Title: Theoretical and experimental studies on textured surfaces for reduction of drag and inhibition of bacterial adhesion in microfluidic and biomedical devices.
Affiliation: Indian Institute of Technology Delhi (New Delhi), INDIA
Abstract: Micropatterned surfaces are desirable for their de-wetting, anti-bacterial, friction-reducing and flow anisotropy generating properties in various applications such as biomedical devices and microfluidics. In the current work, a combined theoretical and experimental study directed to the aspects mentioned above of micro-patterned surfaces. Microfluidic flows confined by surfaces with periodic slip patterns of arbitrary amplitude and pitch and separated by an arbitrarily specifiable gap are analyzed with a spectrally accurate mesh-free semi-analytical method. Experimental realization of super-hydrophobic surfaces was achieved by using a nano-second pulsed laser. Laser patterning was done on the bio-materials such as titanium alloy (Ti6Al4V). The pressure-discharge characteristics of the micro channels confirm friction reduction and also demonstrate a reasonable agreement with the theoretical predictions from the developed fluid dynamic model. A biomedical study of the laser patterned surfaces was also carried out to understand bacterial adhesion on these surfaces. Laser patterning on Ti6Al4V surfaces induced several oxides of Ti, V, and Al, which aided in de-wetting as well as in decreasing the surface potential (as confirmed by Kelvin probe force microscopy), thereby effectively reducing bacterial adhesion. The proof-of-concept was tested against gram positive Staphylococcus aureus and gram negative Pseudomonas aeruginosa. Hence, laser texturing is a promising technique for surface modification of surgical tools and implant surfaces.

Title: Optimization of Laser Machining Process for Preparation of Photo-masks and its application to Micro-systems Fabrication.
Affiliation: Indian Institute of Technology Kanpur (U.P.), INDIA
Abstract: The project involved design, simulation, experiments, and micro-fabrication of MEMS devices. Designing of photo-mask and device was done in AutoCAD and CorelDraw, followed by simulation in COMSOL. Experiments were designed and optimized with Design Expert software. Many experiments were done on the CO2 and Excimer laser machine to fabricate photo mask for photolithography. A MATLAB code was written for image processing to analyze the test and result both. CO2 and Excimer laser machining parameters were optimised. Various micro-features on a silicon wafer such as micro pillars, micro channels, micro electrodes, etc. of 5-10 micron size with 5 micron resolution were fabricated. At last, we did the characterization of various features by using MATLAB code and SEM analysis.
Bachelor of Engineering
Electricity Generation from Speed Breaker (B.E. Major)
The project involved a design of the product to utilize the waste energy. Energy losses in the environment due to friction were a target in this study. A slider-crank mechanism was used to convert the reciprocating motion of speed breaker into rotary motion of generator. We successfully tested the working model.
Study and comparison of biodiesel with conventional fuel (B.E. Minor)
The study involved comparison of biodiesel with regular fuel. It includes experiments with both fuels to evaluate and compare the performance. We had used “Jatropha seeds” to extract the oil and blend it with diesel, and tested it.
