Assessing the aggregation behaviour of iron oxide nanoparticles under relevant environmental conditions using a multi-method approach [PDF]

, 2013
Iron nanoparticles are becoming increasingly popular for the treatment of contaminated soil and groundwater; however, their mobility and reactivity in subsurface environments are significantly affected by their tendency to aggregate.

Nanoscale Zero‐Valent Iron for Sulfide Removal from Digested Piggery Wastewater [PDF]

Journal of Nanomaterials, 2014
The removal of dissolved sulfides in water and wastewater by nanoscale zero‐valent iron (nZVI) was examined in the study. Both laboratory batch studies and a pilot test in a 50,000‐pig farm were conducted. Laboratory studies indicated that the sulfide removal with nZVI was a function of pH where an increase in pH decreased removal rates.

Enhanced Biogas Production from Nanoscale Zero Valent Iron-Amended Anaerobic Bioreactors [PDF]

Environmental Engineering Science, 2015
Addition of nanoscale zero valent iron (NZVI) to anaerobic batch reactors to enhance methanogenic activity is described. Two NZVI systems were tested: a commercially available NZVI (cNZVI) slurry and a freshly synthesized NZVI (sNZVI) suspension that was prepared immediately before addition to the reactors.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
