About

Achim Walter Hassel is a leading figure in electrochemical materials science, with a particular focus on corrosion, surface analysis, and the development of novel electrochemical measurement techniques. His major contributions lie in the design and application of scanning droplet cell microscopes (SDCM), which enable high-resolution, localized electrochemical investigations of material surfaces. A standout achievement is his work on "Highly customisable scanning droplet cell microscopes using 3D-printing" (2015), which has garnered 67 citations, demonstrating the field's embrace of his open-source, adaptable approach. This innovation has significantly lowered the barrier for researchers to perform precise, microscale corrosion studies and surface analysis. Beyond this, Hassel's research has advanced the understanding of passive film formation, metal dissolution, and the electrochemistry of complex alloys, with his work frequently cited in top materials and corrosion journals. His impact is further evidenced by his role in shaping the next generation of scientists, combining rigorous fundamental science with practical tool development. For students and researchers, Hassel exemplifies how creative engineering—like integrating 3D printing into electrochemical setups—can transform a field, making sophisticated analysis more accessible and reproducible.
