(Sociedad Chilena de Química, 2015)The macromolecular complexes Chitosan center dot(PtCl2)(n) and PSP-co-4-PVP center dot(PtCl2)(n), were prepared from the respective polymer and PtCl2 in metal: polymer molar ratios 1: 1 and 1: 5. Pyrolisis of the macromolecular ...
-
(American Chemical Society, 2021)Thoria was prepared using a solid-state method from the macromolecular precursor Chitosan center dot Th(NO3)(4) (chitosan) and PS-co-4-PVP center dot Th(NO3)(4) (PVP). The morphology and the average size of ThO2 depend of ...
