Summary: Metal-organic frameworks (MOFs) are widely used as supporting materials for electrochemical sensing applications. In this study, Ag nanoparticles were incorporated into a Bi-BDC MOF and used for the detection of hydrogen peroxide (H2O2). The Ag-Bi-BDC MOF showed excellent electrocatalytic activity towards H2O2 detection, thanks to the strong binding interaction of Bi3+ with H2O2, the high porosity of the MOF, and the catalytic activity of Ag particles. The fabricated sensor exhibited a wide linear range, high sensitivity, short response time, and low detection limit for H2O2, as well as good selectivity, stability, and reproducibility. The sensor also showed promising real-time application in detecting H2O2 secreted from cancer cells.

Summary: Using simple deformable triblock Janus colloids, increasing particle softness enhances the self-assembly and photonic bandgap performance of the structures. Direct pyrochlore lattices formed from overlapping soft particles exhibit larger photonic bandgaps than nonoverlapping structures, and proper overlap caused by softness can significantly improve the photonic properties of the structures.

Summary: Magnetic colloidal chains are a versatile microrobotic system with promising applications, known for their biocompatibility and ease of manipulation under magnetic fields. The synthesis of these chains involves controlling their quality, length, and flexibility through various parameters such as linker concentration, reaction temperature, and magnetic field strength. The research findings show that the fabrication process of these chains can be accurately described by the Flory-Schulz model, resembling step-growth polymerization. Furthermore, under optimized conditions, long and flexible colloidal chains with significantly reduced bending modulus compared to previous studies have been successfully synthesized, demonstrating potential for investigating actuation, assembly, and folding behaviors of these polymer analogues.

Summary: A simple filtration method is reported for the fabrication of salt-induced nanoporous gold electrodes (SINPGEs) from gold nanoparticles (AuNPs). This method utilizes sodium chloride (NaCl) to trigger the aggregation, sintering, and deposition of AuNPs on polyvinylidene fluoride (PVDF) membranes, resulting in the scalable fabrication of flexible SINPGEs with high conductivity, good mechanical property, large surface area, and low cost. The nanoporous structure of SINPGEs improves the electrochemical responses of various species, and the passivation effect of chloride ions on the oxidation of hydrogen peroxide can be repressed by electrochemical activation.

Summary: This paper introduces a method for better describing time series of counts with characteristics of over-dispersion, asymmetry, and structural change. By using a random coefficient integer-valued threshold autoregressive process and conducting Bayesian empirical likelihood inference, the model parameters are obtained. The complexity of Bayesian calculation is greatly simplified by normalizing approximation of the nonparametric likelihood. Finally, the effectiveness of the proposed method is verified through simulations and an empirical analysis of the meningococcal disease data set in Germany.

Summary: This study proposes a novel method, called adaptive multivariate chirp mode decomposition (AMCMD), to address the challenges of prior knowledge requirement, narrowband limitation, and mode mixing in existing multivariate signal decomposition methods. The method captures time-varying joint modes in a recursive framework and uses demodulation techniques to convert wideband signals into narrowband characteristics. The effectiveness and superiority of the method are demonstrated through numerical examples and real-world time-varying vibration signal analysis.

Summary: The study establishes a novel postfunctionalization strategy to improve the anticoagulation and endothelialization properties of bioprosthetic heart valves (BHV). By modifying the BHV with metal-phenolic networks (MPNs) and anticoagulant recombinant humanized type III collagen (rhCOLIII), the negative effects such as thrombosis and calcification were reduced, and the service lifespan of BHVs was enhanced. The strategy shows great potential in clinical applications and provides a simple solution to enhance the function of BHVs after implantation.
