We present a spectral variability study of a sample of about 25 bright blazars, based on optical spectroscopy. Observations cover the period from the end of 2008 to mid 2015, with an approximately monthly cadence. Emission lines have been identified and m... see more

The SO2 is one of the volcanic gases that can use as indicator of volcano activity. Commonly, SO2 emission is measured by COSPEC (Correlation Spectroscopy). This equipment has several disadvantages; such as heavy, big in size, difficulty in finding spare ... see more

The dynamics of the expanding plasma produced by excimer laser ablation of different materials such as silicon, silicon carbide, graphite and tin powder were studied by means of time integrated, spatially resolved emission spectroscopy and fast photograph... see more

Plasma electrolytic oxidation (PEO) process of Al–Zn–Si alloy in water solution containing 4 g L-1 sodium metasilicate at constant current den­sity of 400 mA cm-2 was investigated. The species present in PEO micro- -discharges and their ionization stages ... see more

Atmospheric pressure plasma jet (APPJ) technology is a versatile technology that has been applied in many energy harvesting and storage devices. This feature article provides an overview of the advances in APPJ technology and its application to solar cell... see more

The object of research is studying Raman scattering technique, photoluminescence and some optical properties of silver nanoparticles created by eco-friendly technique which independent on a long time, effort, energy and high temperatures, and with the hig... see more

A spectroscope presents the optical emission spectroscopy (OES) technique on laser-produced copper and silver plasmas. The optical emission spectrum technique was used to analyzes the spectrum arising from the Cu, Ag Laser Nd: YAG plasmas with a wavelengt... see more
