Development of Superparamagnetic Iron Oxide Core-shell Nanoparticles and Its Applications in Modern Drug Delivery Systems
The focus of my present research project is the functionalization and tailoring of nanoparticle surfaces to perform specific tasks in a biological environment. The particles include superparamagnetic iron oxide nanoparticles, core-shell nanostructures and superparamagnetic iron oxide nanocomposites. The unique nanomaterials have been developed to address continued issues in cancer therapy, including cancer diagnosis and efficient drug delivery.

My research is focused on the electrochemistry of nanostructures, anodization methods, sputtering techniques and various characterization tools. My current project is based on the spectroelectrochemistry of titanium dioxide nanotubes loaded with copper. The motivation behind this project is to develop a cost effective and more efficient photocatalyst that can be used to kill harmful pollutants from water. Previously, I was working on the investigation of the titanium oxidation mechanism using cyclic voltammetry. I have also worked on controlling the degradation of magnesium alloys using surface treatment like anodization, plasma arc oxidation and various coating techniques. Furthermore, one of my project was based on the effect of visible light on the water splitting capability of titanium dioxide nanostructures.

Graphene/SPION-photocatalytic nanocomposites as nanosorbents for the water and wastewater treatment.
I am currently working on the photocatalytic nanocomposites for water and waste water treatment.
This project is based upon the development of nanocomposite of graphene oxide with core-shell Fe3O4/ZnO/TiO2
nanoparticles as nanosorbents for the removal of toxic ions and bacteria from water and waste water. The nanostructure composite developed for this purpose will consist of a mixture of functionalized graphene oxide and core-shell nanoparticles of Fe2O3/ZnO/TiO2.
In the past years it has been shown that graphene has a very high electrical conductivity of electron knows as ballistic behavior. Combination of this character with being hydrophilic in nature, will provide higher efficiency of the water purification process. The Fe3O4, TiO2 and ZnO photocatalysts act as nanosorbents in UV-vis light and attract all the micro level impurities such as metal ions (e.g. Pb+2 and Cr+6) and dissolved minerals with chloride and sulfate ions. This nanocomposite is expected to be an excellent contribution in the field of water purification and separation.

Potential of Graphene and Related Materials in Biomedical and Energy Applications
It comprises of two parts; biomedical and energy. I have successfully completed the first half of my thesis in which I coated functionalized graphene on titanium alloys to study the corrosion behavior and cyto-compatibility of alloys.
My current focus is on studying graphene and its derivatives as potential candidates for hydrogen storage materials. The project involving energy studies would cover both theoretical and experimental aspects. I have done the literature review for the existing theoretical studies about hydrogen adsorption on carbon materials and calculating the experimental values for adsorbed hydrogen using electrochemical techniques such as electrochemical impedance spectroscopy, galvano-static charge and
|discharge technique, linear sweep voltammetry and cyclic voltammetry. The next step in my project is to theoretically calculate the potential of hydrogen storage on doped graphene (doped with metallic ions i.e., copper, nickel etc.) using ab initio methods, mainly DFT. After obtaining the theoretical data, my plan is to perform experiments on doped graphene. Experimental validation for doped electrodes will be done using the same electrochemical techniques as mentioned above.|

Combinatorial development of bulk metallic glasses with potential applications for next-generation intracoronary drug-eluting stentsThe focus of this project is to fabricate a quintessential novel biomaterial for new-generation intracoronary drug-eluting stents. Amorphous multicomponent thin films will be developed using RF/DC Magnetron co-sputtering. Compositional libraries will be synthesized through the variation of sputtering parameters and
each composition will be extensively characterized to choose a system having incredible combination of biocorrosion resistance, biocompatibility, polymer-like formability and other mechanical properties desired for bioimplants. The chosen system will be both nanoimprinted and dealloyed via selective leaching for drug delivery purposes. Using a model drug, the drug-release-kinetics will be optimized via channelling the multiscale nanopatterns and induced nanoporosity.

Study of Effect of Surface Treatment on Mechanical Properties and Degradation Rate of Magnesium Alloy Stents-An FEA Approach to simulate Experimental Effects
Magnesium Alloys found appreciation in the field of Biomaterials because of their ability of Biodegradation. The biodegradability of Magnesium Alloy Implants significantly reduces the surgical procedure. The only problem associated with the Magnesium Alloy Implants is the short degradation time providing insufficient scaffolding. In this study I am work on the magnesium alloy stent and investigating its performance on the basis of mechanical properties and degradation time. My project focuses on the surface treatment of magnesium alloys by anodization. Based on experimental results a surface treated magnesium alloy as our stent material is selected. Stent model was designed in SolidWorks 3D CAD Software. The stent is simulated in ANSYS for the mechanical behavior and degradation study. The purpose of this study is to investigate the mechanical response and effect on degradation time of stent by using the surface treated magnesium as stent material.

Microstructural and Electrochemical Investigation of 3-D printed Stainless steel
I am currently working on the investigation of electrochemical and microstructural behavior of 3-D printed stainless steel. This project aims to investigate the electrochemical behavior of 3-D printed stainless steel as there is no literature available on this topic yet, As 3-D printing of metals is a recent trend in the modern world due to the fact of cost reduction, less energy consumption, design effective and mass production associated to it. This project is based on the electrochemical study of 3-D printed stainless steel in different electrolytes based on varying pH level and different concentration of Chloride ions in De-Ionized water. This electrochemical data of 3-D printed stainless steel will help to formulate an iso-Corrosion diagram for this system.

The Effect of Voltage on the Diameter and Biocompatibility of Titanium Dioxide Nanotubes
Surface modification of alloy implants is a necessity to increase the durability and biocompatibility of orthopedic implants. Nanotubes are a development noted for their durability and strength, whose physical properties can be modified by differences in voltages and anodization times. It's hypothesized that by increasing the voltage during a 90 minute anodization time that the diameter of the nanotubes will increase, but the biocompatibility of these nanotubes must be examined to improve bodily acceptance of the implant with fewer adverse reactions. By examining cellular proliferation, apoptosis, and adhesion of pre-osteoblast cells the bodily acceptance of these implants with nanotube surface modification can be predicted and compared to current models used in orthopedics.
