in this essay, jelinki pottery (clinky- ware ceramics) has been studied as one types of ceramics at arsacides era. raw materials, quality of processing and baking conditions of potteries are some of effective factors in strength and stability of this material. employing purposeful methods of chemical analyses in order to examine such factors and in fact structural science of historical potterie...
According to the increasing development of the mankind, social and technology activities in the earth, various industry is in a state of uncontrolled growth. In the present study, magnetite/nickel oxide mixed metal oxide nanoparticles (FNMMO NPs) were prepared by a simple method assisted by ultrasonic waves and applied as a novel adsorbent to dispose of dye wastewater. The morphology and chemic...
در این پژوهش نحوه ساخت نانوکامپوزییت eva/ag و اثر ضد میکروبی آن در درصدهای مختلف نانو ذره نقره مورد بررسی قرار گرفته است.نانوکامپوزیت حاصل از نطر شکل شناختی ، اندازه ذرات، ساختمان شیمیایی ، با استفاده از تستهای sem(scanning electrou microscopy)،tem (transmission electron microscope) ، xrd (x-ray fluorescence spectroscopy) ،ftir (fourier transform infrared spectroscopy) مورد ارزیابی قرار گرفت. د...
In this study, we have developed a sensitive and selective glucose sensor using novel CuO nanosheets which were grown on a gold coated glass substrate by a low temperature growth method. X-ray differaction (XRD) and scanning electron microscopy (SEM) techniques were used for the structural characterization of CuO nanostructures. CuO nanosheets are highly dense, uniform, and exhibited good cryst...
a simple method has been employed to synthesize copper and copper oxide nanoparticles from copper (ii) succinate precursor by thermal decomposition method using oleylamine as a capping agent. the particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from x-ray diffraction (xrd). the synthesized copper nanoparticles were characterized by uv-visib...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
Phase Identification in a Scanning Electron Microscope Using Backscattered Electron Kikuchi Patterns
Backscattered electron Kikuchi patterns (BEKP) suitable for crystallographic phase analysis can be collected in the scanning electron microscope (SEM) with a newly developed charge coupled device (CCD) based detector. Crystallographic phase identification using BEKP in the SEM is unique in that it permits high magnification images and BEKPs to be collected from a bulk specimen. The combination ...
