Effects Of High Pressure On Photochemical Reactivity Of Organic Molecular Materials Probed By Vibrational Spectroscopy, Jiwen Guan Jul 2018

Effects Of High Pressure On Photochemical Reactivity Of Organic Molecular Materials Probed By Vibrational Spectroscopy, Jiwen Guan

Electronic Thesis and Dissertation Repository

Chemical transformations of molecular materials induced by high pressure and light radiation exhibit novel and intriguing aspects that have attracted much attention in recent years. Particularly, under the two stimuli, entire transformations of molecular species can be realized in condensed phases without employing additional chemical constraints, e.g., the need of solvents, catalysts or radical initiators. This new synthetic approach in chemistry therefore satisfies increasing need for production methods with reduced environmental impacts. Motivated by these promises, my Ph. D thesis focuses on this state-of-the-art branch of high-pressure photochemistry. Specifically, high pressure is employed to create the necessary reaction conditions to …


Compact Sensing Platforms Based On Localized Surface Plasmon Resonance, Zhutian Ding Apr 2018

Compact Sensing Platforms Based On Localized Surface Plasmon Resonance, Zhutian Ding

Electronic Thesis and Dissertation Repository

The development of plasmonic sensors mainly focuses on the improvement of their sensitivities that are approaching the theoretical limit. This work aims to propose, fabricate and characterize compact sensing platforms that are highly adaptable and easy to be miniaturized, without compromising their sensitivities. A plasmonic sensing system that allows the excitation of localized surface plasmon resonance (LSPR) by individual waveguide modes is presented conceptually and experimentally. Another compact sensing platform is proposed based on the ensemble hypothesis developed in this thesis.
