Summary: Layered transition metal chalcogenides have potential applications in large-sized Na+/K+ energy storage technologies due to their large ion transport channels and high specific capacity. However, their slow reaction kinetics and huge volume expansion lead to undesirable electrochemical performance. Various strategies have been explored to improve the performance of MX anodes, such as metal-organic assembly, nanostructural engineering, combination with carbon materials, and component regulation. This review provides a comprehensive overview on the synthesis of MX nanostructures using the metal-organic assembly strategy, discusses the preparation routes and structure evolution, and reviews the relationship between the structure and the electrochemical performance, as well as the energy storage mechanism of Mo-, W-, Sn-, and V-based chalcogenides.

Summary: P2 and O3-type sodium layered oxides (NaxTMO2) are considered as the most promising cathodes for sodium-ion batteries. The P2-type oxides outperform O3 in terms of fast sodium diffusion and high-rate kinetics. The P2-structure, however, has a low initial charge capacity due to sodium deficiency, which limits its practical application. In addition, P2-O2 phase transition and Na+/vacancy ordering degrade the cycling performance. Dual doping strategy, such as Li-Cu dual doping, can mitigate these issues and improve the performance of P2-type cathodes.

Summary: Recent studies have shown that 2D materials, such as siloxene and germanane, can exhibit excellent performance as electrodes in alkali metal ion batteries. The improved electrochemical behavior of these materials is likely due to their limited volume change during charge and discharge, which is based on an intercalation mechanism rather than alloying. To combine the cheapness of Si and high electronic conductivity of Ge, we propose a new series of layered materials called siliganes, which are 2D Si-Ge composites. Among them, siligane_Si0.1Ge0.9 demonstrated the best electrochemical performance in Na- and K-ion batteries.

Summary: In recent years, layered oxides have been widely studied as promising cathode materials for sodium-ion batteries. However, complex phase transitions during charge-discharge process negatively impact their electrochemical performance. High-entropy layered oxides, with 2D ion migration channels between layers, show improved cycling performance. This paper reviews the research status of high-entropy layered oxides in sodium-ion batteries, focusing on the connection between high-entropy and layered oxide phase transitions during electrochemical charging and discharging, and summarizes the advantages and challenges of future high-entropy layered materials.

Summary: The use of solid-state electrolytes (SSEs) instead of liquid ones shows potential for high energy density and safety in next-generation energy storage devices. However, solid-to-solid contact poses challenges to the stability of the electrode/electrolyte interface. In this study, a facile treatment using the dip-coating technique was demonstrated to modify the LLZT/Li interface by forming a MgO interlayer. The modified interface showed significantly reduced interfacial resistance and the assembled Li symmetrical cell exhibited high critical current density and long cycling capability. Full cells based on the LLZT@MgO electrolyte showed excellent cyclability and high rate performance.

Summary: This study examines a Hamiltonian model for the propagation of internal water waves interacting with surface waves, a current, and an uneven bottom. By using the Dirichlet-Neumann operators, the water wave system is expressed in Hamiltonian form, allowing for the determination of the motions of internal and surface waves. Through appropriate scaling of variables and the Hamiltonian perturbation theory, a KdV-type equation with variable coefficients dependent on bottom topography is derived to describe the internal waves.

Summary: This study investigates the O-2 adsorption and reduction on cobalt porphyrin (CoOEP) and phthalocyanine (CoPc) using in situ electrochemical scanning tunneling microscopy (ECSTM). Results show higher ORR activity of CoOEP compared to CoPc. Molecular-level imaging reveals that O-2 adsorbs mainly on Co-II sites and exhibits higher contrast in ECSTM images on CoOEP compared to CoPc. The dynamics of O-2 adsorption are quantitatively measured, with CoOEP exhibiting higher binding dynamics and lower Co-O dissociation barriers compared to CoPc.

Summary: In this research, a metaverse-enabled road maintenance system based on cyber-physical-social systems (CPSSs) is proposed, which fully utilizes the information of CPSS and the functions of road systems in the virtual world of the metaverse. An adaptive and information-preserving data augmentation (AIDA) algorithm-based crack detection algorithm is also proposed to enhance the detection performance of small targets in uncertain environments. The research can also be applied to the traffic metaverse by embedding a traffic flow prediction module in the algorithm. Experimental results show that the proposed algorithm outperforms other state-of-the-art algorithms in road damage detection tasks under different noise and weather conditions.

Summary: This study assessed nutritional and flavor differences in two components, shoot flesh and diaphragm, of two Phyllostachys species and analyzed any positional variation. The results showed that shoot flesh contained higher levels of protein, starch, fat, and vitamin C. On the other hand, the diaphragm had comparable levels of total acid, oxalic acid, and tannin in both species. Our findings suggest that bamboo shoot quality is affected by flavor compound differences, and interspecific and shoot components interact.

Summary: The in situ electrochemical scanning tunneling microscopy (ECSTM) study of O2 adsorption and reduction on cobalt porphyrin (CoOEP) and phthalocyanine (CoPc) is reported. CoOEP exhibits higher ORR activity than CoPc according to electrochemical measurements. Self-assembled CoOEP and CoPc monolayers on Au(111) substrates are observed at molecular resolution by ECSTM. O2 adsorbs on CoII sites and has high contrast in ECSTM images for both CoOEP-O2 and CoPc-O2 complexes. The surface coverage of CoOEP-O2 is approximately 1.4 times higher than that of CoPc-O2. The dynamics of O2 adsorption, quantitatively measured by potential step experiments, indicate higher dynamics and lower barriers for Co-O dissociation on CoOEP compared to CoPc.
