From electrophoresis to dielectrophoresis: designing, fabricating, and evaluating an electroformed ratchet type microfluidic dielectrophoresis device

Creator:: Gonzalez, Carlos F.
Abstract:: Dielectrophoresis (DEP) is a separation method in which a non-uniform electric field is used to induce a dipole moment in a suspended particle. If the polarization of the particle is greater than that of the suspending medium, the particle will move towards the region of higher field strength (positive DEP);...

Mixed reactant single chamber fuel cell, using products generated from the electrolysis of an aqueous electrolyte

Creator:: Jost, William C.
Abstract:: A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell...

Applications of the thermal wave technique in liquid thermal conductivity measurements and flow field diagnostics

Creator:: Wang, Zhefu
Abstract:: The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...

Fabrication and characterization of nanostructured surfaces for enhanced heat transfer

Creator:: Choi, Changho
Abstract:: This objective of this study is to investigate the capability of nanostructured surfaces on dissipating heat flux by performing pool boiling and convective flow boiling. The generation of ultra-high heat flux from high performance electric devices has motivated a number of investigations related to advanced heat transfer especially in two-phase...

Mass transfer of urea, creatinine and vitamin B-12 in a microchannel based membrane separation unit

Creator:: Warner-Tuhy, Alana
Abstract:: Micro energy and chemical systems (MECS) are microfluidic systems where energy and chemical processes can be intensified by decreasing the characteristic length. This project focused on bulk fluid processing using MECS technology to intensify the mass transport of a dialyzer. The objective of this project was to design a model...

Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

Creator:: Jin, Hyung Dae
Abstract:: Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...

Machining and toxicological performance of a zinc oxide metalworking nanofluid

Creator:: Sahakian, Misha
Abstract:: Lower production costs are a common goal of many manufacturers as part of their continuous improvement strategies. A large portion of production costs for manufacturers is the machining of metals to form components. Metal machining is accompanied by friction and heat which is dealt with using metalworking fluids such as...

Continuous synthesis of metal-organic frameworks under high pressure

Creator:: Li, Yong J.
Abstract:: Metal Organic Framework (MOF) materials, consisting of metal ions with organic linkers, have a functional cavity structure which can be utilized in applications such as catalyst, micro sensing, and gas absorption. Due to MOF materials' selective gas adsorption property, interest in MOF materials has intensified in the last few years,...

Component placement sequence optimization in printed circuit board assembly using genetic algorithms

Creator:: Hardas, Chinmaya S.
Abstract:: Over the last two decades, the assembly of printed circuit boards (PCB) has generated a huge amount of industrial activity. One of the major developments in PCB assembly was introduction of surface mount technology (SMT). SMT has displaced through-hole technology as a primary means of assembling PCB over the last...

Quantifying nisin adsorption behavior at pendant polyethylene oxide brush layers

Creator:: Dill, Justen K.
Abstract:: A more quantitative understanding of peptide loading and release from polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. The antimicrobial peptide nisin shows potent activity against Gram-positive bacteria including the most prevalent implant-associated pathogens, its mechanism of action minimizes the...
