Summary: Using CO2-selective membranes based on facilitated transport mechanisms is an energy-efficient approach for hydrogen purification. This study introduced four CO2-philic mobile carriers to a facilitated transport nanocomposite membrane to enhance the CO2/H2 separation performance. The effects of different types and loading of mobile carriers on CO2 permeation properties were investigated, and mechanisms for enhanced CO2 transport in the membrane matrix and nanofiller-polymer interfaces are discussed. With an optimized loading of the selected mobile carriers, the AspK-based membrane doubled the CO2 permeance without sacrificing selectivity, while the ProK-based membrane increased CO2/H2 selectivity by 25% with a slight increase in CO2 permeance. The optimized membranes exhibited separation performances far above the upper bound of CO2/H2.

Summary: By incorporating microporous sodium zeoliteY (NaY) into sulfonated poly (ether ether ketone) (SPEEK), mixed-matrix membranes (MMMs) for CO2/N2 separation were successfully engineered with improved gas separation properties. The even distribution of NaY particles in the SPEEK matrix forming nanochannels enhanced CO2 permeability and selectivity, leading to superior separation performance compared to pristine SPEEK membranes.

Summary: In this study, facilitated transport membranes with PVAm as fixed carrier and various amino acid salts as mobile carriers were synthesized for post-combustion capture. The CO2 separation performance was compared among different AAS carriers, with PZEA-Pro showing the highest effectiveness in facilitating CO2 transport. By adjusting the ratio of PVAm and mobile carriers, the membranes achieved improved CO2 permeance and selectivity, along with good thermal stability and consistent membrane thickness. The membranes developed in this study surpassed the Robeson upper bound and demonstrate great potential for CO2 capture applications.

Summary: A coordination complex between Ag+ ions and olefin molecules in polymer membranes has been developed, resulting in enhanced olefin-paraffin selectivity. The stability of the Ag+ carrier in the membranes has been improved through the use of solid polymer electrolytes containing AgTf2N salt. The membranes exhibit high ethylene-ethane selectivity and permeability, surpassing the upper bound of traditional polymeric gas separation membranes. The observed dual-mode ethylene sorption is explained using a chemical equilibrium model.

Summary: The new model takes into consideration the impact of relative humidity and CO2 partial pressure on gas permeance of AFTMs, which is crucial for their separation performance. The study reveals that variations in CO2 concentration and feed pressure have a greater influence on the separation performance of AFTMs compared to temperature changes. Furthermore, the results of RH in the membrane module can guide the design of membrane area and multistage separation processes.

Summary: Mixed strategy was utilized to design eight kinds of facilitated transport membranes derived from mixed protic ionic liquids for highly efficient ethylene/ethane separation. The membranes exhibited long-term stability and superior ethylene permeability-ethylene/ethane selectivity combinations, breaking through the ubiquitous trade-off effect and offering opportunities to construct advanced membranes for energy-intensive gas separations. The study proved that mixed strategy is a promising platform for high-performance membrane design and structure modification.

Summary: A new modified material BP2533 was developed by modifying Pebax, which showed improved gas permeability for most gases tested except helium. The overall selectivity of CO2 against helium decreased, while the selectivity for other gases with respect to CO2 remained relatively constant, indicating a slight improvement in the ability of the new material to separate CO2.

Summary: Novel printed electronics are expected to be manufactured in large volumes in the future, serving as sustainable alternatives to conventional electronics. This paper focuses on analyzing the carbon footprint of a specific application called 'GREENSENSE' that uses paper-based printed electronics for drug detection and point-of-care devices. Through a life cycle model, the flow of raw materials and energy throughout the production of GREENSENSE is traced, allowing the identification of sustainability hotspots. The analysis reveals that materials such as crystalline nanocellulose and nanosilver contribute significantly to the environmental impact, suggesting the need for their replacement with lower-impact materials, while unoptimized manual and small-scale processes also create process hotspots that can be mitigated through automation and industrial-scale manufacturing.
