Abstract:

This research reports on the fabrication and characterization of integrated dual nanometer-sized electrodes. The electrodes are made of closely spaced nanometer-sized platinum and gold achieved by inserting and pulling platinum wire in cylindrical glass pipette plated with gold. Cyclic voltammetry has been used to characterize the electrodes. Our results show that both electrodes can work individually and can accomplish generation/collection experiments. Factors that may affect the performance of the electrodes as well as formation mechanism of the gold film by electroless plating are discusse

Abstract:

In NiTi, a reversible thermoelastic martensitic transformation can be induced by temperature or stress between a cubic (B2) austenite phase and a monoclinic (B19') martensite phase. Ni-rich binary compositions are cubic at room temperature (requiring stress or cooling to transform to the monoclinic phase), while Ti-rich binary compositions are monoclinic at room temperature (requiring heating to transform to the cubic phase). The stress induced transformation results in the superelastic effect, while the thermally induced transformation is associated with strain recovery that results in the sh

Martensite-to-Beta transformation temperatures of CuAlNiMn and CuAlNi shape memory alloys has been determined by differential scanning calorimetry (DSC).

Therefore, as quenched alloy samples were thermally cycled for three times in DSC prior to ageing to obtain thermally stable and reproducible transformation temperatures and to eliminate the anomalous effect of bet

The 7-Ag₂Al phase in the Al-Ag system was used as the reference system and its misfit was controlled by ternary additions of Mg and Cu. The addition of 0.S1 at% Mg was found to increase the misfit from 0.8% for the binary to 1.11%. Cu additions on the other hand, reduced the misfit by 0.38% for Cu concentrations up to 0.51 at%.

Shape memory alloys (SMAs) provide exciting opportunities for miniature actuation systems. As SMA actuators are scaled down in size, cooling increases and bandwidth, improves. However, the inclusion of a bias element with which to cycle the SMA actuator becomes difficult at very small scales. One technique used to avoid the necessity of having to include a separate bias element is the use of local annealing to fabricate a monolithic device out of nickel titanium (NiTi). The actuator geometry is machined out of a single piece of non-annealed NiTi. After locally annealing a por

The ‘missing wedge’ is a long-standing problem in electron tomography, caused by the use of slab-like flat specimens, which increase in thickness when tilted to high angles. Attempts have been made to reduce the undesirable effects caused by the missing wedge, but the problem remains, particularly for the radiation-sensitive frozen-hydrated specimens used for high resolution imaging. Specimens with cylindrical symmetry offer a way to overcome this problem, since the thickness remains constant at all viewing angles.

Abstract:

The Orbitrap is a mass analyzer that employs an electrostatic field to confine ions. The mass of an ion is determined from the frequency of its axial oscillations in the Orbitrap. The Orbitrap has high resolving power and accuracy. However, the electrodes of the Orbitrap have complicated curved shapes. As a consequence the Orbitrap is not easy to miniaturize. In this thesis we have proposed a class of easily machinable cylindrical-electrode structures to mimic the behavior of an Orbitrap. The proposed structure consists of a single cylinder and many coaxial equally spaced thick rings. A detail

碩士<br>崑山科技大學<br>機械工程研究所<br>94<br>This study was to design a plasma fuel converter and to investigate the effects of design parameters on the performance of this apparatus. The methodology was using a high voltage electric arc generator to ionize the hydrocarbon fuel and air mixture. The ionized gas was reformed into the hydrogen-rich gas. The system equipment included a plasma fuel converter, a fuel and an air supply system, a data acquisition system and a measuring system. The experimental parameters include O2/C ratio (0.2~0.6), fuel feeding rate (100 mL/min~500mL/min CH4), arc freque

碩士<br>大同工學院<br>材料科學(工程)研究所<br>81<br>The biocompatibility is one of the most important factors for the application in biomedical devuces. Surface graft poly- merization of acrylamide (AAm) or acrylic acid (AAc) onto the substrate followed by immobilization of protein is one of the efficacious methods for this purpose. However, this method is not feasible for the inorganic material since there are no fun- ctional groups on the surface to initiate the free radical graft polymerizat

碩士<br>南台科技大學<br>機械工程系<br>98<br>Due to the high consumption and the thermal stress problem about the small size of the electrode by micro-EDM process, the effect of area leads to the concentration of discharge energy and enhance the electrode wear rate. In the study, tool steel SKD11 is machined with by micro-EDM technique using nickel powder suspension dielectric oil and micro V shape tungsten carbide electrode. Effect of electrode wear rate, surface crack of nickel powder particles, concentration, and working parameters will be taken into consideration.. Experimental results show that electro

Abstract:

碩士<br>大同大學<br>機械工程學系(所)<br>102<br>The collection and manipulation of small objects is important in bioassays. One commonly used force to manipulate small objects is electroosmosis which has the advantages of easy fabrication and small power consumption. Many factors affect the electroosmosis like surface charge density, applied voltage and frequency. For ac electroosmosis, frequency affects flow pattern and particle collection. A planar electroosmosis chip is fabricated by patterned electrode with circular and rectangular electrode shape. Different size latex particles (0.5μm, 1μm, 2μ m, 3μm)
