Nickel films of 300 nm thickness were deposited by electron beam evaporation at room temperature on 316 stainless steels. Corrosion studies of Ni coated 316 SS have been performed after N+ ion implantation at different energies of 20, 40, 60 and 80 keV. The structure and surface morphology of the films were evaluated using X-ray diffraction (XRD), atomic force microscope (AFM) an...

Adiabatic shear banding during high speed machining is important to understand material removal mechanisms. This paper investigates the microstructure of adiabatic shear bands (ASBs) in the serrated chips produced during the high speed machining of AISI 1045 hardened steel. Optical microscope, scanning electronic microscope(SEM) and transmission electronic microscope(TEM) were used to explore t...

The electrical conduction phenomena, dielectric response and microstructure have been discussed in sintered silicon nitride ceramics at different temperature and frequencies. Microstructure and phase of the sintered samples was investigated by Scanning Electron Microscope (SEM) and X-ray diffractometer (XRD). The electrical conductivity, dielectric constant and dielectric loss increases exponen...

Mesoporous, micro/nanosized TiO2/C composites with uniformly dispersed TiO2 nanoparticles embedded in a carbon matrix have been rationally designed and synthesized. In brief, TiO2 precursor was infiltrated into the channels of surface-oxidized mesoporous carbon (CMK-3) by means of electrostatic interaction, followed by in situ hydrolysis and growth of TiO2 nanocrystallites, resulting in ultrafi...

This paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using Persian mesquite grain. Several techniques and methodologies such as, proximate analysis, N2 adsorption–desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT-IR), X-ray Diffraction (XRD), X-ray photoe...

In this study, multifunctional Fe₃O₄@SiO₂@GdVO₄:Dy3+ nanocomposites were successfully synthesized via a two-step method. Their structure, luminescence and magnetic properties were characterized by X-ray diffraction (XRD), scanning electronic microscope (SEM), transmission electron microscopy (TEM), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM). The results indicated tha...

Metal oxide nanomaterials are important and excellent materials, because of its special properties like chemical stability, high photo catalytic activity, high electric permittivity, non-toxic nature. So it is used in various applications like optical, electrical, electronic, antiseptic, antibacterial, environmental, semi conductors and catalytic devices. Present work focused on to synthesis of...
