Fall 2014
Rosette Nanotubes (RNTs) are a class of self-assembled organic nanomaterials generated through the spontaneous hierarchical organization of guanine-cytosine (G˄C) bases with a built-in self-assembling ability. Driven by non-covalent intermolecular forces in solution, G˄C bases self-assemble into...

(RADA)4 Self-Assembling Peptide based Hydrogels: Design, Characterization and In-Vitro Biological Evaluation
DownloadFall 2016
Ionic self-assembling peptides have emerged as promising nano-biomaterials, with direct applications in the fields of bioengineering and applicative medicine. (RADA)4 is a self-assembling 16 residue containing peptide, with alternating hydrophobic and hydrophilic residues. This characteristic...

Aquatic nanotoxicity testing: Insights at the biochemical, cellular, and whole animal levels
DownloadFall 2013
Aquatic organisms are susceptible to waterborne nanoparticles and there is only limited understanding of the mechanisms by which these emerging contaminants affect biological processes. The unique properties of nanomaterials necessitate evaluation of standard toxicity testing techniques to...

Spring 2014
The impressive developments in the semiconductor industry over the past five decades have largely been dependent on the ability to continually reduce the dimensions of devices on a chip. However, as critical dimension requirements for these devices approach the limits of photolithography, new...

Fall 2010
This thesis describes the fabrication and characterization of integrated hollow Bragg waveguides fabricated by controlled thin film buckling. Hollow waveguides based on two different set of materials were studied. In the first case, thermal tuning of air-core dimensions was studied using...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Molecular self-assembly is the basis of structure in Nature. While of far less complexity than a natural system, the same physical rules apply to simple synthetic designed systems that spontaneously form self-assembled structures and patterns. The self-assembly of block copolymers (BCPs) is an...

Fall 2015
Dangling Bonds (DBs) on the silicon surface exist when a silicon atom lacks a bonding partner, resulting in a localized orbital which is not involved in any chemical bonds. On the hydrogen-terminated Si(100) surface, such DBs introduce a mid-gap state. DBs can be created on this surface by the...

Spring 2015
This thesis is focused on the silicon-based anode materials for lithium-ion batteries (LIBs) as well as germanium-based electrode materials for sodium-ion batteries (NIBs). In our first attempt we studied electrochemical cycling stability and degradation mechanisms of silicon nanowires (SiNWs)...
