Therefore, the B-type CHA is commonly used for bone tissue engineering.
Therefore, all B-type CHA samples are candidates in bioceramic materials for bone tissue engineering applications.
Thus, B-type CHA has been expanded for bone tissue engineering applications.
All B-type CHA samples based on eggshells are candidates in bioceramic materials for bone tissue engineering applications based on these characteristics.
