A Study on Phase Change Materials at Low Thermal Mass with Micro-Electro-Mechanical Resonators
DownloadSpring 2020
Micro-electromechanical systems or MEMS is a modern technology used to create tiny, integrated devices or systems that combine mechanical and electrical components. These miniaturized devices can sense, control and actuate on the micro and nano scales, and generate observable effects on the macro...

Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and texture
DownloadSpring 2014
Structuring of material on the nanoscale is enabling new functional materials and improving existing technologies. Glancing angle deposition (GLAD) is a physical vapor deposition technique that enables thin film fabrication with engineered columnar structures on the (10 to 100) nm scales. In this...

An examination of linking and blocking procedures for use in deflection cantilever array-based protein detection
DownloadFall 2011
In this project common linking and blocking procedures were examined for use in multiplexed deflection cantilever array-based detection of proteins. A human interferon gamma (INF-γ) enzyme-linked immunosorbent assay (ELISA) kit was used to evaluate the effectiveness of the linking and blocking...

Fall 2011
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Combination of AC electrothermal and Dielectrophoresis realized by 3D Electrodes to Concentrate Particles
Download2022-06-01
Fathy, Jino, Wang, Ziying, Lai, Yongjun
In this paper, a particle microconcentrator is designed and simulated that works by combining the AC electrothermal (ACET) and Dielectrophoresis (DEP) forces. The microconcentrator consists of a PMMA channel with copper electrodes on the walls and bottom of the channel. On each side of the...

Design and Fabrication of Micro-electro-mechanical Systems Actuators for Application in External Cavity Tunable Lasers
DownloadFall 2014
The limited availability of rugged and economical infra-red laser sources that can be tuned over a certain wavelength range is still a bottleneck for widespread application of spectroscopic methods to environmental, industrial, and medical trace gas monitoring. Conventional semiconductor lasers...
