Oxygen isotopic compositions of aluminum-rich chondrules from CH chondrites. Five out of eight chondrules analyzed exhibit large internal-isotopic heterogeneity, whereas others are isotopically uniform; all chondrules have porphyritic minerals. In contrast to aluminum-rich chondrules in ordinary chondrites, oxygen isotopic heterogeneity is due to the presence of relict CAIs. These relict CAIs are chondrules, being composed of hibonite, grossite, melilite, perovskite, and platinum group metals.

Calcium phosphates are highly biocompatible and in addition, they funtions as osteoconductive scaffolds with the usage of bone. When placed adjacent to bone, osteoid is formed on the surface of the calcium phosphate with tissue damage. Calcium phosphate can also be loaded with cement and can be used to prevent and to treat calcium deficiencies.

The applications of calcium carbonate nanoparticles (NPs) have gained systems to cancerous tissues and cells due to their accessibility and slow biodegradability. A variety of other approaches have been explored or use this phenomenon to deliver drugs via pH-responsive NPs and cell-penetrating peptides. Among the various methods to control the acidic TME and enhance drug delivery (acid-neutralizing Carbonated calcium nanoparticles).
