Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Application of Cellulose Nanocrystals (CNCs) Coating on Polymers-A Pathway for Enhancement of Barrier Properties of Polymers" By Md Nuruddin Purdue MSE Ph.D. Preliminary Exam Advisors: Professor John Howarter and Professor Jeffrey Youngblood ABSTRACT Unlike metals and glass, polymers are permeable to gases and organic vapors to some extent. Polymer barrier properties influence the suitability of polymers for specific applications such as protective coatings, membrane separation processes, and packaging applications. For packaging applications, it is important for polymers to have good barrier properties to prevent the transportation of water, oxygen, carbon dioxide and organic vapor. In this study, a better understanding of the transportation mechanism of gases through polymers, and the factors affecting barrier properties were discussed. Cellulose nanocrystals (CNCs) are considered a potential nanomaterial for next-generation packaging products due to their biodegradability, non-petroleum based sources, high crystallinity, and mechanical properties. The objective was to utilize CNC coating (controlling the maximum alignment of CNCs) on polymers to enhance the gas barrier properties of polymers. Preliminary results showed that the alignment of CNCs coating enhanced the gas (O2, CO2 and water vapor) barrier property of the polymers. This suggests that aligned CNCs coatings on polymers have improved barrier properties over self-organized coatings for packaging applications. Date: Friday, January 26, 2018 Time: 10:30 A.M.

Please consider attending 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.

Please consider attending 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.

Please note the Seminar is tomorrow, Tuesday, Jan. 23, at 10:30 a.m., in ARMS 1103 MATERIALS ENGINEERING SEMINAR "Characterization of Surface Damage from Routine Disinfection" By Hyungyung Jo Purdue MSE Ph.D. Preliminary Exam Advisor: Professor John A. Howarter ABSTRACT In settings of the medical industry such as hospitals, the maintenance of hygienic surfaces is necessary in order to prevent contamination by a wide range of hospital associated infections (HAIs). The Centers for Disease Control and Prevention (CDC) recommends that high touch surfaces should be cleaned and disinfected on a routine basis, as often as several times per week to daily, in order to prevent the risk of pathogen transmission. Since hospital surfaces are disinfected with high frequency, the materials utilized for environmental surfaces and patient care equipment should have chemical resistance, as well as, must be able to withstand mechanical force. Thus, there are some test methods, such as Eastman-tritan and Sabic protocol, to aid medical equipment manufacturers in selecting materials for their device requirements. However, these tests focus on macro scale damage to prevent 'catastrophic failure'. Although the material largely still functions as intended, there is a potential risk of infection from the mechanically and chemically damaged surfaces, such as increased roughness of surface. Studies of the effects of surface roughness on the cleanability have found that roughened surfaces retained more bacteria after cleaning, due to the fact that bacteria could be trapped on the rough surface. Because there is no standard methodology to measure this impact, a number of relevant methodologies are needed to characterize microscale surface damage as a quantifiable physical or chemical change. To address this concern, this study will utilize various methods such as Fourier-transform infrared spectroscopy (FTIR), contact angle measurement, and atomic force microscopy (AFM) in order to characterize a material's potential for surface damage to a degree such that bacterial inhabitation is possible.
