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...
Silver powders chemically synthesized by reduction with hydrazine and those produced electrolysis from the basic (nitrate) complex (ammonium) electrolytes were examined X-ray diffraction (XRD) scanning electron microscopic (SEM) analysis of particles. Morphologies obtained particles very different at macro level. The needle-like dendrites, as well mixture irregular regular crystals, formed nitrate electrolyte, while highly-branched pine-like dendrites clearly noticeable spherical grains...
Hydroxyapatite attracts great attention as hard tissues implant material for bones and teeth. Its application in reconstructive medicine depends on its biocompatibility, which is a function of composition surface properties. The insertion protein element the implants can improve cell adhesion osseointegration. Having this mind, proposal work was to develop L-alanine-grafted hydroxyapatite nanoparticles study their biocompatibility. Two L-alanine sources three grafting methods were used...
Anodic oxidation of the natural mineral chalcopyrite from Bor ore deposit has been studied by cyclic voltammetry in pure sulfuric acid solutions. At obtained voltammograms, appearance peaks at certain potential regions was identified and found to be much less pronounced than those previously reported literature. The voltammetric kinetic analysis confirmed that two-electron exchange electrochemical reactions occur. explanation for this somewhat different behavior compared concentrates widely...
Y0.8−xGdxF3:Yb/Er mesocrystals with a biocompatible surface and diverse morphological characteristics were successfully synthesized using chitosan-assisted solvothermal processing. Their structural properties, studied X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning transmission electron microscopy energy dispersive analysis, further correlated the up-conversion emission (λexc = 976 nm) recorded in function of temperature. Based on change visible green emissions...
The influence of the presence Sb atoms, as foreign metal atoms in anode copper, on kinetics, and, mechanism anodic dissolution and cathodic deposition copper acidic sulfate solution has been investigated. galvanostatic single-pulse method used. Results indicate that increase exchange current density determined from Tafel analysis electrode reaction. It is attributed to crystal lattice parameter XRD material.
Abstract Single phase β‐NaY 0.8‐ x Gd Yb 0.18 Er 0.02 F 4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP‐assisted solvothermal treating at 200°C (PVP‐ polyvinylpyrrolidone). With the increase in 3+ concentration, size decreased. The up‐converting spectra recorded upon 980 nm irradiation showed green (510‐560 nm) and red (640‐690 emissions, due to 2 H 11/2 , S 3/2 → I 15/2 9/2 transitions, respectively. strongest up‐conversion luminescence was detected 15...
Mechanically activated strontium titanate (SrTiO3) powders with various iron (III)oxide (Fe2O3) doping levels (1.5, 3, and 6 wt%) were prepared by solid state method. Due to the possibility of ion incorporation in SrTiO3 onto Sr2+ and/or Ti4+ sites a detailed analysis influence dopants on microstructure, morphology, optical properties photocatalytic activity was conducted. The XRD showed that incorporated into lattice particles. In case lower concentration dopant (1.5 wt%), there significant...
Amorphous iron (III) oxide was obtained from clay, using ammonium hydroxide as a precipitating agent. Influence of freeze drying under vacuum, method, on particle size, chemical composition, and crystallinity powder investigated. After drying, precipitate annealed in air at 500?C 900?C. X-ray diffraction, size analysis, scanning electron microscopy, energy dispersive spectrometry, Fourier transform infrared spectroscopy, thermogravimetric differential thermal analysis were used to...
