Summary: A new non-planar push-pull chromophore has been found to be an efficient system for detecting F- ion in water, with the sensing mechanism governed by H-bonding and deprotonation. However, replacing the phenyl group with DMA led to the failure of colorimetric and fluorometric detections due to masking and quenching effects. Excellent sensitivity and specificity towards F- was demonstrated in a successful tissue paper-based visual strip detection method.

Summary: In this study, anion-modulation in CoMoO4 nanoplates was used to couple the hydrogen evolution reaction (HER) and urea oxidation reaction (UOR) in a convenient and efficient urea-assisted hydrogen-production system. Nitrogen doping and phosphorus doping showed excellent activity towards alkaline HER and UOR, respectively. The N-CoMoO4 and P-CoMoO4 electrode achieved low potentials for HER and UOR, and the full urea electrolysis was stable for 24 hours at a low potential.

Summary: The study utilized a clamshell-shaped ionophore (ClS) composed of two preorganized cyanostar (CNstar) macrocycles for anion complexation via CH-hydrogen bonding. The optimized electrode displayed an anti-Hofmeister selectivity pattern towards iodide with a nanomolar detection limit. This selectivity could be altered by using an ionophore where the two CNstar macrocycles are linked together with a flexible 12-carbon chain to control the molecularity of the binding event.

Summary: In this study, a membrane material with an organically bridged polysilsesquioxane structure was successfully synthesized through copolymerization. The results showed that the introduction of hydroxyethylurea groups significantly improved the water permeability of the membrane material while maintaining a high NaCl rejection rate. The enhancement in water permeability is likely attributed to the aggregation of hydroxyethylurea groups in the membrane material, forming a hydrophilic water channel.

Summary: Synthetic receptors that modulate and fine-tune the strength of weak interactions to bind anions were studied. The receptors were designed with a urea and tetrazine motif. The impact of H-bond strength and linker length on chloride complexation was investigated, and the binding properties of chloride anions in both ground and excited states were examined using various analytical methods. A ranking of the receptors based on their complexation strength provided insights into the structure-properties relationship.

Summary: Constructing multiple heterogeneous structures improves the electrocatalytic activity of NiO, but the poor conductivity of NiO hinders charge transfer. A new organic-inorganic hybrid method is used to fabricate F-doped NiO/Ni@C catalyst which exhibits superior hydrogen evolution and urea oxidation activity. The F-doping allows electron delocalization and facilitates electron transfer from Ni to NiO, resulting in optimized H* adsorption Gibbs free energy and reduced energy barrier. The F-NiO/Ni@C || F-NiO/Ni@C cell achieves 10 mA cm(-2) with an ultra-low cell voltage of 1.37 V, outperforming Pt/C|| RuO2 cell. This study highlights the positive impact of anion doping on interphase synergy and provides useful guidelines for designing monometallic catalysts for UOR and hydrogen generation.

Summary: The addition of PEO in aqueous electrolytes has been found to improve the cycling stability and Coulombic efficiency of Zn anodes, but the overpotential and long-term stability are significantly influenced by different anions. The choice of salt anions in aqueous electrolytes with PEO additives plays a crucial role in tuning the reaction kinetics and stability of Zn anodes.
