The spectral imagings were performed in order to examine the lateral resolution of the EDX analysis which is attached in an ultra low acceleration voltage SEM. The spectral imagings were performed for the cross section of the Ni coating on Al, which was cut using microtome, and the cross section of GaAs/AlAs super-lattice, which was cleavaged, using a ultra-low-acceleration-voltage SEM and EDX....

The influence of pretreatment of AAO template and deposition process on magnetic NiCoFe nanowire fabricated by electroless method was investigated. The Electroless process carried out at room temperature using DMAB as a reductant agent. SEM and EDX analysis used to characterize the deposited sample. According to the results, sonication during deposition process is not recommended in fabrication...

Thermodynamic analysis and characterization of the investigated Ga-Ge-Sb alloys, which is of a practical importance in electric semiconductors industry, are presented in this paper. Thermodynamic analysis are done by the used of experimental investigation technique of Oelsen calorimetry and different thermal analysis (DTA) and thermodynamic predicting methods, while characterizations are done b...

the perovskite-type oxides strontium-substituted lanthanum nickelate (lsno) were prepared by a coprecipitation method in the present of octanoic acid as surfactant. the phase composition, morphology,lattice parameters and size of nanoparticles in these materials were characterized through fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microscopy (sem...

The paper focuses on corrosion phenomena involving copper, corrosive sulphur and solid insulation of oil-immersed transformers. A study of the available mitigation technique such as passivation to reduce the effects of corrosion phenomena is carried out with the commercially available passivator, Irgamet 39 (Toluiltriazole dialkylamine) (ciba), with concentration of 100 ppm. The paper insulated...

Lapis lazuli has been used for more than 7000 years for the manufacture of precious objects and jewels. The main quarries for this stone are still active in Afghanistan, but there are other quarries that could have been exploited since antiquity in the Pamir mountains (Tajikistan), in Pakistan and in Siberia. For this reason a provenance study of lapis lazuli could provide answers to some impor...
