Energetic Considerations and Structural Characterization of Twinning in Nanowires
… in this dissertation is to study twinning in nanowires. Both gold and platinum <111> oriented nanowires were fabricated by similar solution-phase chemical synthesis methods. High-resolution transmission electron microscopy and electron diffraction patterns were carried out to analyze the …

Nanomaterials Self-Assembly Driven by Beta-Amyloid Peptides
Nanomaterials such as gold nanowires and gold nanoparticles were self-assembled with several peptides derived from betaamyloid peptide. The peptides propensity to form fibrilar structures was exploited. The products obtained by aggregation of the peptides with the nano materials were studied using …

Fabrication, assembly, and electrical characterisation of gold nanowire
… synthesis, manipulation and characterisation of gold nanowires. Porous alumina membranes have been electrochemically fabricated as templates for the deposition of gold nanowires. They consist of a thick oxide membrane, shown to be perforated by a high density array of isolated cylindrical pores, …
