Summary: This article presents an electrochemical-electrophysiological multimodal biosensing patch based on MXene/fluoropolymer nanofiber-derived hierarchical porous TiO2 nanocatalyst interconnected 3D fibrous carbon nanohybrid electrodes. The nanohybrid electrode is produced via a one-step laser carbonaceous thermal oxidation, resulting in excellent electroconductivity, rich active edges, and abundant support for enzyme immobilization. The nanohybrid modified biosensing patch integrated into textile demonstrates simultaneous and precise monitoring of sweat glucose with pH adjustment and electrocardiogram signals. This novel approach opens up possibilities for controlled investigations, functionalization, design options, and mass manufacturing capabilities in real-world applications.

Summary: Piezo-photocatalysis is a novel approach that utilizes nanohybrids consisting of piezoelectric and photocatalytic materials to enhance advanced oxidation processes under both light and mechanical energy. This study investigates the efficiency of piezo-photocatalysis in the degradation of Rhodamine-B dye and Phenol pollutants using ferroelectric-semiconductor nanohybrids (BaTiO3-Ag2O). By activating persulfate and examining the role of free radicals using quenchers, the authors confirm the improved performance of piezo-photocatalysis. The study also reveals the removal mechanism of Rhodamine-B using HPLC and EPR techniques. Overall, combining piezo-photocatalysis with persulfate activation offers a promising strategy for effectively treating complex molecular pollutants in industrial wastewater.

Summary: The study demonstrates that electrically poled ferroelectric matrix enhances localized magnetostrictive deformations in a ferroelectric-ferrimagnetic composite. Dy-modified ferroelectric ceramics exhibit ferrimagnetic DyIG as precipitates with a macroscopic strain almost 50% of the pure DyIG strain. This amplification of the localized magnetostrictive deformation is caused by the motion of ferroelectric-ferroelastic domains in the poled ferroelectric matrix.

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.
