Abstract
Carbon nanotubes (CNTs) are cylindrical carbon tubes of nano-structures (10-9 nm) with properties that make them attractive for use in various applications.  Carbon nanotubes can conduct heat and they have amazing strength as well as potential to be exceptional electrical conductors.  Carbon nanotubes have great promise for use in mechanical, electrical and biomedical fields.  For example, carbon nanotubes can be used in reinforcement for multi-functional materials used in conductive plastics for electromagnetic shielding, storage media for hydrogen fuel cells, or nano-based advanced drug delivery systems.  The goal of this research project was to study the effects of reduced-gravity on the electrodeposition of atomic metallized nanostructures on the surface of CNTs.  This research hypothesized that the unique molecular character of the reduced-gravity metallized carbon nanotubes (rgm-CNTs) and normal-gravity metalized carbon nanotubes (1gm-CNT) could be distinguished by Raman analysis, and thus providing a spectrometric means to molecularly characterize and optimize the synthesis metallized CNT.  Consequently, this project systematically explored and compared Raman spectroscopic analyses of metalized nanostructures electrochemically deposited onto CNT surfaces both in reduced-gravity and normal-gravity conditions.
