Stable silver nanoparticles were successfully synthesized by chemical reduction of silver nitrate in ionic liquids 1Ethyl-3-methylimidazolium tetrafluoroborate [Emim] BF4 and 1Ethyl-3-methylimidazolium hexafluorophosphate [Emim] PF6 at room temperature. The characterization of the silver nanoparticles such as their size and shape was performed by X-ray Diffraction (XRD) and Scanning Electron Mi...

deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the finaltempering treatment to enhance the wear resistance and hardness of the steels. in this study, the effects of thedeep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studiedusing the wear testing machine and polarization and impedance...

In this study, the Er:YAlO3 as up-conversion luminescence agent, which can transfer the visible light part in the sonoluminescence to ultraviolet light, was synthesized by nitrate–citrate acid and sol–gel method. And then the Er:YAlO3/TiO2–Fe2O3 composite as a sonocatalyst was prepared by ultrasonic dispersion and liquids boil method. The prepared Er:YAlO3/TiO2–Fe2O3 composite was characterized...

We have been prepared Semiconducting oxide material like TiO2, SiO2, TiO2-SiO2 and TiO2/SiO2 thin films for taken different composition by using hydrothermal method. All these elements were deposited on the glass substrate. In this films are acted on the p and n type working with the majority carrier are recombination of electron and hole .This material is N type but it will acted p-type Ti and...

GaN was grown on porous silicon (PS) substrates by Metalorganic Vapour Phase Epitaxy at temperature of 1050 8C. An additional AlN buffer layer is used between GaN and PS. The crystalline quality and surface morphology of GaN films were studied by X-ray diffraction and scanning electron microscope (SEM), respectively. Preferential growth of hexagonal GaN with h00.1i direction is observed and is ...

This chapter focuses on the recent development and optimization of analytical electron microscopy to understand the dynamic changes in the bulk and interfaces of electrodes and electrolytes within all solidstate batteries. Three major aspects are covered: (1) design and fabrication of all solid-state batteries that remain functional after careful focused ion beam (FIB) processing; (2) enablemen...

A new type of chain-like Si@SiSe(2) nanowire heterostructures has been successfully synthesized via a one-step Au-catalyzed chemical vapor deposition (CVD) route. The composition and microstructure of the achieved structures were investigated by scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscope (TEM) and micro-Raman spectroscopy. Op...

Nanorods hydroxyapatite, (HAP) Ca(10)(PO(4))(6)(OH)(2) is successfully prepared by water in oil microemulsion using, CaCL(2) and H(3)PO(4) (water phase), poly(sodium 4-styrene sulfonate) (PSSS) as template and cyclohexane as oil phase. The nano-structure of the product was studied by means of X-ray diffraction (XRD), Fourier transmission infrared spectrometer (FT-IR), scanning electron microsco...

Pb(Zr0.52Ti0.48)O3 (PZT) nanotubes with diameters of 80–100 nm and a wall thickness of 15–20 nm were prepared by sol–gel template technique and using multi-walled carbon nanotubes (MWCNT) as sacrificial templates. The coating process of MWCNT with PZT precursor sol and removal of the carbon nanotubes by an interrupt heat treatment were discussed and studied by Raman spectroscopy. Simultaneous t...

In this work, nanostructured Mg-Al-Nd alloys were successfully fabricated using mechanical alloying method. Phase structures of the milled powders and the extruded rods were examined using X-ray diffraction (XRD) and the microstructures were observed using a transmission electron microscope (TEM). The element distributions were also examined by an energy dispersive spectroscopy (EDS) system. Th...
