Between environmental literature and ocean literature, Syaman Rapongan and Liao Hongji
No full textThe subject of the bachelor thesis is a literary analysis of selected works with oceanic subject matter by contemporary Taiwanese authors Syaman Rapongan (*1957) and Liao Hongji (*1957). Rapongan's novel The Eyes of the Sky (2012) and Liao Hongji's short story cycle Fishermen (1996) will be presented in the broader context of "bentu literature" (bentu wenxue; i.e., local Taiwanese literature) and closely related environmental and ocean literature. In the analytical part, the author will focus on the motivic construction in the work of Rapongan and Liao in relation to ocean and environmental themes. The main focus will be on the differences in the conception of the ocean and marine culture in Rapongan's work as a member of the indigenous tribe Tao, and Liao Hongji, whose origin is Han. The thesis further examines whether and how environmental and oceanic literature overlap, using Wu Mingyi's definition of environmental literature. Keywords Syaman Rapongan, Liao Hongji, ocean literature, environmental literature, bentu wenxu

Keywords Syaman Rapongan, Liao Hongji, ocean literature, environmental literature, bentu wenxuePředmětem bakalářské práce je literárně-vědná analýza vybraných děl s oceánskou tematikou současných tchajwanských autorů Syamana Rapongana (*1957) a Liao Hongjiho (*1957). Raponganův román Oči Nebes (2012, přel. Šimonová, 2017) a Liao Hongjiho povídkový cyklus Rybáři (1996, přel. Krámská, 2017) budou představeny v širším kontextu "literatury bentu" (bentu wenxue; tj. místní taiwanské literatury) a s ní úzce související environmentální a oceánské literatury. V analytické části se autorka zaměří na motivickou výstavbu v tvorbě Rapongana a Liaoa ve vztahu s oceánskou a environmentální tematikou. Hlavní důraz bude kladen na rozdíly v pojetí oceánu a mořské kultury v tvorbě Rapongana jako příslušníka kmene původních obyvatel Tao, a Liao Hongjiho, jehož původ je hanský. Práce dále zkoumá, zda a jak se proudy environmentální a oceánské literatury překrývají, při čemž pracuje s definicí environmentální literatury podle Wu Mingyiho.

Thermal bubble behaviour in liquid nitrogen under electric fields
No full textThis thesis describes thermally induced bubble behaviour changes in liquid nitrogen (LN2) under electric fields. Cryogenic liquids such as LN2 have been used not only as the coolant but also as the electrical insulator in superconducting and cryogenic
apparatus. However, bubbles are easily formed in these liquids by even moderate heating because of a narrow liquid temperature range and low boiling point. Bubbles
are considered to be one of the factors causing a reduction of the electrical insulation level. Consequently, bubble behaviour in electric fields is of great interest primarily in the study of prebreakdown and breakdown phenomena in the presence of thermally induced bubbles. In addition, a bubble can appear and its behaviour changes in a fluid under the influence of an electric field, and this is the main reason for boiling heat transfer enhancement which is related to thermal stability and heat transfer efficiency.Studies including single bubble behaviour and bubble column behaviour as well as boiling heat transfer enhancement due to changes in bubble behaviour under electric fields using different electrodes have been completed. Free thermal bubble motion and related characteristics in LN2 under a conductor-plane electrode have been experimentally studied. A model for bubble motion in this non-uniform electric field has been developed and is described. Compared with theoretical results, the experimental measurements are in good agreement. An rimental study into the behaviour of thermal bubbles between two plane-plane inclined electrodes has been completed. Using a stainless steel mesh-to-plane electrode system, experimental
investigations have been carried out to study the effect of uniform dc electric fields on the behaviour of a single thermal bubble in LN2. Bubble characteristics such as bubble
growth, deformation and bubble departure frequency have been experimentally evaluated. Finally, the electric field effects on boiling heat transfer of LN2 have been experimentally assessed. The obtained data is applicable to the design of LN2 cooled
high temperature superconductor power apparatus for both coolant and electrical insulation issues
Investigations into carbon nitrides and carbon nitride derivatives
No full textCarbon nitrides and carbon nitride derivatives are promising photocatalysts. The main focus of this thesis is the synthesis and characterization of various carbon nitrides (incompletely condensed melon, carbon nitride doped cesium titanate, ultra-long calcined melon, and OH-melem). Those carbon nitrides were then tested with regard to their photocatalytic properties.
In the first part of chapter 3 of this thesis, we focus on a material called ‘‘melem oligomer’’. Two different synthesis routes were applied (open system and half open system) and the composition and structure of this material was studied. Melem with two different crystalline structures and some amorphous residues were found in the product. We also tested the photocatalytic activity of melem oligomer and confirmed hydrogen production from water with a relatively low rate of 2 μmol g-1 h-1. In the second part of chapter 3, we synthesized ultra-long calcined melamine which may have a morphology similar to the ‘‘g-C3N4 nanosheets’’. We analyzed both the composition and structure and investigated the efficiency of the presumed g-C3N4 nanosheets for hydrogen production from water. Ultra-long calcined melamine showed the best photoactivity which is twice that of melon at 490 °C. This is most likely due to the interesting morphology and high surface area.
In chapter 4, melem oligomer was doped with cesium titanate in situ. Different calcination times were applied and various characterization techniques were used to investigate the composition, structure and morphology of the obtained materials. The efficiency of this hybrid photocatalyst for hydrogen production did not show higher photoactivity than the pure carbon nitrides except in the case of 16 h calcination which was the optimum calcination time overall.
In chapter 5, OH-melem with a composition close to 2-oxo-6,10-diamino-s-heptazine, which could be a precursor of oxygen-doped g-C3N4, was synthesized and characterized by various techniques. Crystallinity is rather low in this oxygen containing species. NMR spectra differ from melem or cyameluric acid and XPS results confirm the presence of C=O groups.
Overall, different carbon nitrides and carbon nitride derivatives were synthesized and chemically investigated to gain further knowledge on their synthesis, chemical properties and their resulting application as photocatalysts
Investigation of the residual stress in reaction-bonded SiC under irradiation
No full textThe development of reaction-bonded SiC (RB-SiC) for an application in nuclear reactor environments has been suspended for many years because of the possible swelling mismatch between SiC and Si under irradiation. Therefore, we studied the residual stresses in RB-SiC due to the irradiation-induced swelling mismatch and the mismatch between the coefficients of thermal expansion. The maximum irradiation-induced swelling stress for the amorphous state was obtained by irradiation with 2 MeV Au2+ ions (1 x 10(16) ions/cm(2)) at room temperature. Utilizing Raman piezo-spectroscopy, nanoindentation tests and thermal expansion coefficient measurements, we demonstrate that the irradiation-induced swelling stress is remarkably high at low temperatures, whereas the thermal stress becomes the dominant residual stress at medium (415 degrees C < T< 700 degrees C) or higher temperatures. By optimizing the residual Si content in the RB-SiC, the thermal stress and the irradiation-induced swelling stress can be adjusted and the initiation of cracks can be prevented.
