Summary: This study investigates the influence of xylene activity on the vapor and liquid permeation/separation performance of b-oriented MFI zeolite membranes. The results showed that the permeance and separation factor increase with temperature, but decrease with increasing xylene activity. B-oriented MFI zeolite membranes exhibit better vapor permeation/separation performance compared to randomly oriented membranes, and show less negative effect of xylene activity on separation factor. However, both types of membranes show poor separation factor when operated in the pervaporation mode.

Summary: This paper presents a theoretical approach for the pressure dependence of gas permeation flux in dual-phase ionic-conducting membranes, using CO2 permeation in samarium-doped-ceria/molten-carbonate membranes as an example. The model shows that gas permeation is controlled by the materials' intrinsic conductivities and the geometric factors of each phase. The topological structure, which is determined by synthesis method and conditions, can lead to different pressure-dependent flux equations.

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.

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.
