    After the Disaster: Architecture and Ruination in Twentieth-Century Japan

    No full text
    Focusing on the compounding concerns of ruination between the Great Kantō Earthquake of 1923 and the postwar redevelopment of urban Japan, this dissertation examines Japan’s twentieth-century history through mapping, architectural experimentation, critical visual media and architectural writing to detail a narrative of evolving architectural theory and practice and its lasting consequences on Japan’s urban environment. The findings of this dissertation elucidate the reciprocal (and occasionally competing) advances in architectural thinking, technological culture, and governmental practice deployed in disaster’s wake. Chapter One details a heretofore unknown history of Japanese architectural experimentation, a line of inquiry which contributes to the ‘promise’ of residential reconstruction after the earlier disaster of the 1923 earthquake that subsequently contributes to the destructive power of aerial bombardment during the Pacific War when the results of this experimentation are collected by American and British war planners and utilized to perfect their incendiary campaigns. A ‘bridge’ chapter follows that documents the ways in which the experimental approach to protection in Japan is confounded by the experiments in architectural aggression and bombardment by allied forces that subsequently decimated urban Japan. Chapter Two compares American and Japanese government mapping and evaluation projects conducted at the end of 1945, viewed through concerns about anomaly and scientific vision to argue for the mapping and visualization of wartime disaster as an extended encounter with the sublime. The chapter examines specific photographic representations and documentation of urban disaster and the ways in which this informs a critical appreciation of the ruin. The ‘bridge’ chapter after this exploration juxtaposes postwar documentation with the literary writings of Ishikawa Jun, Sakaguchi Ango, and Sata Ineko (all writing in 1945) as a pre-amble to the critical architectural writing on ruins of Isozaki Arata alongside the critical conceptualization of ruins by Hino Keizō that form the focus of Chapter Three. Through extensive engagement with the writings of Isozaki and Hino, this final chapter elaborates the transitions of a focus on the ruin as an object of study in the 1920s through its manifestation as experience in the postwar 1940s and finally into a productive hermeneutic and lasting ontology in the form of ruination

    Havana (after)life: Touring the entropics

    No full text
    While Havana's status as the 'Pearl of the Caribbean' dissipated in 1959, Cuba and its capital survived the subsequent 30 years as a relatively prosperous Caribbean nation under communist control. Soviet communism's dissolution in 1989 left Cuba's international and economic support structure in tatters. Extreme rationing returned, imports and exports fell, and life as usual came to a grinding halt. To save its economy and future, Cuba turned back its clock to a former source of international attention: tourism. But what form can tourism take in this remaining communist stronghold? How can Havana embrace a new economic engine without decimating its most enticing features and avoid turning itself into a Caribbean tourist ghetto? As the fragility of Castro's hold on the island becomes ever more apparent, how will the changing power structure of Cuba's government affect relations on the world stage? When greenbacks enter red cities, what happens next

    Engineering polymer-nanocellulose systems towards sustainable devices

    This thesis explores nanocellulose-polymer systems for use in organic electronics applications. Each chapter provides an understanding of the interactions between polymers and cellulose nanocrystals (CNCs) that give rise to desirable morphologies and optoelectronic properties, which can be used in the design of advanced electronic materials. Chapter 2 presents a proof-of-concept study looking at the compatibility and templating ability of CNCs with a water-soluble semiconducting polymer. The liquid crystal phase behavior of the blended system and its effect on semiconducting polymer alignment are explored. Chapter 3 expands on this work; a temperature-switchable liquid crystal template is developed by grafting a thermoresponsive polymer from the ends of the CNCs. The effect of the polymer grafting morphology on the degree and reversibility of the thermal “switch” is studied. Finally, Chapter 4 revisits the topic of semiconducting polymer organization. CNCs are grafted with polymers of varying surface energies and are blended with a benchmark semiconducting polymer. The effect of the CNC surface chemistry on the self-assembly of the semiconducting polymer is investigated. Chapter 5 summarizes the major findings of these three chapters and provides suggestions for future work.Ph.D

    Thermally switchable liquid crystals based on cellulose nanocrystals with patchy polymer grafts

    Get PDF
    A thermally “switchable” liquid-crystalline (LC) phase is observed in aqueous suspensions of cellulose nanocrystals (CNCs) featuring patchy grafts of the thermoresponsive polymer poly(N-isopropylacrylamide) (PNIPAM). “Patchy” polymer decoration of the CNCs is achieved by preferential attachment of an atom transfer radical polymerization (ATRP) initiator to the ends of the rods and subsequent surface-initiated ATRP. The patchy PNIPAM-grafted CNCs display a higher colloidal stability above the lower critical solution temperature (LCST) of PNIPAM than CNCs decorated with PNIPAM in a brush-like manner. A 10 wt% suspension of the “patchy” PNIPAM-modified CNCs displays birefringence at room temperature, indicating the presence of an LC phase. When heated above the LCST of PNIPAM, the birefringence disappears, indicating the transition to an isotropic phase. This switching is reversible and appears to be driven by the collapse of the PNIPAM chains above the LCST, causing a reduction of the rods' packing density and an increase in translational and rotational freedom. Suspensions of the “brush” PNIPAM-modified CNCs display a different behavior. Heating above the LCST causes phase separation, likely because the chain collapse renders the particles more hydrophobic. The thermal switching observed for the “patchy” PNIPAM-modified CNCs is unprecedented and possibly useful for sensing and smart packaging applications.Peer ReviewedPostprint (updated version
