Anticorrosion Behavior of the SiO2/Epoxy Nanocomposite-Concrete Lining System under H2SO4 Acid Aqueous Environment

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Thermodynamics of the formation of sulfuric acid dimers in the binary (H2SO4–H2O) and ternary (H2SO4–H2O–NH3) system

Sulfuric acid is an important gas influencing atmospheric new particle formation (NPF). Both the binary (H2SO4–H2O) system and the ternary system involving ammonia (H2SO4–H2O–NH3)may be important in the free troposphere. An essential step in the nucleation of aerosol particles from gas-phase precursors is the formation of a dimer, so an understanding of the thermodynamics of dimer formation ove...

Photocatalytic Removal of Acid Blue 113 Dye from Aqueous Solutions Using Zinc Oxide-Kaolin Nanocomposite under Visible Light Irradiation

Background and purpose: Textile industries produce huge amounts of colored wastewater. Synthetic dyes cause serious problems to human health and aquatic organisms due to their toxic and carcinogenic properties. In this study, Acid Blue 113 (AB113), which is stable and persistent against conventional treatment methods was selected as the target contaminant. Materials and methods: The synthesis ...
