This typically allows the calculation of instantaneous corro- sion rate and passive film thickness. EIS when coupled with x-ray photoelectron spectroscopy (XPS) analysis can provide oxide metal cation compositions. This enables a synergistic understanding of chemical as well as physical properties of passive films in alloys ranging from binary to complex con- centrated alloys [2] . 4) Mott-Schottky technique: This method is often used to understand the semi- conductor properties of oxides, i.e., whether the oxide is p-type or n-type, the concentration of ionic donors. Know- ing this information helps researchers to recognize the pre- dominant defect pair in their material (e.g., p-type = cation vacancy + anion interstitial), and to relate point defects to electrochemical corrosion behavior, which remains a topic of research today.

WOMEN IN ENGINEERING This profile series introduces mate- rials scientists from around the world who happen to be females. Here we speak with Ingrid M. Padilla Espinosa, postdoctoral researcher, University of California, Merced. What part of your job do you like most? I love doing research because it challenges me. I get to learn new things all the time, and also every day feels different. Plus, I often get to experience the excitement of “Eureka moments.” In my current position I work with graduate students, and it is very satisfying to see them achieving their goals. What is your engineering background? I have a bachelor’s degree in mechanical engineering, and a master’s and doctorate in nanoengineering. What attracted you to engineering? Love for mathematics and curiosity, but my greatest motivation was the possibility to create and modify devices that could benefit hundreds of people. Did you ever consider doing something else with your life besides engineering? I always wanted to be an engineer, but I considered getting into a theater program as a second career. Padilla Espinosa What are you working on now? I’m doing research on the plastic deformation of nanoparticles and their size, shape, and orientation depen- dency, using computational modeling. Are you actively engaged with ASM or its affiliates? Yes, I recently became engaged with the Inclusion, Diversity, Equity, and Awareness (IDEA) Committee. Finish this sentence: Women in materials engineering are… Changing the world by bringing new perspectives that lead to innovative solutions in all fields. Hobbies? Traveling, meeting people, outdoor activities, reading historical novels. Favorite motto or quote? “Everyone you will ever meet knows something you don’t.” – Bill Nye Last podcast listened to? The TED Radio Hour on The Food Connection, highly recommended. Do you know someone who should be featured in an upcoming Women in Engineering profile?

CHAPTERS IN THE NEWS Philadelphia Awards First Centennial Scholarship One hundred years is a significant milestone for any professional asso- ciation and worthy of a celebration. In honoring the past, the Philadelphia (Liberty Bell) Chapter decided to look to the future with the creation of a Cen- tennial Scholarship Fund. The inaugural Centennial Schol- arship (2021) winner, Erika Garro, was awarded $5000 from the Chapter. Garro is a student at Drexel University with a 3.93 GPA. After her 2023 graduation, she’ll have both a B.S. and M.S. in materi- als science and engineering. Garro is active in Drexel’s Mate- rial Advantage Chapter as its membership chair. She is now completing a co-op assignment as an engineering assistant with Exponent Failure Analysis Associates Inc. The Philadelphia Chapter also presented special awards to local high school students participating in the Delaware Valley Science Fair that includes Eastern Penn- sylvania, New Jersey, and Delaware High School students Garro CHAPTERS IN THE NEWS
