Quantitative analysis of carbon fluxes for fat biosynthesis in wild-type and IRS-1 knockout brown adipocytes
(Massachusetts Institute of Technology, 2005)Excessive fat synthesis and the subsequent dysregulation of lipid metabolism constitute the major pathological factors of obesity and type 2 diabetes through triggering insulin resistance. Thus, controlling fat synthesis ... -
Quantum chemistry for spectroscopy : a tale of three spins (S = 0, 1/2, and 1)
(Massachusetts Institute of Technology, 2007)Three special topics in the field of molecular spectroscopy are investigated using a variety of computational techniques. First, large-amplitude vibrational motions on ground-state singlet (S0) potential energy surfaces ... -
Quantum dot-based nanomaterials for biological imaging
(Massachusetts Institute of Technology, 2006)Quantum dot-based fluorescent probes were synthesized and applied to biological imaging in two distinct size regimes: (1) 100-1000 nm and (2) < 10 nm in diameter. The larger diameter range was accessed by doping CdSe/ZnS ... -
Quantum dynamics in condensed phases : charge carrier mobility, decoherence, and excitation energy transfer
(Massachusetts Institute of Technology, 2006)In this thesis, we develop analytical models for quantum systems and perform theoretical investigations on several dynamical processes in condensed phases. First, we study charge-carrier mobilities in organic molecular ... -
Quantum mechanical studies of Heisenberg antiferromagnetic spin chains

Rational design and directed evolution of probe ligases for site-specific protein labeling and live-cell imaging
(Massachusetts Institute of Technology, 2012)Chemical fluorophores have superior photophysical properties to fluorescent proteins and are much smaller. However, in order to use these probes for live-cell protein imaging, highly specific labeling methods are required. ... -
Rational design and synthesis of new oxide ion conductors
(Massachusetts Institute of Technology, 1996) -
Rational design of polymer networks and bottlebrush block copolymers
(Massachusetts Institute of Technology, 2017)Chapter 1: Introduction to Polymer Networks and Bottlebrush Block Copolymers We introduce polymer networks and the contribution of this author's thesis in the context of new polymer gel design and analysis of topological ... -
Rational designs of polymers for interfacial assemblies and intrinsic porosity
(Massachusetts Institute of Technology, 2019)In Chapter 1, we begin with a brief introduction of dynamic complex colloids and porous organic polymers with their applications in different areas. In Chapter 2, we describe the interfacial polymerization on dynamic complex ... -
Re-targeting of anthrax toxin binding for immunomodulation and targeted cancer therapy
(Massachusetts Institute of Technology, 2020)The intracellular delivery of cytotoxic proteins is a longstanding goal in drug development. This is challenging due to biological membranes, which prevent facile entry of macromolecules into the cellular cytosol. Anthrax, ... -

Reactions of S-nitrosothiols with biomimetic iron complexes and other transition metals
(Massachusetts Institute of Technology, 2014)Chapter 1. Bioinorganic Chemistry of Nitric Oxide and S-Nitrosothiols The interplay of nitric oxide (NO), biological thiols, and metals has been a topic of intense study since the discovery of NO as the endothelium-derived ... -
The reactivity and cation exchange of MOF-5
(Massachusetts Institute of Technology, 2015)The aim of this thesis is to demonstrate that the inorganic clusters within MOF-5 can be derivatized with redox-active cations for subsequent use in coordination chemistry and small-molecule activation. Rather than reproduce ... -
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 ... -
Real-time observations of materials under dynamic loading conditions at the micron scale
(Massachusetts Institute of Technology, 2016)New methods are introduced for direct real-time observations of materials under dynamic loading. Traditionally, converging shock waves, which are of great interest for studying fundamental aspects of behavior of materials ...
