Summary: The selection of an appropriate matrix for amorphous extrudate in hot-melt extrusion involves studying the solid-state properties of drugs and polymers, understanding drug-polymer miscibility and interaction, and screening polymers through thermodynamic phase diagrams. Experimental and theoretical validation studies were conducted to predict thermodynamic phase diagrams and Gibbs free energy of mixing for screening suitable polymers for amorphous extrudate preparation. The process involved using the Flory-Huggins theory, constructing phase diagrams, and determining proper processing parameters for stable extrudates.

Summary: A new fitting model for sorption by glassy polymers is proposed based on the Flory-Huggins equation with a composite formula for the interaction parameter chi. The study shows a correlation between the endpoint of the glass transition region and the position of the maximum of the interaction parameter, providing a theoretical framework for glass transition analysis. Through the analysis, the solvent-induced glass transition temperature variation can be estimated from the sorption isotherm.

Summary: The dissolution-precipitation process is a promising recycling method for polymer waste. This study demonstrates the use of ternary phase diagrams, which provide crucial compositional information, for selecting ideal solvent-nonsolvent pairs. The Flory-Huggins theory, Hansen solubility parameters, and UNIQUAC activity coefficients are used to construct these diagrams. Model validation shows that dynamic light scattering and turbidimetry are preferred over visual inspection. The constructed phase diagrams for different solvent-nonsolvent systems are experimentally validated.

Summary: We investigated the thermodynamics of polycarboxylic acids and found that they have similar plasticizing and hygroscopic properties as sugars and polyols. We also discovered a strong non-zero interaction between polycarboxylic acids and carbohydrates, which explains their excellent potential as deep eutectic solvents. Additionally, polycarboxylic acids are useful alternatives to sugar, although their usage is limited.

Summary: Interfacial polymerization (IP) is a fast polymerization technique that has flexible operating conditions and does not require highly pure monomers. However, mathematical modeling of IP reaction, especially for predicting film properties, is challenging due to fast reaction kinetics and complex physicochemical processes involved. This study extends previous work on polyurea and accounts for various processes associated with the interfacial reaction, such as ionic equilibria, mass transfer, and phase separation kinetics.

Summary: This study reports for the first time the extremely high sorption capacity of PDMS rubber for CO2 near the condensation pressure at a certain low temperature (-3 degrees C), with a sorption enthalpy of 9.3-10.8 kJ mol-1. The sorption isotherms were evaluated using the Flory-Huggins equation, and the resulting parameters were used to estimate the solubility parameter (SP). The CO2/CH4 and CO2/N2 selectivities were found to be 9.6-44 at 100-3000 kPa, which were significantly higher than those of activated carbon.

Summary: In this work, thin film nanocomposite (TFN) membranes of super-glassy polymer PIM-1 containing zeolitic imidazolate framework-8 (ZIF-8)/graphene oxide (GO) composites (ZG) have been prepared. These membranes achieve higher flux and improved separation factors compared to bare PIM-1 membranes. The excellent performance is attributed to the defect-free PIM-1 active layer and the hydrophobic nature of the ZG fillers.

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.
