Marine-Inspired Approaches as a Smart Tool to Face Osteochondral Regeneration

open access: yesMarine Drugs, 2023
The degeneration of osteochondral tissue represents one of the major causes of disability in modern society and it is expected to fuel the demand for new solutions to repair and regenerate the damaged articular joints.

Geochemistry of apatite in various felsic rocks of the Piranshahr plutonic complex: an approach to investigate magmatic evolution [PDF]

open access: yesعلوم زمین خوارزمی, 2023
The felsic intrusive rocks in the Piranshahr plutonic complex consist of three groups: syenite, nepheline-syenite, and alkali-feldspar granite. They are co-genetic and formed approximately 40 million years ago.

Origin of magnetite and apatite ores in the Esfordi magnetite-apatite ore deposit NE of Bafq, south Yazd: insights from mineralogy, geochemistry, microthermometry, O-H stable and U-Pb and Nd-Sm non-stable isotopes

open access: yesJournal of Economic Geology, 2022
Petrographic and mineralogical data indicate the widespread presence of five generations of apatite, two generations of monazite with minor xenotime in the Esfordi deposit.

A Study on Apatite from Mesozoic Alkaline Intrusive Complexes, Central High Atlas, Morocco

open access: yesCrystals, 2022
There are abundant phosphate mines in the High Atlas Mountains of Morocco. Gem-quality apatite is produced at the Anemzi deposit, but its associated gem mineralogy is relatively poorly studied.

Thermal annealing of fission tracks in synthetic apatites [PDF]

open access: yes, 2010
Synthetic analogues of poor-silicated natural apatites have been doped with uranium. These minerals have been irradiated with a thermal neutron dose in the aim to induce the 235U fission and to obtain a fission track population.

Preliminary characterization of calcium chemical environment in apatitic and non-apatitic calcium phosphates of biological interest by X-ray absorption spectroscopy [PDF]

open access: yes, 2005
Several reports have mentioned the existence of non-apatitic environments of phosphate and carbonate ions in synthetic and biological poorly crystalline apatites.

Simultaneous incorporation of magnesium and carbonate in apatite: effect on physico-chemical properties [PDF]

open access: yesMaterials Research, 2013
Synthetic apatites are widely used both in the dental and the orthopaedic fields due to their similarity in composition with the inorganic phase of hard tissues.

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
