COMPOSITES BASED ON CALCIUM PHOSPHATES AND COPPER NANOPARTICLES

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
Copper nanoparticles were synthesized by the borohydride method using polymer stabilizers (polyethylene glycol, polyvinylpyrrolidone). It was found by optical spectroscopy that copper nanoparticles obtained at a molar ratio Cu/ polymer of 1:(3-6) have ...
