Highly porous three-dimensional biodegradable scaffolds was obtained from beta-tricalcium phosphate-hydroxyapatite bioceramic (BCP), PCL, and Angiotensin-(1-7). We used the solvent casting and particulate leaching methods (SC/PL). The processed scaff

ABSTRACT The carbonation process is one of the factors that cause a reduction in the hydrogenionic potential (pH) in cementitious composites, which can lead to a depassivation of the reinforcement structures, thus furnishing conditions for a corrosio
