A novel, versatile route to phosphorus- and carbon-substituted η(5)-phosphacyclohexadienyl complexes was developed. Reaction of the anionic 2,4,6-triphenylphosphinine iron complex [K([18]crown-6)(thf)2][Cp*Fe(PC5Ph3H2)] (1) with selected main group element electrophiles afforded the new complexes [Cp*Fe(2-endo-H-PC5Ph3H2)] (endo-3), [Cp*Fe(2-exo-H-PC5Ph3H2)] (exo-3), [Cp*Fe(1-Me-PC5Ph3H2)] (4),...

Iron species can act as electron donors, acceptors or serve a sorbent to co-precipitate contaminants. These properties, along with its relatively low cost material, make iron an ideal compound for environmental applications in the removal of pollutants from water and wastewater. This study assesses use metallic reductant toxic Cr(VI) aqueous solutions, well hexavalent (ferrates) organic compoun...

Biological mechanisms of disinfection not only vary by disinfectant but also remain well understood. We investigated the physiological and transcriptomic response Escherichia coli at late stationary phase to ferrate monochloramine in amended lake water. Although treatments similarly reduced culturable cell concentrations 3-log10, 64% 11% treated cells were viable following treatment, respective...

This paper summarizes the findings of a pre-design feasibility analysis assessing the restoration of significant portions of wetlands in southeast Louisiana by providing nutrients through the introduction of treated municipal wastewater effluent. Wetlands assimilation is a process whereby properly treated and disinfected municipal wastewater treatment plant effluent is used to provide a source ...

Infection by the ciliate protozoan Ichthyophthirius multifiliis Fouquet, 1876 causes significant economic losses in freshwater aquaculture worldwide. Following the ban on the use of malachite green for treating food fish, there has been extensive research aimed at identifying suitable replacements. In this paper we critically assess drug and non-drug interventions, which have been tested for us...
