Immobilization of Methylosinus trichosporium OB3b in a Biolamina Plate Reactor for the Oxidation of Methane to Methanol

O Criador:: Fuchs, Brian K.
Abstract:: Methane is a flammable gas that is the main component of natural gas. It is a highly potent greenhouse gas, and accounts for about 20% of greenhouse gas emissions. Methane is routinely flared in many industrial processes without harnessing any of its energy. The environmental impact and wasted energy potential...

Laminate mixing in microscale fractal-like merging channel networks

O Criador:: Enfield, Kent E.
Abstract:: A two-dimensional model was developed to predict concentration profiles from passive, laminar mixing of concentration layers formed in a fractal-like merging channel network. Both flat and parabolic velocity profiles were used in the model. A physical experiment was used to confirm the results of the model. Concentration profiles were acquired...

Flow induced mixing in high aspect ratio microchannels

O Criador:: Siripoorikan, Bunchong
Abstract:: Micro-fluid mixing is an important aspect of many of the various micro-fluidic systems used in biochemical production, biomedical industries, micro-energy systems and some electronic devices. Typically, because of size constraints and laminar flow conditions, different fluids may only have the opportunity to mix by diffusion, which is extremely rate limited....

Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

O Criador:: Pluess, Christoph
Abstract:: Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

An experimental study of co-flow ammonia-water desorption in an oil-heated, microscale, fractal-like branching heat exchanger

O Criador:: Mouchka, Gregory A.
Abstract:: An experimental study was performed in which an ammonia-water solution was desorbed within a branching fractal-like microchannel array. The solution entered in the center of a disk, and flowed out radially until discharging in to a gravity-driven separation chamber. Heat was added to the ammonia-water through a thin wall, above...

A study of high shear multiphase flow in a microchannel

O Criador:: Morse, Daniel R.
Abstract:: Microscale fluid processes are an increasingly important subgroup of fluid mechanics. Applications for heat transfer and micro-electro-mechanical devices use flows on the scale of less than one hundred microns. This study is part of a larger work in which a multiphase, high shear environment is studied in a microchannel that...

Preparation of semiconductor nanoparticle solutions using microreaction technology

O Criador:: Kroon, Joan M.
Abstract:: Nanoparticles, materials on a 10⁻⁹ meter size scale, are finding applications in a variety of areas including catalysts, fuel and solar cells, biological labeling. electronics and optoelectronic devices. Semiconductor nanoparticles are of particular interest because of their size tunable properties resulting from quantum confinement effects. Mass productions of monodisperse semiconductor...

Flow boiling of lithium bromide-water solution in microchannels, with application to desorption

O Criador:: Fackrell, Kurt
Abstract:: Recent studies of flow boiling within microchannels have shown high heat fluxes, leading to successful design and testing of compact heat exchangers, cooling systems for electronics and other high efficiency, miniature components. An experimental study of flow boiling of a concentrated salt solution in microchannels is presented. Experiments examined flow...

Microlamination based on surface mount technology for the economical production of microchannel arrays

O Criador:: Sharma, Nitin
Abstract:: Micro Energy and Chemical Systems (MIECS) are multi-scale microsystems, which rely on embedded nano and micro-scale features to process bulk amounts of fluid in applications ranging from man-portable heat pumps, distributed fuel reforming and insitu waste remediation. Microlamination is a well-known process architecture for fabricating the highly parallel, high aspect...

Micro-bubble dynamics in two-phase flow through a micro-channel

O Criador:: Shepard, Thomas G.
Abstract:: An experimental investigation into the behavior of micro-bubbles flowing through a micro-channel has been conducted. Experiments were performed within a rectangular micro-channel with dimensions of 5 cm x 13.2 mm x l30 jim. Bubbles were generated in an electrolyte solution by electrolysis at the lower channel wall near the inlet....
