Carboxylated Graphene Oxide (c-GO) Embedded ThermoPlastic Polyurethane (TPU) Mixed Matrix Membrane with Improved Physicochemical Characteristics

Membranes, 2023
Water is an important component of our life. However, the unavailability of fresh water and its contamination are emerging problems. The textile industries are the major suppliers of contamination of water, producing high concentrations of heavy metals ...

Beneath the Bark: Assessing Woody Stem Water and Carbon Fluxes and Its Prevalence Across Climates and the Woody Plant Phylogeny

Frontiers in Forests and Global Change, 2021
While woody stems are known to influence carbon and water dynamics, direct exchange with the atmosphere is seldom quantified, limiting our understanding of how these processes influence the exchange of mass and energy.

Flux Increase Occurring When an Ultrafiltration Membrane Is Flipped from a Normal to an Inverted Position—Experiments and Theory

Membranes, 2022
The effects of flipping membranes with hydrophilic/hydrophobic asymmetry are well documented in the literature, but not much is known on the impact of flipping a membrane with dense/porous layer asymmetry.

Preparation and Characterization of the Forward Osmosis Membrane Modified by MXene Nano-Sheets

Membranes, 2022
The Forward Osmosis (FO) membrane was the core of FO technology. Obtaining a high water flux while maintaining a low reverse solute flux has historically been considered the gold standard for a perfect FO membrane.

Soil hydrology and soil properties on a partially reforested hillside in the Central Alps

Journal of Forest Science, 2012
The landscape on southern exposed hillsides in the inneralpine Vinschgau Valley (Northern Italy) is shaped by many thousand years of cultivation. Phases of intensive land use and deforestation were followed by phases of natural regeneration and later by ...
