in this paper, cuo nanoparticles  have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and 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...

“Nanomischief” is reviewed in hopes of helping our fellow “nanomachinists.” Scanning electron microscopy (SEM) and optical microscope images are shown, along with a short narrative of the problems encountered and their solutions.

in this article vanadium boride nanopowder was synthesized by mechanochemical reduction method in a high-energy ball mill. the synthesized powders were studied by x-ray diffraction (xrd), scanning electron microscopy (sem), xray map and transmission electron microscopy (tem). according to x-ray diffraction the product predominantly consists of vb phases after 100 min milling without further hea...

in this paper, nano fibers (engelhard corporation titanosilicate number 10 / polyacrylonitrile) ets-10 / pan, as a composite exchanger to absorb heavy metals, were synthesized and optimized. several parameters were affected on this absorption. results show that the optimization sizes of the nano fibers are about 75 nanometers. structures were analyzed by scanning electron microscope (sem) and e...

Electron microscopes have been widely used to investigate cell structures under high resolution. A scanning electron microscope (SEM) provides tridimensional images of a cell surface, while a transmission electron microscope (TEM) is commonly employed to observe the internal structure changes of host cells after bacterial adherence and invasion. The SEM and TEM can reveal bacterial location, bi...

This study was performed to recognize the loess texture in Golestan Province, Iran using the microstructure analysis according to the electron microscopic images. Loess microstructure study allows for investigating the characteristics of particle shape, fabric, cement and porosity in microscopic images. In recent years, computer analysis has been replaced with manual calculation due to its high...
