• Cr(VI) removal by iron-biochar (Fe-BC) was evaluated machine learning. Direct impact of impregnated-Fe content on limited. Indirect impacts Fe were critical due to variable Fe-BC properties. Impregnated-Fe improved SOFGs contents for removal. C−O more than C=O Data mining and knowledge discovery learning (ML) have recently come into application in environmental remediation, especially the exp...

In this study, the iron-based carbon composite (hereafter FCN-x, x = 0, 400, 500, and 600 calcination) was synthesized by a simple high-temperature pyrolysis method using iron-containing sludge coagulant generated from wastewater treatment settling ponds in chemical plants. The FCN-x used for adsorptive reduction of aqueous phase Cr(VI) effectively. characterized scanning electron microscopy (S...

• Zircaloy-2 exposed in BWR was analysed with APT before and after breakaway. Fe–Cr clusters Sn were analysed. Layers of anticorrelated layers higher concentration. The clustering similar breakaway, a small increase size. observations might be used to better understand Atom probe tomography this work study the metal close metal/oxide interface zirconium alloy three nine annual cycles operation ...

Background: The presence of heavy metals in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish. Canned fish is consumed regularly in many countries. In this study, the levels of heavy metals Cu, Ni, Fe and Cr were evaluated in commercial canned fish products that are commonly consumed in Iran. The canned fish ...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...
