06 Nov '19

Hello MSE Researchers, Lab access to all Armstrong lab spaces as well as Effron Student Lounge and the computer lab have been restored with exception to lab access request forms received in the past week or so. If you submitted a form prior to last week and you are still unable to swipe into that lab space, please let me know.

Seminar Reminder for Juncheng Liu's Prelim Exam. Seminar, Thursday, November 7, at 8:30 a.m., in ARMS B071. " Van der Waals Epitaxy Growth of Oxides on Muscovite Mica"
by Son, Rosemary E 06 Nov '19

06 Nov '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Van der Waals Epitaxy Growth of Oxides on Muscovite Mica" By Juncheng Liu Purdue MSE Preliminary Exam Advisor: Professor Haiyan Wang ABSTRACT Van der Waals epitaxy (vdWE) growth has piqued a lot of interest as it can allow systems withlarge lattice mismatch to grow epitaxially due to weak van der Waals interaction at the interface of overlayer and substrate. Muscovite mica has a quasi-2D structure without dangling bonds at the surface which can be a good platform for vdWE. Oxide thin films and different nanostructures have been successfully fabricated on muscovite mica. This review uses some examples to discuss the unique features and growth mechanisms of vdWE of oxides on muscovite mica, together with the remaining challenges of this research field. Key words: Van der Waals, Mica, Oxides, Growth mechanisms Date: Thursday, November 7, 2019 Time: 8:30 A.M. Place: ARMS B071

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "On the Continuous Production of Electric-Field Structured Piezoelectric Composite Films as Ultrasonic Transducers" By Jesse C. Grant Purdue MSE Preliminary Exam Advisor: Professor Mukerrem Cakmak ABSTRACT Piezoelectric materials enjoy a broad set of applications as transducers by converting mechanical energy to electrical energy. While piezoceramics are inherently brittle and opaque, thermosetting polymers can be mechanically tough, flexible, and transparent. Properties of both can be preserved in an anisotropic composite, where piezoelectric particles are aligned into chain-like structures running through the thickness of the material, termed a quasi-1-3 composite. This is achieved through electric-field structuring, a facile process that decreases the amount of filler material required via anisotropy, is scalable, and is compatible with continuous production. Improving the performance of composite material relies on tuning processing conditions due to the structure-property relationship and material properties of the constituents. In taking a wholistic approach to fabricating ultrasonic transducers in a roll-to-roll manner, benefits are promised for applications such as medical imaging, structural health monitoring, and hydrophones. Keywords: piezoelectricity, anisotropy, quasi-1-3 composite, electric-field structuring, ultrasonic transducer Date: Wednesday, November 6, 2019 Time: 1:00 P. M. Place: HAMP 2118

Seminar Notice for Alejandro Figueroa's Preliminary Exam, Friday Nov. 15, at 8:00 a.m., in ARMS 1021 "Irradiation Induced Grain Refinement in Low Temperature U-Mo Metallic Fuels"
by Son, Rosemary E 04 Nov '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Irradiation Induced Grain Refinement in Low Temperature U-Mo Metallic Fuels" By Alejandro L. Figueroa Purdue MSE Preliminary Exam Advisor: Professor Maria A. Okuniewski ABSTRACT Uranium molybdenum based fuels are currently being qualified as a replacement for high enrichment fuels, in high performance research and test reactors, as a global threat reduction effort. Irradiation induced grain refinement is currently being investigated in low operating temperature (<0.4Tm) nuclear fuels due to its association to an increase in swelling rates. Uranium molybdenum alloys are of interest due to their accumulation of fission gasses into an ordered nano-bubble superlattice. The superlattice has been observed to suppress the formation of the defect structures typically associated with irradiation induced grain refinement. This behavior limits the ability to correlate the observed mechanisms with historical data. Understanding the underlying mechanisms of irradiation induced grain refinement will aid in fuel performance by tailoring fuel design to suppress the transformation, and accounting for the formation in operating codes. This review discusses the current efforts in characterizing the transformation mechanism, its effect on the microstructure, and modelling of the phenomenon.

FW: Three CCO workshops in November
by Son, Rosemary E 04 Nov '19

04 Nov '19

Hello, all The first two workshops are online (so, hopefully distance learners can also attend). The third workshop will be a presentation and Q&A by Bev and Dr. Ray Mentzer (both retired senior execs. from Exxon Mobil) on the challenges faced by advanced degree holders (PhDs, mostly) when they first enter industry positions. Bev and Ray provide guidelines and strategies to maximize your chances of success in industry. Though all are welcome to attend, this event will be most applicable to engineers and chemical scientists. Monday, Nov. 4: Resumes Time: 12:00 p.m. Location: online (Webex) Register here: https://tinyurl.com/y3ktcug7 Monday, Nov. 11: Cover letters Time: 12:00 p.m. Location: online (Webex) Register here: https://tinyurl.com/yxhpotuo Monday, Nov. 11: Transitioning to Industry Time: 5:00 p.m. Location: WALC 3090 RSVP not required; room seats 60.
