Hydroxyapatite crystal

The degree of HAp nucleation and nucleation development on the un-etched titanium plates was lower than that on the etched titanium plates. In vitro bioactivity of HAp-coated titanium testing using SBF solution showed prospective results.

Hydroxyapatite (HA) is one of the most important calcium phosphate minerals due to its application in orthopaedics and dentistry. The applications of the synthesized HA powder depend upon the morphology of the HA. In this research, hydroxyapatite crystal nanowires are synthesized by simple hydrothermal method from clamshells.

Zinc hydroxyapatite coatings (ZnHAp) were synthesized on 316L stainless steel by ion exchange method between hydroxyapatite coatings (HAp) and solution containing Zn(NO3)2. Effect of the initial concentration of Zn2+ and contact time to ion exchange process was studied. The analytical results of FTIR, SEM, Xray, and AAS showed that the obtained coatings were single phase crystals of HAp, and the present of Zn in HAp structure with the atomic ratios of Zn/Ca, (Ca + Zn)/P of 0.143 and 1.707 changed the morphology, the crystal diameter and the lattice parameters.

Polylactide (PLA)-hydroxyapatite (HAp) composite components have attracted extensive attentions for a variety of biomedical applications. This study seeks to explore how the biocompatible PLA matrix and the bioactive HAp fillers respond to thermo-mechanical environment of a PLA-HAp composite manufactured by 3D printing using Fused Filament Fabrication (FFF). The insight is obtained by in situ synchrotron small- and wide- angle X-ray scattering (SAXS/WAXS) techniques.

Hydroxyapatite doped carbon nanotubes (HAp/CNTs) was synthesized successfully as a coating on the surface of titanium alloy (Ti6Al4V) by a scanning potential method. The biomineralization of the materials soaked into a simulated body fluid (SBF) solution was investigated.

Tetracycline was introduced in the middle of the twentieth century and was used widely for the relief of nausea associated with morning sickness. In 1963, the Food and Drug Administration (FDA) issued a warning against the use of tetracycline as an antibiot- ic for young children and pregnant women due to irreversible dental staining. Tetracycline affects the teeth during the formation period, ranging from the embryo in the second trimester of pregnancy to the eighth year of the child’s life.
