Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

Micromixer assisted continuous flow synthesis of nanoparticles of binary compounds and their application

Creator:: Palanisamy, Barath
Abstract:: In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...

Fluidic and thermal modeling for the high production rate synthesis of high quality nanoparticles

Creator:: Peterson, Daniel Alan
Abstract:: Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...

Synthesis of colloidal metal oxide nanocrystals and nanostructured surfaces using a continuous flow microreactor system and their applications in two-phase boiling heat transfer

Creator:: Choi, Chang-Ho
Abstract:: Metal oxide nanocrystals have attracted significant interests due to their unique chemical, physical, and electrical properties which depend on their size and structure. In this study, a continuous flow microreactor system was employed to synthesize metal oxide nanocrystals in aqueous solution. Assembly of nanocrystals is considered one of the most...

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...

Production of biohydrodeoxygenated diesel in a novel microscale reactor : Experiments and modeling

Creator:: Atadana, Frederick Williams
Abstract:: Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing...

Performances and kinetic studies of hydrotreating of bio-oils in microreactor

Creator:: Attanatho, Lalita
Abstract:: Hydrotreating reaction of vegetable oil is an alternative method for the production of renewable biodiesel fuel. This reaction involves conversion of triglycerides into normal alkanes, leads to a deoxygenated and stable product, which is fully compatible with petroleum derived diesel fuel. The hydrotreating process uses hydrogen to remove oxygen from...

An investigation of multiphase flow in complex microchannel geometries for hemodialysis systems using residence time distribution analysis

Creator:: Coblyn, Matthew Y.
Abstract:: There are approximately 2.2 million cases of End-stage Renal Disease (ESRD) worldwide and current hemodialysis treatment is costly and ultimately insufficient compared to kidney transplantation. There is a strong need to arrive at a better solution for treating ESRD. Microchannel-based hemodialysis is one proposed option, already shown to have improved...

Synthesis, characterization and deposition of dendrimers using a continuous flow microreactor

Creator:: Liu, Shuhong
Abstract:: Dendrimers are nanoscale macromolecules that have highly branched, core-shell structures. Higher generation dendrimers have close-packed peripheral functional groups and a hollow interior. The chemistry of the core and the terminal functionalities can be tailored according to the specific application. These structural characteristics provide room for the design of dendrimers to...
