In the last decades, a considerable effort has been focused on nanostructured materials (NMs), trying to find the correlation between structure and unexpected characteristics, which otherwise would not be possible at longer scales. NMs possess unique and widely tunable physicochemical properties, enabling unconventional applications to be achieved, ranging from nanomedicine, environmental science, catalysis to optoelectronics and energy conversion.

The design, synthesis and functionalization methods of NMs are oriented to a smart tailoring of the morpho-structural properties with the aim of improving their processability and applicability. However, the “perfect” material suitable for each application, requires precise control on the molecular and electronic structure as well as of the morphology of the nanomaterial.

Novel functionalised NMs require innovative design techniques, that foresee the creation of new paths where theoretical approaches walk side by side with modern synthetic methodologies and characterizations. The last decades saw the rise of theoretical and computational as a powerful tool to either predict on a mesoscopic scale (coarse graining, multiscale) the main features that would optimise the functionalisation of the designed materials, or to focus on very specific (atomistic) mechanisms unveiling the origins of specific properties in the materials.

Among others, the wet synthesis methods of nanomaterials possess a unique versatility to obtain different shapes, sizes and external functionalizing layers, which in turn prove to be an easy path for the customization of their properties.

Recently, the possibility to conjugate spectroscopic techniques with microscopy at nanometric level, as for example by combining X-ray spectroscopy with electron microscopy (SPELEEM), elicits a huge interest. Another issue that is having a very big development is the possibility to carry on X-ray photoemission experiments in non-UHV conditions, as in near ambient photoelectron spectroscopy (NAP), using a cell or an electrospray beam of nanoparticles in solution.

This collection focuses on the design, synthesis and advanced characterizations of functional NMs, e.g. metal, metal oxides, and hybrid nanoparticles by means of state-of-the-art spectroscopic and imaging techniques.
