Improved Hydrolytic and Mechanical Stability of Sulfonated Aromatic Proton Exchange Membranes Reinforced by Electrospun PPSU Fibers

Membranes, 2022
The hydrolytic stability of ionomer membranes is a matter of concern for the long-term durability of energy storage and conversion devices. Various reinforcement strategies exist for the improvement of the performances of the overall membrane. We propose

Viscosity, Degree of Polymerization, Water Uptake, and Water Solubility Studies on Experimental Dichloro-BisGMA-Based Dental Composites

Applied Sciences, 2021
The objective of this work was to investigate the advantages of using dichloro bisphenol A-glycidyl methacrylate (dCl-BisGMA) as a potential matrix for dental resin composites. A series of model composites containing 65 wt% resin (urethane dimethacrylate/

Global Heat Uptake by Inland Waters [PDF]

Geophysical Research Letters, 2020
AbstractHeat uptake is a key variable for understanding the Earth system response to greenhouse gas forcing. Despite the importance of this heat budget, heat uptake by inland waters has so far not been quantified. Here we use a unique combination of global‐scale lake models, global hydrological models and Earth system models to quantify global heat ...

Water use strategies of Ferula bungeana on mega-dunes in the Badain Jaran Desert

Frontiers in Plant Science, 2022
In desert ecosystems, ephemeral plants have developed specialized water use strategies in response to long-term natural water stress. To examine the water use strategies of desert ephemeral plants under natural extreme drought conditions, we investigated

Passive water control at the surface of a superhydrophobic lichen [PDF]

, 2011
Some lichens have a super-hydrophobic upper surface, which repels water drops, keeping the surface dry but probably preventing water uptake. Spore ejection requires water and is most efficient just after rainfall.

Water uptake in parallel fractures [PDF]

Capillarity, 2021
Water uptake in rock fractures caused by rainfall plays a significant role in slope stability analysis. Since the fracture network system has complicated structures and multiple scales, the models based on the averaged system cannot account for these properties.

Dielectric properties of epoxy silica and boron nitride nanocomposites and moisture/temperature influences

IET Nanodielectrics, 2018
The epoxy resin was filled with nano-BN, surface treated, and untreated nano-SiO(2). Measurements of dielectric spectroscopy cover the range of frequency from 10^−2 to 10^5 Hz and will relate to the hydration of samples.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]

, 2009
In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...

Nitrogen forms affect root structure and water uptake in the hybrid poplar [PDF]

, 2011
The study analyses the effects of two different forms of nitrogen fertilisation (nitrate and ammonium) on root structure and water uptake of two hybrid poplar (Populus maximowiczii x P. balsamifera) clones in a field experiment.
