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 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.

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Hertzian Fracture in Ceramics and Ceramic Coatings" By Nesredin F. Kedir Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Weinong W. Chen ABSTRACT Advancement of gas turbine technology requires improvements in both cycle efficiency and overall performance. Much of the limitation, in this regard, emanates from the hot-section of the engine where a significant amount of thermal energy from combustion is wasted as exhaust. A promising approach to negate such loss considers substitution of standard Nickle-based superalloy components with advanced high-temperature ceramics. However, the inherent brittle nature of this material class has been shown to accentuate the effectiveness of impact damage by foreign debris. Hence, development of a robust semiempirical understanding of the process by which impact damage promotes failure becomes essential in accelerating ongoing technology transition efforts. A pervasive impact damage mechanism that is observed in both engine grade ceramics and coatings is Hertzian fracture. Subsequently, the underlying theory of Hertzian contact is presented with accompanying relations to observed quasi-static and dynamic fracture processes in glass, structural ceramics and ceramic coatings. Knowledge gaps in the dynamic loading regime are also discussed. Finally, progress on the development of an in-situ characterization method for observing impact induced fracture is offered.

Please consider attending the following this morning: MATERIALS ENGINEERING SEMINAR "Fe-Mn Alloys as Biodegradable Metallic Materials" By Duo Huang Purdue MSE Ph.D. Preliminary Exam Advisors: Professors David Johnson and Professor Matthew J. M. Krane ABSTRACT Biodegradable metallic materials are considered promising candidates to replace traditional permanent implants. Among all the metallic materials studied, Fe-Mn alloys show their potential to be a new type of biodegradable alloys. In this study, the design strategy of Fe-Mn alloys and the factors affecting Fe-Mn alloys' biodegradation behavior as well as mechanical properties are discussed. For alloy designing, adding less noble elements to form a solid solution and adding nobler elements to form intermetallic phases can both accelerate corrosion rates. The mechanical properties of Fe-Mn alloys are also discussed in the study. The effect of Mn concentration and intermetallic phases can modify alloys' mechanical properties. Considering all the factors discussed, a type of high manganese steel, Hadfield steel with 1.0 - 1.4 wt.% C and 10 - 14 wt.% Mn is proposed. Its unique properties make it possible to improve corrosion rate and mechanical properties at the meantime. Date: Friday, January 12, 2018 Time: 9:30 A.M. Place: ARMA 3115
