The role of material properties in an ISBM process to manufacture polypropylene bottles from virgin and PCR resins

Creator:: Chen, Cheng-Ting
Abstract:: Post-Consumer Recycled (PCR) resin grades have been successfully incorporated into plastic ink supply cartridges, with 80% of cartridge products containing 45% to 70% recycled polyethylene terephthalate (rPET). With this tremendously successful experience, incorporation of recycled polypropylene (rPP) into Injection Stretch Blow Molding (ISBM) bottles has been attempted to increase sustainability...

Microfluidic Investigations of Capillary Flow and Surface Phenomena in Porous Polymeric Media for 3D Printing

Creator:: Donovan, Katrina J.
Abstract:: The advent of 3D Printing has invigorated research into metamaterials, synthetic composite material that produce properties generally not found in natural materials, requiring further studies into understanding the fundamental properties of these materials. This dissertation proposes a novel imaging technique to investigate the surface interactions occurring in an unsaturated packed...

Hydraulic Jump Dynamics for Water Jet Impingement on Vertically Oriented Rotating Surfaces

Creator:: Adiga, Prajwal P.
Abstract:: Silicon wafer cleaning is a ubiquitous unit operation in the semiconductor industry to remove excess material or nanoparticle impurities to obtain perfectly smooth and clean wafer surfaces. Extensive research has already been completed to understand the physics behind hydraulic jumps observed due to balance of forces when a coherent Newtonian...

Development of a Smartphone App to Easily Measure Extensional Viscosity

Creator:: Swift, Aleesha M.
Abstract:: The measurement of extensional viscosity is important in many chemical, biomedical, agricultural, and engineering applications. The determination of extensional viscosity is generally difficult, expensive, and inaccessible outside of research labs. The development of a smartphone application (app) that could use a phone’s high-speed camera to measure this parameter could open...

Development of a Medicinal Infused Hydrogel Patch for the Treatment of Burns and Diabetic Ulcers

Creator:: Griffiths, Abigail E.
Abstract:: Metamix is a mixture of botanical compounds that promote healing and prevent infection for burns and diabetic ulcers. In this thesis, metamix was incorporated into 1.75 weight percent gellan gum hydrogels as a drug delivery method for burned skin. The ideal concentration of metamix was 25% by solution volume for...

Dynamic Surface Tension on the Microsecond Timescale : Thermal Inkjet Printing Applications

Creator:: Wilson, Madeline
Abstract:: This project explores the relationship between microsecond-timescale dynamic surface tension (DST) and measurable thermal inkjet printing parameters. Dynamic surface tension affects many aspects of printing, including printing speed and ink drop shape. In addition to this, DST is a physical input parameter for HP’s in-house computational fluid dynamics program. HP...

Stimulated jet break-up for production of uniform size microgel beads from cross linked sodium alginate solutions

Creator:: Gill, Hardeepak (Happy) Singh
Abstract:: The goal of this thesis was to develop a process of producing small monodisperse alginate gel beads. The phenomenon of controlled jet break-up of alginate solution jet with assisted vibration was used to form uniform sodium alginate droplets which were subsequently crosslinked with divalent calcium ion to form gel beads....

Studies of polystyrene (PS) high density polyethylene (HDPE) and PS/HDPE/wood composites from an extrusion process : mechanical properties, rheological characterization and morphology

Creator:: Xu, Bin
Abstract:: The global motivation for this work comes from the desire to fabricate "plastic lumber" with improved mechanical properties (particularly creep resistance) from recycled plastics and wood composites. The present studies have utilized "virgin plastics" of polystyrene (PS), an amorphous, stiff material that exhibits brittle fracture, and high density polyethylene (HDPE),...
