Abstract Secondary aluminum production is required for the conservation of environment. It can significantly reduce greenhouse gas emissions and energy consumption alumina, a source primary aluminum. requires sorting processes metal scrap before starting refining process. Salt slags generated from both secondary need to be recycled/treated as they are considered hazardous byproducts. This revie...

Secondary metabolites with low molecular weight and high economic, pharmaceutical and industrial values play an important role in protecting plants against biotic and abiotic stresses. Astragalus is a medicinal herb, rich in secondary metabolites. Selenium (Se) is an essential element for humans, animals, many bacteria, and a beneficial element for plants. The plants response to selenium is dep...

Secondary zinc and lead production is addressed as one of the potential sources of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dioxin-like PCBs) due to the impurity of the raw material. However, the release inventory of PCDD/Fs and dioxin-like PCBs is very scarce for these secondary nonferrous metallurgies. This study selected typical...

Secondary reactions induced by relativistic beams in inverse kinematics in a thick target are relevant in several fields of experimental physics and technology, like secondary radioactive beams, production of exotic nuclei close to the proton drip line, and cross-section measurements for applications of spallation reactions for energy production and incineration of nuclear wastes. A general mat...

Salicylic acid (SA) is an elicitor to induce the biosynthesis of secondary metabolites in plant cells. Hydrogen peroxide (H2O2) plays an important role as a key signaling molecule in response to various stimuli and is involved in the accumulation of secondary metabolites. However, the relationship between them is unclear and their synergetic functions on accumulation of secondary metabolites ar...
