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...

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...

Monitoring redox conditions with redox indicators during microbial reductive dechlorination in microcosms and bioaugmented columns

Creator:: Ruiz-Haas, Peter A.
Abstract:: New methods, sensors, and devices based on redox indicators were developed to monitor redox conditions in anoxic and anaerobic laboratory systems and the subsurface environment. The primary application was monitoring redox conditions during the dechlorination of tetrachioroethene (PCE) to ethene (ETH) in packed columns and microcosm bottles containing an enriched...

Process-based modeling for cradle-to-gate energy and carbon footprint reduction in product design

Creator:: Alsaffar, Ahmed J.
Abstract:: Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...

Development and evaluation of a new formaldehyde-free wood adhesive from renewable materials for making interior plywood

Creator:: Jang, Yonghwan
Abstract:: Synthetic adhesives, such as phenol-formaldehyde (PF) resins and urea-formaldehyde (UF) resins, have dominated the wood adhesive market since they were introduced in the wood products industry. Formaldehyde, as a key component in the manufacturing of PF and UF resins, has been classified as a known human carcinogen by the International...

Development of microchannel arrays in aluminides

Creator:: Hasan, Hadi
Abstract:: Micro Energy and Chemical Systems (MECS) devices enable at least two areas of benefit due to the accelerated heat and mass transfer that can be accomplished in microchannels. First, MECS devices enable process intensification; the ability to reduce the volume of space needed to implement systems of thermal and chemical...

Non-destructive evaluation of veneer using optical scanning and ultrasonic stress wave analysis systems

Creator:: DeVallance, David B.
Abstract:: Non-destructive commercial ultrasonic grading provides laminated veneer lumber (LVL) manufacturers a means for sorting veneer based on average ultrasonic propagation time (UPT) and/or average dynamic modulus of elasticity (MOEd). While this may provide reliable estimations of modulus of elasticity (MOE), little is known about the influence of veneer defects on...

Mechanistic aspects of fracture and fatigue in resin based dental restorative composites

Creator:: Shah, Minalben B.
Abstract:: For resin based dental restorative composites, one of the major challenges is to optimize the balance between mechanical and optical properties. Although fracture is the second leading cause of dental restorative failures, very limited mechanistic understanding exists on a microscopic level. In the present study, the fracture properties and mechanisms...

An internal convective heating technique for diffusion bonding highly parallel microchannel architectures

Creator:: Bose, Sumantra
Abstract:: Diffusion bonding cycle times can be a large cost factor in the production of metal microchannel devices. The challenge is to significantly minimize this cost by reducing the bonding cycle time through rapid and uniform heating and cooling within the bonding process. Heating rates in diffusion bonding processes are typically...
