Abstract:

2D-Photonic crystal (PC) structures have enabled the fabrication of a wide variety of nanophotonic components. In perfect PCs, the exploitation of the enhanced local density of states at critical points of the band diagram has attracted considerable attention. Near these points, where the group velocity vanished, low curvature flat bands give rise to delocalized and stationary optical slow Bloch modes (or slow light modes). Properties of slow light make them good candidates to enhance Purcell or various non-linear effects or to design low-threshold lasers. Among these modes, slow Bloch modes (

Abstract:

The development of micro and nanoelectronics and nanophotonics needs novel characterization techniques to ensure higher quality of designed devices. The thesis describes a use of Scanning Near-field Optical Microscopy (SNOM) in dimensional control and in local investigation of diverse physical parameters. As example of its potential, the correlation between object topography and reflection measurement of capacitors is shown.

Abstract:

Jádrem této disertační práce bylo studovat optické a elektrické charakteristiky tenkovrstvých elektroluminiscenčních součástek řízených střídavým proudem (ACTFEL) a zejména vliv procesu stárnutí luminiforů na jejich optické a elektrické vlastnosti. Cílem této studie měl být příspěvek ke zvýšení celkové účinnosti luminoforů, vyjádřené pomocí jasu, účinnosti a stability. Vzhledem k tomu, že současnou dominantní technologií plochých obrazovek je LCD, musí se další alternativní technologie plošných displejů porovnávat s LCD. Výhodou ACTFEL displejů proti LCD je lepší rozlišení, větší teplotní rozs

Abstract:

Tuberculosis is a common and deadly disease caused by the Gram-positive bacteria Mycobacterium tuberculosis. Due to the unique nature of the extracytoplasmic localization of proteins in mycobacteria, specialized secretion systems are essential. Recent studies have identified a novel secretion pathway termed the ESX-1 (or Snm) secretion system. This system is known to secrete two virulence factors, ESAT-6 and CFP-10. The ESX-1 system is comprised of at least three core-components, Rv3870, Rv3871 and Rv3877. Rv3877 is an integral membrane protein, and possibly creates a translocation channel w

Abstract:

A conspicuous feature of plants responding to pathogen invasion is the synthesis of nitric oxide (NO), a redox signal. NO regulates protein function by S-nitrosylation, the addition of an NO moiety to a cysteine thiol to form an S-nitrosothiol. A key theme of NO function is reprogramming plant immune-related gene expression. However, it is still not clear how the NO signal is translated into transcriptional changes. Here we explored the potential role of a sub-group of SNO Regulated Genes (SRGs) uncovered by global expression profiling. Firstly, transgenic plants containing the SRG1 or SRG3 pr

The main objectives of this PhD thesis are the identification of the snow avalanche release areas and the snow avalanche flow regime characterization with the use of seismic data. We aim to search for new methods for conducting detailed studies of the seismic signal generated by snow avalanches, considered as a moving seismic source. One of the main bases for achieving these objectives is to use widely tested seismological methods designed for the study of single seismic sources.

However, during the development period, it is accompanied by the generation of pollution sources. Therefore, it is necessary to improve the environmental pollution problem and improve the impact of pollutants on harmful substances, because chemical pollutants may contain carcinogenic components and substances harmful to the human, among which photocatalyst catalysis technology is one of the effective methods for improving. For example, photocatalyst catalysis technolog

碩士<br>國立屏東科技大學<br>機械工程系所<br>97<br>Recently, mesostructured materials with high surface areas and large pore sizes have attracted much attention because of their potential applications. In this study, mesoporous SnO2 was prepared by sol-gel process and the synthesis was accomplished by using triblock copolymer as the template, and SnCl4‧5H2O as the inorganic precursor. The effects of triblock copolymer additives, NH4OH additives, water and calcining temperatures on the structure of mesoporous SnO2 were investigated by TGA, X-ray, SEM, FTIR, TEM and BET analyses.

Morphology of SnO2 nanowire arrays were observed with field emission scanning electron microscopy (FE-SEM). The crystal structures of the nanowires were identified by X-ray diffraction (XRD) utilizing Cu Kα radiation. Chemical composition of the as-prepared SnO2 nanowire arrays were analyzed by energy dispersive spectrometer (EDS).

One of the major crisis faced by marketing Oncidesa is its dull appearance of florets and it has remained unchanged for a very long time in any aspect of colors. Currently, the Oncidesa cut flower market is facing a new demand for a new spectrum of colors. With the aid of our previous study, we have devloped a white floret Oncidesa through RNA interference technology. However, one of the major concern deemed by the government
