Personal Statement Of Application For Nannomaterials

I am applying for the position of Research Associate to work with you and Professor Yves Chabal. I have applied to the position through the website of the University of Texas at Dallas as well. Fueled by the revolutionary changes brought by nanomaterials in today’s world, especially in dye-sensitized solar cells, I joined the Department of Chemistry to do research on nanotechnology while preparing to take a Master’s degree in Physics from the same university with a solid foundation in materials science, basic electronics, advanced device electronics, quantum physics, and computational physics. According to the International Energy Agency’s 2015 World Energy Outlook, a complete de-carbonization of the world’s energy system is needed for a†¦show more content†¦The following summaries of my research accomplishments, I believe, should be able to support my enthusiastic approach to bring a substantial change in the research progress in the department o f physics and materials science. I for the first time created a strong covalent amide bond between TiO2 mesoporous films and N719 by chemically modifying TiO2 with 3-aminopropyltrimethoxysilane. The dye-sensitized solar cells thus prepared were stable and more resistant to UV light, thermal stress, acid, and water when compared to traditional photoanodes. There was a dramatic preservation of the SCN ligand of N719 on the TiO2 surface for up to 6 months, which is not possible in the case of other modified photoanodes with dye attached non-covalently through electrostatic or hydrogen bonding interactions. (Langmuir, 2013, 29, 13582-13594). I extensively studied the synthesis of nanomaterials, quantum dots such as ZnS, CdS, electrodeposition of semiconductor oxide materials, preparation methods for different shapes (nanowires, nanotubes, and tree-like structures) and sizes (3-300 nm) of nanomaterials to accomplish this research work. I did research on molecular linkers to link quantum dots. In addition, I explored the charge injection dynamics from the excited dye (N719) to TiO2 semiconductor nanoparticles after chemical modification of the TiO2 nanoparticles with silane linkers using the ultrafast transient absorption
