Abstract:

This study developed an automated approach to understand plume and plate boundary interactions over time, investigating how flat slab and porphyry development are linked to formation mechanisms of major eastern Pacific Large Igneous Provinces (LIPs). Our method allows us to detail how the Shatsky-Hess conjugate collided with North America from 85 Ma, with the subducting front corresponding to porphyry development and matching divisions between shallow and flat slab areas. Our new formation model for the Enigma Ridge, conjugate to the Tuamotu Plateau, resolves problems for development of the Pe

Abstract:

The effects of thin silver films (15-210 angstroms) on the oxidation of copper alloy lead frames has been characterized. Silver films were deposited onto copper lead frames by immersion plating in a bath containing potassium silver cyanide, potassium cyanide, and a mercaptan inhibitor. The thickness of films was measured by microfocus x-ray fluorescence and cross-checked by Rutherford backscattering spectrometry. Lead frames coated with silver films were oxidized at 150 to 200°C in a controlled humidity oven. The amount of oxide formed was measured by an electrolytic reduction technique and cr

Abstract:

The threat of climate change has created a demand for superior energy storage devices. One application for them is regenerative braking in hybrid vehicles to reduce fuel consumption and greenhouse gas emissions. Instead of using brakes, the friction generated from turning electric motors charges batteries stops the vehicle. In turn, the batteries are used to accelerate the vehicle. Since braking time is short, batteries are imperfect for this application due to low rate of energy transfer (power). Supercapacitors are superior for power, but cost and amount of energy stored needs to be improved

Abstract:

The class of high Tc superconductors share one common structural aspect, the existence of planes of copper and oxygen ions. These planes are thought to be the source of the superconducting behaviour. They can be represented as a two-dimensional lattice of ions, which facilitates their study using numerical models. One such model is the t − J model. In most studies utilising numerical models, the planes have been considered isotropic. However, recent analysis of cuprate structure has illustrated that this may not be representative of the copper oxide planes. A number of cuprate structures exhib

Five materials, copper (two versions), iron, and armour plate steel (two versions) have been tested at different strain-rates and temperatures. All tests were in compression.

A wide selection of metals was examined so that comparisons could be drawn between modelling the behaviour of face centred and body centred cubic metals, and to carry out a broader investigation into how the results obtained were affected by the test methods.

Surface engineering with polymer brushes has become one of the most versatile techniques to tailor surface properties of substrates for a broad variety of (bio-) technological applications. We report on a new facile approach to prepare defined and dense polymer brushes on planar substrates by surface-initiated Cu(0) mediated controlled radical polymerization (SI-CuCRP) of numerous vinyl monomers using a copper plate at room temperature. The fabrication of a variety of homo-, block, gradient and patterned polymer brushes as well as polymer brush arrays is demonstrated. The SI-CuCRP was found to

The final product is a carbon nanofibre reinforced copper composite. Two different fibre structures are considered: platlet (PL) and herringbone (HB).

Abstract:

Porphyry copper systems occur along magmatic belts derived in subduction zones. Current understanding of their formation is restricted to overriding plate observations, resulting in a knowledge gap with processes occurring in the convergence zones through time. An association between key tectonic processes and the timing and location of these systems requires linking geological observations to plate tectonic subduction models. This thesis is connecting the evolution of subduction zones and downgoing slab properties with the history of porphyry ore deposition across the Americas by using spatio

Abstract:

abstract: An ongoing effort in the photovoltaic (PV) industry is to reduce the major manufacturing cost components of solar cells, the great majority of which are based on crystalline silicon (c-Si). This includes the substitution of screenprinted silver (Ag) cell contacts with alternative copper (Cu)-based contacts, usually applied with plating. Plated Cu contact schemes have been under study for many years with only minor traction in industrial production. One of the more commonly-cited barriers to the adoption of Cu-based contacts for photovoltaics is long-term reliability, as Cu is a signi

Abstract:

abstract: Nickel-Copper metallization for silicon solar cells offers a cost effective alternative to traditional screen printed silver paste technology. The main objective of this work is to study the formation of nickel silicide contacts with and without native silicon dioxide SiO2. The effect of native SiO2 on the silicide formation has been studied using Raman spectroscopy, Rutherford backscattering spectrometry and sheet resistance measurements which shows that SiO 2 acts as a diffusion barrier for silicidation at low temperatures of 350°C. At 400°C the presence of SiO2 results in

碩士<br>國立中興大學<br>化學工程學系所<br>105<br>In the past decades, lead (Pb) has been questioned about its impact on the issues of environmental protection. Environmental experts continue to warn that Pb has harmful effects on human health. So, in the 70s and 80s, the United States and many other countries have legislated against the use of Pb paint in the building regulations. However, the rapid increase in the number of electronic waste products brings new urgent issue in the Pb usage. In response to this increasingly serious environmental problem, the European Union in 2003 announced the Restriction of

We studied electroanalysis of copper screen-printed carbon electrode (CuSPE) modified by different clay minerals. The experimental results indicated four clay minerals amplified copper redox currents in 0.1M pH7 phorsphate buffer. Furthermore, Ferruginous smectite (SWa-1) and nontronite (NG-1) with octahedral Fe(III) had larger redox currents than Na-montmorillonite (SWy-1) and Kaolinite (KG-1). We observe

碩士<br>國立中興大學<br>獸醫學系<br>93<br>Abstract Identifying the origin of meat species represents a considerable problem for food analysts and those seeking to comply with religious regulations. Consumers demand quality products that are honestly-labeled to assure meat safety and fair pricing. Therefore, there has been a need for a fast and routinely applicable meat species identification system. Here we have developed a rapid, inexpensive, and reliable technique which combines high-performance liquid chromatography and the electrochemical detection (HPLC-EC) with coppernanoparticle plated electrod

We used electrochemical d.c. polarization measurements performed with a rotating disk electrode to investigate several kinds of corrosion environments on CMP of copper-plated films and to study the conditions of passivation reactions, oxidizer and inhibitor on the sample.

First, in order to prevent the oxidation of the joining surface in the welding process, an aluminum sheet (10 mm thick) was machined to form a rectangular slot of 25 mm wide on its center region to accommodate a copper sheet (3 mm thick). Four edges of copper sheet were welded by the friction stir butt welding using a pinless tool as a pretreatment. Second, effects of rotational s
