(Belgrade : Association of Chemical Engineers, 2005)
Sorption of different ionic species, especially heavy metals, on calcium-hydroxyapatite
Ca10(PO4)6(OH)2, (HAP) and other apatite minerals plays an important role in environmental
chemistry and practical applications of ...
Sintered dental inserts based on ion-doped hydroxyapatite as dentin substitutes
(European Ceramic Society, 2023)
The main drawback of resin-based composites (RBCs) widely used in restorative dentistry presents their volumetric shrinkage during the polymerization that can lead to clinical failures of restorations such asmarginal gap ...
Selection of processing parameters for the integrated supercritical CO2 extraction from green tea leaves and extract impregnation onto starch-chitosan based films
(Elsevier B.V., 2024)
The study aimed toward the development of biocompatible and biodegradable polymeric films (starch-chitosan and starch-chitosan-cyclodextrin) with biologically valuable green tea leaf extract using an environmentally friendly ...
