Summary: A quaternized polybenzimidazole (PBI) membrane was synthesized by grafting a dimethylimidazolium end-capped side chain onto PBI. The hybrid membrane exhibited lower swelling ratio, higher mechanical strength, and better oxidative stability compared to the pristine membrane, but the morphology conducive to ion transport was only successfully developed in the pristine membrane. Both membranes showed good alkaline stability at 80 degrees C and demonstrated promising power densities at 60 degrees C for fuel cell applications.

Summary: In this study, the in-plane Young's moduli E-parallel to of 2D lead halide Ruddlesden-Popper HOIPs were systematically investigated. It was found that E-parallel to generally follows the trend of Pb-X bond strength, showing more prominent effects of the metal halide inorganic framework on E-parallel to than E-perpendicular to. The mechanical anisotropy of 2D HOIPs can be tuned based on structural composition, particularly for iodide-based 2D HOIPs, providing valuable insights for materials design and device optimization.

Summary: This study combined an organic-inorganic hybrid composite with gelatin fibers to improve bioactivity and mechanical properties. Loading an acidic drug metronidazole in the gelatin/OI-BM fibers increased bioactivity and induced hydroxyapatite formation. The findings suggest that acidic drugs can significantly enhance the bioactivity of hybrid biomaterials, which is significant for drug-loaded organic-inorganic hybrid biomaterials with poor bioactivity.

Summary: Crystalline materials have been crucial for the development of hybrid organic-inorganic perovskites (HOIPs), leading to interesting applications like solar cells and optoelectronic devices. Recently, the glassy state of HOIPs, which retains the basic building blocks of crystalline HOIPs but lacks long-range periodic order, has been discovered. The emerging family of glasses formed from HOIPs exhibit diverse properties complementary to their crystalline state. This mini review highlights the chemical diversity of 3D and 2D crystalline HOIPs and showcases the production of glasses from these materials, with a focus on achievements in melt-quenched glasses. Our perspective on the future of this new family of materials is also provided.

Summary: This study investigates the shock behavior of three different polymers through molecular dynamics simulations. The results reveal specificities in the shock behavior of polymers, including deviations from the linear relation between shock velocity and particle velocity, as well as differences in shear stress relaxation behind the shock front. It is found that the deviation of the Hugoniot locus is related to the change in the relative contribution of bonding and non-bonding potential energies, while polymers with higher glass transition temperatures exhibit slower shear stress relaxation.

Summary: The difference in leaching of amylopectin from cellulose/amylopectin/1-butyl-3-methylimidazolium chloride ([Bmim][Cl]) blends during regeneration in water and aqueous ethanol has been studied. Molecular dynamics simulations showed that the dissolution and regeneration mechanisms of amylopectin in [Bmim][Cl] are similar to cellulose in ionic liquids. Water regeneration leads to weak electrostatic interactions, resulting in high leaching of amylopectin. In contrast, ethanol-water interactions enhance electrostatic interactions among amylopectin chains, limiting amylopectin leaching in aqueous ethanol.

Summary: Multi-physical fields solution processing strategy is a universal and facile method for preparing various conjugated polymer films and high-performance devices. In this study, we employed a combined microfluidic flow and ultrasonication strategy (FU) for processing CP solutions, and found a pronounced synergetic effect in promoting the pre-ordering of chains in solution. The conformation order and anisotropy of the solution were revealed through various characterizations. A non-classical nucleation model for polymer crystallization in non-equilibrium solution processing was confirmed. The roles of microfluidic flow and ultrasonication in chain aggregation and crystallization were addressed through multi-physical simulations. Compared to pristine solutions, the FU strategy showed improved solution anisotropy and crystallization kinetics, resulting in higher crystallinity in films and increased mobilities in OFET devices. The FU processing strategy provides a universal approach for regulating chain conformation and aggregation in conjugated polymer solutions.
