Prof. Gerhard Sperl: a lifetime connecting metallurgy’s past and present

~ Matheus A. Tunes ~ Leave a comment

There are scientists whose work is best understood through instruments, and there are those whose work is best understood through time. Gerhard Sperl – who passed away on Easter Monday, 5 April 2021, at the age of 84 — belonged firmly to the second kind, though he was thoroughly at home with the first. Born … Continue reading Prof. Gerhard Sperl: a lifetime connecting metallurgy’s past and present

New Preprint: Unlocking Nanoscale Detail in Aluminium Alloys with DPC Segmentation

~ Matheus A. Tunes ~ Leave a comment

We are pleased to share our latest preprint, now available on arXiv: Unlocking nanoscale microstructural detail in aluminium alloys through differential phase contrast segmentation in STEM (arXiv:2603.11643). In this work, we show how differential phase contrast (DPC) imaging in scanning transmission electron microscopy can be turned into a powerful, quantitative tool for characterising the microstructures … Continue reading New Preprint: Unlocking Nanoscale Detail in Aluminium Alloys with DPC Segmentation
