Sustainability means conserving the use of resources such as habitat, raw materials, energy or human labor. Sustainability can only be achieved if it is pursued on three levels: environmental, economic and social. In this approach the three areas of chemistry address three different aspects, such as energy, circular economy and environmental remediation that take into account this message.

Applied organic chemistry involves applying its principles and techniques in several fields, such as pharmaceuticals, materials science, agriculture, and biochemistry, by synthesising, analysing, and testing organic compounds for specific uses. Here are some areas where applied organic chemistry is prevalent: i) Designing and synthesizing new biological compounds, enhancing the synthetic methodologies from a greener point of view. ii) Polymer Science: Creating and modifying organic polymers in plastics, textiles, and coatings. iii) Organic chemistry and Chemical Biology: Design and synthesis of organic small molecules of pharmacological interest against complex diseases.

The attached poster describe a work i did on operando investigations on photocatalytic materials for green hydrogen production. Investigating the electronic and structural dynamics of a catalyst in operando conditions has a crucial role in the development of more performant electrochemical devices. I describe a novel electrochemical cell for operando XAS measurements in fluorescence mode. The thin layer of flowing electrolyte allows to probe energies as low as the Ti K-edge. An advanced setup to perform XAS measurement under PEC conditions is also described. The PEC setup is now available to the scientific community at the SAMBA beam line. As case study, we report the operando XAS measurements at the Fe and Ni K-edges on thin Ni-doped maghemite films (111) epitaxially grown on Pt (001) single crystal substrates. We describe the role of Ni doping in the catalytic performances of maghemite for the oxygen evolution reaction.
