Modeling on Mobility of Nanoparticles (Carbon Nanotubes) through Subsurface.

Nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic or molecular structures. Nanoparticles are sized between 1 and 100 nanometers, which may or may not exhibit size-related properties that differ significantly from those observed in fine particles or bulk materials. Carbon based nanoparticles are being developed for a wide variety of commercial applications including biomedical technologies, cosmetics and electronics. With increased production and use, it is inevitable that nanoparticles will reach subsurface aquifers (e.g., due to release of industrial wastewaters, accidental spills or landfill leakage). The production and use of nanoparticles will inevitably lead to their disposal in the natural environment. The limited toxicity work completed to date has been inconclusive. Nanoparticle characterization is necessary to establish understanding and control of nanoparticle synthesis and applications. In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. To assess the risk that these materials pose to human and ecosystem health an understanding of their mobility and ultimate fate is essential. The goal of my research is modelling the transport of nanoparticles specifically carbon nanotubes under the subsurface porous media.

Personal Background

S. N. Siddique graduated from Bangladesh University of Engineering and Technology (BUET) in October 2009. She completed the undergraduate Civil Engineering program and earned a Bachelor of Engineering Science. In her 4-year undergraduate program, she gathered knowledge in different basic divisions (Environment, Geo-technology, Structure, and Transport) of Civil Engineering. In the final year of her undergrad study, she chose Environmental Engineering as her major subject, and did her thesis on it. From a very early age, she participated in different scientific competitions, workshops, and conferences, which eventually made her interested to study in the Engineering field. After graduating, she applied to Western for M.E.Sc. program and subsequently started in May 2010. She is very fortunate that she got this opportunity at The University of Western Ontario. The RESTORE group at Western is quite a perfect place for her to do her research work. She hopes that with her determination, hard work, perseverance and dedication, she can successfully contribute to environmentally responsible projects.
