Pantoya J.W. Wright Regents Chair in Mechanical Engineering and Professor Department of Mechanical Engineering, Texas Tech University Website<https://www.depts.ttu.edu/me/faculty/michelle_pantoya/index.php> Bio: Dr. Michelle Pantoya received her PhD from the University of California, Davis in 1999 and joined the faculty in the Mechanical Engineering Department at Texas Tech University in 2000. As the J. W. Wright Regents Endowed Chair Professor, her research focuses on studying metal particle combustion in ways that can enhance our national safety and security. She has received many research awards including the US Presidential Early Career Award (PECASE) and the DoD Young Investigator Program Award and has 5 patents and over 200 journal publications on this topic. Dr. Pantoya is also an advocate for early engineering education with DOD and DOE STEM grants that promote the development and integration of educational tools and models for culturally and linguistically diverse students. She is also the co-author of several children’s books introducing engineering to young kids (i.e., Engineering Elephants, Designing Dandelions, Optimizing an Octopus). ******* ******* "Surface Chemistry Promoting Metal Particle Combustion" Thursday, March 23, 2022 3:00 p.m. – 4:15 p.m. FRNY G140 Abstract: Micron scale aluminum (Al) particles are notoriously plagued with incomplete combustion and sluggish ignition. One way to increase overall Al reactivity is through surface reactions with the aluminum oxide shell. This presentation will focus on a new synthesis strategy for core-shell aluminum particles that can enhance metal particle reactive performance in explosive applications. The strategy balances activation energy threshold with ignition sensitivity metrics required to safely handle fuel powder. The core-shell structure is aluminum fuel that is passivated by a halogenated shell that purposefully provides oxygen gas at relevant time scales for metal oxidation reactions. Details of the synthesis process will be discussed, and results of reactive performance also highlighted. Harnessing more of the abundant chemical energy stored in an Al particle (i.e., theoretically estimated specific energy is 31 MJ/kg) will have tremendous benefits for the use of Al as an energy generating material in many applications. ******* ******* Davidson School of Chemical Engineering<https://engineering.purdue.edu/ChE> Purdue University West Lafayette, IN 47907 (765) 494-4050<tel:+17654944050> © 2023 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>
