Colloidal semiconductor nanocrystals as nanoscale emissive probes in light emitting diodes and cell biology
(Massachusetts Institute of Technology, 2008)
This thesis employs colloidal semiconductor nanocrystals (NCs) as nanoscale emissive probes to investigate the physics of light emitting diodes (LEDs), as well as to unveil properties of cells that conventional imaging ...
Ultrafast dynamic ellipsometry of laser driven shock waves
(Massachusetts Institute of Technology, 2008)
The experimental measurement technique of ultrafast dynamic ellipsometry (UDE) was developed for measuring material motion and changes in optical properties of samples under laser driven shock loading. Ultrafast dynamic ...
Real time density functional simulations of quantum scale conductance
(Massachusetts Institute of Technology, 2009)
We study electronic conductance through single molecules by subjecting a molecular junction to a time dependent potential and propagating the electronic state in real time using time-dependent density functional theory ...
Electronic signatures of large amplitude motions
(Massachusetts Institute of Technology, 2009)
In this thesis, I demonstrate that measurements of electronic-structure-induced splittings in the rotational spectrum of a vibrationally excited state can identify the nature and extent of the distortion of the equilibrium ...
Palladium-catalyzed C-N cross-coupling and application to the synthesis of delayed singlet emitters for OLED development
(Massachusetts Institute of Technology, 2014)
The studies in the present dissertation were aimed at developing and applying synthetic methods mediated by palladium catalysis. In Chapters 1 and 2, the palladium-catalyzed amidation and amination of five-membered ...
Development of new parameters for structure determination and dynamic investigations on biomacromolecules by NMR
(Massachusetts Institute of Technology, 2005)
Nuclear magnetic resonance (NMR) spectroscopy is unique in the content of structural as well as dynamic information that it can provide at atomic resolution. The aim of this PhD-thesis was to contribute to the understanding ...
Mechanistic investigation of polyhydroxybutyrate (PHB) synthases and elucidation of PHB biosynthesis and degradation process in Wautersia eutropha H16
(Massachusetts Institute of Technology, 2005)
Polyhydroxyalkanoate (PHA) synthase from various bacterial organisms is able to catalyze the polymerization of (R)-hydroxyalkanoate-CoAs into high molecular weight PHAs under nutrient- limited conditions in the presence ...
Exploring the reactivity of bacterial multicomponent monooxygenases
(Massachusetts Institute of Technology, 2010)
Chapter 1. Introduction: The Reactivity of Bacterial Multicomponent Monooxygenases Bacterial multicomponent monooxygenases constitute a remarkable family of enzymes that oxidize small, inert hydrocarbon substrates using ...
Design, synthesis, and characterization of conjugated polymers and functional paramagnetic materials for dynamic nuclear polarization
(Massachusetts Institute of Technology, 2010)
The design, synthesis, and characterization of a series of radicals and biradicals for use as dynamic nuclear polarization (DNP) agents is described. DNP is a method to enhance the S/N-ratio in solid-state nuclear magnetic ...
Science and applications of infrared semiconductor nanocrystals
(Massachusetts Institute of Technology, 2010)
In this work we study several applications of semiconductor nanocrystals (NCs) with infrared band gaps. In the first half, we explore the physics of two systems with applications in NC based photovoltaics. The physics of ...
