Asymmetric bipolar membrane: A tool to improve product purity [PDF]

open access: yesJournal of Membrane Science, 2007
Bipolar membranes (BPMs) are catalytic membranes for electro-membrane processes splitting water into protons and hydroxyl ions. To improve selectivity and current efficiency of BPMs, we prepare new asymmetric BPMs with reduced salt leakages. The flux of salt ions across a BPM is determined by the co-ion transport across the respective layer of the ...

Risk taking behaviour in bipolar affective disorder [PDF]

open access: yes, 2010
This piece of research was designed to explore the nature of risk taking behaviour and impulsivity in bipolar affective disorder. Involvement in pleasurable activities that have a high potential, or risk, for unwanted consequences forms one of the DSM IV

Two Functional Classes of Rod Bipolar Cells in the Healthy and Degenerated Optogenetically Treated Murine Retina

open access: yesFrontiers in Cellular Neuroscience, 2022
Bipolar cells have become successful targets for optogenetic gene therapies that restore vision after photoreceptor degeneration. However, degeneration was shown to cause changes in neuronal connectivity and protein expression, which may impact the ...

The influence of acid activation of bentonite in the composition of a bipolar membrane on the characteristics of the electrodialysis conversion of sodium sulphate

open access: yesКонденсированные среды и межфазные границы, 2022
The effect on the characteristics of the electrodialysis process of the acid activation of bentonite included in the cationexchange layer of an experimental bipolar membrane obtained by applying a liquid LF-4SK cation-exchange layer containing ...

Electrodialysis Desalination with Simultaneous pH Adjustment Using Bilayer and Bipolar Membranes, Modeling and Experiment

open access: yesMembranes, 2022
A kinetic model of the bipolar electrodialysis process with a two-chamber unit cell formed by a bilayer (bipolar or asymmetric bipolar) and cation-exchange membrane is proposed.

Radiation-Induced Asymmetric Grafting of Different Monomers into Base Films to Prepare Novel Bipolar Membranes

open access: yesMolecules, 2021
We prepared novel bipolar membranes (BPMs) consisting of cation and anion exchange layers (CEL and AEL) using radiation-induced asymmetric graft polymerization (RIAGP).

Current–Voltage Characteristics and Solvent Dissociation of Bipolar Membranes in Organic Solvents

open access: yesMembranes, 2022
In this work, the chronopotentiometric responses, pH changes, and current–voltage (I–V) characteristics of bipolar membrane (BPM)/LiCl–organic solvent systems were measured and compared with those of the BPM/LiCl–water system.

Improving the Stability, Selectivity, and Cell Voltage of a Bipolar Membrane Zero‐Gap Electrolyzer for Low‐Loss CO2 Reduction

open access: yesAdvanced Materials Interfaces, 2023
Electrolyzers for CO2 reduction containing bipolar membranes (BPM) are promising due to low loss of CO2 as carbonates and low product crossover, but improvements in product selectivity, stability, and cell voltage are required.

Asymmetric acidic/alkaline N2 electrofixation accelerated by high‐entropy metal–organic framework derivatives

open access: yesCarbon Energy, 2023
High‐entropy materials are composed of five or more metal elements with equimolar or near‐equimolar concentrations within one crystal structure, which offer remarkable structural properties for many applications.
