Summary: Urea and phosphoric acid are necessary for the isolation of phosphorylated cellulose nanocrystals (CNCs). This study found that a design of experiments approach allows for a lower ratio of urea to acid and the production of CNCs with high surface charge. This information is instructive for the application of phosphorylated cellulose nanomaterials in areas such as water purification and medical biomaterials.

Summary: By studying the synthesis and properties of partially substituted amylose n-butylcarbamate (ABC) samples, it was found that the samples were soluble in water within a certain range of degree of substitution (DS), and both LCST and UCST type phase separations were observed. Closed-loop phase diagrams for the dual thermoresponsive ABC samples in water were constructed based on turbidity measurements, and the chain conformation of ABC at different temperatures was determined through SAXS measurements.

Summary: This research investigated the influence of cellulose nanocrystal (CNC)-related parameters on the mechanical and desalination performance of a cellulose diacetate (CDA) membrane system. The results showed that different types of nanoassembly were formed in the CDA when using high aspect ratio (HAR) CNCs. The nanocomposite membrane containing 0.50 wt% HAR-CNCs exhibited improved mechanical strength and reduced water permeability/salt rejection tradeoff, indicating the potential for optimizing both mechanical and desalination performance by manipulating the dispersion state of CNC rods in the CDA.

Summary: In this study, a water-soluble polysaccharide (PLP1) was successfully isolated and purified from Pueraria lobata. It was found that PLP1 was composed of specific glycosidic units and exhibited a better free radical-scavenging ability. Moreover, PLP1 effectively protected the liver against acute alcoholic liver disease (ALD) in mice.

Summary: In this study, a multifunctional dual-network hydrogel was designed to treat infectious wounds. The hydrogel, which had good injectability, stability, self-healing, and adhesion, was loaded with MgO/Icariin composite nanoparticles. In vitro and in vivo experiments showed that the nanohybrid hydrogel had multiple physiological functions and could effectively reduce bacterial infection and promote wound healing. This study provides a new paradigm for the design of multifunctional bioactive hydrogels.

Summary: This study investigates the molecular motifs of hyaluronan-peptide interactions using NMR and molecular dynamics simulations. The results show that arginine-rich peptides have the strongest binding to hyaluronan, followed by lysine. Molecular simulations reveal an extended but significant interaction region, especially for arginine, which explains the enhanced binding between hyaluronan and positively charged arginine-rich proteins.

Summary: The study designed porous membranes with numerous pores that enable fast molecular transport. It was found that the orientation of molecules in the pores is affected by the interactions between polar solvents and hydroxyl groups. In contrast, nonpolar molecules exhibit different transfer behaviors.

Summary: This study demonstrates the fabrication of PA-doped P-PBI membranes using a cost-effective sol-gel process. The mechanical properties and proton conductivity of sol-gel membranes were found to depend on polymer content, and a sol-gel N-PBI membrane achieved a maximum tensile strength of 7.0 MPa and a maximum proton conductivity of 205 mS/cm. The ADL-controlled re-doped sol-gel N-PBI membrane showed improved proton conductivity and fuel cell performance compared to the sol-gel N-PBI membrane.

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.

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.
