Water retention characteristics of grapheme-modified GMZ bentonite subjected to preliminary chemical cycles

Yantu gongcheng xuebao, 2023
In the deep geological repository for high-level radioactive waste, affected by the coupling of saline groundwater infiltration and nuclear decay heat, the buffer/backfill materials may undergo the chemical cycles of salinization and desalination process,

The behavior of water retention values and sheet strengths of TMP modified by carboxymethylation and methylation.

JAPAN TAPPI JOURNAL, 1990
The object of this paper is to examine the influence of the changes in water retention value (WRV) of Douglas fir TMP by post-chemical substitution on the sheet density and the sheet strength.TMP classified 42 wire mesh was modified by carboxyme-thylation and methylation to the various degree of substitution. Then, yeild, degree of substitution (DS) of

Deposition and transport of functionalized carbon nanotubes in water-saturated sand columns [PDF]

, 2012
Knowledge of the fate and transport of functionalized carbon nanotubes (CNTs) in porous media is crucial to understand their environmental impacts. In this study, laboratory column and modeling experiments were conducted to mechanistically compare the ...

The Effect of Air Entry Values on Hysteresis of Water Retention Curve in Saline Soil

American Journal of Environmental Sciences, 2009
Problem statement: The saline soil in Northeast Thailand is caused by saline groundwater rise in unsaturated zone to accumulate as salt at soil surface. Approach: This problem had been exacerbated in the last few decades by human activities e.g., deforestation and salt mining.

Saturation-Dependence of Dispersion in Porous Media [PDF]

, 2012
In this study, we develop a saturation-dependent treatment of dispersion in porous media using concepts from critical path analysis, cluster statistics of percolation, and fractal scaling of percolation clusters. We calculate spatial solute distributions

Subsurface Water Retention a Technology for Increasing the Field Use Efficiency and Water Saving Values of Cucumber Plant

Journal of Engineering, 2019
The technology of subsurface soil water retention (SWRT) uses a polyethylene ‎trough that is fixed under the root zone of the plant. It is a modern technology to increase the values of water ‎use efficiency, plant productivity and saving irrigation water by applying as little irrigation water ‎as possible.

Prediction of water retention of soils from the humid tropics by the nonparametric k-nearest neighbor approach [PDF]

, 2013
Nonparametric approaches such as the k-nearest neighbor (k-NN) approach are considered attractive for pedotransfer modeling in hydrology; however, they have not been applied to predict water retention of highly weathered soils in the humid tropics ...

Redispersibility of Paper Under Low Agitation and How It Deteriorates over Time

Recycling
In many paper applications the paper is supposed to disintegrate into its constituating fibers after disposal. This happens in water with only very little input of mechanical energy.
