Summary: This study investigates the influence of micro-cracks on the fracture and deformation of bio-filament networks through computational analysis. It is found that the presence of micro-cracks can change the fracture path and ductility of the network, resulting in an increased fracture energy of the material. Interestingly, the maximum fracture resistance is achieved when the crack length is a few times the network pore size. This research enhances our understanding of cytoskeleton performance and provides valuable insights for the development of high performance biological materials in the future.

Summary: The effect of cross-linking length on the absorption characteristics of polyaspartic acid sodium (PAspNa) was investigated by using different concentrations of diamine cross-linking agents with carbon chains of varying lengths. It was found that the absorbency of PAspNa was optimum when the alkyl chain length was at an intermediate level. The successful cross-linking reaction was confirmed using FT-IR spectroscopy, and the degree of cross-linking and the ideal concentration for maximum water absorption were determined.

Summary: The study developed supramolecular structures using graphene and carbon quantum dots and conjugated polymer chains, finding that GQD/PBT-DNT short chain and CQD/PBT-DNT short chain systems performed the best, while long chain systems had poorer performance. Shorter chains had a better chance of arranging on quantum dot nanoparticles, with GQD-based nano-hybrids outperforming CQD-based ones due to their flat and disc-like structure enabling better assembly of conjugated chains.

Summary: Superabsorbent polymers (SAPs) are being extensively researched in various fields due to their excellent water-absorbing abilities. Cross-linkers, including chemical and nanoparticle cross-linkers, play a crucial role in determining the water absorption performance of SAPs. However, the sustainable development of SAPs has been hindered by the limitations of these cross-linkers. In this study, sodium tungstate (STD) was introduced as a new cross-linker to enhance the water-holding capabilities of SAPs. The resulting poly(acrylic acid)/STD SAP exhibited high water-absorbing capacities in different solutions, indicating the potential of STD as a novel cross-linker for promoting the green development of SAPs.

Summary: In this study, different chain structures of PEDOT derivatives were demonstrated to have an impact on thermoelectric properties. It was found that a small amount of three-armed conjugated cross-linker increased the electrochemical charge transport of PEDOT films without affecting their UV-Vis absorbing property. However, at higher concentrations of the cross-linker, the charge transport decreased and the UV-Vis absorbing curve shifted towards the blue end. Additionally, the power factor of the PEDOT-derivative films was improved with a small amount of cross-linker but diminished with higher concentrations, indicating the importance of proper chain structure for thermoelectric performance.

Summary: Self-healable elastomeric materials have been synthesized and used to improve the gas barrier properties of packaging films. Hexa-layer assemblies consisting of inorganic nanoplatelets and oppositely charged polyelectrolytes were developed by sequential depositions. Layer-by-layer technique was then applied to reduce the water vapor transmission rate of the films. The self-healable barrier films recover their initial properties after mechanical damage, and encapsulated organic light-emitting diodes have significantly longer half-lifetime values. This research develops transparent, stretchable, and self-healable gas barrier films for flexible electronic device packaging applications.

Summary: In this study, a 3D transition metal dichalcogenide (TMD)-MoS2 nanoflower grown on a 2D tungsten oxide-anchored graphene nanosheet (MoS2@W-G) was found to be a superior catalyst for the hydrogen evolution reaction (HER) in both acidic and alkaline conditions. The optimized weight ratio of MoS2@W-G achieved low overpotential, small Tafel slope, and high exchange current density in acidic media. The same composite also exhibited stable HER performance using real seawater in both acidic and alkaline media. These findings suggest a new approach for developing 3D/2D TMD/graphene electrocatalysts for HER applications using seawater.

Summary: Binary acceptor alloys based on A''-D'A'D'-A'' small-molecule acceptors were synthesized and blended with polymer PM6 to form ternary blends for organic photovoltaics (OPVs). By varying the ratio of the two acceptors, the ternary blend with one major (BTPO-NF) and one minor (BTPO-F) acceptor component showed the highest device performance. The enhanced photocurrent attributed to the optimized active layer morphology induced by the alloy acceptor structures contributed to the increased power conversion efficiency (PCE) of the ternary-blend device.

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.
