Biomimetic apatite sintered at very low temperature by spark plasma sintering: Physico-chemistry and microstructure aspects [PDF]

open access: yes, 2010
Nanocrystalline apatites analogous to bone mineral are very promising materials for the preparation of highly bioactive ceramics due to their unique intrinsic physico-chemical characteristics.

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

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.

Characterization of a calcium phospho-silicated apatite with iron oxide inclusions [PDF]

open access: yes, 2011
An iron oxide containing calcium phosphate–silicate hydroxyapatite was synthesized by calcination at 900 °C of a sample obtained by precipitation in basic aqueous solution of Ca, P, Si, Fe and Mg containing acidic solution made from dissolution of ...

Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

open access: yes, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

Apatite Formation on Titanium Containing Apatite

open access: yesBioceramics Development and Applications, 2013
Some titanium containing apatite (TMA) ceramics prepared by wet synthesis was superior to Hydroxyapatite (HAp) ceramics of mechanical property and cutting performance. In this study, we investigated chemical reaction of TMA in a body environment. Each TMA or commercial Hydroxyapatite powder (HAp) was formed to circular pellets by uniaxial pressing. The

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

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 ...

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.

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
