Proton Conductivity of Nafion/Ex-Situ Sulfonic Acid-Modified Stöber Silica Nanocomposite Membranes As a Function of Temperature, Silica Particles Size and Surface Modification

open access: yesMembranes, 2016
The introduction of sulfonic acid modified silica in Nafion nanocomposite membranes is a good method of improving the Nafion performance at high temperature and low relative humidity.

Modelling the Effect of Salt and PEG on Water Uptake in Wheat Seeds

open access: yesAgronomy, 2021
Water uptake is a seminal process in seed germination. Salt and polyethylene glycol (PEG) are known to retard seed germination rates and percentages, which is often attributed to osmotic effects.

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

The impact of vegetation on fractionation of rare earth elements(REE) during water–rock interaction [PDF]

open access: yes, 2006
Previous studies on waters of a streamlet in the Vosges mountains (eastern France) have shown that Sr and rare earth elements (REE) principally originate from apatite dissolution during weathering. However, stream water REE patterns normalized to apatite

Foliar water uptake changes the world of tree hydraulics

open access: yesnpj Climate and Atmospheric Science, 2019
Climate change-induced drought events have become more prevalent during recent years, resulting in an increasing number of high-impact studies focussing on this important topic. In their recent review, Choat et al.

Ecosystem warming increases sap flow rates of northern red oak trees

open access: yesEcosphere, 2016
Over the next century, air temperature increases up to 5°C are projected for the northeastern United States. As evapotranspiration strongly influences water loss from terrestrial ecosystems, the ecophysiological response of trees to warming will have ...

Online Pre-Treatment of Thermomechanical Pulp with Emulsified Maleated Polypropylene for Processing of Extruded Thermoplastic Composites

open access: yesFibers, 2021
The effectiveness of maleated polypropylene (MAPP) in emulsified form for the pre-treatment of thermo-mechanical pulp (TMP) before extrusion with polypropylene fibres was evaluated.
