Patterning Layer -By -Layer Self -Assembled Multilayer By Lithography And Its Applications To Thin Film Devices, Feng Hua

Doctoral Dissertations

Nanoparticles are exciting materials because they exhibit unique electronic, catalytic, and optical properties. As a novel and promising nanobuilding block, it attracts considerable research efforts in its integration into a wide variety of thin film devices.

Nanoparticles were adsorbed onto the substrate with layer-by-layer self-assembly which becomes of great interest due to its suitability in colloid particle assembly. Without extremely high temperatures and sophisticated equipment, molecularly organized films in an exactly pre-designed order can grow on almost all the substrates in nature.

Two approaches generating spatially separated patterns comprised of nanoparticles are demonstrated, as well as two approaches patterning more …

Design And Fabrication Of A Novel Linear Oscillating Conventional Micro Air Pump, Shi-Je Wu

Doctoral Dissertations

A novel permanent magnetically and electro-magnetically powered, linear oscillating conventional micro air pump was designed, fabricated and characterized. This new pump might be used in a wrist-type blood pressure monitor or other similar devices that require high air pressure discharge. Factors considered in designing this micro air pump include feature size (especially the thickness), operation voltage, efficiency, heat transfer, noise and weight. For evaluating the feasibility of this novel design, basic performance calculations and ANSYS magnetic flux simulations had been conducted before the first prototype was made. Both theoretical calculations and simulation results show that this novel design meets the …

Effects Of Diabetes And Aging On Posture And Acceleration Thresholds During Lateral Translations, Samantha Jean Richerson

Doctoral Dissertations

Research objectives. One source of falls in the elderly may be an inability to sufficiently adjust to transient postural perturbations or slips. Identifying useful predictors of fall potential, as well as factors that affect the ability of an individual to detect a movement of the standing support surface may provide insight into postural stability and methods to increase stability in elders. To do this, acceleration thresholds to short, precise, lateral platform translations and the resultant psychophysical responses of adults with early Type 2 diabetes to age-matched controls and young adults were measured.

Methods. Using an innovative SLIP-FALLS platform, …
