Air quality in greater Algiers, in Algeria was assessed analyzing aerosol particulate matter (PM10 and PM2.5) at a site influenced by heavy road traffic. Particulate matters were collected using a Gent sampler to characterize the atmospheric aerosol of Algiers. An Energy dispersive X ray spectrometer (EDXRF) was used to determine the heavy metal concentrations in the PM2.5 and PM10 size fractio...

Abstract Cobalt and molybdenum are valuable metals whose presence in nature is very limited. The consumed catalyst, which abundantly available the petroleum refinery industry, a potential source of those metals. A hydrometallurgical process using acid as leaching agent usually used to extract separate more effectively. This method considered capable yielding recovery higher percentage metal. In...

A fragment of the NWA 2975 Martian meteorite, an enriched basaltic shergottite, was analysed to complete its geochemical characterisation performed 10 years ago. By this means, feasibility employed techniques in a combined way for present and future space exploration missions can be tested. For aim, Raman spectroscopy used supported by micro energy dispersive X-ray fluorescence (μ-EDXRF) laser-...

The goal of this research is to characterize selected silica-rich solid wastes for potential use as silica source. two prominent chosen study are waste container soda-lime glasses and rice husks (agro-waste), both which known be wastes. Rice husk ashes (RHAs) were produced by thermally treating husks, while soda-lime-silica (WSLSG) crushed milled produce glass powder. EDXRF was used examine the...

The present study sought to expand on and confirm the already available information painting materials used by Venetian artist Guido Cadorin (1892–1976). A multi-analytical approach was employed in of six tempera grassa easel paintings one casein a panel signed belonging International Gallery Modern Art Ca’ Pesaro Venice, Italy, which dated from 1921 1951. aim research identify materials, obser...
