Research on Alkaline Anion Exchange Membrane Fuel Cells

, 2011
In this work, we report on the preparation of a novel type of PTFE based composite anion exchange membrane for alkaline fuel cells. The membranes were synthesized by in-situ polymerization of N-vinylformamide monomer in the PTFE matrix followed by ...

Preparation of a monovalent selective anion exchange membrane through constructing a covalently crosslinked interface by electro-deposition of polyethyleneimine

, 2017
Surface modification by generating a dense anionic layer on the surface of a substrate membrane is the main method for preparing monovalent selective anion exchange membranes.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Recovery of gold from thiosulfate solutions and pulps with anion-exchange resins [PDF]

, 2002
With growing environmental and occupational safety concerns over the use of cyanide in gold processing, more acceptable alternatives are receiving increased interest. The most promising of the possible alternatives is thiosulfate.

Performances of Anion-Exchange Blend Membranes on Vanadium Redox Flow Batteries

Membranes, 2019
Anion exchange blend membranes (AEBMs) were prepared for use in Vanadium Redox Flow Batteries (VRFBs). These AEBMs consisted of 3 polymer components. Firstly, PBI-OO (nonfluorinated PBI) or F6-PBI (partially fluorinated PBI) were used as a matrix polymer.

Boron removal by electrodialysis with anion-exchange membranes

Desalination, 2006
Abstract The removal of boron from an aqueous solution was studied in a two-chamber cell separated with a commercial anion- exchange membrane as a function of current density, pH, type of the membrane, concentration and different type of salt solutions.

Stimuli‐Responsive Hierarchical Structuring Controls Survival and Programs Hydrogelation of Supramolecular Metallofibers

Advanced Materials, EarlyView.
Aqueous Zn(II) Salphen metallofibers decorated with PNIPAM undergo reversible, multi‐stimuli‐responsive hierarchical bundling. This higher‐order structuring kinetically stabilizes the otherwise fragile assemblies against dilution, acidic hydrolysis, and transmetallation, enables selective sorting of responsive fibers, and programs hydrogelation at ...
