Preferential movement of solutes through soils
… model underestimates the leaching of water and solutes from the root zone. However, the computed results were substantially better than the results obtained when no preferential flow component was included in the model. The model performed best under conditions that favored preferential flow, …

Transport of solutes in complex hydrogeological media
This study presents numerical simulations of conservative solute transport in a complex heterogeneous porous media. A methodology to incorporate all the available information for describing the heterogeneity is developed. A Particle Tracking Random Walk method is used to simulate the solute …

FACTORS AFFECTING THE TRANSPORT OF SOLUTES THROUGH BRONCHIAL MUCUS
The diffusion of solutes in human bronchial mucus gel has been studied. Using the method of layer analysis and radioactive tracers the diffusion coefficients and self diffusion coefficients of several antibiotics and of glucose, sucrose, inulin and decamethonium iodide in mucus have been …

Interactions between solutes in displacement solutions and oil bearing rocks.
Studies of adsorption of several surfactants from aqueous solution onto kaolin have been made, such as might be employed in an enhanced oil recovery process. Investigations of the surfactants were carried out with regard to pH, ionic strength, temperature, the addition of short chain aliphatic …

Transport of Liquid Phase Organic Solutes in Liquid Crystalline Membranes
… PCH5 LCs (liquid crystals) and separations of solutes dissolved in aqueous phases were performed while monitoring solute concentration via UV-VIS spectrometry. The diffusing organic solutes, which consist of one aromatic ring and various functional groups, were selected to exclude molecular …

Thermochemical Study of Crystalline Solutes Dissolved in Ternary Hydrogen-Bonding Solvent Mixtures
… the thermochemical properties of nonelectrolyte solutes dissolved in ternary solvent mixtures, and to develop mathematical expressions for predicting and describing behavior in the solvent mixtures. Forty-five ternary solvent systems were studied containing an ether (Methyl tert-butyl ether, …

The Effects of Solutes, Polymers and Their Mixtures on Mold Conidia Germination
Water activity (Aw) was long held to be the primary predictor of microbial activity in food systems. Recently, it was shown that different components present in food systems also influenced microbial growth and the minimum Aw at which microbial activity occurred. Thus, water activity alone is not a …

A Theoretical and Experimental Investigation of Evaporation From Drops Containing Nonvolatile Solutes
… of evaporation from drops containing nonvolatile solutes is incomplete, preventing the establishment of viable vaporization models for such drops.

Improvements to Polyamide Reverse Osmosis Membranes for Removal of Small, Neutral, Hydrophilic Solutes
… (RO). RO uses permselective membranes to remove solutes from source water while allowing clean permeate to pass through. While RO facilities treating municipal wastewater for potable purposes are already in operation, selectivity limitations to state-of-the-art RO membranes force these facilities …

Elucidation Of Chiral Recognition Mechanisms Of Solutes By Amylose Tris[(s)-Alpha-Methylbenzylcarbamate] Sorbent
… HO (S-benzoin) for S-benzoin.Three additional solutes containing the same functional group, O=C-C-OH, as benzoin were studied: ethyl lactate (EL), methyl mandelate (MM), and pantolactone (PL). IR, DFT, and molecular simulations lead to a general hypothesis for the chiral recognition mechanism …

Sorption and Biodegradation of Organic Solutes Undergoing Transport in Laboratory-scale and Field-scale Heterogeneous Porous Media.
The first study focused on the magnitude and rate of sorption of hydrophobic organic compounds by two, well-characterized soils. The composition of organic matter had a small effect on the magnitude of the organic carbon normalized equilibrium distribution coefficients. The sorbates sorbed more …

Improving radiation resistance of solid solutions by addition of defect trapping solutes: Atomistic simulations and continuum modeling
Many radiation damage phenomena are driven by the production and fluxes of point defects, particularly in alloys. The addition of defect-trapping solute has been proposed to improve radiation damage tolerance. Selecting effective solute is complicated however, because the trapping is a complex …
