Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Nano zero-valent iron (nZVI) has attracted much more attention for its potential applications
in the fields of environmental contaminant remediation and detoxification. Generally, nZVI …

This review examines characterization challenges inherently associated with understanding
nanomaterials and the roles surface and interface characterization methods can play in …

Mass transfer and oxidant utilization are perhaps two of the most critical issues in sulfate
radical (SO 4•−) based advanced oxidation technologies (AOTs) and their scaled-up …

The important role that surface chemical analysis methods can and should play in the
characterization of nanoparticles is described. The types of information that can be obtained …

Under anoxic conditions, soluble pertechnetate (99TcO4–) can be reduced to less soluble
TcO2· n H2O, but the oxide is highly susceptible to reoxidation. Here we investigate an …

This guide briefly summarizes issues and considerations important for the use of x-ray
photoelectron spectroscopy (XPS) for characterizing nanoparticles, which are important in …

Water decontamination became a priority-based focused area for environmental scientists
and researchers these days. Several contaminants like pesticides (chlorpyrifos, endosulfan …

Oxidation− reduction potential (ORP) measurements have been widely used to assess the
results of injection of nano zerovalent iron (nZVI) for groundwater remediation, but the …

Surface chemistry is an important factor for quality control during production of
nanomaterials and for controlling their behavior in applications and when released into the …
