Van Kan Atton and research assistant Tan Huie Ming at National University of Singapore. Micro-Fluidics is a new area of research interest , were flow of fluids are controlled by passing them through channels of micron dimension. Because of the micron dimension the flow of the fluids will be laminar inside the micro channels. This gives good control over the flow of the liquid. I fabricated a T - Junction using photo lithography and generated droplets of different fluids with it.
