Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

open access: yes, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.

Volatile Characteristics of Apatite in Dacite from the Eastern Manus Basin and Their Geological Implications

open access: yesJournal of Marine Science and Engineering, 2022
As one of the youngest back-arc basins, the evolutionary behavior of magmatic volatiles in the Eastern Manus Basin has been poorly studied. Recently, apatite has received widespread attention for its powerful function in recording information on magmatic

Thermal history of the early Miocene Waitemata Basin and adjacent Waipapa Group, North Island, New Zealand [PDF]

open access: yes, 1999
Apatite fission track (AFT) and vitrinite reflectance (VR) data for early Miocene outcrops from the Waitemata Basin reveal that the basin sequence was subjected to shallow burial before denudation.

Biocompatibility and biodegradation analysis of Nile Tilapia gelatin and apatite membranes [PDF]

open access: yesRevista Ciência Agronômica, 2022
Fish farming by-products could represent large-scale raw materials for xenogeneic implants that could be used for bone regeneration. The objective of this research was to analyze the biocompatibility and biodegradation of gelatin (G) and apatite (A ...

Physico-chemical and thermochemical studies of the hydrolytic conversion of amorphous tricalcium phosphate into apatite [PDF]

open access: yes, 2005
The conversion of amorphous tricalcium phosphate with different hydration ratio into apatite in water at 25 °C has been studied by microcalorimetry and several physical–chemical methods.

Study of Thermal Activated CO2 Extraction Processes from Carbonate Apatites Using Gas Chromatography [PDF]

open access: yesЖурнал нано- та електронної фізики, 2015
The study of carbonate in the structure of carbonate-containing apatites (CCA) is an actual problem due to the similarity of such systems to natural apatites of mammalian bone tissue. The search of the optimal synthesis procedures was also carried out in

Hydrolytic Degradation and Bioactivity of Electrospun PCL-Mg-NPs Fibrous Mats

open access: yesMolecules, 2023
In this work, the in vitro degradation behavior of nanofibers was investigated in phosphate buffer solution (PBS) and simulated body fluid (SBF) to study their degradation behavior, as well as their bioactivity.

Adsorption and release of BMP-2 on nanocrystalline apatite-coated and uncoated hydroxyapatite/b-tricalcium phosphate porous ceramics [PDF]

open access: yes, 2009
The association of bone morphogenetic proteins (BMPs) with calcium phosphate bioceramics is known to confer them osteoinductive properties. The aim of this study was to evaluate the surface properties, especially regarding recombinant human BMP-2 (rhBMP-

Exhumation of the Sierra de Cameros (Iberian Range, Spain): constraints from low-temperature thermochronology [PDF]

open access: yes, 2008
We present new fission-track and (U–Th)/He data from apatite and zircon in order to reconstruct the exhumation of the Sierra de Cameros, in the northwestern part of Iberian Range, Spain. Zircon fission-track ages from samples from the depocentre of the

Silicate apatite phosphors for pc-LED applications; pp. 383–395 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2017
Single-phase ceramic samples of silicate apatites M2Ln8(SiO4)6O2 (M = Mg, Ca, Sr; Ln = Y, La) undoped and doped with Eu3+, Ce3+, or Mn2+ ions were obtained by the high-temperature solid-state reaction technique using precursors synthesized under ...
