Chemistry World has highlighted, in a recent article, work published in NJC by Dr Massimiliano Arca (Dipartimento di Scienze Chimiche e Geologiche, Università degli Studi di Cagliari, Italy) and his colleagues. The authors have made a new oxamate salt that could help protect monuments from weathering. In their study, they show that the introduction of structural modifications on the oxamate anion provides a promising tool for the development of protective agents for calcareous stones.
