Summary: Constructing well-designed catalysts by manipulating geometrical and electrical structures is an effective strategy for high-performance lithium-oxygen chemistry. However, achieving high activity and stability in catalysts simultaneously is challenging. In this study, researchers constructed an amorphous oxide/hydroxide with mixed geometrical configurations, which exhibited good catalytic activity and excellent stability. The catalyst's disordered structure provided numerous active sites and facilitated electron transport, resulting in enhanced oxygen evolution reaction and oxygen reduction reaction. The introduction of certain metal ions further improved the catalytic performance by reducing reaction paths and inducing strong electrostatic interactions. The catalyst demonstrated high specific discharge capacity and cycling stability in lithium-oxygen batteries.

Summary: In this study, the effects of three different ionomers (Nafion, Sustainion-type XA-9, and poly(terphenyl piperidinium) (PTP)) on the electrochemical reduction of CO2 using Cu-based electrocatalysts were investigated. It was found that Nafion had little influence on the performance, XA-9 promoted CO formation, and PTP favored hydrogen and formate production. The observed effects were attributed to charge transfer and hydrophilicity/hydrophobicity of the ionomers. This study highlights the structure-sensitive nature of the ionomer-catalyst interaction in CO2RR.

Summary: A novel immobilization-and label-free electrochemical strategy has been developed for the detection of miRNA let-7a using magnetic Fe3O4@hydroxyapatite (Fe3O4@HAP) and the specific adsorption of a duplex structure. With the introduction of the label-free signal molecule Nile blue (NB) and its intercalation into the pDNA-miRNA duplex, a strong sensing signal is achieved without the need for nuclease-assisted cyclic amplification. The sensing system shows a wide linear range (1.0 fM to 100 nM) and a low detection limit (0.051 fM) for miRNA let-7a analysis, and exhibits high specificity.

Summary: The construction of an anti-fouling biosensing interface with inherent electroactivity is advantageous for improving the practicality of electrochemical biosensors. In this study, an electroactive biosensing interface with excellent biofouling resistance ability was developed using a hybrid membrane of Ce3+-poly(dopamine) (PDA) and Prussian blue (PB). The hybrid film not only enhances the hydrophilicity and biofouling resistance ability of the interface, but also acts as the immobilization matrix for the detection of miRNA Let-7a. The biosensor was capable of detecting miRNA Let-7a in human serum samples within a wide concentration range.
