Traditional approaches to the formation of mesostructured inorganic films from block-copolymer and surfactant templates rely on simultaneous assembly of amphiphilic structure-directing agents and inorganic sol–gel precursor species into ordered hybrid structures. Variations in sample composition and processing conditions have afforded considerable control over the local (nanometer-scale) morpho...

an experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (se) sources on broiler male birds (ross 308). uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental se, negative control), 0.25 ppm of inorganic se, 0.5 ppm of inorganic se, 0.25 ppm of inorganic se + 0.25 ppm of organic ...

a risk assessment study was conducted to predict the expected hazardous influence on the ecosystem resulted from urbanization and industrialization activities at helwan area, egypt. to achieve these goals, soils, plants and water samples were collected from helwan area, and their total concentrations of inorganic contaminants (cd, cr, co, cu, fe, mn, ni, pb, and zn) and organic pollutants; such...

Today, the building and construction sector demands environmentally friendly sustainable protective coatings using inorganic coating materials for safe, non-hazardous, great performance. Many researchers have been working on solutions to protect concrete metal infrastructures against corrosion surface deterioration with intention of introducing green alternatives conventional coatings. This art...

New carbon forms exhibiting extraordinary physico-chemical properties can be generated from nanostructured precursors under extreme pressure. Nevertheless, synthesis of such fascinating materials is often not well understood that results, as the case C60 precursor, in irreproducibility results and impeding further progress design. Here semiconducting amorphous having bandgaps 0.1-0.3 eV advanta...

Abstract Alkali-activated systems belong to the group of alternative inorganic binders in which binder properties are dictated by both aluminosilicate precursor and alkaline activator. In this work, blast furnace slag three different activators, namely sodium hydroxide, water glass, carbonate, were selected. An innovative mixture design based on same concentration alkali (Na + ) 4 mol/dm 3 for ...
