Seminar Reminder for Sung Ho Yook's Preliminary Exam, Tuesday, Nov. 7, at 1:00 p.m., in HAMP 2107. "Electric-Field Alignment of Polymer Blends with Dispersed Nanoparticles for Mesoporous Reactive Membranes"
by Son, Rosemary E 06 Nov '17

06 Nov '17

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Electric-Field Alignment of Polymer Blends with Dispersed Nanoparticles for Mesoporous Reactive Membranes" By Sung Ho Yook Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Mukerrem Cakmak ABSTRACT Polymer blends of two immiscible polymers show unique properties due to the combination of mechanical, electronical, and optical properties of two different materials. The morphologies of polymer blends can be droplets or bicontinuous morphologies according to the production conditions. The 3D-bicontinuous morphology are particularly interesting among the morphologies, because they can be practically applied to mesoporous polymer membranes or heterojunction photovoltaic cells. However, the bicontinuous morphologies are not stable because each polymer phase tends to reduce interfacial area between two polymers by coarsening small domains to large domains. One of the ways to stabilize bicontinuous morphologies is to add nanoparticles. Nanoparticles located either in one polymer phase or at interface can retard the coarsening process. Meanwhile, the morphology of polymer blends with nanoparticles also can be influenced by the electric fields. Nanoparticles and polymer phases can be aligned parallel to the electric field direction if two polymers and nanoparticles show the difference in dielectric constants. Therefore, the electric field effect on nanoparticles stabilized morphologies in a polymer blend must be interesting topic. In this presentation, nanoparticle stabilized polymer blends and the electric field effects on them will be discussed. The turning materials properties by aligning polymer blends with dispersed nanoparticles in the electric field also will be suggested. Date: Tuesday, November 7, 2017 Time: 1:00 P.M.

Seminar Reminder for Xiaohui Xu's Preliminary Exam, Tomorrow, Tuesday, Nov. 7, 10:00 a.m., in PHY 110. "Investigation of Laser-Matter Interaction Utilizing Advanced Transmission Electron Microscopy"

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Investigation of Laser-Matter Interaction Utilizing Advanced Transmission Electron Microscopy" By Xiaohui Xu Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Volkan Ortalan ABSTRACT Laser-matter interactions have been extensively investigated in the past few decades. Specifically, pulsed laser owns unique properties compared with continuous wave laser, which makes it popular in many fields. The effect of pulsed laser on materials is related to the nature of the material and width of laser pulse duration. By carefully adjusting laser pulse width and selecting the materials, laser synthesis can be achieved either by a bottom-up or a top-down way. Laser welding of plasmonic materials is another significant research area, whose mechanisms have not been fully understood. With the advent of the ultrafast transmission electron microscopy (UTEM), the in-situ investigation of laser-matter interactions becomes possible with both high spatial and temporal resolutions. Therefore, it is a unique instrument to explore possible laser synthesis routes and to obtain fundamental insights into the mechanisms of laser-matter interactions in general. Keywords: pulsed lasers, ultrafast transmission electron microscopy, laser-matter interactions, laser synthesis, plasmonic nanostructures. Date: Tuesday, November 7, 2017 Time: 10:00 A.M.

Seminar Notice for Daniela Betancourt Jimenez's Preliminary Exam, Monday, Nov. 13, at 1:30, in ARMS B071, "Phase Change Materials as Temperature Regulators in Asphalt Pavement"
by Son, Rosemary E 06 Nov '17

06 Nov '17

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. Date: Monday, November 13, 2017 Time: 1:30 P.M. Place: ARMS B071

Hello, all I'm writing to request you to advertise this opportunity within your departments. Thank you. Due to high demand (many, many more students & postdocs showed up than there was room for!), we're offering a repeat of Beverly Mentzer's talk on "Researchers in Industry." Beverly has graciously agreed to repeat her interactive presentation on how PhDs could use their technical and scientific skills more effectively, and discuss strategies to maximize success within an industry setting as well as pitfalls and behaviors that may inhibit researchers' success in industry. Though open to all grad students and postdocs, the presentation is most applicable to individuals in science and engineering departments at Purdue. Date: Nov. 9 (Thu.) Location: WALC B066 Time: 5:30 PM to 6:30 PM No RSVPs needed. Please direct other questions about this event to me.

Seminar Reminder for Yifan Zhang's Preliminary Exam, Nov. 6, in B071, at 11:30 a.m. "Deformation Twinning in Nanocrystalline Al"
by Son, Rosemary E 03 Nov '17

03 Nov '17

Please consider attending 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 major deformation mechanisms in metallic materials to accommodate shear strain and plastic deformation. As widely accepted, Al rarely deforms via deformation twinning because of its high stacking fault energy (142-165 mJ/m2). Only under certain conditions, such as cryogenic temperature, extremely high strain rate, addition of solutes as well as nanoscale grain size, can deformation twins form in Al. Experimental studies and molecular dynamic simulations have revealed the important roles of grain boundaries on the deformation twinning in nanocrystalline (NC)Al. Several GB-mediated twinning mechanisms will be discussed in this work. Date: Monday, November 6, 2017 Time: 11:30 A.M. Place: ARMS B071

by Son, Rosemary E 03 Nov '17

03 Nov '17

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Mechano Optical Behaviors of Nanocomposite Hydrogels" By Zeynep Mutlu Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Mukerrem Cakmak ABSTRACT Hydrogels are made of three-dimensional polymer networks which have high water content. There are various kind of applications of hydrogels such as a superabsorbent material, scaffold for tissue engineering, wound care material, and contact lens. Carbon-based, polymeric, ceramic, and metallic nanoparticles can be integrated within the hydrogel networks to obtain nanocomposites with superior. There is a plethora of work done on mechanical behaviors of nanocomposite hydrogels; however, a real-time mechano-optical behavior that can reveal important information regarding the molecular orientation of polymer chains and clay nanoparticles during large deformation is still lacking. This presentation discusses the real-time mechano-optical study on strain-induced optical anisotropy of nanocomposite hydrogels synthesized from DMA and Laponite XLG nano-clay. Details of the microstructural changes and chain orientation during deformation are also discussed. Date: Monday, November 6, 2017 Time: 9:30 A.M. Place: HAMP 2108
