A Microreactor System For Measuring Size Selectivity In Porous Wo3 Sensor Materials, Meng Lu
A Microreactor System For Measuring Size Selectivity In Porous Wo3 Sensor Materials, Meng Lu
Electronic Theses and Dissertations
Our interest in studying reactions catalyzed by high surface area W03 powders is based on their potential application as the active material in sensors for low level (ppb) detection of flammable or toxic gases. A series of porous W03 powders with both meso- and micro-porosity have been synthesized by Waghe and Tripp. Preliminary results of the response of sensors fabricated from these materials indicated the possibility of size selectivity on the molecular scale. To provide support for the hypothesis of size selectivity and understand the reaction kinetics of alcohols over the new porous W03 powders for sensor …
Act/Sger: Atomic Layer Deposition Of Nitrides On Nano-Particles For Enhanced Energy Conversion To Combat Terrorism, William J. Desisto
Act/Sger: Atomic Layer Deposition Of Nitrides On Nano-Particles For Enhanced Energy Conversion To Combat Terrorism, William J. Desisto
University of Maine Office of Research Administration: Grant Reports
William J. DeSisto, University of Maine, will apply atomic layer deposition reactions to passivate nanoparticles. These coated nanoparticles will be used in next-generation, high energy density, compact energy storage devices. Initial experiments will focus on coating nano-sized lithium-ion battery anodes with titanium nitride. Miniaturized batteries using these anodes will be fabricated and evaluated by industrial collaborators at Yardley/Lithion Technical Products.
This award is supported jointly by the NSF Directorate for Mathematical and Physical Sciences and the Intelligence Community. The Approaches to Combat Terrorism Program supports new concepts in basic research and workforce development with the potential to contribute to national …
Magnetic Flux Sensor For Hearing And Application, Crystal R. Kenney
Magnetic Flux Sensor For Hearing And Application, Crystal R. Kenney
Electronic Theses and Dissertations
A 3-D microelectronic inductor has been fabricated and characterized for use as a magnetic flux sensor, also known as a telecoil, for a hearing aid application. This telecoil was fabricated in a 0.5pm CMOS process with three metal layers. The 3-D structure is more space efficient than conventional spiral inductors and allows for an optimal number of turns for the space available. The telecoil has an inductance of 80pH, a resistance of 34kR, and a capacitance of 275pF. The integrated telecoil acts as a magnetic flux sensor by picking up the magnetic signal fiom the phone speaker. The integrated telecoil …
