Synergistic Effect of Functionalized Nanokaolin Decorated MWCNTs on the Performance of Cellulose Acetate (CA) Membranes Spectacular

open access: yesNanomaterials, 2016
In order to enhance salt rejection level and high pressure mechanical integrity, functionalized nanokaolin decorated multiwall carbon nanotubes (FNKM, 0–5 wt % loading) were incorporated into a cellulose acetate (CA) matrix using high temperature ...

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

open access: yesMembranes, 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.

Comparison among monitoring strategies to assess water flow dynamic and soil hydraulic properties in agricultural soils

open access: yesSpanish Journal of Agricultural Research, 2015
Irrigated agriculture is usually performed in semi-arid regions despite scarcity of water resources. Therefore, optimal irrigation management by monitoring the soil is essential, and assessing soil hydraulic properties and water flow dynamics is ...

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

open access: yesMembranes, 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.

Mixed Nanosheet Membranes Assembled from Chemically Grafted Graphene Oxide and Covalent Organic Frameworks for Ultra-High Water Flux.

open access: yesACS Applied Materials and Interfaces, 2019
2D Graphene oxide (GO) membranes attract great attention due to ultrathin thickness and superior molecular sieving ability, but the low flux and instability in aqueous environments remain the major challenges for practical applications. In this study, we

Latent Heat Flux Profiles from Collocated Airborne Water Vapor and Wind Lidars during IHOP_2002

open access: yes, 2007
Latent heat flux profiles in the convective boundary layer (CBL) are obtained for the first time with the combination of the DLR water vapor differential absorption lidar (DIAL) and the NOAA high resolution Doppler wind lidar (HRDL).

Distributions of critical flux: modelling, experimental analysis and consequences for cross-flow membrane filtration [PDF]

open access: yes, 2005
This paper discusses the distribution of critical flux (DCF) in cross flow filtration. These distributions are described here by a normal function with a mean critical flux and its standard deviation.
