Two cadmium(ii) coordination polymers (CPs) of compositions {[Cd(HO)(4-BPDB)][BPDC]} (CP1) and {[Cd(HO)(BrIP)(BTTMB)]·4MeOH} (CP2) have been synthesized by solvothermal methods and characterized by several analytical methods including SXRD (Single Crystal X-ray Diffraction). The structure of CP1 can be described as a 1D cationic chain, {[Cd(HO)(4-BPDB)]} and discrete BPDC counter anions. The structure of CP2 revealed an undulated 2D sql net comprising Cd nodes bridged by the ditopic N-donor, BTTMB and dicarboxylate BrIP involved in μ-ηηηη coordination. Supramolecular interactions in both CPs generate 3D hydrogen bonded architectures. The solid state fluorescence properties of these d metal ion containing CPs have been investigated. Fluorescence emission of CP1 suspended in acetonitrile is observed to be selectively quenched by acetone (LOD = 0.15 mM) over other common laboratory solvents.

Achieving high battery performance from low-cost, easily synthesisable electrode materials is crucial for advancing energy storage technologies. Metal organic frameworks (MOFs) combining inexpensive transition metals and organic ligands are promising candidates for high-capacity cathodes. Iron-chloranilate-water frameworks are herein reported to be produced in aqueous media under mild conditions.

In this work, we investigate the development of polymer electrolytes for sodium batteries based on sulfonamide functional polymer nanoparticles (NaNPs). The synthesis of the polymer NaNPs is carried out by emulsion copolymerization of methyl methacrylate and sodium sulfonamide methacrylate in the presence of a crosslinker, resulting in particle sizes of 50 nm, as shown by electron microscopy. Then, gel polymer electrolytes are prepared by mixing polymer NPs and different organic plasticizers including carbonates, glymes, sulfolanes and ionic liquids.

Pt-based intermetallic alloy particles with a Pt skin layer have higher catalytic activity than solid-solution alloy particles and have attracted considerable attention for practical applications in polymer electrolyte fuel cells. However, the reason for the superior performance of intermetallic alloys is not yet fully understood. Because the catalytic reaction proceeds on the topmost surface of the particle, it is necessary to clarify the relationship between the periodic structure of the intermetallic alloy and the Pt atomic coordination on the surface.

For Zn metal batteries, the Zn anode faces several challenges, including Zn dendrites, hydrogen evolution, and corrosion. These issues are closely related to the Zn deposition process at the electrode/electrolyte interface. Herein, we propose interfacial engineering to protect the Zn anode and induce homogeneous deposition using conjugated cyclized polyacrylonitrile (cPAN) polymer nanofibers.
