The Ultraviolet and VIsible Spectrometer (UVIS), covering the 200–650 ​nm range, is one of three spectrometers that comprise NOMAD instrument on ExoMars 2016 Trace Gas Orbiter (TGO). UVIS can operate in solar occultation, nadir limb viewing mode was designed to monitor ozone aerosols Martian atmosphere. Here, we describe calibration procedure convert raw data into a calibrated product ready for...

Exoplanet discoveries since the mid-1990's have revealed an astounding diversity of planetary systems. Studying these systems is essential to understanding formation processes, as well development life in universe. Unfortunately, humanity can only observe limited aspects exoplanetary by telescope, and significant distances between stars presents a barrier situ exploration. In this study, we pro...

copper vanadate nanostructures were prepared via ex-situ precipitation approach in presence of schiff-base ligand (n,n׳ -buthylenebis(acetylacetone iminato)dianion = acacbn) as a new capping agent. the effect of different cu sources and ph on the size, morphology and size distribution of copper vanadate nanostructures was investigated. the as-prepared products were characterized using x-ray dif...

Sub-micrometer-sized CdS spheres were synthesized by hydrothermal and solvothermal reactions using Cd(NO3)2.4H2O and CH4N2S raw materials at a constant stoichiometric 1 : 2, Cd : S molar ratio. Various conditions such as solvent type (water and/or ethanol), reaction time and temperature were examined for the synthesis of the targets. The sy...

The use of plant extract is generating interest of researchers toward cost effective and eco-friendly green synthesis of nanoparticles. In the present work, Cupric oxide nanoparticles were synthesized using coffee powder extracts by the sol-gel method at different calcination temperatures. The synthesized nanoparticles were characterized by X-ray diffraction, scanning electron microscopy , ultr...
