03 May '22

Hello Everyone, I am glad to announce that at the ChE Safety Committee's recommendation, Dr. Corti appointed the following graduate students to serve on the ChE Safety Committee for the next two years, effective May 1st , 2022: 1. Melissa Marsing (advised by Dr. Morgan) 2. Dharini Varadharajan (co-advised by Dr. Dou and Dr. Boudouris) At the same time, on behalf of the ChE Safety Committee, I would like to thank Siddhartha Akkiraju and Arnav Deshpande for their exemplary service on the safety committee over the last two years. Their effort and input in the safety committee work helped increase the safety culture in our School! We wish them all the best as they are getting ready to embark in their new careers. Many thanks to David Dean as well, for his outstanding service on the safety committee as the GSO safety officer on the committee for the last two years; we are looking forward to welcoming the next GSO safety officer on the safety committee and to working with them over the next year. Sincerely, Gabriela On behalf of the ChE safety Committee __________________ Gabriela Nagy, PhD Industrial Education Director Davidson School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>

**REMINDER** Graduate Seminar Series - TODAY - Faculty Lectureship - Siddhartha Akkiraju (MANDATORY FOR ALL PHD STUDENTS)
by Waling, Robin M 28 Apr '22

28 Apr '22

Dear All, On behalf of Purdue University's Davidson School of Chemical Engineering, we are glad to announce our upcoming Graduate Seminar Series Lecturer Siddhartha Akkiraju from the Department of Chemical Engineering, Purdue University. He will be presenting at Purdue University on Thursday, April 28, 2022. You will find further detail regarding the lecture at the end of this email. [https://marketing.purdue.edu/Email/TemplateSets/ChE/Templates/Template04/Im…]<https://engineering.purdue.edu/ChE> Graduate Seminar Series [cid:image002.jpg@01D858AA.44EA25B0] Siddhartha Akkiraju Chemical Engineering Purdue University Biography: Siddhartha Akkiraju obtained his B.S. in chemical engineering in 2017 from the University of California, San Diego. While in undergrad he worked in Professor Ratnesh Lal's group on the synthesis and functionalization of Janus nanoparticles. After arriving at Purdue, he joined Professor Bryan Boudouris' group. At Purdue he studies the structure-property relationships of radical polymers to design and develop the next generation of macromolecules for organic electronic devices. ******* ******* Structure-Magnetic Property Relationships in Radical Polymers Thursday, April 28, 2022 3:00 p.m. - 4:15 p.m. FRNY G140 - Reception at 2:30 PM- Abstract: Recently, there has been significant increase in research and development in the field of organic electronics. This is mainly because organic electronic devices can be flexible, lightweight, and processed from solution using low-cost manufacturing techniques. Typically, these devices have utilized conjugated polymers as their active layer components. This approach has been successful, but the use of conjugated polymers comes with limitations. To address these limitations and expand the field of organic electronics, this work studies a novel class of macromolecules, radical polymers. Unlike their conjugated polymer counterparts, radical polymers are comprised of a non-conjugated backbone with stable open-shell groups at their pendant sites. This work quantifies the electron exchange behavior of poly(4-glycidyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl) (PTEO). Due to the high number of pendant open-shell sites, PTEO displays strong paramagnetic behavior. Electron paramagnetic resonance spectroscopy revealed that 4-hydroxy-2,2,6,6-tetramethylpiperidin-N-oxy (TEMPO-OH), 4-glycidyloxy-2,2,6,6-tetramethylpiperidine-1-oxyl (TEO), and PTEO showed rapid electron exchange between the pendant radical groups. When compared to TEMPO-OH and TEO, there was more interaction between the unpaired electrons in PTEO due to their proximity along the polymer chain. This phenomenon was confirmed through magnetic susceptibility, Xm, measurements between 2 K and 300 K. At 2 K, TEMPO-OH and TEO had a Xm of 1.8×10-2 emu mol-1 and 4.6×10-2 emu mol-1. PTEO on the other hand, had a Xm of 1.3×10-1 emu mol-1. Due to its amorphous nature, PTEO had weak antiferromagnetic interactions. However, thin films of PTEO with TEMPO-OH additives showed increased antiferromagnetic interactions between the open-shell sites as well as stronger magnetoresistance effects. In conclusion, radical polymers offer researchers an opportunity to explore an underutilized class of macromolecules. By studying the structure-property relationships, we can gain better insight into radical polymers and develop novel materials for the next generation of organic electronics. ******* ******* Davidson School of Chemical Engineering<https://engineering.purdue.edu/ChE> Purdue University West Lafayette, IN 47907 (765) 494-4050<tel:+17654944050> © 2022 Purdue University<http://www.purdue.edu/purdue/disclaimer.html> All rights reserved An equal access/equal opportunity university<http://www.purdue.edu/purdue/ea_eou_statement.html>

Enforcement of FRNY Conference Room Policy
by Gonzalez, Joshua 27 Apr '22

27 Apr '22

Dear All, In light of recent issues with conference rooms and the School's policy regarding them, we will begin enforcing the need to contact one of the administrative assistants in order to reserve a conference room. Any calendar invite without sufficient information that is sent to any of the conference room calendars will be declined due to it being an out of policy request. These new changes should not affect those with current permissions for making reservations but rather close the loophole for bypassing reservation approval for those without appropriate permission. To reserve a conference room, please visit any of our administrative assistants or contact our Main Office either via phone (765-494-4050) or email (chemain(a)purdue.edu<mailto:chemain@purdue.edu>). This will help ensure a more efficient use of resources for our school as well as make sure that they are being appropriately used/scheduled. Sincerely, Joshua --- [Davidson_H-Full-CMYK_1200px] <https://engineering.purdue.edu/ChE> Joshua Gonzalez Operations Coordinator [Phone_1D_11x16px] (765) 494-4365 | [Fax_1D_16x16px] (765) 494-0805
