A composite Cd 0.95 Ni 0.05 Sb crystal consisting of CdSb and NiSb inclusions was obtained by the modified Bridgman method. It shown methods scanning electron microscopy, X-ray phase analysis, energy-dispersive spectroscopy, studies Raman spectra, that main matrix a block single (orthorhombic Pbca structure) containing microcrystalline acicular second (hexagonal structure NiAs type P6 3 /mmc). ...

A novel method that enables single-crystal diffraction data to be obtained from a powder sample is presented. A suspension of LiCoPO(4) microrods was subjected to a frequency-modulated dynamic elliptical magnetic field to align the microrods; the alignment achieved was consolidated by photopolymerization of the suspending UV-curable monomer. The composite thus obtained (referred to as a pseudo ...

For inquiry of application of ultrasonic method [UT] possibilities at composite materials inspection specimens based on the carbon fibres that correspond to structure aircraft elements were designed and made. Applied specimens were made of different composite materials with various numbers of layers and various thicknesses. For simulation of delaminating in different layers of tested structure ...

Nano hexagonal wurtzite ZnO has been prepared on zeoliteA by the sono-chemical method. The zeoliteA was mixed into Zinc gel, after stirring for two days, the mixture was irradiated 30 min by ultrasonic probe. The filtrated composite gel was calcinated at 500°C for 3h in furnace. The produced composite was characterized using X-ray diffraction, FT-IR spectroscopy and field emission scanning elec...

The composite powders of barium-magnesium ferrite were prepared using sol-gel auto-combustion and microwave methods. The crystal structure and the shape of nanocomposites have been compared. X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Vibrating Sample Magnetometer (VSM) were used to investigate the structural, morphological and magnetic properties of nanopowder. The formatio...

Using Y molecular sieve as the core, Y/SBA-15 composite molecular sieves were prepared by different crystallization methods in the paper. The growth process and morphologies of the composite molecular sieves were controlled by adjusting the synthesis factors. The structures and acidity of two kinds of composite molecular sieves were characterized by X-ray diffraction (XRD), N2 adsorption/desorp...

objective(s): the current study reports the production and biocompatibility evaluation of a ternary nanocomposite consisting of ha, pla, and gelatin for biomedical application.materials and methods: hydroxyapatite nanopowder (ha: ca10(po4)6(oh)2) was produced by burning the bovine cortical bone within the temperature range of 350-450 oc followed by heating in an oven at 800. synthesis of the te...

Biominerals are invariably composite materials, where occlusion of organic macromolecules within single crystals can significantly modify their properties. In this article, we take inspiration from this biogenic strategy to generate composite crystals in which magnetite (Fe3O4) and zincite (ZnO) nanoparticles are embedded within a calcite single crystal host, thereby endowing it with new magnet...
