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 ...

Ostrich Eggshell as an Alternative Source of Calcium Ions for Biomaterials Synthesis [PDF]

open access: yesMaterials Research, 2017
Ostrich eggshells are a potentially abundant and a high purity and low cost source of calcium to produce β-Tricalcium Phosphate (β-TCP) and Hydroxyapatite (HA), important calcium phosphates used as biomaterials. Here, we use a wet precipitation procedure
