Abstract:
A series of unfunctionalised and hydroxyl functionalised ionic liquids were synthesised with the aim of developing an ionic liquid based sensing platform. The electrochemical, and interfacial properties, were investigated and characterised to understand their use in a liquid-liquid, ITIES, platform. Electrochemical cells were designed and tested against model systems before the potential windows for the ionic liquid, ITIES, systems were measured. The potential windows were substantially wider than those previously reported. Initial agitation experiments with cytochrome-c showed promising resul

Abstract:
Metal cleanliness is a major concern of today's aluminium industry. The metal cleanliness is related to the number and size of nonmetallic inclusions suspended in the liquid metal. A sensor, submerged in a liquid metal bath, produces a characteristic electrical signal during the passage of a particle through its Electric Sensing Zone (ESZ). On-line analysis of these signals enable melt particle size distribution to the derived. The present study focuses on signals obtained during application of such a sensor to aluminium melts.<br>Both the sensor and the preprocessing stages of the signal are

Abstract:
Dans cette thèse, nous présentons une étude approfondie des résonateurs à disques optomécaniques ultra-haute fréquence, en fonctionnement dans divers environnements liquides. L'objectif du travail était de développer des techniques expérimentales optiques et des modèles théoriques pour étudier les interactions fluide-structure dans des dispositifs micro ou nanométriques vibrants, ayant des applications potentielles en fluidique, en détection pour le biomédical et en science des matériaux. Nous avons appliqué des techniques de transduction optomécaniques à des résonateurs à disque en silicium p

Abstract:
Le dihydrogène, communément appelé hydrogène, est un gaz dangereux qui devient explosif au-dessus d'une concentration de 4% dans l'air. Par conséquent, de nombreuses applications pour lesquelles l'hydrogène est utilisé ou produit nécessitent des capteurs d'hydrogène pour s'assurer que cette limite n'est jamais atteinte. Ces applications comprennent la surveillance des déchets radioactifs, la production d'énergie propre ou plus généralement la surveillance des gaz industriels. La plupart des dispositifs de détection existants actuellement sur le marché sont basés sur l'utilisation d'un composé

碩士<br>國立聯合大學<br>光電工程學系碩士班<br>101<br>In this thesis, the taper fibers, which can be fabricated by a commercial fusion splicer, are used to achieve liquid level sensors. Moreover, we investigate the sensor structure and measurement approaches. The interferometer based on a taper fiber is quite sensitive. For the interference spectra, the power and wavelength of the peak are varied intensely as the taper fiber senses a slight variation from external environment. Therefore, the taper fiber is suitable for a sensor to sense a slight variation in the surroundings. In the work, by using the taper fib
