Tuning π-Conjugated Polymers with Heteroatoms: Synthesis of Polytellurophenes and Soluble Polyacetylenes
DownloadFall 2021
This Thesis describes the synthesis and investigation of π-conjugated oligomers and polymers with optoelectronic properties affected by the presence of a heteroatom. Two major classes of polymers are discussed: 1) polytellurophenes, where the backbone is formed by 5-membered heterocycles...

Surface modification of zirconium implants via electrochemical anodization and wet chemical techniques
DownloadFall 2011
Metals such as titanium (Ti) and zirconium (Zr) have been widely applied in the orthopaedic and orthodontic field for construction of joint replacement prostheses and teeth implants due to their lower cytotoxicity, excellent mechanical properties, and corrosion resistance. However, the current...

Development of MEMS-based Piezoresistive Three Dimensional Stress/Strain Sensor with Temperature Compensation
DownloadSpring 2020
In this research, a developed n-type piezoresistive three dimensional (3D) stress sensor with full temperature compensation is presented. The proposed sensing rosette benefits from the stress insensitivity of the full-circular n-type piezoresistor, oriented over (111) silicon plane, to detect...

Spring 2015
Supramolecular rosette nanotubes (RNTs) are obtained by the hierarchical self-assembly of mono and twin G^C building blocks. The mono G^C motif is a fused bicyclic ring of guanine and cytosine with six self-complementary sets of hydrogen bonding sites, while the twin G^C motif is a covalently...
