Abstract Taking advantage of the flexibility apatite structure, nano- and micro-particles hydroxyapatite (HAp) were doped with different combinations rare earth ions (RE 3+ = Gd, Eu, Yb, Tm) to achieve a synergy among their magnetic optical properties enable application in preventive medicine, particularly diagnostics based on multimodal imaging. All powders synthesized through hydrothermal processing at T ≤ 200 °C. An X-ray powder diffraction analysis showed that all crystallized P 6 3 / m...
Phase composition, crystal structure and morphology of biological hydroxyapatite (BHAp) extracted from human mandible bone, carbonated (CHAp), synthesized by the chemical precipitation method, were studied x-ray powder diffraction (XRD), Fourier transform infrared (FTIR) Raman (R) spectroscopy techniques, combined with transmission electron microscopy (TEM). Structural microstructural parameters determined through Rietveld refinement recorded XRD data, performed using FullProf computing...
A series of cobalt-exchanged hydroxyapatite (CoHAp) powders with different Ca/Co ratios and nominal unit-cell contents Ca 10− x Co (PO 4 ) 6 (OH) 2 , = 0, 0.5, 1.0, 1.5 2.0, were synthesized by hydrothermal treatment a precipitate at 473 K for 8 h. Based on ICP (inductively coupled plasma) emission spectroscopy analysis, it was established that the maximum amount cobalt incorporation saturated ∼12 at.% under these conditions. The effects content CoHAp investigated using spectroscopy,...
Pure and cobalt-exchanged hydroxyapatite (HAp CoHAp) powders were synthesized by hydrothermal method. X-ray diffraction (XRD), Raman spectroscopy, particle size analysis, inductively coupled plasma (ICP) emission scanning electron microscopy (SEM) used to study the microstructural unit cell parameters, average size, distribution, chemical composition, morphology of powders. XRD spectroscopy confirmed that samples free from impurities other phases calcium phosphates. It has been found...
Transformations between amorphous and crystalline apatite mechanistically govern some of the most essential processes in bone metabolism, including biomineralization remodeling.
In this study, ZnO as a semiconductor and RuO2 metal-like conductor were combined in composite tested photoanode for water splitting, i.e. green hydrogen oxygen production. ZnO/RuO2 the mass ratio of 2:1 was prepared using microwave processing precipitate. To investigate influence vacancies defects crystal structure on (photo)electrocatalytic efficiency production, annealed at 300 600?C. The phase composition, morphology, optical properties as-prepared composites analyzed detail. activity...
Mechanical milling of commercial ZnO and SnO<sub>2</sub> was used to produce a ZnO/SnO<sub>2</sub> composite with high density surface defects; in particular, zinc interstitials (Zn<sub>i</sub>) oxygen vacancies (<italic>V</italic><sub>O</sub>).

Rietveld refinement XRD data...
ZnO nanopowders were produced using microwave processing of a precipitate and applied as photoanode for photoelectrochemical water splitting. Two different surfactants, cetyltrimethylammonium bromide (CTAB) the cationic Pluronic F127 non-ionic one, employed to in situ adjust surface-to-bulk defect ratio crystal structure further modify photo(electro)catalytic activity photoanode. The structure, morphological, textural, optical properties particles studied detail explain profound effects...
Catalytic materials are the greatest challenge for commercial application of water electrolysis (WEs) and fuel cells (FCs) as clean energy technologies. There is a need to find an alternative expensive unavailable platinum group metal (PGM) catalysts. This study aimed reduce cost PGM by replacing Ru with RuO2 lowering amount adding abundant multifunctional ZnO. A ZnO@RuO2 composite in 10:1 molar ratio was synthesized microwave processing precipitate green, low-cost, fast method, then...
