Surface Composite by Friction Stir Processing:
Fabrication, Characterization and Particle Distribution Analysis of Al 1050-B4C Friction Stir Surface Composite
This study aims to fabricate and characterize Boron Carbide reinforced Aluminum matrix surface composite. The composites are fabricated with varying number of grooves and number of passes to analyze the change in reinforcement content and change in the distribution pattern of reinforcement particle. Microscopic analysis of the composites is accomplished using optical microscopy and scanning electron microscopy to show the formation of the defect-free surface composite. Hardness and tensile strength are measured to analyze the mechanical properties of the composite. Corrosion behavior of the surface composite is investigated by polarization curve and electrochemical impedance spectroscopy technique. The tribological properties of the composite are tested by performing reciprocating wear testing. (Publication in progress)
Bio-inspired Aluminum Composite reinforced with Soft polymer with enhanced strength and plasticity
There is a constant attempt in making low-density materials with better mechanical and corrosion resistance properties for applications at elevated temperatures. Normally hard particles are reinforced in the aluminum matrix, which leads to high strength and low ductility. Here, an attempt has been made to enhance both strength and toughness simultaneously by reinforcing a low-density polymer (PET, i.e., soft material) in the aluminum matrix using easily scalable and simple friction stir processing. Mechanical properties of the uniform reinforced composite show double ultimate strength and five-fold improvement in plasticity. The composite strength increases at elevated temperature compared to the base matrix. The experimental observations have been further supported by theoretical calculations and molecular dynamics.

Dissimilar Material Friction Stir Welding:
Atomically locked interfaces of metal (Aluminum) and Polymer (Polypropylene) using mechanical friction
Demonstrates that mechanical friction can be utilized to form atomically locked interface joints between two different materials (metal and polymer).
Atomically locked interfaces formed in such joining result in a waterproof and strong interface. The tensile and bend tests confirm the resistance to fracture due to the interlocking morphology, which exists at a macro level and extends to the atomic scale.
Fully atomistic molecular dynamics simulations to further gain insights on the joining process.

Design and Development of Step Climbing Wheelchair
Autonomy in the area of mobility is now accepted to be of high value. This is sometimes hampered due to some form of disability. Hence, wheelchairs continue to play a vital role to allow for mobility of the disabled people. But this autonomy is severely diminished in environments having steep slopes or staircase. Thus, a wheelchair having staircase climbing ability could be the remedy. Additionally, such a wheelchair could also provide an easy means of transport for patients in hospitals. An attempt has been made to design such a wheelchair that will provide increased mobility in environments with staircases and steep slopes. The aim of this project is to propose a mechanism for staircase climbing of wheelchair and to analyze the effectiveness of the same. The different mechanisms have been analyzed and compared to select the most suitable mechanism. The mechanism thus chosen has been modeled and analyzed using SOLID-WORKS. After making the necessary design, a prototype of the proposed wheelchair has been developed.

Capsule Characterization
This project was a course project for the subject "Characterization of Materials." The project demonstrates the ability to characterize the given unknown sample using an optimum (minimal) number of different characterization techniques available. A cost analysis of the project has also been evaluated.

These temperatures were used to model the thermal stresses induces and thereby measure the distortion. the distortion profile obtained closely matched to the experimental profilometer readings obtained
Shape Memory Alloys
Shape Memory Alloys (SMAs) are a class of shape memory materials (SMMs), having the ability to ‘memorise’ or retain their original shape when subject to stimulus. Stimulus can be thermo-mechanical or magnetic variations. SMAs are in high demand and are of significant research interest today due to a broad range of commercial applications, their unique and superior properties. The following article, in general, gives a context of the SMAs as well as their working mechanisms, applications, and the recent advancements in the field. The report aims to provide a generic overview and introduce the SMAs and describe the life cycle to date.
Superhydrophobic Materials
The term paper is a review of the hydrophobic materials. It will introduce the topics of hydrophilic and hydrophobic surfaces. The terms such as contact angle, surface energy which is related to these properties and other similar terms are explained. There are many hydrophobic materials present naturally which exhibit exciting features such as self- cleaning. Efforts are made to bio-mimic these structural on an artificial material to derive such properties and utilize them to produce anti-corrosion, anti-icing, anti-biofouling, anti- microbial surfaces. The paper illustrates the research at the University of Rochester to create the hydrophobic effect by femtosecond laser treatment. The results obtained by such a procedure are found to be promising and efficient in a large variety of applications.

Term Report on SIMS
Secondary ion mass spectrometry is a powerful imaging technique which is widely used in both industry and academia to determine the composition of a material in localized microscopic regions within the surface or near the surface region. SIMS although is an destructive technique by principle, it is a very efficient method of analysing the surfaces. By the use of various modes of SIMS , one can obtain wide variety of data from the surfaces. This technique is the solid state version of mass spectrometry where the samples are primarily in the liquid state in the former.
The use of fossil fuels is now widely accepted as unsustainable due to depleting resources and the accumulation of greenhouse gases in the environment that has already exceeded the “dangerously high.” Fuel production process are required which are not only renewable but also sequester atmospheric CO2 to achieve environmental and economic sustainability, Currently, nearly all renewable energy sources target the electricity market, while fuels make up a much larger share of the global energy demand.. Microalgae are a diverse group of photosynthetic microorganisms that proliferate due to their simple structure. Can they potentially be employed for the production of biofuels in an economically productive and environmentally sustainable manner?
