AN INVESTIGATION ON REACTIVE SINTERING OF NANO-CRYSTALLINE TiO2 -Al POWDER PREPARED BY MECHANICAL ALLOYING
In this research an ultra-fine grained composite structure consisting of an intermetallic matrix together with dispersed nano-sized Al2O3 obtained via mechanical activation of TiO2 and Al in a high energy ball mill and sintering of consolidated samples. Phase composition and morphology of the milled and sintered samples were evaluated by XRD and SEM techniques Thermal behavior of the powder sa...
متن کاملNano/Micro-Patterning of Semiconductors by Site Selective Chemical Etching Using Noble Metals as Catalyst
Controlled silicon structures on the micron to nanometer order have received much attention owing to their potential applications in various fields such as electrochemical, optoelectrical, and biological sciences. Although the techniques commonly used in fabricating nano-/microstructured silicon are conventional lithographic techniques using a resist mask with an optical, electron, or X-ray bea...
متن کاملPoly (Butylene Succinate) Scaffolds Prepared by Leaching
Biomaterials are the main focuses of scientists’ efforts to develop new materials to replace or repair bone tissues [1]. Biomaterials are natural or synthetic materials which can interface with biological systems allowing the increase, repair or even the replacement of tissues and organs of the human body [2]. Within biomaterials, the polymers can be natural or synthetic as well. The main polym...
متن کاملSynthesis and catalytic properties of nano CuO prepared by soft chemical method
Well faceted CuO nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. A possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by FT-IR study. The large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...
متن کاملEffect of various fuels on structure and photo-catalytic activity of TiO2 nano-crystalline prepared by microwave-assisted combustion method
Nano-crystalline TiO2 were synthesized by combustion method using metal nitrate solution and urea, glycin and citric acid fuels. Microwave irradiation was used as heating source. X-ray diffraction, scanning electron microscope as well as Fourier transform infrared spectroscopy were performed to characterize the obtained samples. X-ray diffraction patterns revealed that in the case of citric aci...
