The objective of this investigation is to synthesize and investigate zero-valent iron (ZVI) nanoparticles (NPs) for bioremediation applications. ZVI-NPs were fabricated by chemical reduction using a ferrous salt solution with poly(N-vinylpyrrolidone) (PVP), used as stabilizer. synthesis was conducted without ultrasonic treatment. ZVI NPs characterized scanning electron microscopy (SEM), transmi...

iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...

Dechlorination reactions at sp(2) C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

We construct a mirabolic analogue of the geometric Satake equivalence. also prove an equivalence that relates representations supergroup with category $GL(N-1,{\mathbb C}[\![t]\!])$-equivariant perverse sheaves on affine Grassmannian $GL_N$. explain how our equivalences fit into more general framework conjectures due to Gaiotto and Ben-Zvi, Sakellaridis Venkatesh.

This is a companion paper of arXiv:1909.11492. We prove an equivalence relating representations degenerate orthosymplectic supergroup with the category $SO(N-1,{\mathbb C}[\![t]\!])$-equivariant perverse sheaves on affine Grassmannian $SO_N$. explain how this fits into more general framework conjectures due to Gaiotto and Ben-Zvi, Sakellaridis Venkatesh.

Granular zero-valent iron (ZVI) has been widely used to construct permeable reactive barriers (PRB) for the in situ remediation of groundwater contaminated with halogenated hydrocarbons. In the anaerobic condition of most groundwater flow systems, iron undergoes corrosion by water and results in hydrogen gas generation. Several studies have shown that some of the hydrogen gas generated at the i...
