Today’s emerging questions in colloidal science go far beyond the precise control of size. The synthetic and theoretical efforts focus on a wide range of nanomaterials with unique electronic properties as they carry on a potential to have impact on highly relevant societal themes ranging from electronic devices, energy conversion to energy storage. The particularly important recent examples include the transition metalchalcogenides (TMS), and nitrides (TMN). In this context studying the electronic structure of the central metal atom and differentiating between various metal ligands during synthesis has become of paramount importance for the chemistry of materials.The new high-energy resolution emission spectrometers (microXES and tender) at ESRF enable in situ XES experiments with high energy, time and spatial resolution. However, what is missing is a dedicated sample environment for on-line monitoring of the syntheses of nanostructure in solution at the relevant conditions.
