ZnO nanorod arrays fabrication via chemical bath deposition: Ligand concentration effect study
2010
A new ligand, N, N, N', N'-tetramethylethylenediamine, has been used to grow ZnO nanorods on silicon substrates via a two steps approach. A preliminary seeding on silicon substrates has been combined with chemical bath deposition using a Zinc acetate - N, N, N', N'-tetramethylethylenediamine aqueous solution. The used diamino ligand has been selected as Zn(2+) complexing agent and the related hydrolysis generates the reacting ions (Zn(2-) and OH(-)) responsible for the ZnO growth. The seed layer has been annealed at low temperature (<200 degrees C) and the ZnO nanorods have been grown on this ZnO amorphous layer. There is experimental evidence that the ligand concentration (ranging from 5 t…

Recognition and Support of ICCAs in Italy
2012
The concept of ICCA was introduced and first discussed in Italy during two workshops held in 2004 and 2005. The notion very well fits the tradition domestically known in terms of common properties (CPs) and ‘civic uses’ lands (proprietà colletive e demani civici), a category referring to lands and the natural resources used in common by a community. They include a diversity of governance solutions derived from their different historical recognition. CPs and civic uses lands in Italy achieved recognition under agricultural law and were particularly associated to the agro-forestry and pastoral sector. They have been subject to regulations of restrictions on change of land use and protected by…
