Modelling Water and Nutrient Uptake

open access: yes, 2000
Supplying plants with inorganic nutrients and water is a major function of roots (Nye and Tinker 1977; Nielsen 1983; Barber 1984; Jungk and Claassen 1989; Gahoonia and Nielsen 1991, 1992a,b). It is still a major challenge to agricultural research to quantitatively predict production of a crop as influenced by uptake of nutrients and water.

Species-specific differences in water uptake depth of mature temperate trees vary with water availability in the soil.

open access: yesPlant biology, 2018
Temperate tree species differ in their physiological sensitivity to declining soil moisture and drought. Although species-specific responses to drought have often been suggested to be the result of different water uptake depths, empirical evidence for ...

Recycling of Wood–Plastic Composites—A Reprocessing Study

open access: yesMacromol, 2023
Wood–plastic composites, consisting of wood particles and a thermoplastic matrix, are common composites often used in buildings as decking boards or for similar non-load-carrying applications. As these are usually semi-finished products, a certain amount

Record-Setting Sorbents for Reversible Water Uptake by Systematic Anion Exchanges in Metal–Organic Frameworks

open access: yesJournal of the American Chemical Society, 2019
The reversible capture of water vapor at low humidity can enable transformative applications such as atmospheric water harvesting and heat transfer that uses water as a refrigerant, replacing environmentally detrimental hydro- and chloro-fluorocarbons ...

The effect of water absorption on the dielectric properties of epoxy nanocomposites [PDF]

open access: yes, 2008
In this research, the influence of water absorption on the dielectric properties of epoxy resin and epoxy micro-composites and nano-composites filled with silica has been studied. Nanocomposites were found to absorb significantly more water than unfilled
