AB  - ZnO represent one of the most important multifunctional materials. Its properties are well known and confirmed in different application areas such as: gas sensors, UV lasers, solar cells, electroluminescent and optoelectronic devices, piezoelectric transducers, hydrogen-storages, rubber industry and plastic processing, cosmetics and pharmacy, and it is also used as an antibacterial agent. In this work, we propose a low-temperature hydrothermal method for the synthesis of phase-pure ZnO powders with a controlled morphology and narrow particle size distribution. This simple and low-cost method allows tailoring of the shape and size of ZnO particles, from micro-rods via hexagonal prism-like to nano-spheres, by choosing the appropriate pH of the reaction solution, tuned by the varying of [Na+]:[Zn2+] molar ratio. The agglomeration of the powders was prevented with the assistance of PVP as a capping agent. The synthesized powders were characterized by XRD, TEM, SEAD and HRTEM methods to examine the phase purity and crystallinity. FE-SEM measurements were used for the morphology characterization, while the results of Raman and UV-Vis DRS measurements were used for the study of optical properties. The relationship between the particle size and morphology and the optical properties is discussed. Diffuse reflectance spectra of ZnO powders with different size and morphology revealed characteristic R curves with the absorption edge near 380 nm, but with obvious difference in the absorption in the visible region. The micro-sized powder ZnO8 revealed the lowest reflectance (∼70%), compared to submicro- (∼80%) and nano-sized (ZnO12 and ZnO13, ∼90%) powders. Thus, the reflectance of the ZnO powders decreases with the increase in the average particle size.

AB  - We report unusual sintering behavior of Ca-deficient hydroxyapatite processed with different heating rates; particularly, faster heating resulted in higher densification. We hypothesize that faster heating delays formation of β-tricalcium phosphate which yields to unobstructed densification in intermediate sintering stage, allowing further tailoring of both microstructure and phase composition (hydroxyapatite/tricalcium phosphate).

AB  - In this paper, we investigate the effect of the particle size and morphology on the optical properties of ZnO. A series of ZnO micro and nanocrystals were synthesized by the hydrothermal processing of zinc acetate dihydrate and sodium hydroxide as the starting materials, and polyvinylpyrrolidone (PVP) as the polymer surfactant. The particle size and morphology were tailored by adjusting the reactant molar ratios [Zn2+]/[OH−], while the reaction temperature and the time remained unchanged. X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and high-resolution TEM (HRTEM) have shown that the micro and nanocrystals have a high crystalline pure wurtzite-type hexagonal structure with nanosized crystallites. The size and morphology of the ZnO micro and nanocrystals were investigated by field emission scanning electron microscopy (FE-SEM), which showed a modification from micro-rods via hexagonal-faceted prismatic morphology to nanospheres, caused by simple adjustment of the reactant molar ratio [Zn2+]/[OH−] from 1:1 to 1:5. The optical properties of the ZnO micro and nanocrystals, as well as their dependence on the particle size and morphology were investigated by Raman and ultraviolet–visible (UV–vis) diffuse reflectance spectroscopy (DRS). The UV–vis spectra showed that the modification of the particle size and morphology from nanospheres to micro-rods resulted in increased absorption, and a slight red-shift of the absorption edge (0.06 eV). Besides, the band gap energy of the synthesized ZnO micro and nanocrystals showed the red shift (∼0.20 eV) compared to bulk ZnO. According to the results of a Raman spectroscopy, the enhanced visible light absorption of the ZnO micro and nanocrystals is related to two phenomena: (1) the existence of lattice defects (oxygen vacancies and zinc interstitials), and (2) the particle surface sensitization by PVP.

AB  - It is well known that selenium is an essential trace element playing the important roles in mammalian biology. For years, its organic forms and some salts have been used in studying its biological effects, but recently, selenium nanoparticles have gained great attention as a possible material for cancer therapy and prevention. In this study we report the facile and reproducible method for synthesis the nanoselenium by reduction of sodium selenite with an ascorbic acid, in the presence of a two stabilizing agents, bovine serum albumin (BSA) or poly (L-glutamic acid) (PGA). The influence of the sodium selenite/ascorbic acid ratio as well as the types and concentration of two different stabilizers on the wide variety physicochemical characteristics of obtained particles were examined.

AB  - Phase composition, crystal structure and morphology of biological hydroxyapatite (BHAp) extracted from human mandible bone, and carbonated hydroxyapatite (CHAp), synthesized by the chemical precipitation method, were studied by x-ray powder diffraction (XRD), Fourier transform infrared (FTIR) and Raman (R) spectroscopy techniques, combined with transmission electron microscopy (TEM). Structural and microstructural parameters were determined through Rietveld refinement of recorded XRD data, performed using the FullProf computing program, and TEM. Microstructural analysis shows anisotropic extension along the [0 0 l] crystallographic direction (i.e. elongated crystallites shape) of both investigated samples. The average crystallite sizes of 10 and 8 nm were estimated for BHAp and CHAp, respectively. The FTIR and R spectroscopy studies show that carbonate ions substitute both phosphate and hydroxyl ions in the crystal structure of BHAp as well as in CHAp, indicating that both of them are mixed AB-type of CHAp. The thermal behaviour and carbonate content were analysed using thermogravimetric and differential thermal analysis. The carbonate content of about 1 wt.% and phase transition, at near 790 °C, from HAp to β-tricalcium phosphate were determined in both samples. The quality of synthesized CHAp powder, particularly, the particle size distribution and uniformity of morphology, was analysed by a particle size analyser based on laser diffraction and field emission scanning electron microscopy, respectively. These data were used to discuss similarity between natural and synthetic CHAp. Good correlation between the unit cell parameters, average crystallite size, morphology, carbonate content and crystallographic positions of carbonate ions in natural and synthetic HAp samples was found.
