Summary: Nanotechnology is an active research field in materials science, with metal-organic frameworks (MOFs) and graphene oxide (GO) being two important areas of study. MOFs offer a large specific surface area, high porosity, pore size flexibility, post-synthesis modification, and thermal stability. Similarly, GO has a comparable surface area to MOFs and the advantages of amphiphilicity and dispersion in water. The combination of MOFs and GO has attracted attention due to its resemblance to metal ions and organic binding linkers, as well as its superior performance compared to MOFs or GO alone. This review provides a summary of recent research on the properties, synthesis techniques, advantages, challenges, and various applications of MOFs/GO composites, including supercapacitors, gas separation and storage, water purification, sensing, catalysis, and biomedical applications.

Summary: Step-shaped adsorption-desorption of gaseous payloads by flexible metal-organic frameworks can facilitate the delivery of large usable capacities with reduced energetic penalties. The multivariate linker approach is a powerful tool for tuning the phase change behavior of flexible frameworks. In this work, a multivariate framework was developed with a considerably reduced threshold pressure and desirable adsorption-desorption profile for efficient storage and delivery of weakly physisorbing species.

Summary: The design and synthesis of high surface area one-dimensional metal-organic frameworks (MOFs) are crucial for their potential usage in supercapacitor applications. A one-dimensional Ni-MIL-77 MOF with high surface area was synthesized and investigated for its supercapacitor activity. The 1D-Ni-MIL-77 MOF nanobelts showed a surface area of 93.48 m2 g-1 and a specific capacitance of 1376 F g-1. An asymmetric supercapacitor (ASC) was assembled using activated carbon as the negative electrode and 1D-Ni-MIL-77 nanobelts as the positive electrode, achieving an energy density of 25 W h kg-1 at a power density of 750 W kg-1 and retaining 95% of its initial capacitance after 5000 cycles.

Summary: In recent decades, there has been a shift in focus towards hybrid nanomaterial flows due to the increasing energy demand. However, there is still much to be learned about these flows. This analysis examines the non-linear flow and heat transfer towards a moving surface using scaling similarity transformations to convert equations. The study investigates the effect of non-dimensional parameters on skin friction and Nusselt number transfer rate for hybrid fluid (Graphene + Magnesium oxide) and ternary hybrid nanomaterial (Graphene + Zirconium oxide + Magnesium oxide) cases.

Summary: The separation of propane/propylene mixtures is a challenging task in the petrochemical industry. Metal-organic frameworks (MOFs) have been identified as promising materials for this task due to their structural diversity and tunable pore dimensions. However, the low adsorption capacity and slow diffusion kinetics of MOFs have limited their efficiency. In this study, we report the fabrication of nano-sized MOF crystals for propane and propylene separation, which exhibit enhanced adsorption kinetics and improved adsorption capacity compared to micro-sized samples. This represents the highest efficiency among all reported MOF-based splitters for propane/propylene separation.

Summary: This paper investigates the arrangement of closed pores in non-dense solid electrolytes and proposes a partially delocalized model to describe the non-periodical repeating pores. The order parameter S is defined to quantify the degree of order in the pores' arrangement. The study reveals that ordering enhances the ionic conductivity, but a periodic repeating structure can also be used to model the solid electrolyte with a small error margin. Additionally, the study explores the impact of disordering-assisted pore impingement on ionic conductivity, providing guidance for the further functional design of solid electrolyte structures.

Summary: In this study, a simple and effective strategy to facilitate electron transfer to CO2 by introducing oxygen vacancies (O-v) in electrocatalysts is developed. Stirring oxidized eutectic gallium indium is found to be an important pretreatment step for introducing O-v. The oxidized eutectic gallium indium (O-EGaIn) is reduced to oxide-derived EGaIn (OD-EGaIn) during the subsequent CO2 reduction process, with 4 times higher Faradic efficiency for CO production compared to eutectic gallium indium (EGaIn) in a specific electrolyte. XPS results show that the O-v concentration in OD-EGaIn is much larger than that in O-EGaIn and EGaIn samples. Electrokinetic studies and density functional theory (DFT) calculations further confirm that the introduction of O-v facilitates electron transfer, resulting in activating CO2 and forming the key CO2·- radical.

Summary: In this paper, a new high temperature protective gallium coating (O-Ga) is designed to address the poor high-temperature oxidation resistance of tungsten. The O-Ga material is modified with liquid metallic gallium and can be easily printed to form a coating on tungsten surfaces. The coating shows good flexibility and adhesion, and after isothermal oxidation, it forms a protective β-Ga2O3 layer that prevents oxygen contact with the internal O-Ga and W substrates.
