The work for this thesis was done in conjunction to that of my capstone project, which focused on understanding the effects of powder re-use on products built via Direct Metal Laser Sintering (DMLS), a specific additive manufacturing (AM) technique where powder particles are sintered together to form final parts. Honeywell Aerospace helped support this research by providing materials and mentorship; this work will play a key role in their decision to implement DMLS and other AM methods on a larger scale. Whereas the capstone focuses on the technical details of constructing characterization equipment, analyzing data, and formulating a concluding recommendation ...

The semiconductor industry looks to constantly improve the efficiency of research and development in order to reduce costs and time to market. One such method was designed in order to decrease time spent inducing warpage in integrated circuits in an Intel research process. Intel’s Atom product line seeks to compete with ARM architecture by entering the mobile devices CPU market. Due to the fundamental differences between the Atom’s Bonnell architecture and the ARM architecture, the Intel Atom product line must utilize such improved research and development methods. Until power consumption is drastically lowered while maintaining processing speed, the Atom product ...

The characteristics possessed by undergraduates who have enjoyed success in an intern position are defined. Through an interview process, four traits were identified: multitasking, strong team work understanding, an inquisitive nature, and application of a cross-disciplinary mindset. An exposition of how these four traits are employed to ensure success in an internship setting is then given. Finally, a personal account of a project with Intel is expounded upon. This project addressed the unoptimized characterization test time of an Intel package quality control process. It improved throughput by developing a parallel testing method by increasing package carrier capacity and utilizing simultaneous ...

The financial feasibility of NextPotential’s X-doped photocatalyst is uncertain, the outcome depends on how much the material cost becomes reduced due to mass production techniques. If carbon taxes continue on the current trend the photocatalyst is highly likely to become financially feasible. Without carbon taxes, it is still likely the photocatalyst will achieve economical feasibility. The land area required by the photocatalyst is a feasible size. The minimal environmental downsides are that more land will be used and water will be used, but both of these are minimal compared to the benefit of eliminating carbon emissions.

The transition to lead-free solder in the electronics industry has benefited the environment in many ways. However, with new materials systems comes new materials issues. During the processing of copper pads, a protective surface treatment is needed to prevent the copper from oxidizing. Characterizing the copper oxidation underneath the surface treatment is challenging but necessary for product reliability and failure analysis. Currently, FIB-SEM, which is time-consuming and expensive, is what is used to understand and analyze the surface treatment-copper oxide(s)-copper system. This project’s goals were to determine a characterization methodology that cuts both characterization time and cost in half for ...

Autism Spectrum Disorder is a disorder that makes learning, socializing and daily living much more challenging for affected children and adults because of their atypical behaviors. A few examples of these behaviors are repetitive movements, impulsive actions, inability to communicate in a social setting, and many more. There is a stigma behind autism that is caused by those who are not well informed on the disorder. These people lack information, and in the past, it was assumed that the disorder is caused by “bad parenting.” The parents are then afraid of social shame brought upon them by their child and ...

A novel approach, the Invariant Based Theory of Composites and the “Trace” method it proposes, has the potential to reduce aerospace composite development times and costs by over 30% thus reinvigorating the development process and encouraging composite technology growth. The “trace” method takes advantage of inherent stiffness properties of laminates, specifically carbon fiber, to make predictions of material properties used to derive design allowables. The advantages of the “trace” theory may not necessarily be specific to the aerospace industry, however many automotive manufacturers are facing environmental, social and political pressure to increase the gas mileage in their vehicles and reduce ...

The goal of the paper was to examine the fatigue mechanisms of polymers and silicone based elastomers. The mechanisms of fatigue due to crazing: the alignment of polymer chains to the stress axis, and shear banding: the localized orientation of the polymer by the shear stresses from two planes, were discussed in depth in this paper. Crazing only occurs in tensile stress, is initiated on the surface of the material, and only occurs in brittle polymers. Crazing also accounts for a 40-60% decrease in density, causing localized weakening of the material and a concentration in stress. This is due to ...

This research examines the presentation of ASD in fictional children’s literature. The goal is to use the research collected to determine what symptoms of ASD are receiving coverage versus what is not being covered but needs to be in a children’s book about ASD. This was accomplished by first consulting background literature on ASD before examining 40 children’s books about characters on the spectrum. It was found that girls on the spectrum received less coverage than boys did, and that most books conformed to one of two types: looking at ASD through the eyes of a neurotypical child and looking ...

In injection molded plastic parts, knit lines occur where opposing streams of material fuse together while the mold cavity fills. When parts with knit lines experience external loading, the knit lines cause areas of mechanical weakness. This weakness is especially drastic in fiber-reinforced polymers due to an unfavorable orientation of fibers at the knit line. A possible way to reduce the impact of knit lines is to incorporate overflow tabs into the mold design. An overflow tab is a chamber attached to the mold cavity that provides an extra space for the end of material flow to occur. Research shows ...

Barrett, the Honors College accepts high performing, academically engaged students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project, supervised and defended in front of a faculty committee. The thesis or creative project allows students to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is a student’s opportunity to explore areas of academic interest with greater intensity than is possible in a single course. It is also an opportunity to engage with professors, nationally recognized in their fields and specifically interested and committed to working with honors students. This work provides tangible evidence of a student’s research, writing and creative skills to graduate schools and/or prospective employers.
