...Abstract This paper focuses on a preliminary study of the use of halophytes to manage the characteristics of soil. Halophytes, such as switchgrass and salt bush, are capable of altering the characteristics of the soil over time, possibly reducing conductivity and corrosivity. These types of plants...

... in an electrochemically active state. These grouts typically contain salts or humectants comprised of high pH media. Research has shown these grout additives to be capable of activating the zinc anode only on a limited, short-term basis. This paper discusses laboratory testing of a highly conductive proprietary grout...

...The mechanism by which a nominally non-corrosive, poorly conducting hydrocarbon stream becomes corrosive needs to be understood. Two possible routes for the generation of corrosive environments that are being considered are: Reaction between the trace levels of water and hydrocarbons to produce...

... of the mean electrolyte-resistance values has shown an excellent agreement with the theoretical predictions of Maxwell's model of the electrical conductivity in two-phase media over the whole VOC range investigated, provided that hydrodynamic conditions ensure the homogeneity of the mixture.

In this work, conducting atomic force microscopy (C-AFM) is demonstrated as a technique for qualitative analysis of electrical conductivity at localized sites on surfaces. Electrical conductivity may arise...

The concentrations of treatment were approximately those which would obtain for current commercial...

... recommendations for changes in basin operations to permit extended longer term interim storage. The changes were implemented during 1994-1996 and have resulted in significantly improved basin water quality with conductivity in the 1-3 μS/cm range. Under these improved conditions, no new pitting has been observed...
