Summary: Nanopores were created in gas-impermeable GO and functionally activated to prepare hybrid PIM-1/holey GO membranes, which exhibited higher CO2 permeability and CO2/CH4 selectivity than pure polymer membranes. The mitigation of physical aging was significantly improved by using functionalized holey GO nanofillers, maintaining a higher percentage of initial CO2 permeability over time.

Summary: The rational design of fillers and polymers is essential for the fabrication of high-performance mixed matrix membranes (MMMs). In this study, fluorinated metal-organic frameworks (KAUST-7) were blended with a polymer of intrinsic microporosity (PIM-1) to prepare MMMs. The resulting MMMs demonstrated enhanced CO2/CH4 separation performance and improved anti-physical aging property, thanks to the porous nature of KAUST-7 and its strong interactions with PIM-1. The optimized MMMs exhibited a significant increase in CO2 permeability and CO2/CH4 selectivity, indicating their potential for practical CO2 separation applications.

Summary: This study demonstrates the successful incorporation of pyrazole-based metal-organic frameworks (MOF-303) into polymer of intrinsic microporosity (PIM-1) through a physical blending approach, resulting in mixed matrix membranes (MMMs) with remarkable separation performance. The MMMs exhibit improved CO2 permeability and well-maintained CO2/CH4 selectivity compared to unfilled PIM-1 membranes. Notably, the MMMs also display excellent stability, resistance against physical aging, and reinforced resistance to plasticization compared to the control PIM-1 membranes. This research provides a novel approach for the rational design of MMMs in CO2 separation applications.

Summary: CMS/ZSM-5 mixed matrix membranes were prepared and investigated for their morphology and structure. The results showed that ZSM-5 particles were well dispersed in the carbon matrix and maintained their microstructure during pyrolysis. The CMS/ZSM-5 MMMs exhibited outstanding gas permeability without significantly sacrificing selectivity compared to pure CMS membranes. Additionally, the aging of the CMS/ZSM-5 MMMs in a humid environment was studied and the permeability of the aging membrane was partially recovered after thermal treatment.

Summary: Graphene oxide (GO) composite membranes have been widely used in membrane modification due to their excellent properties, such as huge specific surface area, good electrical conductivity, good hydrophilicity, and various functional groups. The addition of GO in membranes has been proven to improve water permeability, molecular selectivity, membrane fouling mitigation, and contaminants decomposition. Recently, the development of laminated GO in membranes has achieved both high selectivity and high water permeability, overcoming the limitations of conventional polymeric or inorganic membranes. This review systematically summarizes the applications of GO composite membranes in three highlighted areas of environmental fields: desalination, gas separation, and wastewater treatment, and discusses the challenges faced with GO composite membranes.

Summary: The study found that MXene-filled membranes allow for much higher loading (up to 20 wt%) compared to GO-filled membranes (up to 5 wt%). Interestingly, dry-state membranes exhibit optimal CO2 separation performance at low loading (1 wt%), while wet-state membranes show increased permeability and CO2/N-2 selectivity at higher filler loadings, contrasting with results obtained under dry conditions. The enhanced CO2 separation performance at high loading under humidification can be attributed to the hydrated interlayer channels of MXene/GO, indicating unique characteristics of MXene in wet-state mixed matrix membranes for CO2 separation.

Summary: Mixed matrix membrane materials (MMMs) are being studied for gas separation, and this research investigates the optimal combination of filler and matrix for maximum selectivity. Computational simulations show that adding a filler with similar permeability to the faster gas in the matrix can result in the highest selectivity change, and these results are compared to analytical solutions from various models. The role of interfacial defects in altering the transport properties of mixtures through the MMMs is also examined.

Summary: In this study, PIM-1 membranes were prepared using a 21-step method via molecular dynamics simulations. The structure and separation performance of these membranes for CO2/N2 mixture were explored. The results revealed that the permeation behavior of CO2/N2 mixture through PIM-1 membrane is dominated by solubility, and the cyano group and terminal hydroxyl groups in the PIM1 chain play important roles in gas adsorption and permeation.

Summary: This study explores the use of graphene oxide laminate coatings to overcome pore wetting issues in membrane distillation. By depositing a graphene oxide membrane on top of a commercial porous polyvinylidene fluoride support and using polydopamine to form a hydrophilic tri-layer membrane, enhanced pore wetting resistance is achieved without affecting membrane flux. Ultimately, a tri-layer immobilized graphene oxide membrane is synthesized with superior performance, enabling membrane distillation for a new range of wastewater applications.

Summary: The vortex ring effect is used to generate three-dimensional assemblies of graphene oxide (GO) flakes in water, which leads to the formation of GO hydrogel and aerogel microparticles with complex shapes. By using electrohydrodynamic VR effect, the real-time self-assembly of GO core-shell hydrogel microparticles with spherical, donut and jellyfish shapes can be observed and controlled. The formation of different shapes is determined by dimensionless Weber and Ohnesorge numbers, and the microparticles can be used for efficient adsorption and removal of anionic contaminants in water with tuneable adsorption capacity.

Summary: Ultra-thin graphene-based membranes are promising for high-performance NEMS devices. However, modeling these membranes is challenging due to their deflection behavior which does not satisfy pure bending or stretching assumptions. In this study, we propose a model based on FvK equations that considers both bending and stretching forces in graphene-polymer heterostructure NEMS membranes. The model is validated by comparing experimental and simulated membrane shapes, and it accurately predicts the capacitance change in deflected GPH membrane devices under varying pressures. This model serves as a powerful tool for designing and developing graphene-based NEMS devices.

Summary: The research found that graphene oxide is a suitable substrate for human sAD-MSC incubation, promoting regeneration of severe peripheral nerve injuries. However, transcriptome changes are minimal, and growth factor gene expression remains unchanged on GO substrates, but NGF and GDNF protein secretion increases at day 3 and 7. In general, GO substrates are compatible with sAD-MSCs primed for peripheral nerve regeneration strategies and protect the cell population in harsh environments.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
