Summary: The structural and surface properties of PErP nanoparticles with different comonomer compositions were studied using Monte Carlo simulation. At higher ethylene fraction in PErP chains, the interior bulk densities of nanoparticles increased and the surfaces became sharper. Chain ends were preferentially segregated at the surface, while the comonomers in the middle position were homogeneously distributed inside the nanoparticles. Chain dimensions and shape changed mostly in the surface region and decreased significantly with higher ethylene fraction.

Summary: Green and sustainable biomass materials based on wood processing residues have great potential as substitutes for petroleum-based plastics. A high-performance bio-based plastic was successfully fabricated using a dual-crosslinking strategy of sodium lignosulfonate (LS) and epichlorohydrin (ECH) modification. The resulting TOLC-LS/ECH film exhibited exceptional tensile strength, thermal stability, water resistance, biodegradability, and mechanical stability. Compared to other sustainable bio-based plastics, this film combines low production cost, high mechanical properties, and excellent thermal stability, making it suitable for mulch, daily packaging, and other applications.

Summary: Starches of different botanical origin, such as potato, wheat, and corn, are cross-linked with epichlorohydrin at various ratios, and the degree of cross-linking is evaluated by solubility in KOH solution and pasting properties. The size of starch microgranules affects the degree of cross-linking, with smaller granules requiring more cross-linking agent for the same solubility or viscosity characteristics. Two methods are discussed for determining the degree of cross-linking, with the alkali solubility method suitable for a wide range, while viscoamylography approach is only effective when the amount of EPI is increased.

Summary: In this study, injectable PNIPAM/PVP interpenetrating polymer networks were fabricated and characterized. The results show that the internal structure of the injectable IPNs can be controlled by adjusting the PVP molecular weight and degree of thiolation. The PNIPAM gelation drives the formation of domains, with PNIPAM mainly located in the PVP-rich domains and PVP entrapped in the PNIPAM-rich domain. Additionally, the structural reconfiguration of the IPNs can be achieved by heating above the volume phase transition temperature of the PNIPAM phase, which is influenced by the molecular weight and thiolation degree of the PVP precursor polymers.

Summary: This study presents a novel design of injectable hydrogels via a Schiff base cross-linking reaction between adipic dihydrazide (ADH)-modified poly(L-glutamic acid) (PLGA-ADH) and benzaldehydeterminated poly(ethylene glycol) (PEG-CHO). The hydrogels showed good self-healing ability and biocompatibility with bone marrow-derived mesenchymal stem cells (BMSCs), promoting BMSC proliferation and deposition of glycosaminoglycans and upregulating the expression of cartilage-specific genes. In a rat cartilage defect model, the hydrogels significantly promoted new cartilage formation, indicating their potential in cartilage tissue engineering.

Summary: Thermoresponsive copolymers were synthesized and their thermoresponsive properties were characterized. The copolymers showed a lower critical solution temperature in water, which depended on the molar fraction of one of the monomers. Block copolymers were also prepared using a surfactant-free emulsion polymerization method, and their thermoresponsive behavior in a confined state was investigated. The nanospheres showed a linear change in hydrodynamic radius with temperature, and the addition of certain salt anions affected the collapse of the nanospheres' corona.

Summary: This study reports on the development of positively charged isoporous block copolymer nanofiltration membranes with designed soft nanochannels. The membranes were obtained through self-assembly and non-solvent-induced phase separation. A versatile post-modification approach was used to engineer well-defined soft nanochannels. The membranes demonstrated the capability to separate mono-/divalent cations based on their ionic size difference, charge, and energy. The selectivity of the membranes was significantly higher in binary-salt systems compared to single-salt systems. The membranes also showed potential for recovering valuable ionic species from water, such as Mg, which is classified as a critical raw material in Europe.

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.
