Abstract (sommario):

The work presented in this thesis involves the application of room temperature ionic liquids (RTILs) as solvents for use in electrochemical experiments. Initially, the fundamentals of electrochemistry is presented, followed by a comprehensive overview of RTILs in terms of their properties, applications and their behaviour as electrochemical solvents compared to conventional aprotic solvents. The results of 8 original studies are then presented as follows: X-Ray photoelectron spectroscopy is used to quantify the concentration of bromide ions in an ionic liquid, and is independently confirmed by

Abstract (sommario):

Formulation is a complex science. Many functional molecules require formulation to enhance their aqueous solubility or to promote and protect their function. Understanding the interaction between the formulation components is a necessary first step in that process. This project focuses predominantly on quantifying the interactions (synergistic and antagonistic) that arise when a triblock copolymer Pluronic (PI23) is mixed with the anionic surfactant sodium dodecyl sulfate (SDS), in the presence of the cosolvent, ethanol. The interaction between PI23 and SDS is synergistic, and leads to the for

Abstract (sommario):

A steady state analytical solution for MOSFET (metal oxide semiconductor field effect transistor) channel temperature estimation has been derived and the analytical model has been used to develop a software tool called HeatMOS©. HeatMOS© estimates the MOSFET channel temperature based on information from the device layout and an industry standard BSIM3 compact model. The steady state solution is an approximation for the channel temperature distribution along its length. The HeatMOS© model has been designed to be integrated into a VLSI CAD flow to predict the steady state temperature of a full m

Abstract (sommario):

At standard pressure, the chemical shift of Xe-129 in an aqueous solution of xenon exhibits a maximum as a function of temperature at 311 K, which is in contrast to the well-known density maximum of water at 277 K. In the present work, this phenomenon is studied by means of a molecular dynamics simulation, where the xenon chemical shift is computed quantum-chemically for snapshots of the simulation trajectory. Also, a simple semianalytical model is developed in which the water around the xenon atom is interpreted to form a shell of uniform density. Both approaches are found to be able to quali

Borides and carbides of tantalum and hafnium are of great interest due to their ultrahigh temperature applications. Properties of these ceramics including oxidation resistance and mechanical properties might be further improved through solid solution/composite formation. Synthesis of single-phase TaxHf1-xC and TaxHf1-xB2 solid solution powders including nanopowders via carbothermal reduction (CTR) is complicated due to noticeable difference in reactivity of parent oxides with carbon, and also the low solubility of those oxides in each other. Moreover, for TaC-HfC system the solid solution may

This thesis describes the electrical behaviour of solution-processed zinc oxide thin film transistors (ZnO TFTs) fabricated at low temperature. First, the electrical properties of solution-processed ZnO films are reported. Spin-coated ZnO films annealed at 150 °C exhibit significant sensitivity to the ambient environment. However, their stability can be improved by hydrogen plasma treatment. Zinc oxide TFTs (channel width/length = 4000/200 μm) fabricated by chemical spray pyrolysis at the low process temperature of 140 °C are investigated. The resulting transistors exhibit a saturation mobilit

In the solar energy arena, there is a considerable market for portable, lightweight, and flexible solutions for solar energy harvesting, in which organic and perovskite photovoltaics are two promising candidates. Cathode-bottom device architecture is commonly used in organic and perovskite photovoltaics due to its long-term stability. However, in this structure the electron transport layer (ETL) adjacent to the cathode commonly requires high temperature annealing, which limits the use of flexible substrates.

Interdiffusion in multicomponent-multiphase alloys is commonly encountered in many materials systems.

In addition, interdiffusion processes often control degradation and failure of these materials systems. Enhanced performance and reliable durability always requires a detailed understanding of interdiffusion. In this study, ternary

碩士<br>明志科技大學<br>材料工程研究所<br>100<br>This study present a simple method to produce a lot of carbon as micro and nanostructure in aqueous solution at low temperature (85 °C). The structures have been observed two basic units by transmission electron microscopy (TEM): thin carbon nanoribbons, monolayer graphene. This method addition to obtain two basic units and found that synthesize multi-wall carbon nanotube (MWCNTs) without catalyst and carbon basin-shape structure. We further found that the carbon nanoribbons can self-assembly to form ribbon type of graphite nanofibers, carbon nanorings and MW

碩士<br>國立臺北科技大學<br>材料科學與工程研究所<br>95<br>In this study, zinc oxide nanowires was successfully grown on ZnO/Si substrate using low-temperature aqueous solution method. We firstly study the influences of the ZnO buffer layer on the Si substrate on the crystal direction of zinc oxide nanowires. Then the effects of solution concentration, growth time, and the ratio of Zn(NO3)2 and C6H12N4 in the solution on the morphology and size of zinc oxide nanowires were also investigated. Our experimental results indicate that the zinc oxide nanowires have uniform C-axis preferred orientation when the zinc oxid

碩士<br>國立虎尾科技大學<br>光電與材料科技研究所<br>95<br>In this study, we have made efforts to develop a novel chemical-liquid deposition technique for the low-temperature growth of highly oriented and densely packed ZnO nanorods on substrates through homogeneous nucleation of the zinc oxide seed layer for growing well-aligned ZnO nanorod arrays on the substrate. The results exhibite that the size of nanorod strongly depends on [Zn2+] concentration. Furthermore, the as-grown vertical ZnO nanowires were characterized by XRD, FE-SEM, Micro-Ranman and Micro-PL. Where the morphology of ZnO seed layers, pH, growth t

碩士<br>國立東華大學<br>材料科學與工程學系<br>100<br>In this study, zinc nitrate hydrate (Zn(NO3)2·6H2O) and equimolar hexamethylenetetramine (C6H12N4, HMT) aqueous solution is used as precursors. ZnO nanorods arrays are grown on different substrates from low temperature(<100 °C) chemical synthesis method. ZnO nanorods can be grown on arbitrary substrates with introducing a ~10 nm-thick of seed layer on substrates before the growth of ZnO nanorods. The ZnO nanopartical seeds are prepared by thermally decomposing of zinc acetate dihydrate (Zn(CH3COO)2·2H2O) colloid solution in ethanol at 200-350 °C. The diamete

碩士<br>國立中正大學<br>光機電整合工程所<br>98<br>In this thesis, ZnO nanorods were fabricated by two-step process. In the first instance, the substrate was pre-coated seed layer by sol-gel spin-coating method before growing nanorods . Secondly, ZnO nanorods thin film were synthesized by Chemical bath deposition (CBD). ZnO nanorods thin films were measured by SEM, XRD and photo- luminescence spectra to get there physical characteristic. We fabricated the field effective transistor by using these ZnO nanorods thin films and measured I-V curve of these transistors. We obtained the ZnO nanorods thin film with fi
