ARMS 2136 Buehler Abrasive Saw
by Pauly, Darren A 14 Oct '19

14 Oct '19

All, There is a problem with the drain filters in these machines becoming clogged after a short period of use; a problem that is becoming more and more frequent. This problem is due to students cutting samples with tape and/or cotton balls/other material attached to the samples. Before cutting these samples ALL TAPE/COTTON/OTHER MATERIAL attached needs to be removed. NO exceptions. The debris created by the tape/cotton/etc completely clogs the drain filter, which in turn causes the recirculating water to back up and spill out of the drain hose onto the floor instead of going back into the reservoir tank as designed. This leads to a big mess being created in a short amount of time; a mess that the student using the machine is responsible for cleaning up. If this problem persists the machine in question will be locked out until further notice. If you have any questions/concerns/etc please feel free to contact me. Thank you very much for your cooperation with this matter. Sincerely, Darren Darren Pauly Laboratory Technician VIII School of Materials Engineering Purdue University (765) 494-7703

Good afternoon, Please take a few minutes of your time to fill out the attached 'Emergency Contact Form'. Once completed, please submit the digital form to me via e-mail (akublanc(a)purdue.edu<mailto:akublanc@purdue.edu>) or a printed copy at the front desk. I understand that a similar form circulated this past spring, but our aim is to ensure our files are accurate and up-to-date in case of emergencies. Feel free to send any questions my way and thank you all for your help!

Seminar Reminder for Nicholas Richter Oct. 10, at 8:30 a.m., in ARMS 3109. " Micropillar Compression Studies of Deformation Behavior in Nanostructured FCC Metals"
by Son, Rosemary E 09 Oct '19

09 Oct '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Micropillar Compression Studies of Deformation Behavior in Nanostructured FCC Metals" By Nicholas A. Richter Purdue MSE Preliminary Exam Advisor: Professor Xinghang Zhang ABSTRACT Nanostructured metals have peaked significant interest for automotive and aerospace applications as they can drastically improve a metal's mechanical properties. These structures, including nanocrystalline and nanotwinned metals, can lead to novel deformation behaviors and a significant improvement of mechanical properties. As both devices (nanowires, NEMS) and microstructural features approach the nanoscale, there is an opportunity to elucidate the mechanisms governing deformation in these systems. Micropillar compression provides an avenue to explore their mechanical behavior. New insight to deformation in nanostructured metals can be gained through in-situ videos of micropillar compression in the SEM, as well as post-compression microstructural analysis using TEM. This review focuses on microcompression of nanostructured face centered cubic (FCC) metals due to the abundance of literature on these systems. It also details possible challenges faced with designing micropillar compression experiments and postcompression analysis. Keywords: Micropillar compression, Size effects, Nanostructured Metals, FCC metals, Micromechanical Testing Date: Thurday, October 10, 2019 Time: 8:30 A.M. Place: ARMS 3109

New Locks
by MSE Safety 08 Oct '19

08 Oct '19

Hello Students, For those of you here over fall break, you may have noticed that most of our labs have the new locks on them. How exciting! However, the electronic shop was unable to connect our new locks to the new lab access program today due to some issues on their end. Therefore, I am still not able to add users to the labs. They are supposed to stop by later this week, but currently, our new locks have no users added. Until we are able to update the locks again, MSE Armstrong lab spaces are to be business hours only (8AM-5PM). I am aware that this is not efficient or convenient, but we need our lab spaces to be secure. If you need in a lab space, please have one of the lab techs (Darren, Jenni, Tim, or Tal) let you in. Regards, Jenni

Seminar Notice for Bethany Rutherford's Preliminary Exam. Seminar 8:00 a.m., Thursday, Oct. 17, in ARMS 1028. Review, same day, at 9:00, in ARMS 2237. Exam same day, at 9:30, in ARMS 2237. " Directed Self-Assembly of Oxide-oxide Nanocomposite Thin Films
by Son, Rosemary E 07 Oct '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Directed Self-Assembly of Oxide-oxide Nanocomposite Thin Films" By Bethany Rutherford Purdue MSE Preliminary Exam Advisor: Professor Haiyan Wang ABSTRACT Nanocomposite thin films are materials that have the potential to improve and tune many properties for various applications in electronics, memory storage, and optics. Materials properties are a consequence of their structure, so being able to manipulate the nanostructure of oxide-oxide nanocomposite thin films is important for modifying them for device purposes. Thin film growth involves many factors: diffusion, substrate surface conditions, source material composition, and deposition temperature and rate. The two main approaches to thin film fabrication are bottom-up and top-down. Bottom-up growth focuses on the self-assembly of the nanostructure. This review discusses the merits of different methods that can be used to direct the self-assembly of oxide-oxide nanocomposite thin film growth based on substrate manipulation and the future outlook on this area of research.

Seminar Notice for Sathish K. Ranganathan's Ph.D. Final Exam. Seminar, Wednesday, Oct. 16, at 10:30 a.m., in RHPH 162. Exam same day at 1:00 in ARMS 2119. "Durable Icephobic Coating for Aluminum Substrate"
by Son, Rosemary E 07 Oct '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Durable Icephobic Coating for Aluminum Substrate" By Sathish Kumar Ranganathan Purdue MSE Ph.D. Final Exam Advisors: Professor Jeffrey P. Youngblood and Professor John A. Howarter ABSTRACT Development of durable icephobic coating and reduction of ice accumulation on the product surfaces has proven to be a challenging task in the past decade. To obtain a durable icephobic coating, Fluoro-Ethylene-Alkyl-Vinyl-Ether (FEVE) binder was selected and smooth and rough surface coating formulations were developed. Targeting overhead power transmission line application, FEVE binder-based coating formulations were validated at extreme thermal ageing conditions (200oC for 60 days) and have studied retention of icephobic performance. These coatings were also benchmarked with commercially available silicone-epoxy coating and superhydrophobic aerosol coating. FEVE based coatings had retained its surface characteristics and icephobic performance after aggressive thermal ageing as compare to commercial benchmark coatings. Further to map-out icephobic material design space and to create a scientific understanding, silicone-based coating materials were selected with varying material and surface characteristics such as water contact angle (hydrophilic, hydrophobic and superhydrophobic), surface roughness (3000 GS, 300 GS and 30 GS) and elastic modulus (8 psi to 280 psi). Experiment results suggest that hydrophobic silicone, low modulus coatings ice adhesion strength did not influence by roughness as compare to higher modulus silicone coatings. The critical modulus to obtain a low ice adhesion surface was identified as below 100 psi. Superhydrophobic coating has resulted in low ice adhesion strength across the coating modulus and roughness ranges. Additionally, these silicone coatings were further validated for ice accumulation weight increase using automated ice accumulation test set-up. Superhydrophobic coating has outperformed all other coatings with less ice weight accumulation, however the test sample placement angle against water spray direction significantly affects the ice accumulation test results. These results and learnings were used to establish durable icephobic coating material design space. Date: Wednesday, October 16, 2019 Time: 10:30 A.M. Place: RHPH 162
