TL;DR: The surface elemental distribution maps of the nZVI@HCl-BC after reaction with Cr(VI) showed that Fe, Cr and O elements were deposited on the surface of Hcl-BC evenly, indicating that the formed Cr(III)/Fe(III) could settle on thesurface of HCl- BC uniformly rather than coated only on the n ZVI surface.

TL;DR: Spectroscopic analyses demonstrate that the enhanced TCE dechlorination was associated with the presence of FeS on the surface of S/NZVI, revealing that the FeS layer could be able to alleviate the surface passivation of NZVI caused by oxidation.

TL;DR: In this article, biochar-supported nanoscale zero-valent iron (nZVI/BC) was synthesized and used as an activator for Fenton-like removal of sulfamethazine (SMT).

TL;DR: The technology of integrating nanoscale zero-valent iron (nZVI) and functional anaerobic bacteria has broad prospects for groundwater remediation and the main factors influencing the removal efficiency of contaminants in the integrated treatment system include nZVI species and dosage, inorganic ions, organic matters, pH, type of pollutants, temperature, and carbon/energy sources.

TL;DR: This study evaluated the contributions of environmental variables to the variations in bacterial 16S rDNA, nitrifying and denitrifying genes abundances during composting in the presence of polyvinylpyrrolidone coated silver nanoparticles to find that different genes shared different relationships with environmental parameters.
