Summary: The magneto-chiroptical properties of Ag/Co composite chiral nanohole arrays (CCNAs) were investigated in this study. It was found that the intrinsic circular dichroism of CCNA samples can be enhanced by surface plasmon resonance when Ag is a major component, while the Co component allows for magnetic tuning circular dichroism. Samples with high Ag concentration exhibited sharper and stronger magnetic circular dichroism, indicating the potential for large-scale active chiroptical metasurfaces.

Summary: By utilizing enantiopure building blocks, optically active cyclic dimers, trimers, and tetramers were prepared, showing clear Cotton effects and corresponding CPL signs. While the cyclic dimer did not emit CPL, the cyclic trimer and tetramer exhibited intense CPL emissions with a relatively high dissymmetry factor. Their optical and chiroptical properties were reproduced by time-dependent density functional theory calculations.

Summary: This study reports the synthesis of optically active cyclic tetramers from two enantiomerically pure [2.2]paracyclophane compounds. The combination of the absolute configurations of the planar chiral pseudo-ortho- and pseudo-meta-[2.2]paracyclophane units determined the formation of parallel-#- or weave-#-structures. The weave-#-shaped cyclic tetramer exhibited good chiroptical properties and emitted circularly polarized luminescence with high anisotropy and brightness.

Summary: Optical carrier incubation can effectively alter the electron transport properties of semiconductors, allowing for ultrafast manipulation of light at the nanoscale. InSb nanowires, with their high electron mobility and small effective mass, are promising plasmonic materials in the mid-infrared region. By injecting photoinduced electrons, the InSb plasmon can be switched and its frequency can be tuned. These excellent plasmonic properties make InSb nanowires a promising platform for high-speed mid-infrared plasmonic materials in informatic devices.

Summary: Microfibers are a type of pollutants widely found in water bodies. In this study, magnesium hydroxide was used as a coagulant to investigate its performance and mechanism in removing dyes and microfibers. The presence of dyes in the system enhanced the removal of microfibers. The removal mechanisms involved electrical neutralization, sweep flocculation, and adsorption. Higher turbidity and rotational speed improved the removal efficiency. This study provides important theoretical support for understanding the coagulation characteristics and mechanisms in removing complex pollutants in printing and dyeing wastewater.

Summary: The particle swarm optimization algorithm (PSO) is widely used in many fields due to its concise concept and good optimization performance. However, it tends to fall into early convergence when solving complex multimodal optimization problems. This study proposes a new hybrid algorithm called PSOLFWM by combining the PSO algorithm with wavelet theory and levy flight theory to enhance population diversity and searching performance, resulting in higher quality solutions. Experimental results demonstrate that the proposed algorithm outperforms comparison methods in terms of convergence speed and accuracy, and it exhibits higher search stability and anti-interference performance. Statistical analyses further confirm the superiority of the proposed algorithm compared to other methods.

Summary: Metal-octaaminophthalocyanine(MOAPc)-based 2D conductive metal-organic frameworks (cMOFs) with bimetallic characteristics have shown great potential in various applications. This study investigated the metal substitution in isostructural cMOFs with different metal nodes and metal centers, revealing variations in reaction kinetics, particle sizes, crystallinities, electronic structure, and conductivity. Ni-NiOAPc was found to have the highest conductivity among the nine possible combinations. DFT calculations showed that its high conductivity is attributed to high crystallinity rather than the smallest bandgap or highest charge carrier mobility.

Summary: This study introduces a new medium-entropy cathode catalyst, (NbTa)(0.5)BiS3, combined with an ionic liquid-based electrolyte blend, which enables high-rate reversible electrochemistry in Li-CO2 batteries. The Li-CO2 battery with this catalyst exhibits superior performance, with a high current density of 5000 mA g(-1) and a capacity of 5000 mAh g(-1) for up to 125 cycles. The enhanced rate performance is attributed to the greater stability of the multi-element (NbTa)(0.5)BiS3 catalyst due to its higher entropy.

Summary: Magnesium hydroxide has been successfully used for alkaline reactive dye wastewater treatment, but for a wider range of pH values, magnesium hydroxide slurry has the advantage of buffer action. In this study, magnesium hydroxide slurry and non-ionic polyacrylamide (PAM) were used to remove reactive orange dye in aqueous solution. The results show that magnesium hydroxide slurry performs well for reactive orange removal and floc sedimentation in the pH range of 5-12.

Summary: This paper reports a novel Li-Air battery system that operates under high current rates utilizing LiO2 as the main discharge product instead of Li2O2. The high-rate LiO2 battery is achieved through the use of a synthesized SnIrS3.6 cathode catalyst and an electrolyte blend with a SnI2 bi-functional additive. The microporous structure of SnIrS3.6, composed of six- and five-coordinated metal atoms, enables the formation of LiO2 through di-iridium sulfur bridge active sites, preventing disproportionation to Li2O2 and enabling high rates. This finding opens new possibilities for designing advanced LiO2-based Li-O2 batteries.

Summary: The flexibility of metal-organic frameworks (MOFs) is determined by various factors such as chemical composition, topology, particle size, desolvation method, and sample history. Understanding the mechanism behind these observations, particularly the impact of sample treatment history, is still lacking. In this study, the authors investigate the differences in flexibility between desolvated phases of DUT-8(Cu) and other DUT-8 compounds. Theoretical calculations and crystallographic data reveal the preferred formation of interpenetrated confined closed pore phases in DUT-8(Cu), in contrast to DUT-8(Ni, Co, Zn) where closed pore phases are formed.
