摘要： In the framework of research devoted to development of new synthetic methods for alkali niobates with emphasis on the principles of green chemistry, the first example of the efficient synthesis of K0.5Na0.5NbO3 powders from pure aqueous solution under normal reaction conditions is presented. Aqueous solutions of stable Nb(V)-peroxo-citrate at pH 8.50 or Nb(V)-peroxo-glycine at pH 5.50 chelate complexes were prepared, characterized and studied with FT-IR and UV-Vis spectroscopy. The addition of sodium and potassium acetates or nitrates led to the final aqueous precursor solution and it was shown that single phase K0.5Na0.5NbO3 nanopowders could be obtained by simple calcination of these peroxide intermediates at the desired, relatively low temperature (500-550 degrees C). The results showed that the particle size and morphology, analysed by FE-SEM, strongly depended on the type of Nb(V)-peroxo precursor and the annealing temperature. K0.5Na0.5NbO3 particles prepared through the Nb(V)-peroxo-citrate precursor resulted in the formation of sharp-edged nanocuboids in the size range 50-200 nm, while the synthetic route through the Nb(V)-peroxo-glycine precursor surprisingly also enabled formation of particles with rod-like morphology.

摘要： Despite the increasing interest of the scientific community in carbon nanotubes and graphene, fullerene C-60 still plays an important role in the family of nanocarbons. A quarter of a century of research on fullerenes has been dedicated to understanding the way to produce stable, well-characterized and highly soluble fullerene derivatives, which retain the original properties of C-60. The applications in a wide number of fields, especially on new materials design, have enriched the literature with fascinating examples where fullerenes are directly involved. We report here a brief summary of recent achievements in some exciting applications of fullerene derivatives.
