Abstract
Hydrogen fuels have been studied as a potential alternative energy source though the storage of hydrogen has not been an easy task. One answer to increase storage capacity is to introduce well dispersed metal nanoparticles onto the surface of the nanotubes to alter the surface chemistry of the nanotubes. It was shown that plain sonochemically treated nanotubes had an ambient (25°C) hydrogen uptake of 0.75%, while nanotubes doped with 5.3 nm diameter Pd particles gave an ambient uptake of 3.5%. Initially a broad range of pH between 4 and 10 was used to determine the effect, if any, of pH on the Pd deposition on the CNTs. Once an initial pH had been determined, a smaller range around a pH of 6 was used to narrow the results down to a more specific pH. For this study, a range between 5.3 and 7.3 was studied. Again, the general effects were seen as before, and an optimal value was determined to be 6.3.
Biography
Located on the west coast of India, Bombay is one of the biggest cities of the world with a population of about eighteen million. I come from this city of dreams, where I was born and brought up. My childish dreams were often of being a scientist, at other times an actor while there were still other times when all I wanted to be was a pilot and yet at others I wanted to be someone who could have it all. Well having grown up in to a mature and sensitive individual, I am surprised at how far-fetched my young aspirations were! For long now I have nurtured a dream to attain the power to 'Engineer' my life in a productive and progressive way. Studying properties of particles of minute sizes, as small as in the range on nanometers, has continually interested me in pursuing Chemical Engineering. It was this interest that forced me to come all the way on the other side of the world to get the best education and research work. Though it's been just a little more than six months in a completely new country, it still feels like a Jot of years. UMR has been a wonderful experience so far. Not only is UMR one of the finest Engineering schools, but also a great place to live. Within six months it has given my life directions to its destiny.
