abstract background and purpose:the rapid urbanization and industrialization in many parts of the world have led to the accumulation of heavy metals in the terrestrial environment and pose a serious threat to human health. in this study, a broad assessment was conducted to estimate the levels of heavy metals in groundwater in sistan and baluchestan via geographic information system (gis), iran,...

The effect of aluminum (0, 2, 4, and 6 wt. %) copper on graphite morphology, microstructure compressive behavior ductile iron specimens manufactured by sand casting technique were investigated. morphology evaluated using optical microscopy (OM) scanning electron (SEM) equipped image processing software. To study the mechanical properties, compression test was conducted specimens. results indica...

Rechargeable aluminum-graphite batteries using chloroaluminate-containing electrolytes have been the focus of significant research, particularly due to their high-rate capabilities. Engineered graphite electrodes shown exhibit supercapacitor-like rate performance, despite fact they store charge via electrochemical intercalation polyatomic AlCl 4 ? anions. However, origins such capabilities are ...

abstract        background and objective: aluminum salts are among the most common useful additive compounds in preparation of human and animal vaccines. aluminum phosphate and aluminum hydroxide are two additives that show good immunoadjuvant effects with many antigens. aluminum-containing vaccines lead to a better and longer immune response compared to adjuvant-lacking vaccines. the chromogen...

Graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. Structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (LDA). Band structures and density of states for the propose carbon 3D models are reported. A finite energy gap and...
