Structural And Thermodynamic Anaylsis Of Self-Assembled Dna Cross-Tiles, Lauren Hakker
Structural And Thermodynamic Anaylsis Of Self-Assembled Dna Cross-Tiles, Lauren Hakker
Legacy Theses & Dissertations (2009 - 2024)
A thermodynamic and structural analysis of DNA nanostructures was performed, following the replacement of the unpaired thymine bases within a central loop to determine their effect on the self-assembly process. Specifically this study focused on DNA cross-tile nanostructures. Self-assembly of DNA cross-tiles occurs by means of Watson-crick base-pairing interactions between designed single-stranded DNAs from which lattice structures assemble through sticky-end cohesion. These cross-tile structures were constructed from nine single-stranded DNAs and consisted of a central loop containing 16 unpaired thymine bases, four shell strands, and four arms. Modifications were introduced to replace the central unpaired thymine base loop. The modifications …
The Influence Of Copper Substrate Orientation On Graphene Growth, Zachary Robert Robinson
The Influence Of Copper Substrate Orientation On Graphene Growth, Zachary Robert Robinson
Legacy Theses & Dissertations (2009 - 2024)
This dissertation is focused on determining the influence of the copper substrate on graphene grown by \ac{CVD}. Graphene, which can be grown in single atomic layers on copper substrates, has potential applications in future electronic devices. One of the key issues for the use of graphene grown by chemical vapor deposition for device applications is the influence of defects on the transport properties of the graphene. For instance, growth on metal foil substrates results in multi-domain graphene growth because the foil substrates themselves have a variety of different surface terminations. Therefore, they don't serve as a very good template for …
