Magalí Lingenfelder is an Argentinian chemist who is head of the Max Planck Laboratory for Molecular Nanoscience in École Polytechnique Fédérale de Lausanne. Her work looks to control atomic interfaces for energy conversion and antimicrobial surfaces. She was awarded the Max Planck Society Otto Hahn Medal in 2008.

Early life and education

Lingenfelder is from Argentina. She was an undergraduate student at the National University of Córdoba. She completed her Master's thesis at the Max Planck Institute for Solid State Research, where she worked on metal-organic coordination complexes.[1] She remained in Germany for her doctoral research, for which she was awarded the Otto Hahn Medal in 2008. Her doctoral research investigated sub-molecular resolution of chiral recognition processes.[2]

Research and career

After her PhD, Lingenfelder was a postdoctoral researcher at the Spanish National Research Council Institute of Materials Sciences of Barcelona (Instituto de Ciencia de Materiales de Barcelona) and the Molecular Foundry.In 2013, Lingenfelder joined the École Polytechnique Fédérale de Lausanne. Her research investigates the development of carefully controlled molecular assemblies which can respond to external stimuli.[3] Typically, these interactions are determined by energy or charge transfer processes.[3]

Lingenfelder showed that it was possible to boost the oxygen evolution reaction (OER) in electrocatalytic water-splitting by functionalising hybrid 2D electrodes with helicene molecules.[4] Specifically, she evaluated the role of chirality by comparing the impact of chiral fused thiadiazole-helicene molecules with 2,1,3-benzothiadiazole, an achiral molecule, on oxygen evolution reactions. She showed that the boost in OER was not solely due to interactions between the thiadiazoles and electrode surfaces. This study also confirmed previously claims of Chiral Induced Spin Selectivity ('CISS') explains that hydrogen peroxide formation is prohibited at spin polarising surfaces.
