Abstract ：
Entropy theories play a significant role in rotating machinery fault detection. The key parameters of these methods are, however, often selected subjectively based on trial-and-error methods or engineering experience. Unsuitable parameters would result in an inconsistency between the extracted entropy results and the realistic case. In order to address this issue, a complexity measurement method called "swarm intelligence optimization entropy" (SIOE) is proposed, which adaptively estimates optimal parameters using skewness metrics, logistic chaos theory, and African vulture optimization (AVO). By considering the variability and dynamic changes of various signals, SIOE enables the extraction of robust and discriminative dynamic features. Additionally, a collaborative intelligent fault detection method for rotating machinery fault detection is developed, based on SIOE and extreme gradient boosting (XGBoost). This method aims to accurately identify single faults, compound faults, and varying fault degrees within the rotating machinery. Simulation and fault detection experiments on rotating machines demonstrate that SIOE improves recognition accuracy by up to 21.25% compared to existing entropy methods. The proposed intelligent fault detection method improves recognition accuracy by up to 15.71% compared to advanced fault detection methods. These results highlight the advantages of SIOE in complexity measurement and feature extraction, as well as the effectiveness and accuracy of the proposed intelligent fault detection method, in identifying rotating machinery faults.

Abstract ：
Ultrafine silicon carbide (SiC) powders have garnered increasing attention mainly due to their vast potential for diverse applications. In this study, a plasma-enhanced fluidized bed reactor to crack hexamethyldisilane (HMDS) was effectively developed, thereby producing SiC/NC composites with diameters ranging from 10 to 20 nm. This method enabled large-scale and sustainable production of SiC/NC composites. Concurrently, nitrogen doping was finally achieved by introducing ammonia during the plasma process, which increased material defects and thus enhanced electrical conductivity. Moreover, the abundant hydrogen atoms in ammonia modulated the product properties, as evidenced by reduced particle size, enhanced crystallinity as well as decreased free-carbon content. The synthesized composites were applied as anodes in lithium-ion batteries, and their feasibility was confirmed through extensive testing. Notably, SiC-150 exhibited a discharge capacity of 413mAh g−1 after 200 cycles at 0.1 A g−1 and maintained a high specific capacity of 780mAh g−1 even after 800 cycles at 0.5 A g−1. © 2025 Elsevier B.V.

Abstract ：
3d transition metal-based lithium-rich cathodes (LRMNC), exemplified by the chemical formulas Li1+xTM1-xO2 and xLi(2)MnO(3)center dot(1-x)LiTMO2 (where TM represents Mn, Ni, or Co), exhibit markedly higher capacities (similar to 250-300 mAh/g) and energy densities (similar to 1000 Wh/kg) than their conventional counterparts. This enhanced performance is a result of synergistic cationic and anionic redox reactions, particularly those involving oxygen, which significantly boost the cathode's specific capacity and energy density. Nonetheless, LRMNCs encounter formi-dable challenges, including structural degradation, capacity and voltage decay, hysteresis, and sluggish kinet-ics-issues that stem from complex cationic and anionic redox processes (CAR). The interplay between these redox reactions is sophisticated and crucial for optimizing the performance of LRMNCs. Our study offers an in- depth analysis of these processes, highlighting their intricate interactions, and aims to enhance the stability and efficiency of these cathode materials. Additionally, we provide a comprehensive review of the evolution of layered lithium-rich oxide (LLRO) cathodes, detailing the development of CAR processes, their impacts, and potential strategies for improvement.

Abstract ：
Rechargeable graphene-based aluminum-ion batteries (AIBs) are recognized as a promising energy storage system. The impact of the macroscopic morphology of graphene electrodes on electrochemical performance, however, has been minimally explored. Reduced graphene oxide (rGO) was synthesized via a modified Hummers method and hydrothermal reduction, utilizing natural flake graphite as the starting material. The traditional electrode preparation process was employed, where the active material, conductive agent, and binder were combined to form a slurry for coating and subsequent drying, resulting in the rGO electrode. Aerogel-shaped rGO (rGOA) and film-shaped rGO (rGOF) electrodes were additionally crafted through freeze-drying and filtration drying techniques. Among the three distinct rGO electrode morphologies tested as cathodes in AIBs, the rGOF electrode demonstrated outstanding electrochemical characteristics, including a high specific capacity of 149.3 mAh/g at 500 mA/g, a substantial rate performance of 55.3 mAh/g at 10,000 mA/g, and an impressive long-term cycling stability of 94.5 mAh/g with a Coulombic efficiency of 95.8 % at 5000 mA/g after 10,000 cycles. These superior properties are attributed to the rGOF's binder-free, densely packed structure. The findings suggest that the rGOF electrode holds significant potential as a cathode material for AIBs, offering advantages in both scalable preparation and superior electrochemical performance.

Abstract ：
Photoelectronic sensors, such as phototransistors, photoelectronic vision sensors, and photoelectronic memory elements based on low-dimensional nanomaterials and their hybrid structures, have received considerable attention for their unique structure and characteristics. Most studies on photoconductance sensors focus on positive photoconductivity (PPC); however, rare cases exist in which the conductivity decreases under light exposure. Such cases are known as negative photoconductivity (NPC). The integration of NPC and PPC has garnered significant interest for its switchable memorized electron transport mechanism, thus paving a novel way for the creation of nonvolatile memories, photoelectric logic gates, and neuromorphic computing systems. To deepen our understanding of NPC-based photoelectric sensors, we focus primarily on the basic mechanics of NPC effects and explore the related materials, structures, properties, and applications. Then, we highlight the modulation techniques for achieving NPC and PPC switching and discuss the most promising logic and memory applications by integrating the NPC and PPC effects. Furthermore, this study addresses key challenges in research on nanomaterials that exhibit NPC effects, aiming to inspire further exploration of novel, high-performance, and stable photoelectric sensors.

