Summary: The electrolysis community aims to replace the commonly used Ir anode catalyst with a more abundant and stable material like Ni. However, despite Ni being considered a potential replacement, long-term operation reveals that Ni leads to rapid cell failure compared to Ir. This is due to a decrease in anolyte pH and the development of a detrimental chemical environment at the anode.

Summary: This article presents a review of the behavior of uranium nitride (UN) fuels during thermal reactor fuel-based reprocessing. UN is a leading candidate material for Advanced Technology Fuels (ATFs) due to its superior properties, but it has drawbacks in fuel-based applications. The hydrolytic instability of UN can be addressed by introducing protective dopants, but it may impact the reprocessability of spent UN. The review focuses on the management and recycle options for UN fuels post-irradiation.

Summary: This study proposes a novel and environmentally friendly glycinethiosulfate system for gold extraction. The anodic dissolution of gold is mainly influenced by copper(II)-glycine complexes as catalysts, with Cu(C2H4NO2)3- complex enhancing the dissolution rate. The excellent catalytic capability of the Cu(C2H4NO2)3- complex is attributed to its lowest corrosion potential, slighter passivation behavior, and rapid electron transfer. Gold dissolution in the novel glycine-thiosulfate system involves a typical ligand exchange process and the formation of passivation species predominantly by Au(I)-glycine coordination rather than sulfur-containing products.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
