Summary: The ultrapermeable benzotriptycene-based polymer PIM-TMN-Trip shows high permeability and CO2/CH4 selectivity, close to the 2019 Robeson upper bound. Upon continuous exposure to CO2, there is an increase in selectivity due to a decrease in CH4 permeability, suggesting a rearrangement of free volume instead of a reduction. Mixed gas permeability experiments with high stage-cut confirm the potential of PIM-TMN-Trip membranes for biogas upgrading.

Summary: Physical aging of glassy polymers reduces permeability over time, hindering the industrial application of high free volume polymers in membrane gas separation. This study demonstrates that storing PIM-1 TFC membranes in methanol vapor effectively retards physical aging and can also be used to refresh aged membranes, with one-week storage being sufficient to recover most of the original CO2 permeance.

Summary: Polymers of intrinsic microporosity (PIMs) with high free volumes, synthesized by incorporating contorted rigid moieties into polymer backbones, have not been industrially used due to fast physical aging despite their exceptional CO2 permeability and selectivity. Recent advances in PIM-based membranes focus on modifying PIM structures for improved CO2 separation performance and reduced physical aging, including strategies such as using suitable side chains, kinked moieties, and stable structures.

Summary: The development of polymers of intrinsic microporosity (PIMs) in the past two decades has created a class of unique microporous materials with both the attributes of microporous solid materials and the solubility of glassy polymers. Due to their solubility in common organic solvents, PIMs are easily processable and have potential applications in various fields such as membrane-based separation, catalysis, and electrochemical energy storage. This review specifically focuses on the dibenzodioxin linkage chemistry of PIMs, discussing design principles, synthetic strategies, characteristic properties, and potential applications. The structure-property correlation of dibenzodioxin PIMs is also analyzed for tailored synthesis and enhanced performances.

Summary: Dibenzomethanopentacene (DBMP) is a useful component for making Polymers of Intrinsic Microporosity (PIMs), which can be used to create efficient gas separation membranes. Compared to the archetypal PIM-1, DBMP incorporation enhances both gas permeability and ideal selectivity. Long-term studies show that DBMP-containing PIMs have less reduction in gas permeabilities during aging, making them attractive for fabricating membranes for efficient gas separations.

Summary: The attention in recent decades has been focused on the optoelectronic properties of indium and gallium chalcogenides, leading to advancements in fundamental and applied science. Group III-VI compounds have laminated structures that can be exfoliated to monolayers. Besides indium and gallium chalcogenides, there are other uncommon compounds in the family of group III-VI compounds, which have various crystal lattices, including layered structures. Aluminum chalcogenides show potential as anodes in batteries and semiconductors. Studies on thallium-based compounds are still exploring their semiconducting and thermoelectric properties. This review aims to summarize the significant features of these unusual materials and propose new studies to revive their potential in future technology.

Summary: In this study, molecular dynamics simulations coupled with umbrella sampling were used to investigate the thermodynamics of exfoliation of a single graphene layer from a graphitic substrate in different solvents. The results showed that both the nanosheet and the substrate exhibited uniform wetting behavior in all tested solvents. Consistent with experimental observations, parallel exfoliation was found to be more favorable than perpendicular exfoliation. All non-water solvents showed comparable effectiveness in graphene exfoliation.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. 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.
