CytroCell@Nafion: Enhanced Proton Exchange Membranes

Global Challenges
We investigate the use of lemon CytroCell nanocellulose as a new biobased filler for Nafion‐based proton exchange membranes. Pristine and composite membranes are prepared via casting and solvent evaporation technique.

Development of Composite Membranes as Selective Adsorbent for Yttrium Ion

International Journal of Electrochemical Science, 2013
Polybenzimidazole based composite membranes (65 TSAD, 50 TSAD and 35 TSAD) were prepared by incorporating different amounts (wt %) of inorganic hetero poly acids (IHAD) into polybenzimidazole (PBI) matrix.

Lipids Composition in Plant Membranes [PDF]

Cell Biochemistry and Biophysics, 2020
AbstractThe paper focuses on the selected plant lipid issues. Classification, nomenclature, and abundance of fatty acids was discussed. Then, classification, composition, role, and organization of lipids were displayed. The involvement of lipids in xantophyll cycle and glycerolipids synthesis (as the most abundant of all lipid classes) were also ...

Water Transport in Composite Membranes Containing Silica: Temperature and Relative Humidity Effects

International Journal of Electrochemical Science, 2011
The aim of this work is to show the water flux across composite proton exchange membranes containing silica and SBA-15 fillers. The experiments were carried out using a gated cell in order to control the temperature and relative humidity (80 to 100 ºC ...

Random walk with barriers: Diffusion restricted by permeable membranes

, 2010
Restrictions to molecular motion by barriers (membranes) are ubiquitous in biological tissues, porous media and composite materials. A major challenge is to characterize the microstructure of a material or an organism nondestructively using a bulk ...

Cellulose Nanofiber-Assisted Dispersion of Halloysite Nanotubes via Silane Coupling Agent-Reinforced Starch–PVA Biodegradable Composite Membrane

Membranes, 2022
HNTs (halloysite nanotubes) are widely used in reinforcing material, often used in material reinforcement and particle loading. However, their easy agglomeration causes them to have great limitations in application.
