Evaluation of Transport Properties and Energy Conversion of Bacterial Cellulose Membrane Using Peusner Network Thermodynamics

Entropy, 2022
We evaluated the transport properties of a bacterial cellulose (BC) membrane for aqueous ethanol solutions. Using the Rr version of the Kedem–Katchalsky–Peusner formalism (KKP) for the concentration polarization (CP) conditions of solutions, the osmotic ...

Influence of the anion specificity on the anodic polarization of titanium [PDF]

, 2011
The anodic polarization of titanium in the presence of selected electrolytes at 0.1 mol/L concentration has been investigated. The results were interpreted according to the categorization of anions based on their cosmotrope/chaotrope character.

Inducing Deep Sweeps and Vortex Ejections on Patterned Membrane Surfaces to Mitigate Surface Fouling

Membranes
Patterned membrane surfaces offer a hydrodynamic approach to mitigating concentration polarization and subsequent surface fouling. However, when subjected to steady crossflow conditions, surface patterns promote particle accumulation in the recirculation

Carbonation of Ammonium Diuranate Filtrate to Enhance Uranium Rejection by Nanofiltration

Membranes
A commercial polymeric nanofiltration membrane (NF270, DuPont) was employed for uranium removal from ammonium diuranate filtrate (ADUF). Carbonate supplementation through ammonium carbonate addition enhanced uranium rejection via formation of uranyl ...

Single-Cell Tests to Explore the Reliability of Sofc Installations Operating Offshore

Energies, 2020
This paper studies the robustness of off-shore solid oxide fuel cell (SOFC) installations and the nature and causes of possible cell degradation in marine environments. Two important, cathode-related, impediments to ensuring SOFC reliability in off-shore

Numerical investigation of the effect of periodic turbulence promoters on the performance enhancement of nanofiltration modules. [PDF]

Journal of Hydraulic Structures
A new method for increasing the permeate flux of a nanofiltration module is presented. In a wall-patterned flat sheet membrane module, three distinct patterned walls were designed for the feed channel.

Assessment of Sieverts Law Assumptions and ‘n’ Values in Palladium Membranes: Experimental and Theoretical Analyses

Membranes, 2021
Palladium and palladium alloy membranes are superior materials for hydrogen purification, removal, or reaction processes. Sieverts’ Law suggests that the flux of hydrogen through such membranes is proportional to the difference between the feed and ...

Numerical Studies of Cell Stack for Zinc-Nickel Single Flow Battery

International Journal of Electrochemical Science, 2019
A three-dimensional stationary model is established, based on the universal conservation laws and a kinetic model for reaction involving hydroxide and zinc ions, is applied to describe a zinc-nickel single flow battery cells stack. The model is validated
