Design Optimization Of Polymer Heat Exchanger For Automated Household-Scale Solar Water Pasteurizer, David C. Denkenberger, Joshua M. Pearce

Department of Materials Science and Engineering Publications

A promising approach to reducing the >870,000 deaths/year globally from unsafe water is flow-through solar water pasteurization systems (SWPs). Unfortunately, demonstrated systems have high capital costs, which limits access for the poor. The most expensive component of such systems is the heat exchanger (HX). Thus, this study focuses on cost optimization of HX designs for flow-through SWPs using high-effectiveness polymer microchannel HXs. The theoretical foundation for the cost optimization of a polymer microchannel HX is provided, and outputs are plotted in order to provide guidelines for designers to perform HX optimizations. These plots are used in two case studies: (1) …

Electric-Field Assisted Manipulation And Self-Assembly Of Particle Suspensions, Edison Chijioke Amah

Dissertations

The aim of this dissertation is to model the processes by which particles suspended in liquids and at liquid surfaces self-assemble when they are subjected to uniform and non-uniform electric fields. To understand the role of electric forces, three related problems were studied numerically and experimentally.

In the first problem, particles are assumed to be suspended inside a liquid and a nonuniform electric field is applied using electrodes mounted in the domain walls which causes positively polarized particles to collect in the regions where the electric field intensity is locally maximal and the negatively polarized particles collect in the regions …

A Methodological Framework For Quantifying Impacts Of Truck Traffic On Regional Network With Implications To Transport Policy, Chaitanya Narendra Pathak

Dissertations

Increased global trade has promoted the importance of shipping industry and the introduction of mega-ships has created an opportunity to be more cost-effective. Because of this, the expected change in freight transportation influences the operating regimes and schedules at the port terminals. Trucks being the predominant mode of transportation used to carry the freight transport, there is a growing concern about the impact of trucks in the region. The problems are further expected to grow as the improvements to resolve them are hindered by funding shortfalls. Public agencies are therefore involved in developing comprehensive state freight plans that outline immediate …

Combustion Of Nanocomposite Thermite Powders, Ian Monk

Dissertations

This work investigates combustion of nanocomposite thermite powders prepared by arrested reactive milling (ARM). The focus is on how ARM as a top-down approach to nano-thermite building generating fully-dense nanocomposite particles with dimensions of 1-100 µm affects the rates and mechanism of their combustion. A variety of thermites are milled using both aluminum and zirconium as fuels combined with several oxidizers (WoO₃, MoO₃, CuO, Fe₂O₃, and Bi₂O₃). The powders are ignited using both an electrostatic discharge (ESD) and a CO₂ laser beam.

A range of parameters vary …

Fabrication Of Mosfets On Ingaas With Al2o3, John Colern

Journal of the Microelectronic Engineering Conference

The goal of this project was to fabricate MOSFETs on InGaAs with an Al2O3 gate dielectric deposited with ALD. The initial structure of the device was planned out, the process was designed, and then each step of the process was characterized prior to the fabrication of the devices. The devices were fabricated, and then electrically tested. Each of the separate processes were shown to be repeatable and accurate. Errors with design rules in the mask lay- out led to shorting of the devices from source to drain, however the gate was found to be electrically isolated.

Monolayer Doping (Mld) For Ultra-Shallow Junction Mosfet Fabrication, Jenna Doran

Journal of the Microelectronic Engineering Conference

As devices continue to shrink following the trend of Moore's law, and non-planar devices such as Fin- FETs and 3D nanostructures become more common, ultra-shallow (sub-50 nm) junctions become more desirable. Semiconductor devices are traditionally doped using a combination of ion implantation or spin-on dopant and thermal diffusion techniques; however, these have limitations such as crystalline damage, use of hazardous chemicals, or glassy skin formation. Monolayer doping (MLD) provides a non-destructive and less hazardous method for doping the silicon surface. MLD creates a self-assembled monolayer of a dopant-containing compound followed by a rapid thermal anneal to form ultra-shallow junctions with …

Annealing Study Of Ald Deposited Ferroelectric Aluminum-Doped Hafnium Oxide, Joshua L. Eschle

Journal of the Microelectronic Engineering Conference

With the acquisition of a Savannah ALD tool at RIT, it is now possible to deposit ferroelectric Al-doped HfO2 (Al:HfO2) in the SMFL. Recipes for Al:HfO2 have been developed using tetrakis(dimethylamido)hafnium(IV) (TDMAHf) as a Hafnium precursor, and trimethyl aluminum (TMA) as an Aluminum precursor. Various percentages of Al in the Al:HfO2, controlled by the number of TMA cycles during the ALD deposition, were deposited in order to observe the effect of Al concentration on ferroelectricity. To determine the dependence of ferroelectricity on annealing conditions, samples underwent rapid thermal annealing steps at varying temperatures and times. The dependence of a top …

Design And Fabrication Of A Three-Axis Capacitive Accelerometer, Eddie Huang

Journal of the Microelectronic Engineering Conference

This paper focuses on the design and fabrication of a surface MEMS three-axis accelerometer with comb-drive fingers that measures acceleration up to 10G in the x/y-direction, and 5G in the z-direction on a single device using capacitve sensing. The fabrication process was performed in the Semiconductor and Microsystems Laboratory (SMFL), with a 7 level process flow to achieve the desired features. The accelerometer was designed to have a movable top electrode with sensing fingers attached to it to sense the change in capacitance the x/y-direction and a bottom electrode to sense the change in z-direction. The paper will focus on …

Vacuum Field Emission Devices With Integrated Cnts, Leo Kheyn-Kheyfets

Journal of the Microelectronic Engineering Conference

This research looks at the design and fabrication of sub 100-nm carbon nanotube-based vacuum field emission devices. The devices in this project are based in the Fowler-Nordheim emission of electrons, which allow the devices to hold radiation hardened capabilities due the absence of a semiconductor channel. On top of the radiation hardened capabilities of the Vacuum FETS, the emitter material, SWCNT (Single-Wall Carbon Nanotubes) themselves hold radiation hardened capabilities. SWCNT could also be the nanomaterial that replaces silicon in CMOS FETs (Field-Effect- Transistors). Through extensive preparation and testing, a field emission device based on carbon nanotube emitters with an effectiv …
