Nanoscale materials are considered to be attractive building blocks for constructing novel devices due to their unique size-dependent, and often tunable, thermal, optical, electronic and magnetic properties arising from quantum confinement effects. In particular, there has been a great deal of interest in creating ordered assemblies of nanoclusters of select sizes, arranged in specific configurations. Scientists at NCL prepare several such hybrid materials in the form of nanotubes, and nano-composites inorder to reap their benefits in potential applications such as sensors, catalysis, nonlinear optics and single electron devices.
