background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...

The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...

An analytic model describing substitutional solid solution strengthening in body-centered cubic (BCC) complex, concentrated alloys (CCAs) based on a/2<111> screw dislocation mobility is developed and presented. At lower temperatures it assumed that dipole dragging the rate limiting mechanism, as temperature increases this changes to a jog mechanism. While both mechanisms are contained Suzuki's ...
