Magnetic sulfide-modified nanoscale zerovalent iron (S-nZVI) is of great technical and scientific interest because of its promising application in groundwater remediation, although its synthesis is still a challenge. We develop a new nanoparticle seeding method to obtain a novel and reactive nanohybrid, which contains an Fe(0) core covered by a highly sulfidized layer under high extent of sulfi...

Nanoscale iron particles decorated graphene sheets synthesized via sodium borohydride reduction of graphene oxide, showed enhanced magnetic property, surface area and Cr(vi) adsorption capacity compared to bare iron nanoparticles.

For the very few people who may not have an understanding of nanotechnology, here is a quick overview. Nanotechnology is an emerging multidisciplinary technology that involves the synthesis of molecules in the nanoscale (i.e., 10 9 m) size range. The origin of the term ‘‘nanotechnology’’ is derived from the Greek word ‘‘nano,’’ meaning ’’dwarf.’’ From a chemistry and material science perspectiv...

An innovative nanoscale ZnO/polybutadiene rubber composite (ZBRC) was developed as a valid alternative to TiO2 particles or immobilized TiO2 for the mineralization of chlorinated hydrocarbons without difficulties in the recovery of nanoscale photocatalyst particles. A synergistic increase in the removal of 1,1,2-trichloroethylene (TCE) through the coupled reaction processes (i.e., sorption, pho...

Abstract The purpose of the study was to evaluate possibility removing heavy metal cations from single-metal spiked soil samples, which were pretreated with nanoscale zero-valent iron (nZVI) particles. Sandy artificially contaminated copper (Cu), cadmium (Cd), nickel (Ni), and lead (Pb). Contaminated samples amended different doses nZVI (0.35, 0.70 1.05 %). A sequential extraction method used d...

Nanoscale titania particles were synthesized inside the porous coordination polymer [Zn(4)O(bdc)(3)] (bdc = 1,4-benzene-dicarboxylate, MOF-5) by adsorption of titanium isopropoxide from the gas-phase and subsequent dry oxidation and annealing.

introduction iron (fe) has a crucial biological role in human and plant growth. this micronutrient is a major player in chloroplast photosynthesis and enzymes. although some enzymes, such as fe-dependent superoxide dismutase, use molecular fe as a cofactor directly, most proteins use fe-containing factors. various studies were carried out to understand the effect of nanoparticles on the growth ...
