Summary: A scalable and easy dip-coating method was used to create a thin CO2-selection layer of Pebax/PEGDA-MXene on a hollow fiber PVDF substrate. The interlayer spacing of the MXene stacks in the coating was designed to be 3.59 angstrom, allowing efficient separation of CO2 from N2 and CH4. CO2-philic nanodomains were constructed in the layer to enhance CO2 affinity, while non-CO2-philic nanodomains promoted CO2 transport. The membrane showed excellent separation performance, surpassing the 2008 Robeson upper bounds limitation.

Summary: Here, a new class of peptidomimetic macrocycles with specific three-dimensional structures and limited flexibility is reported. They are synthesized by combining fused-ring spiro-ladder oligomers (spiroligomers) through solid-phase synthesis. Two-dimensional nuclear magnetic resonance confirms their shape persistency. The triangular macrocycles of adjustable sizes form membranes with atomically precise pores, which exhibit size and shape-dependent molecular sieving towards a series of structurally similar compounds. The exceptional structural diversity and stability of spiroligomer-based macrocycles will be further explored for various applications.

Summary: The substitution of different types of B-site metal cations in the perovskite structure had a significant effect on the catalytic reactivity of the resulting catalysts. In this study, mixed oxides containing B-site substituted CaMFeO3 (M = Cu, Mo, and Co) perovskite catalysts were synthesized, and their catalytic reactivity was investigated in the oxidative degradation of acid orange II (AOII) dye using a Fenton-like reaction. The results showed that CaCuFeO3 exhibited the highest degradation efficiency (97%), followed by CaMoFeO3 (90%), CaFeO3 (64%), and CaCoFeO3 (40%). The enhanced catalytic activity of CaCuFeO3 was attributed to the high reducibility of copper/iron ions within the B-site structure, which facilitated fast redox cycling of the active sites during catalysis.

Summary: Oral vaccine is an ideal non-invasive method to protect communities from infectious diseases. Researchers developed alginate/chitosan-coated cellulose nanocrystal and nanofibril nanocomposites to enhance ovalbumin delivery in the intestine. In vitro and in vivo experiments showed that the nanocomposites generated strong immune responses. However, no significant differences in specific ovalbumin immune responses were observed due to the complexity of the small intestine.

Summary: Forward osmosis (FO) is a promising technology in wastewater treatment, but reverse solute diffusion (RSD) is a challenge in this process. Conventional strategies focus on reducing the amount of reverse solutes, but doubts have been raised about coping with already occurring reverse solutes and utilizing RSD to improve the FO process. This review discusses the state-of-the-art applications and benefits of RSD, as well as important considerations in utilizing RSD for water and wastewater treatment.

Summary: This study evaluated the characteristics of indica rice kernels (IRK) and flour (IRF) annealed under different conditions, and determined the quality of rice noodles made with these annealed IRK and IRF. Annealing increased the paste viscosity of IRK while decreasing that of IRF. Both annealed IRK and IRF showed increases in gelatinization enthalpy change and relative crystallinity. Annealed IRK noodles exhibited denser pores, while annealed IRF noodles exhibited a looser microstructure. With increasing annealing temperature and time, both annealed IRK and IRF noodles showed enhanced tensile properties.

Summary: In this study, we investigate the transport of three typical anions under confinement and reveal that dehydration and related ion-pore interactions play a crucial role in anion-selective transport. We show that strongly hydrated ions have hindered transport due to their enhanced ion effective charge, while weakly hydrated ions have greater permeability. Our findings suggest that precisely regulating ion dehydration can enable the development of ideal ion-selective membranes.

Summary: Considering the renewability and chemical versatility of natural biopolymers, there is a high demand for innovative solvation processes to efficiently disrupt the native supramolecular structures of natural polymers for their modification, derivation, and materials fabrication. This study compares the structural disorganization behavior of different starches in an aqueous ionic liquid, and finds that A-type starches are more susceptible to structural disruption than B-type starches. The ease of starch gelation in the aqueous ionic liquid is not determined by amylose content, but by the compactness of the granule surface.

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.
