Summary: The single-signal colorimetric immunochromatography assay is insufficient for current detection requirements. This study presents the construction of a dual-signal nanocomposite of TA/MoS2 @AuNRs by introducing tannic acid to exfoliate molybdenum disulfide nanosheets and selecting anisotropic gold nanorods as the nanocarriers. The proposed PCICA method demonstrates both colorimetric and photothermal detection of 2-nitrobenzaldehyde semicarbazone with high sensitivity. The immunoassay also shows satisfactory results in measuring SEM in honey samples.

Summary: This article proposes high-selective bandpass filters (BPFs) based on novel multiple-mode substrate-integrated waveguide (SIW) cavities. The multiple-mode SIW cavities are achieved through a folded SIW (FSIW) structure, and their characteristics are analyzed in detail. The resonant frequencies of the TE(102) and T-E201 modes in the normal SIW, as well as the TE1/2,0,1/2, TE1/2,0,3/2, and TE3/2,0,1/2 modes in the FSIW, can be flexibly controlled for designing multiple-mode cavities. The proposed filters have advantages such as high selectivity, compact size, and flexible control over the locations and bandwidth of finite-transmission zeros (FTZs).

Summary: Compared to UV-driven catalysts, the use of sunlight to design efficient visible light catalysts has been less explored. In this study, Fe3O4@ZnO@ZIF-8 three-component core-shell nanoparticles were prepared and their photocatalytic degradation performance was investigated under visible light using Rhodamine B (RhB) as a model contaminant. It was found that Fe3O4@ZnO@ZIF-8 achieved a significant enhancement in the photo-catalytic degradation efficiency with 98% of RhB degraded within 100 min, and a reaction rate constant of 0.0292 min-1. These findings highlight the importance of precise tailoring of core-shell Fe3O4@ZnO@ZIF-8 for achieving desired degradation efficiency of organic pollutants under visible light.

Summary: In this study, three calcium-based metal frameworks were used as precursors to obtain nano CaO through a two-step thermal transition process, and it achieved a fast adsorption capacity of 11.8 mmol g-1. The improvement in cyclic performance was attributed to the gradual transformation of the precursor structure into nanosheets, preventing further aggregation of CaO particles during thermal transition. Pore structure was found to have little influence on the adsorption performance, suggesting that high stability can be achieved by avoiding particle sintering. This study highlights the importance of precise tailoring of nano-CaO for CO2 fast adsorption.

Summary: Current methods for evaluating catalytic degradation reactions of environmental pollutants are limited by intermittent analysis, long turnaround period, and complex sample pretreatment. This study proposes a quantitative time-resolved visualization method that combines sample pretreatment (SDME), fluorescence sensing, and smartphone detection to monitor the progress of catalytic degradation reactions. The feasibility of this approach is validated using the dechlorination reaction of chlorobenzene derivatives. This study not only minimizes the use of organic solvents and achieves efficient time-resolved visualization but also provides a feasible method for in situ monitoring of catalytic degradation reactions.

Summary: The design of binder materials plays a crucial role in improving charge or mass transport in battery electrodes. However, there is a lack of design rules for aluminum-ion batteries. In this study, we applied chloric polycation binders to high-loading graphite cathodes, which enhanced ionic transport through in situ polycation-AlCl4- networks. We found that conjugated unit doping effectively improved adhesive properties and resulted in improved electrochemical performance in terms of area-specific capacity, energy efficiency, rate capability, and long-term cycling stability.
