Dag Research Group

The cluster from 2020 to 2026 focuses on Advanced Materials for Electrocatalysis and Storage and energy conversion. (2001–2019) era establishes the foundational principles of Salt-Surfactant Liquid Crystals. Research on 1994-2000 focuses on the fundamentals of mesoporous silica morphogenesis and early transition metal interactions.
