Summary: This study presents different Generalized Double Porosity Models for anomalous fluid flow in fractured porous media and discusses their applications in transient production decline. It explores the effects of subdiffusive and superdiffusive flows in fracture networks, coupled with subdiffusive transport inside the matrix, and provides insights into identifying these types of flow in geological formations. Additionally, it discusses different interpretations of model parameters for estimating the length scales of system main heterogeneities and shows that superdiffusive flow regimes could result from highly heterogeneous porous systems with scale-free permeability distributions. Finally, it demonstrates that the use of non-local models discussed here allows for a novel way to construct effective single porosity models for describing double porosity systems over the long term.

Summary: Experimental results showed that the internal and inter-aggregated pore spaces of the medium had an impact on bacterial transport and retention under unsaturated flow conditions. Capillary energy was found to be higher than other forces at the air-water-solid interfaces, but it was not the main driving force for bacterial deposition.

Summary: The complexity of food materials lies in their hygroscopic, amorphous, heterogeneous, and porous structure. Understanding the microstructure and its changes during food processing is crucial for optimizing food processes and ensuring food quality. This review critically assesses the factors that influence microstructure modification in various food processing techniques. It suggests that a porous media framework can provide a deeper understanding of the evolution of food microstructure during processing, aiding in process optimization and the development of novel and hybrid processes.

Summary: Hierarchically porous titania beads with and without amine functionalisation were developed as adsorbents for highly toxic As(V) removal from acid mine drainage (AMD)-affected environments. The beads showed selective removal of As(V) over other competing elements, with different adsorption mechanisms for Fe(II)/Fe(III). The adsorption capacity of As(V) decreased in real AMD solutions, and non-functionalised titania beads were considered preferable for As remediation due to their greater selectivity. Porous titania beads with functionalisation offer a promising and flexible technology for remediating AMD-affected environments.

Summary: The stoichiometry of hexacyanoferrate materials affects their porosity properties and CO2 capture applications. Varying amounts of Co ions and oxidation states of transition metals affect the structures of mesoporous K or Na-cobalt hexacyanoferrates (CoHCFs) and CO2 removal. The results demonstrate that CoHCFs have practical implications in CO2 capture and flue gas separations.

Summary: The process of transport and trapping of arsenic ions in porous water filters is treated as a classic mass transport problem, with modeling conducted using the convection-diffusion equation at the pore scale. The upscaling reveals two possible forms of macroscopic equations for predicting arsenic concentrations in the filters, with the introduction of an additional transport coefficient known as the adsorption-induced vector being a key finding. This theoretical effort represents the first detailed micro-macro coupling in modeling the transport of arsenic species in water filters.

Summary: This work presents two synthesis approaches for mesoporous magnesium carbonates that mineralize carbon dioxide, resulting in environmentally friendly carbonate materials without the use of cosolvents. One synthesis method produces nonequilibrium crystal structures with acicular crystals branching bidirectionally, while another method using supercritical carbon dioxide produces a hydrated magnesium carbonate with smaller pores and high surface area, suitable for adsorption and capillary transport, as well as potential use for carbon capture and sequestration.

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.
