Impurity effect on magnetism of nickel for under bump metallization via magnetron sputtering

Creator:: Ong, Justin B.
Abstract:: Nickel or nickel alloys are common materials used in under bump metallization (UBM) in flip chip technology. Nickel is used because of its slow reaction rate with tin-based solder at elevated temperatures. However, nickel is ferromagnetic at room temperature, hence cannot be easily deposited with magnetron sputtering. In this study,...

Investigation of solution-based processes for functional metal oxides : printing, nanostructures, and applications

Creator:: Han, Seung-Yeol
Abstract:: The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...

Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels

Creator:: Yang, Ping
Abstract:: Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are valuable as pollinators. Thus, candidate pesticides in development pipelines must be assessed for toxicity to bees. Leveraging a data set of 382 molecules with toxicity labels from honey bee exposure experiments, we...

Spherical Au Nanoparticle Interaction with Lipid Monolayers Probed with Sum Frequency Generation Spectroscopy

Creator:: Faase, Ryan A.
Abstract:: Nanoparticles have become more prevalent from their use in sunscreen to antimicrobial agents in socks. In light of these applications, gaining a fundamental understanding of how NPs interact with humans is crucial for their future. Specifically, how cells interact with NPs and what factors drive the modes of cellular uptake....
