Abrasive Wear Assessment of X70 Steel and Polyurethane Coupons on a Modified Dry/Sand Rubber Wheel ApparatusDownload
An experimental study was conducted to assess the scratching abrasion in dry and wet environments on X-70 steel and five different types of titanium carbide particulate polyurethane composites (PU). A testing apparatus was constructed based on the dry sand rubber wheel test method standardized by...
Shape memory polymers (SMPs) can be used in many critical applications, including biomedical and aerospace fields, due to their ability to recover their original/permanent shape from a deformed/temporary shape upon application of a stimulus. SMPs are subjected to bending in a large number of...
Concentration and Mixing Effects on the Production of Amine Hydrochloride Salts in a Confined Impinging Jet ReactorDownload
A Confined Impinging Jet Reactor (CIJR) was used to react 4, 4’-methylene dianiline (MDA) with hydrogen chloride (HCl) in order to study formation of the aminehydrochloride (AHC) salts, unwelcome byproducts in the manufacture of polyurethanes. The effects of several processing variables (local...
Polyurethane has excellent wear resistance and is an effective protective liner against erosion caused by the impact of solid particles. However, similar to most polymeric materials, polyurethane has low thermal and electrical conductivity, and this limits its applicability for use in...
The use of polymers in applications such as electronic packaging, heat exchangers, and thermal pastes is limited by their inability to dissipate accumulated heat effectively. Nano-scale filler modifiers may be used to improve the transport of thermal energy through polymer materials. Studies of...
An alternative method of manipulating fragile MEMS devices during fabrication has been developed. A specialized manual or robotic end effector utilizing a gecko inspired adhesive can replace the slow and costly manual tweezers used by the MEMS foundry Micralyne Inc. Improving the adhesive...
This thesis first describes the development of novel analytical methods for use in lipid transformations. It continues with the synthesis of vegetable oil-based polyols with high hydroxyl value (OHV) and low viscosity, an example of a lipid transformation. Vegetable oils are amenable to...
