“…However, on the basis of the N 1s spectrum, the ratio of the peak area between pyridine N and pyrrole N ( R s ) was calculated to confirm this hypothesis (Figure c). Referring to XPS data, pyridine N was considered to be more involved in coordination than pyrrole N . Thus, we assumed that the binding sites are mostly pyridine N. Compared to that of Dense-PBI, pyridine N in Turing-PBI takes part in the coordination; therefore, R s is reduced from 0.53 to 0.24.…”

Zinc-based batteries are promising for use as energy storage devices owing to their low cost and high energy density. However, zinc chemistry commonly encounters serious dendrite issues, especially at high areal capacities and current densities, limiting their application. Herein, we propose a novel membrane featuring ordered undulating stripes called “Turing patterns”, which can effectively suppress zinc dendrites and improve ion conductivity. The crests and troughs in the Turing membrane can effectively adjust the Zn(OH)4 2– distribution and provide more zinc deposition space. The coordinated Cu ions during membrane formation can interact with Zn(OH)4 2–, further smoothing zinc deposition. Even at a high current density of 80 mA·cm–2, the Turing membrane enables an alkaline zinc–iron flow battery (AZIFB) to work stably with an ultrahigh areal capacity of 160 mA·h·cm–2 for approximately 110 cycles, showing an energy efficiency of 90.10%, which is by far the highest value ever reported among zinc-based batteries with such a high current density. This paper provides valid access to zinc-based batteries with high areal capacities based on membrane design and promotes their advancement.

“…In a study, a new technique has been developed for the fabrication of solvent-resistant NF membranes based on metal-polymer coordination (MPC) through a facile synthesis method. The monitored deposition of copper(I) iodide supported the refinement of the molecular sieving performance of MPC membranes by varying both their chemical interaction and morphology (Hardian et al 2021).…”

Water scarcity is not a novel issue. It has already affected almost every continent in this blue planet. It is driven by two primary sources: increasing demand for fresh water due to the increase in population and overexhaustion of the available freshwater resources. During the past decade, stress has been given to extract fresh, clean and safe potable elixir of life from the bountiful stores of sea water by exploiting various technologies. As nanomaterials are providing promising solutions to almost all our problems, they are again being accessed in order to combat the problem of global freshwater scarcity. Desalination methods have marvellously improved under the impact of nanomaterials. Different metallic nanomaterials are being used to serve this purpose; for example, silver, iron, zinc, titanium dioxide in addition to natural and synthetically derived polymeric bionanomaterials. In the present paper, a brief account of all the metallic nanomaterials which are being used for treatment of water has been provided by thorough investigation on the research done till now. It strives to throw light on various materials and methods which are based on the exploitation of nanotechnology for the treatment of water.

“…Hardian et al developed metal–polymer coordination (MPC) solvent-resistant NF membranes owing to the superior thermal and complexation ability of benzimidazole moieties. 47 The formation of coordination bonds between the metal (copper( i ) iodide, CuI) and PBI chains protected the membranes from dissolving in harsh organic solvents and improved the mechanical properties. The novel method to prepare MPC membranes provides a new route besides covalent cross-linking for the preparation of OSN membranes with tailored molecular sieving performance.…”
