Over a nice cup of coffee, check out the paper on the 4D tomography analyses of coffee beans from different parts of the world. In this fun paper, I look at the evolution of the internal microstructure of coffee bean as it undergoes roasting. I use X-ray Computed Tomography and time-interrupted analyses to see what makes the coffee beans from different parts of the coffee belt so different.
In this article, we analyze the occurrence of slip transfer across grain boundaries in a thin pure Ti sample, combining SEM, EBSD, and 3D non-destructive microstructural characterization through LabDCT. We collected an extensive database of slip transfer, partial slip transfer, and slip blocking events, and assessed the performance of different slip transfer criteria through the F1 score.
A big thank you to the TRACER grants program at the Purdue University College of Engineering for selecting me as one of the inaugural recipients. I look forward to collaborating with Prof. Martina Zimmermann and Prof. Markus Kästner at Technische Universität Dresden. This grant will pave the way for our collaborative efforts in data-driven materials research. The TRACER Grants program is an excellent resource for doctoral and postdoctoral researchers at Purdue to foster international collaboration and interdisciplinary research. I congratulate my cohort of TRACER grant recipients for this achievement.
In this paper, we characterize the crystallographic grain structure in Pure Titanium using advanced Diffraction Contrast Tomography (DCT). We use a Helical Phyllotaxis DCT (HP-DCT) acquisition strategy to capture the 3D grain structure of commercially pure Ti at the lab scale and quantitatively compare the DCT grain maps and grain boundary locations against ground-truth EBSD and SEM data to assess fidelity.
Results indicate that the HP-DCT acquisition approach captures 3D grain maps with high fidelity while saving acquisition and analysis time, especially for larger samples.
Panel - careers at R1 Universities.
If you are interested in a career as faculty in an R1 University in the USA, have a look at this panel discussion comprising panelists from Northwestern University (Dr. Ian McCue), The University of Minnesota (Dr. Sayan Biswas), and The University of New Hamshire (Dr. Fei Han). My colleagues and I moderated the panel as a part of seminar series hosted by the Engineering Academic Career Club (EACC) in the Fall of 2022 at Purdue University..
