Alkali-activated slag is commonly used as a cement substitute to reduce the environmental footprint of construction materials. Nonetheless, use significant amount alkaline activators, such sodium silicate or hydroxide, can be detrimental in terms global warming potential impact. The aim this work complementary activators partial replacement and therefore activated binder. Calcium calcium carbon...

The selective catalytic reduction for reducing NOx with NH3 (NH3-SCR) has been widespread used in denitration. Considering the shortcomings of vanadium-based catalysts, a series novel CeO2-SnO2 composite oxide catalysts good SO2 tolerance were developed. effects preparation methods on performance had systematically studied by characterization methods, such as XRD, SEM, N2 adsorption–desorption,...

almcm-41 was applied for adsorption of methylene blue (mb) and auramine (au) in single and binary component systems. in the single component systems, almcm-41 represents higher adsorption capacity for mb than au with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚c for mb and au, respectively. in the binary component system, mb and au exhibit competitive adsorption onto...

in this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing n,n-dimethyl acetamide (dmac) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 k. the results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. deviation values of heavy alcohol have more positive and less negative excess...

‎let $g$ be a graph with vertex set $v(g)$ and edge set $x(g)$ and consider the set $a={0,1}$‎. ‎a mapping $l:v(g)longrightarrow a$ is called binary vertex labeling of $g$ and $l(v)$ is called the label of the vertex $v$ under $l$‎. ‎in this paper we introduce a new kind of graph energy for the binary labeled graph‎, ‎the labeled graph energy $e_{l}(g)$‎. ‎it depends on the underlying graph $g$...
