Terahertz imaging and spectroscopy of carbon-based and semiconductor nanostructures

Creator:: Tomaino, Joseph L.
Abstract:: This thesis will cover work that I have completed relating to the field of terahertz (THz) science. My work has consisted of generating tunable, narrowband THz pulses in a table-top optical setup and using both narrow- and broadband THz pulses to study various material systems. Broadband THz pulses were used...

Physiological, proteomic, and whole-genome transcriptional responses of Nitrosomonas europaea to heavy metals (Zn²⁺,Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide : identification of heavy metals and cyanide stress response genes

Creator:: Park, Sunhwa
Abstract:: Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...

Electronic and Optical Properties of Organic Semiconductors : Experiment and Simulation

Creator:: Johnson, Brian
Abstract:: The continued development of organic semiconductor materials relies on an understanding of the relationship between optoelectronic properties, molecular structure, and molecular interaction. Several detailed studies of electronic properties in functionalized polyacene materials are presented. A computational model which allows the extraction of charge generation and transport properties from experimental data...

Modeling, Fabrication, and Characterization of Magnetic Thin Films for Integrated Inductor and MRAM Applications

Creator:: Buford, Benjamin
Abstract:: Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM). The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...

Dynamics and Design of Green Fluorescent Protein-Inspired Superphotoacids and Red-Emitting Fluorophores with Transient Absorption and Femtosecond Stimulated Raman Spectroscopy

Creator:: Chen, Cheng
Abstract:: In the past decades, femtosecond stimulated Raman spectroscopy (FSRS) has been gaining tremendous popularity in fundamental sciences stemming from chemistry to biology. It is capable of capturing both equilibrium and non-equilibrium structural information across a broad range of timescales with simultaneously high temporal and spectral resolutions. Femtosecond transient absorption spectroscopy...

Surface Modification to Enhance Corrosion Resistance of Carbon Steels using Additive Manufacturing

Creator:: Murkute, Pratik V.
Abstract:: Low carbon steels (LCS) due to their high strength-to-cost ratio are one of the most ubiquitous materials used for a wide range of applications, including but not limited to automotive, construction, and transportation. However, the low corrosion resistance of LCS in neutral, acidic, or saline environments limits its utilization and...

Femtosecond Stimulated Raman Studies of Excited State Structural Events

Creator:: Tang, Longteng
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...

Exciton and Polariton Nature in Organic Crystals

Creator:: Van Schenck, Jonathan D. B.
Abstract:: Understanding the impact of inter-molecular orientation on the optical proper-ties of organic semiconductors is important for designing next-generation organic (opto)electronic and photonic devices. However, fundamental aspects of how various features of molecular packing in crystalline systems determine the nature and dynamics of excitons have been a subject of debate. Toward...
