Intermolecular charge transfer between electron-rich donor and electron-poor acceptor molecules offer great promise in the development of novel, low-cost electronic materials. It is hypothesized that control over the intermolecular interactions and supramolecular self-assembly of these systems could tune electronic properties and discover new functions. To that end, a series of...
Demands in the aerospace, automotive and biomedical sectors for low-volume sheet metal parts made from materials with high specific strength are growing due to the needs imposed by rapid product development cycles, and personalized products to mention a few. However, high strength-to-weight ratio materials, such as Ti6Al4V, are usually difficult...
Composites of metal nanoparticles encapsulated by metal-organic frameworks (NP@MOFs) have recently emerged as intriguing heterogeneous catalysts for regioselective reactions. Sharing qualities of both zeolites and enzymes, these catalysts employ the pore system of a MOF to direct reactant access to the surface of nanoparticles. This dissertation seeks to better understand...
The recent development of quantum biology results in various breakthroughs in exploring the role of quantum physics in biological systems, as well as in observing and controlling light-matter interactions in biological materials on a fundamental quantum level. We seek to combine the concept of quantum biology with quantum optics to...
Recent years have witnessed success in using mathematical models to understand complex social phenomena. In this dissertation, we develop and apply two mathematical models in the area of urban productivity and political elections. ', 'First, we investigate the puzzling superlinear scaling behavior of many outputs in urban areas, such as...
Precise assessment of long-term aging and deterioration play a major role in life-time predictions of concrete structures. One of the primary challenges in studies of cementitious materials such as concrete comes from the fact that multiple chemical reactions are happening in parallel. Environmental conditions present another challenge as they can...
The phase-field crystal (PFC) model is an exciting new method for simulating crystalline materials with atomic resolution over diffusional time scales. Unfortunately, applications of the model have been severely limited by the requirement that novel free energies must be constructed for each new material of interest. This thesis describes three...
Meiosis is a specialized form of cell division where chromosomes are duplicated once and segregated twice, in order to reduce the chromosome number by half to generate haploid gametes. In contrast to mitosis, oocyte meiosis in many species occurs in the absence of centrosomes, the microtubule organizing centers that nucleate...
This dissertation studies three topics in labor and public economics. The first chapter examines the local economic consequences of prisons using two complementary approaches. The first uses the openings of 230 prisons during the 1990s across the entire United States, and the second uses a quasi-experimental strategy that compares winning...
Electrochemical energy storage devices have become increasingly relevant to the operation and sustainability of the modern world, as proliferation of mobile electronics, renewable electrical energy generators, electrical vehicles, and various high-tech bio-medical sensing device continues. The widespread need of easier to produce, better performing, and multifunctional energy storage materials in...
