Summary: Membrane separation technology is an effective method for CO2 reduction, saving 90% of energy consumption. However, the CO2 separation performance of gas separation membranes is limited by the trade-off between permeance and selectivity. In this study, g-C3N4-GO/Pebax-1657 mixed matric membranes were prepared by combining graphene oxide (GO) nanosheets with g-C3N4 nanosheets as composite fillers. The prepared membrane exhibited excellent thermal stability and mechanical properties, and showed superior CO2 separation performance.

Summary: The incorporation of porous nano-fillers into mixed matrix membranes (MMMs) significantly enhances the CO2 separation efficiency. F-Ln (Ln = La, Ce, Pr, Nd) nanosheets with mesoporous structure were used as fillers in Pebax & REG;1657 matrix to improve CO2 separation performance. The F-Ln nanosheets were uniformly distributed in the membrane, and the mesoporous structure facilitated rapid CO2 transport in Pebax/F-Ln MMMs. The smaller pore diameter of the nanosheets, especially F-Nd, showed the best CO2 separation performance.

Summary: In this study, highly porous and mechanically stable ZnO foams, called MolFoams, were prepared by doping with Co, Ni, or Cu salts. The doped foams showed improved stability and reduced leaching of Zn2+ after irradiation, but with a decrease in photocatalytic activity.

Summary: Plasma-assisted catalytic CO2 methanation is a promising method for utilizing CO2 under mild conditions, and it requires rational design of catalysts and processes. In this study, bimetallic NiFe_n/(Mg, Al)Ox catalysts were developed and the effects of Ni and Fe atomic ratio and reduction temperature were systematically investigated. The results showed that higher reduction temperature promoted the formation of Ni3Fe alloy and surface oxygen vacancies, leading to increased CO2 adsorption ability. The NiFe0.1/(Mg, Al)Ox-800 catalyst exhibited excellent catalytic performance with 84.7% CO2 conversion and 100% CH4 selectivity in plasma-assisted catalysis. Additionally, response surface methodology (RSM) was employed to optimize the plasma-catalytic CO2 methanation process for the first time.

Summary: Based on published experimental data, empirical correlations were developed in this study to predict the hydrodynamic performance and mass transfer efficiency of SiC ceramic foam monolithic trays. These new correlations take into account the tray structure parameters (such as open cell diameter and tray thickness) and the operation conditions (such as liquid and vapor flow rates), and the predicted results agree well with the experimental results. The availability of such empirical correlations can be beneficial for the chemical engineering design of practical distillation processes based on SiC foam monolithic trays.

Summary: This study investigates the impact of dysregulation of hydrogen sulfide (H2S) production on the senescence of alveolar type II (AT2) cells and the communication between AT2 and fibroblasts. The results show that H2S can attenuate AT2 cell senescence and suppress senescence-associated secretory phenotype (SASP) of AT2 cells via the inhibition of p53/p21 pathway, leading to the suppression of fibroblast proliferation and transdifferentiation. The findings suggest that abnormal H2S synthesis may contribute to the development of pulmonary fibrosis by promoting the activation loop involving senescent AT2 cells and activated fibroblasts.

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.
