Mechanism of incorporation of zinc into hydroxyapatite.
The atomic level mechanism of incorporation of Zn(2+) into hydroxyapatite (HAp), which is a potential dopant to promote bone formation, was investigated, based on first principles total energy calculations and experimental X-ray absorption near edge structure (XANES) analyses. It was found that Zn(2+)-doped HAp tends to have a Ca-deficient chemical composition and substitutional Zn(2+) ions are...
متن کاملDurable Self-Cleaning Coatings for Architectural Surfaces by Incorporation of TiO2 Nano-Particles into Hydroxyapatite Films
To prevent soiling of marble exposed outdoors, the use of TiO₂ nano-particles has been proposed in the literature by two main routes, both raising durability issues: (i) direct application to marble surface, with the risk of particle leaching by rainfall; (ii) particle incorporation into inorganic or organic coatings, with the risk of organic coating degradation catalyzed by TiO₂ photoactivity....
متن کاملIncorporation of Flipped Learning into EFL Classrooms Performance and Perception
Innovative mobile-based tools have made new opportunities for learners to spend more quality time inside the classrooms. Keeping this in mind, the present study sought to examine the effect of the flipped classroom on developing EFL learners’ speaking and listening skills. To do so, 60 EFL students from two universities in Iran were assigned into one of the classes of flipped and conventional g...

متن کاملZinc incorporation into hydroxylapatite.
By theoretical modeling and X-ray absorption spectroscopy, the local coordination structure of Zn incorporated into hydroxylapatite was examined. Density function theory (DFT) calculations show that Zn favors the Ca2 site over the Ca1 site, and favors tetrahedral coordination. X-ray absorption near edge structure (XANES) spectroscopy results suggest one dominant coordination environment for the...
