The amendment of the subsurface with nanoscale metallic iron particles (nano-Fe(0)) has been discussed in literature as an efficient situ technology for groundwater remediation. However, introduction this was controversial and its efficiency never univocally established. This unsatisfying situation motivated communication whose objective a comprehensive discussion intrinsic reactivity nano-Fe(0) based on contemporary knowledge mechanism contaminant removal by Fe(0) mathematical model. It is...
Abstract Over the past 30 years literature has burgeoned with in situ approaches for groundwater remediation. Of methods currently available, use of metallic iron (Fe 0 ) permeable reactive barrier (PRB) systems is one most commonly applied. Despite such interest, an increasing amount experimental and field observations have reported inconsistent Fe operation compared to contemporary theory. In current work, a critical review physical chemistry aqueous corrosion porous media presented....
Water extraction from plants by evaporation is ubiquitous in nature, and essential for most uses of wood-based products, yet little known about the internal drying mechanisms. The authors use NMR x-ray computed tomography to observed effects at different length scales. In typical porous media due mainly capillary effects, but wood structure's bound water controls free liquid pores, throughout process. Transfers between seem play a major role interaction plantlike systems with water, this...
Vascular plants, a vast group including conifers, flowering etc., are made of cellular hygroscopic structure containing water in the form either free (i.e., standard liquid state) or bound absorbed cell walls) water. From nuclear magnetic resonance techniques, we distinguish dynamics and typical material (softwood) with such structure, under convective drying. We show that extraction relies on two mechanisms diffusion contiguous regions sample, which respectively still contains only However,...
Abstract Earlywood (EW) and latewood (LW) have different hygromechanical behaviors, if subjected to relative humidity (RH) variations. To understand this effect better, the adsorption mechanisms of EW LW Douglas fir were studied by 2D 1 H NMR relaxometry under conditions equilibrium moisture content (EMC) at 20°C. Two bound water components detected with relaxation times T 2 indicating that they are located in distinct environments but these similar LW. Sorption isotherms calculated analyzed...
The wetting properties of a liquid along cell-walls plant-like systems or in porous hydrogels change from poor to good when the walls are saturated with bound water, which then allows displacement. As consequence, dynamics capillary imbibition free water hygroscopic may be strongly damped (by several orders magnitude) although can freely climb over significant heights. This process might contribute regulation absorption unsaturated wood and could explored design materials tunable adsorption.
