Hydrothermal synthesis and thermal evolution of carbonate-fluorhydroxyapatite scaffold from cuttlefish bones

Biomimetic design of bone substitutes based on cuttlefish bone‐derived hydroxyapatite and biodegradable polymers

“…The successful transformation of the aragonite from the cuttlefish bone to hydroxyapatite is indicated by characteristic phosphate ( ) bands at 1086, 1025, 960, 609, and 562 cm −1 and hydroxyl (–OH) group founded at 3571 and 630 cm −1 (Figure ). Hydrothermal conversion has also resulted in non‐stoichiometric carbonated hydroxyapatite indicated by specific doublet of carbonate group ( ) at 1457–1412 cm −1 and carbonate band at 879–872 cm −1 . Mentioned absorption bands of hydroxyapatite are also present in different HA/PCL/PLA scaffolds along with bands associated with polymer phase.…”

Adsorption of nucleotides on biomimetic apatite: The case of adenosine 5⿲ triphosphate (ATP)

“…Synthetic nanocrystalline apatites represent a model for the basic constituent of the inorganic part of bones (65)(66)(67)(68)(69)(70)(71)(72)(73)(74)(75) wt.%, depending on age and sex) [11], with a general formula [34] Ca 10−x (PO 4 ) 6−x (HPO 4 or CO 3 ) x (OH) 2−x with 0 ≤ x ≤ 2. These nanocrystals exhibit in particular special surface features as shown in previous investigations using spectroscopic techniques [35][36][37][38][39][40]: precipitated nanocrystals possess a prominent structured hydrated layer on their surfaces, which is gradually converted into more stable apatite domains during aging.…”

The effect of the natural raw barite and the dolomite material on borate glass formation

“…The carbonates are also revealed at 880-1417 cm -1 [13]. Figure 4 shows the XRD pattern of the investigated glass samples containing raw materials.…”
