Single crystalline BaTiO3 (BT) was prepared using TiCl4, BaCl2 and oxalic acid. The structure of the prepared nanocrystalline BT powders were a tetragonal perovskite according to XRD and HRTEM analysis. Annealing powder to 750C show that pure BT phase was formed according to XRD, TG, and FTIR spectroscopy. The TEM images of the prepared powder reveal spherical morphology of BT, while a finger t...

Fingerprint development has been used to visualize latent prints since the 19th century, and several companies produce a variety of commercially available black fingerprint powders. While method develop fingerprints refined over years, composition powders that are in print not studied extensively. Six different were using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM...

Porous (pr-)SnO2-based powders were synthesized by ultrasonic spray pyrolysis employing home-made polymethylmethacrylate (PMMA) microspheres (typical particle size: 70 nm in diameter), and effects of the CuxO addition to pr-SnO2 powder on acetone toluene sensing properties investigated. Well-developed spherical pores reflecting morphology PMMA microsphere templates formed SnO2-based powders, wh...

The particle shape influences the part properties in laser powder bed fusion, and flowability layer density (PLD) are considered link between properties. Therefore, this study investigates relationship these their influence on final for six 1.4404 (316L) powders eight AlSi10Mg powders. results show a correlation of with Pearson coefficient (PCC) ?0.89 PLD Hausner ratio, PCC ?0.67 ratio circular...

in this research, synthesis and characterization of silver/alumina composite powders was investigated. this kind of metal/ceramic composite powders is used for fabrication of cutting tools inserts. the role of silver is toughening the final product. the powders were synthesized via co-precipitation method. the composition of the synthesized powders was ag/80% wt 〖al〗_2 o_3. silver nitrate, alum...

Two plant-based emulsifiers, soybean lecithin and pea protein isolate, were studied for their emulsifying encapsulating capacities of an antimicrobial molecule, trans-cinnamaldehyde (TC), at two different pH values, three seven, after drying with techniques, spray-drying freeze-drying. To characterize the obtained capsules, various physicochemical tests conducted to examine particle size, encap...

Background: Bioactive glasses 58S, are silicate-based materials containing calcium and phosphate, which dissolved in body fluid and bond to the bone tissue. This type of bioactive glass is highly biocompatible and has a wide range of clinical applications. Methods: The 58S glass powders were synthesized via sol-gel methods, using tetraethyl orthosilicate, triethyl phosphate, and calcium nitrate...

Abstract: Nanocrystalline MgAl2O4 spinel powder was synthesized using metal nitrates and a polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). According to XRD res...
