Summary: There is an urgent need for more efficient technologies to mitigate climate change, such as the separation and capture of CO2 from flue gas. This work explores light gas separation based on a series of novel Organic Ionic Plastic Crystals (OIPCs) and polymer composites with the advantage of competitive and tuneable performance. The study found that the nature of the polymer has a strong impact on separation performance, with PVDF demonstrating more advantageous properties than PEO. Each OIPC also responds differently to a given polymer type and ratio.

Summary: The addition of nanoparticles as fillers can effectively modify the dynamic conditions and prevent crystallization in polymer composites. In this study, composites were prepared using (PEO)(4)CF3COOLi electrolyte and multi-walled carbon nanotubes (MWCNTs) through a solution method. Experimental results from DSC analysis and infrared spectroscopy confirmed the formation of the new composite. Impedance spectroscopy analysis showed a significant decrease in resistance, attributed to interactions between the polymer's oxygen, salt's Li+ cations, and the electrolyte with the MWNTs. At a concentration of 2.0 wt.% MWCNT, a dc conductivity value of 8.42 x 10(-4) S cm(-1) was achieved at room temperature. The results suggest that these membranes can be utilized in technological devices such as batteries and gas or moisture sensors.

Summary: Using powder X-ray diffraction and AC impedance spectroscopy, it was found that the superprotonic CsH2PO4 (CDP) phase can be stabilized at 250 degrees C when sealed in dry air or inert gasses. The proton conductivity of CDP remains constant for at least 10 hours under these conditions. However, removing the gas from the chamber leads to a significant drop in proton conductivity.

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.
