Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Phase Change Materials as Temperature Regulators in Asphalt Pavement" By Daniela Betancourt Jimenez Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Carlos J. Martinez ABSTRACT Asphalt pavement constitute the building material for approximately 95% of the roads in the United States. However, due to the viscoelastic nature of the binder, the performance of the asphalt can be dramatically affected by extreme temperatures. The integration of phase change materials (PCMs) has been proven to be a feasible and effective way to regulate the temperature in other building materials and it's currently being investigated for asphalt applications. This report summarizes the main approaches studied for the incorporation of PCM systems in asphalt pavement materials and some of the challenges encountered in the process. It also proposes the use of a new technique for PCM microencapsulation that is believed will help overcome the problems associated with PCM encapsulation such as supercooling, low thermal conductivity and PCM leaking. It is believed that this new method will provide a viable solution to reduce asphalt distresses and delay the ice formation and snow accumulation during the winter season.

Reminder to attend the following: MATERIALS ENGINEERING SEMINAR "Alignment of Platelet-Grain Ceramic Particles in Shear and Elongational Fluid Flows" By Andrew Schlup Purdue MSE Ph.D. Preliminary Exam Advisors: Professor Rodney W. Trice and Professor Jeffrey P. Youngblood ABSTRACT Particle alignment in ceramics is a desirable microstructure feature due to the ability to control the properties of the sintered ceramic part, including mechanical, electrical, and even optical properties. These material property improvements originate from anisotropy that is a result of particle alignment. There are several ways to achieve particle alignment in a polycrystalline ceramic, with the most common method being the utilization of shear and elongational fluid flows. When high aspect-ratio ceramic particles (rods or platelets) are suspended in a fluid and that suspension is subjected to shear or elongational flows, the ceramic particles will preferentially orient due to the velocity profile gradient of the suspension. Thus, understanding the velocity profiles are critical for understanding how particle alignment occurs and how to control it. The velocity profiles of both shear and elongational flow will be discussed, along with their respective equations. Additionally, the orientation dynamics of particles in shear and elongational flow will be explored, as well as the governing equations that describe the rotation and subsequent orientation of high aspect-ratio particles in the different types of fluid flows. Finally, different processing methods found in the literature for achieving shear and elongational flow of ceramic-platelet/fluid suspensions will be discussed. These methods include tape-casting, co-extrusion, and biaxial extensional flow. The ways in which these methods are performed are crucial to understanding how the shear and/or elongational flow is manifested in the fluid, how the flow can be controlled, and the effectiveness of the method to align ceramic platelets.

Reminder to attend the following: MATERIALS ENGINEERING SEMINAR "The Mechanisms of Solute Effects on the Electrical Resistivity of Metal Alloys" By Mohammed Naziru Issahaq Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Kevin P. Trumble ABSTRACT Metallic electrical conductors usually lose their conductivity during material strengthening. Typical strengthening mechanisms for these metal conductors are grain size reduction, plastic deformation and solid solution strengthening. Among these mechanisms, the effect of impurity elements, in and out of solid solution is by far, the most potent mechanism for degrading electrical conductivity. The solute effect on conductivity however, varies with different solute atoms in solid solution. To determine how the electrical resistivity varies with increasing concentration of different solute atoms in a solvent, many theoretical models have been developed and tested against experimental data. It is found that, the resistivity does not exactly scale with the amount of lattice distortion due to atomic size differences between the solvent and solute atoms, but the interplay of several other factors including the distribution of the solute atoms in solution and the valence difference between the solvent and solute atoms. The direction of this review therefore, is to recap on the mechanisms that were thought to be the controlling factors of the solute effects on resistivity and what has now been found to constitute the working theory for the prediction of the impact of solute elements on the electrical resistivity of metals.
