Direct measurement and analysis of cyclohexadienyl oxidation
(Massachusetts Institute of Technology, 2005)
The oxidation of cyclohexadienyl radical (c-C₆H₇) and similar resonantly stabilized radicals are important in an astonishing array of processes in nature. Cyclohexadienyl radical has been postulated to be significant in a ...
DNA hybridization : fundamental studies and applications in directed assembly
(Massachusetts Institute of Technology, 2005)
Programmed self-assembly using non-covalent DNA-DNA interactions is a promising technique for the creation of next-generation functional devices for electronic, optical, and magnetic applications. This thesis develops the ...
PEO-containing copolymers as polyurethane soft segments in the development of high performance materials
(Massachusetts Institute of Technology, 2005)
Silk-inspired segmented polyurethanes containing flexible, hydrophilic segments with crystalline and liquid crystalline moieties were developed to mimic the hierarchical morphology of the continuous domain in and the ...
Molecular simulation of crystal growth in alkane and polyethylene melts
(Massachusetts Institute of Technology, 2005)
Molecular simulation has become a very powerful tool for understanding the process of polymer crystallization. By using carefully constructed simulations, one can independently observe the two phenomena responsible for ...
Chemical vapor deposition of organosilicon and sacrificial polymer thin films
(Massachusetts Institute of Technology, 2005)
Chemical vapor deposition (CVD) produced films for a wide array of applications from a variety of organosilicon and organic precursors. The structure and properties of thin films were controlled by varying processing ...
Reaction mechanisms for catalytic partial oxidation systems : application to ethylene epoxidation
(Massachusetts Institute of Technology, 2005)
With the rapid advances in kinetic modeling, building elementary surface mechanisms have become vital to understand the complex chemistry for catalytic partial oxidation systems. Given that there is selected experimental ...
Biological applications of weal polyelectrolyte multilayers
(Massachusetts Institute of Technology, 2005)
This thesis research focused on biological applications of ultra-thin weak polyelectrolyte multilayers with specific emphasis on cell patterning, drug delivery, and antibacterial coatings. All of these very different ...
Design of a viable homogeneous-charge compression-ignition (HCCI) engine : a computational study with detailed chemical kinetics
(Massachusetts Institute of Technology, 2005)
The homogeneous-charge compression-ignition (HCCI) engine is a novel engine technology with the potential to substantially lower emissions from automotive sources. HCCI engines use lean-premixed combustion to achieve good ...
Multiphase flow and control of fluid path in microsystems
(Massachusetts Institute of Technology, 2005)
Miniaturized chemical-systems are expected to have advantages of handling, portability, cost, speed, reproducibility and safety. Control of fluid path in small channels between processes in a chemical/biological network ...
Layer-by-layer surface manipulation and biointegration of quantum dots : assembly of nanostructured DNA delivery vehicles
(Massachusetts Institute of Technology, 2005)
Objectives: The aims of this investigation are to (i) prepare hybrid quantum dot (QD)-polymer compleses, (ii) maniplulate structural and chemical properties of the hybrids and characterize their effects on biocompatibility, ...
