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

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.

Carbonate environment changes with Na or K substitution in biomimetic apatites

open access: yes, 2023
International audienceBiological and biomimetic apatites allow incorporations of many cationic and anionic substituents, namely Na+, CO32−, and potentially K+, that influence apatite's physicochemical, thermodynamic, and structural properties.

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

Surface properties of biomimetic nanocrystalline apatites; applications in biomaterials [PDF]

open access: yes, 2014
Several types of nanocrystalline apatites have been described, obtained in various ways. Among these, biomimetic nanocrystalline apatites (BNA), whose characteristics are close to those of biological apatites, have been shown to exhibit specific ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
