Summary: This study developed a new strategy to enhance the catalytic activity of PILs by regulating their structure. A gradient structure with enriched ionic liquids on the surface was formed by shortening the alkyl chain length of the IL monomer, allowing for better utilization of the active sites. The PIL with a 4-carbon alkyl chain exhibited the best catalytic activity, and further analysis revealed that the release of Br- enhanced the catalytic activity.

Summary: Fiber optics are a promising platform for chemical and biological sensors, but their large aspect ratio poses challenges for microfabrication techniques. In this study, an optical fiber's cleaved end is used as a platform to fabricate cantilever sensors using functional polymers. A through-fiber fabrication process is employed, resulting in high-aspect-ratio polymer beams in a single step. These cantilevers demonstrate dynamic mode application in air and are further tuned for sensing applications such as humidity and chemical sensing using molecularly imprinted polymers.

Summary: The topological geometry of poly(ionic liquid)s has a strong influence on their self-assembly behaviors. This study investigates the effects of cyclic topology on poly(ionic liquid)s by preparing linear and cyclic copolymers and studying their self-assembly phenomena. The results show that the average size of cyclic copolymers nanospheres is 46.2% smaller than linear copolymers nano-assemblies. The authors speculate that the spherical aggregates are formed through a transition from micelles with gradient block-like structures.

Summary: Femur diaphysis fractures usually require surgery and the recovery process can be lengthy. Current assessment methods for femur healing are qualitative and rely on clinical experience. This paper presents a methodology using fibre Bragg grating sensors to assess femur healing, which is validated through numerical analysis and experimental testing with composite femur samples. The results demonstrate that the strain values measured by FBGs can effectively distinguish different healing conditions and may have potential for assessing long bone fractures in patients of different ages and recovery rates.

Summary: This study evaluated the H2O2-tolerance of non-Pt oxygen reduction reaction (ORR) catalysts and investigated the mechanism of H2O2-induced decay. An electrochemical probe method was established to in-operando monitor the H2O2 concentration in non-Pt catalyst layers for the first time, revealing a concentration of 17 mmol/L, which is an order of magnitude higher than that under aqueous electrode test conditions. Based on these findings, a concentration criterion of at least 17 mmol/L is suggested, filling the gap between aqueous electrode tests and real fuel cell working conditions and emphasizing the importance of in-operando monitoring methods.