Abstract ：
Anthraquinone derivatives, known for their redox properties, are widely recognized as promising cathode materials for aluminum-ion batteries. This study presents an environmentally benign extraction of aloe-emodin from aloe dry powder, a sustainable and economically viable resource, using ferric chloride as an oxidizing agent in an acidic medium. Emodin and its isomer, aloe-emodin, share a symmetrical polycyclic chemical architecture and carbonyl functionalities, but differ in the position of their hydroxyl groups. The shift of a hydroxyl group from the aromatic ring to the methyl moiety in emodin results in aloe-emodin, enhancing its redox potential. As a cathode material in aluminum-ion batteries, aloe-emodin demonstrates enhanced electrochemical performance compared to emodin, showcasing a high reversible specific capacity of 85.9 mAh/g at 50 mA/g, superior rate capability with 42.0 and 32.0 mAh/g at 1000 and 2000 mA/g, respectively, and remarkable long-term cyclability with a capacity retention of 50.3 mAh/g and a Coulombic efficiency of 99.05 % after 6000 cycles at 1000 mA/g. These findings contribute to a deeper understanding of the design principles for aluminum-ion batteries that leverage anthraquinone-based cathode materials.

Abstract ：
ContextThe rotating arc plasma technique for the synthesis of nitrogen-doped graphene capitalizes on the distinctive attributes of plasma, presenting a straightforward, efficient, and catalyst-free strategy for the production of nitrogen-doped graphene. However, experimental outcomes generally fail to elucidate the atomic-level mechanism behind this process. Our research utilizes molecular dynamics simulations to explore theoretically the formation of radicals during the plasma-driven reaction between methane (CH4) and nitrogen (N-2). The simulations present a complex reaction system comprising nine principal species: CH4, CH3, CN, CH2, HCN, CH, N-2, H-2 and H. Notably, HCN and CN emerge as pivotal precursors for nitrogen doping. Optimal nitrogen concentrations enhance the synthesis of these precursors, whereas excessive nitrogen suppresses the formation of C-2 species, impacting the yield of nitrogen-doped graphene. Conversely, higher methane concentrations stimulate the generation of carbon radicals, augmenting the production of HCN and CN and thus, influencing the properties of the synthesized material. This work is expected to lay a theoretical foundation for the refinement of nitrogen-doped graphene synthesis processes.MethodsIn this investigation, we employed the LAMMPS software package to explore the formation of free radicals during the methane-nitrogen reaction via molecular dynamics (MD) simulations. These simulations were conducted under an NVT ensemble, maintaining a constant temperature of 3500 K with a time step of 0.1 fs over a duration of 1000 ps. To reduce the variability and enhance the reliability of the simulation outcomes, each simulation was meticulously conducted three times under identical parameters for subsequent statistical analysis.

Abstract ：
The LiFePO4 cathode material possesses a low diffusion coefficient and exhibits poor electronic conductivity, respectively due to its uniaxial ion channel and inherent semiconductor properties. To address these limitations, Co and Nb doping emerges as a vital solution owing to their similar ionic radii and stable valence states. In this study, density functional theory (DFT) is employed to investigate the impact of Co and Nb doping on the electrochemical and mechanical properties of LiFePO4. The results reveal that the dopants lead to an expansion in the lattice constant of LiFePO4. Furthermore, doping brings about a significant reduction in the volume change rate (0.3% for Co doping and 1% for Nb doping), resulting in enhanced transmission of lithium ions. Specifically, Co and Nb doping elevate the lithium removal voltage of LiFePO4 from 3.44 to 3.96 V and 3.8 V, respectively. Furthermore, these doping processes enhance the material's mechanical properties. It is worth noting that the doping of Co and Nb reduces the migration barrier and increases the diffusion rate of lithium ions. It is observed that the proximity to the doped ion increases the energy barrier, whereas moving away from the doped ion decreases the energy barrier, emphasizing the significant influence of dopant ions on the local energy barrier. Additionally, after doping, the operating voltage of the battery experiences a significant increase. Overall, the selected elements in this study demonstrate promising potential to enhance the performance of LiFePO4 cathode materials, offering encouraging prospects for future advancements in battery technology.

Abstract ：
As multivalent ion batteries, aluminum ion batteries (AIBs) have broad application prospects. In addition, with the further development of new electrolytes, deep eutectic electrolytes are expected to become a green, inexpensive, safe, and ideal electrolytic liquid system to replace traditional ionic liquid electrolytic systems commonly used in AIBs. Herein, we prepared an AlCl3-acetamide (AcAm) electrolyte and systematically analyzed its ion transport capacity at different molar ratios of its components. Consequently, a compositional ratio of 1 : 1.4 of AcAm : AlCl3 provided the best ion transport capacity, exhibiting an exceptional electrochemical performance with high reversible capacity, excellent rate performance, and excellent cycling performance. The graphite material in the electrolytic liquid system showed a typical charge storage mechanism dominated by diffusion-controlled processes, indicating that the charge storage behavior of the graphite electrode in this type of electrolyte battery is dependent on ion intercalation. Additionally, the main structure of the graphite material showed little to no change during a long electrochemical test cycle, suggesting its high structural stability. This research shows that the amide electrolyte has great potential for electrochemical application and broad application prospect.
