Within the scope of preparing his doctoral thesis, Daniel Sippel succeeded in producing and crystallizing
vanadium nitrogenase.
The catalytic center of
vanadium nitrogenase: an iron - vanadium cofactor with an unusual carbonate ligand.
Vanadium nitrogenase found in soil bacteria can in its natural setting perform the same synthesis that is only possible in industrial processes with the aid of extreme pressures and high temperatures.
