In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...

(y)Ni0.7Co0.3Fe2O4 + (1-y) Ba0.7Pb0.3TiO3 composites were prepared using ceramic method. The phase analysis was carried out by X-ray diffraction technique. It has confirmed that no impurity phase is present in the composites. The dc resistivity, thermo emf studied as a function of temperature. The value of static magnetoelectric conversion factor, i.e. dc (ME)H studied as a function of magnetic...

resistance spot welding is an important manufacturing process in the automotive industry for assembling bodies. the quality and strength of the welds and, by extension, the body is mainly defined by the quality of the weld nuggets. the most effective parameters in this process are sheet material, geometry of electrodes, electrode force, current intensity, welding time and sheet thickness. the p...

Chemical and physical transformations by milling are attracting enormous interest for their ability to access new materials and clean reactivity, and are central to a number of core industries, from mineral processing to pharmaceutical manufacturing. While continuous mechanical stress during milling is thought to create an environment supporting nonconventional reactivity and exotic intermediat...

In this study, Flake-like magnesium hydroxide (Mg(OH)2) and cubic-like aluminum hydroxide (Al(OH)3) nanostructures were synthesized via a simple co-precipitation method at relatively low temperature. Chemical properties and surface morphology of the magnesium hydroxide and aluminum hydroxide were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy image (SEM), transm...

Polylactic acid (PLA) is the most wide-scale investigated biodegradable and renewable under specific processing conditions thermoplastic polyester. As bioplastic material, it has potential to be used as a substituent of conventional polymers derived from fossil fuel resources. The drawbacks possessed by PLA poor thermal electrical properties, mechanical brittleness, ability undergo polymer chai...

Zirconium tungstate as an inorganic ion exchange material has been synthesized at different conditions. The materials were characterized by means infrared spectroscopy, thermo gravimetric analysis, and X-ray diffraction techniques. The stability of the ion exchangers was investigated in acidic and alkaline media. Ion exchange properties of synthesized materials were studied by measuring the dis...

objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...

A bone has a hierarchical structure as shown in Fig. 1 [1]. Macroscopic bone properties are dependent on the microstructure and properties of structural elements. The bone is a composite material that consists of hydroxyapatite particles in a matrix of collagen fiber. Borsato et al. [2] measured the strain of hydroxyapatite by X-ray diffraction and obtained clear evidence of the stress concentr...
