A method for surface doping and functionalization of ZnO nanowires (NWs) with Pd (Pd/ZnO) in a one‐step process is presented. The main advantage of this method is to combine the simultaneous growth, surface doping, and functionalization of NWs by using electrochemical deposition (ECD) at relatively low temperatures (90 °C). Our approach essentially reduces the number of technological steps of nanomaterial synthesis and final nanodevices fabrication with enhanced performances. A series of nanosensor devices is fabricated based on single Pd/ZnO NWs with a radius of about 80 nm using a FIB/SEM system. The influence of Pd nominal composition in Pd/ZnO NW on the H2 sensing response is studied in detail and a corresponding mechanism is proposed. The results demonstrate an ultra‐high response and selectivity of the synthesized nanosensors to hydrogen gas at room temperature. The optimal concentration of PdCl2 in the electrol...

The use of biomimetic complexes is a common strategy adopted to obtain valuable information on enzymatic structures and functions. Following our previous investigation on the dioxygenation process of a cysteinato ligand by an efficient [TpMe,Ph FeCysOEt] cysteine dioxygenase (CDO) biomimetic complex, a detailed DFT study is herein presented on two modified systems in which Fe(II) has been replaced by either Ru(II) or Os(II). The reaction mechanism by which such compounds catalyze the formation of cysteine sulfinic acid is fully elucidated and compared with the previous findings on Fe(II)-system. Contrary to what observed for iron, the reaction proceed via multistate reactivity patterns on competing singlet and triplet spin state surfaces. The outcomes of the present investigation allow to assess the changes in the whole process and the difference in reactivity on modification of the metal center while simultaneously...
