Summary: Silicone rubber (SylSR) matrix composites with shear thickening fluid (STF) microcapsules (SylSR/STF) were fabricated and their mechanical behaviors were characterized. The addition of STF enhanced the impact resistance capacity of the composites and the effect was influenced by the strength of the SR matrix. This study provides a new method for packaging STF and improving the impact resistance behavior of SR, and has implications for the design of STF-related protective materials and structures.

Summary: This paper fabricates silicone rubber matrix composites with shear thickening fluid microcapsules (SR-STF) for advanced impact protective structure. The composites show flexibility at low strain rates but stiffness at high loading rates due to significant strain-rate sensitivity. A hyper-viscoelastic constitutive model is developed based on experimental results to predict the dynamic mechanical behavior of the SR-STF composites and provide practical application methods for STF in soft protective structures.

Summary: The research focused on the arrangement of polyelectrolytes in multilayered PMC capsules and found that the dissociation of different layers is equal regardless of the presence or absence of the shell. The study also revealed that FITC-labeled polyallylamine migrates to the periphery of the microcapsule due to increased osmotic pressure caused by the flow of ions. This effect is enhanced by the lower charge density and less interaction of FITC-polyallylamine with polystyrene sulfonate in the microcapsule structure.

Summary: There is an increasing need to assess the concentrations of Hydrophobic Organic Contaminants (HOCs), including Persistent Organic Pollutants (POPs), in aquatic environments. The hydrophobicity of POPs makes their quantification in water challenging, especially with conventional spot sampling. Passive sampling provides average concentration levels over weeks or months from the quantification of accumulated pollutants during the deployment period. Ethylene vinyl acetate (EVA) and silicon rubber (SR) were compared as monophasic passive samplers in this study to measure dissolved concentrations of HOCs.

Summary: This paper compares the performance changes in silicone rubber in an acidic environment by conducting an aging comparison test on acid-resistant silicone rubber sheet and common silicone rubber samples. The electrical, physical, and chemical properties of the two types of silicone rubber specimens with different aging times are analyzed, revealing the performance characteristics of silicone rubber under a natural acidic environment. The results show that the acid-resistant silicone rubber has higher dry flash voltage and pollution flashover voltage after one year of aging, and both types of silicone rubber maintain good water repellency. The silicone rubber produced according to the self-developed acid-resistant formula indeed delays aging in an acidic environment compared to the common-type silicone rubber.

Summary: The elimination and restriction of PFOA and PFOS have led manufacturers to shift production to substitutes, which still pose threats to the environment. This review summarizes the progress in degrading these substitutes and discusses future prospects for optimization. Differences in the degradation of various substitutes are also discussed to derive designing principles for more degradable F-containing compounds.

Summary: Metal complexes hybridized with conductive supports are desirable catalysts for CO2 electroreduction. In this study, a conjugation-tuning strategy was employed to improve both the intrinsic activity of the complex and the molecule-support interactions by comparing Ni(ii) octabutoxyphthalocyanine and Ni(ii) octabutoxynaphthalocyanine on multi-walled carbon nanotubes. The impaired conjugation in NiPc-B enhances both activity and molecule-support affinity, resulting in higher faradaic efficiencies for CO production compared to NiNc-B.

Summary: Bioinspired smart hydrogels with additive-switchable mechanical properties have been developed using a novel strategy to prepare additive-responsive hydrogels with highly tunable toughness under quasi-isochoric conditions. The softening transition temperature of the hydrogels is tuned through non-covalent interactions between polymer networks and additives. The mechanical behaviors of the hydrogels depend on the type and concentration of additives, and the regulation with additives shows satisfactory reversibility and universality.

Summary: Enzymes, as exceptional natural catalysts, play vital roles in life-sustaining biotransformations due to their exquisite 3D structures. However, their flexibility makes them vulnerable in non-physiological environments, hindering their large-scale industrial applications. This study presents a new bottom-up strategy for enzyme encapsulation using a hydrogen-bonded organic framework (HOF-101), allowing for the encapsulation of various enzymes within a highly crystalline scaffold. Compared to other methods, this enzyme-triggering HOF-101 encapsulation is easy to operate and offers higher loading efficiency, with a well-arranged structure and mesochannels that enhance mass transfer and understanding of biocatalytic processes.

Summary: This contribution comprehensively investigates the biomineralization of zeolite imidazole frameworks for one-step synthesis of an enzyme-MOF biocomposite. The study reveals that the biomineralization ability depends on the ZIF organic linker, and the biocatalytic function is highly related to the ZIF mineral species and their microstructures. Additionally, the protective effect of ZIF mineral on the hosted enzyme is associated with the synergistic effect of size dimension and chemical microenvironment of the ZIF pores.
