From: Inamdar, Amruta A Sent: Wednesday, October 04, 2017 12:25 PM Subject: Event for PhDs and postdocs: "Engineers in Industry" Hello: The CCO is organizing a presentation by Beverly Mentzer on how PhD students and postdocs can plan for a career in industry. Beverly retired as Vice President, ExxonMobil. She worked 33 years in both domestic & international engineering and managerial positions, and led engineers, geoscientists and onsite operations staff in US onshore and offshore oil & gas operations. She will discuss the skills needed by PhDs and postdocs if they want to succeed in industry, how best to utilize their technical skills, and which behaviors might inhibit their paths to advancement. The presentation will be followed by a Q&A session. Please consider posting the flyer in your office spaces, and encouraging your PhD students and postdocs to attend this event! Individuals in the Departments of Chemical, Materials, and Mechanical Engineering and Chemistry and those interested in working in the oil and gas industry will find this talk particularly helpful. Please direct questions about the event to me. Thank you!

Reminder for Yifan Zhang's Preliminary Exam, Thursday, Oct. 5, in ARMS 1021, at 9:30 a.m. "Deformation Twinning in Nanocrystalline Al"

Reminder for the following: MATERIALS ENGINEERING SEMINAR "Deformation Twinning in Nanocrystalline Al" By Yifan Zhang Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Xinghang Zhang ABSTRACT Deformation twinning is one of the primary deformation mechanisms in numerous metallic materials to accommodate shear strain and plastic deformation. In general, even under extreme deformation conditions, coarse-grained monolithic Al rarely deforms via deformation twinning because of its high stacking fault energy (104-142 mJ/m2). One practical pathway to facilitate deformation twinning is via grain refinement. Experimental studies and molecular dynamic simulations show several unique deformation twinning mechanisms in nanocrystalline (nc) Al with an average grain size of 100 nm or less. Furthermore, physical models have also been established to describe the nucleation and growth process of deformation twins. Date: Thursday, October 5, 2017 Time: 9:30 A.M. Place: ARMS 1021

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Real-time Spectral Birefringence Technique to Determine Polymer Morphology" By Megan Froshey Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Mukerrem Cakmak ABSTRACT It is difficult to predict complicated viscoelastic polymer responses when subjected to mechanical deformation. One way to measure microstructural changes during these processes is to pass white light through the sample and measure its retardation over time. The difference in chain orientation in axial directions affects how light interacts with the polymer sample, and converting this retardation to birefringence provides a way to quantify changes in polymer chain orientation. Historically, systems used to measure birefringence of polymers were very simple and led to various errors, such as human interpretation of results. Furthermore, they were not able to provide precise, quantitative results and never before were able to track polymer properties in real time. This presentation discusses the development of real-time spectral birefringence technique to quantify microstructure of polymers- a novel way to quickly and accurately measure changes in polymer structure while undergoing complicated processing steps, simulating those in industry. This technique can be applied to any situation in which polymers are subjected to thermal or mechanical stresses - such as film orientation, annealing, and drying - and has the goal of providing constitutive relationships between mechanical and optical properties of polymers to allow for prediction and control of polymer morphology. Important applications include biaxial film orientation, used in capacitors and food packaging, as well as novel technologies such as photovoltaics and wearable health sensors.
