Notably, the incorporation of silica particles compensates for the strength loss caused by Lo, while also enabling a breakthrough in overall performance through multiphase synergy. The composite containing 1.5 wt% hydrophobically modified fumed silica (MFS) exhibited optimal properties, with a flexural strength of 144.66 MPa and an impact strength of 31.91 kJ/m 2 , both surpassing those of pure epoxy. Additionally, it had a low friction coefficient of 0.042 and minimal wear loss of 0.024 g/0.5 h. Furthermore, electrochemical impedance spectroscopy confirmed its superior long-term anticorrosion performance, with higher values of R f (1.1×107 Ω·cm 2 ) and R ct (7.2×106 Ω·cm 2 ) compared to the pure epoxy system, representing approximately 3.9 times and 3.8 times the corresponding values of the pure epoxy coating, respectively.

Existing thermal-responsive separators, however, face significant limitations, including high shutdown temperatures, sluggish response times, and inadequate thermal stability, severely restricting their practical deployment. This work proposed a tri-layer smart separator featuring a polybutylene succinate (PBS) thermal-responsive interlayer sandwiched by two robust boron nitride (BN)-enhanced polyvinylidene fluoride (PVDF) outer layers. At approximately 115 °C, the PBS interlayer quickly melts to form a pore-free barrier, effectively blocking lithium-ion transport within minutes. Simultaneously, the thermally conductive PVDF-BN layers retain structural integrity and facilitate efficient heat dissipation, ensuring rapid and stable thermal shutdown. This synergistic multi-layer approach achieves significant improvements in battery safety, demonstrated by: (1) an 11-fold reduction in discharge current compared to conventional polyolefin separators after overheated, (2) a delay of thermal-induced internal short circuit onset by up to 293 min, and (3) enhanced suppression of lithium dendrite growth, resulting in exceptional cycling stability with 95 % capacity retention over 3000 h. Additionally, the increased thermal conductivity (1.51 W/mK) ensures uniform internal heat distribution, minimizing localized hotspots. Our findings present a practical route for developing advanced separators with integrated thermal management capability.","PeriodicalId":237990,"journal":{"name":"Transactions of the Materials Research Society of Japan","volume":"1 5","pages":"100096-100096"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their widespread applications are hindered by issues such as poor cycling performance, limited storage capacity, and low coulombic efficiency. Herein, we propose an innovative “construction-release-repair” design strategy that leverages the synergistic effect of B/N co-doping to address these challenges. By constructing B–N bonds, releasing unstable heteroatoms, and repairing defect sites on carbon layers, this strategy significantly enhances the microstructure and surface engineering of anthracite-based hard carbon. The optimized hard carbon anode delivers high specific capacity of 344.2 mAh g -1 at 0.03 A g -1 with an initial coulombic efficiency of 85.3%, and excellent cycle retention of 88.2% after 500 cycles at 0.2 A g -1 . In-situ Raman spectroscopy and density functional theory calculations reveal that the B/N synergistic effect enhances the sodium-ion adsorption, reduces the diffusion barrier, and enhances reaction activity, facilitating more efficient intercalation and nanopore filling in the low-voltage plateau region. This work offers valuable insights into microstructure regulation and the design of high-performance anode for sodium-ion materials. This work proposes a \"construction-release-repair\" design strategy, utilizing the synergistic effect of B/N co-doping to enhance the microstructure and surface engineering of anthracite, resulting in coal-based hard carbon with high initial coulombic efficiency and capacity. DFT calculations demonstrate that the synergistic effect improves sodium ion adsorption, reduces diffusion barriers, and significantly enhances anode reaction activity.","PeriodicalId":237990,"journal":{"name":"Transactions of the Materials Research Society of Japan","volume":"1 4","pages":"100069-100069"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid carbon reinforcements establish two high-speed thermal conduction paths on the surface of the aluminum skeleton, enhancing the skeleton axial transport efficiency. The calculation results of non-equilibrium molecular dynamics (NEMD) reveal that the utilization of an optimal thickness of HCC layers can effectively strengthen the axial thermal conduction flux of the skeletons while minimizing the detrimental impact on radial heat flow from aluminum substrate to CNTs caused by thermal resistance. The composites exhibit the effective thermal conductivity of 43.17 W·m -1 ·K -1 , which is 5.6 times higher than that of the pristine AF. The instantaneous cooling rate of 16.1 K·s -1 and the cooling efficiency of 34.6% demonstrate the superior heat dissipation performance of the composites compared to other similar carbon phase reinforcing heat sinks.

In this work, we propose and demonstrate a conductivity-enhanced strain sensor with molybdenum disulfide (MoS 2 ) compounded as a conductive filler in the hydrogel matrix. MoS 2 not only facilitates the molding of the dual-networked poly(vinyl alcohol) and poly(acrylic acid) but also provides a physical cross-linking point for the hydrogel matrix, which improves the mechanical properties of the hydrogel with tensile strains up to 780%. Upon further immersion in lithium chloride (LiCl) solution, the conductivity of the hydrogel sensors was significantly improved up to 3.88 S m -1 because the intercalation of Li + into MoS 2 induces the synergistic effect of ionic and electronic conductivity. The inherent -OH and -COOH groups in the network made the hydrogels also self-adhesive.

Constructing heterojunctions is a universal method for facilitating charge transfer, but the poor interface matching limits its charge separation and photocatalytic activity. Here, a metal-nickel bridging (nickel interlayer) NiO-Ni-Zn 2 GeO 4 photocatalyst with well interface matching is designed through a partial oxidation strategy. Structure and in situ Raman characterization demonstrate that the nickel interlayer substantially optimizes interface matching and causes the first-order phonon mode transfer from the first-order longitudinal wave to the first-order transverse wave, which implies that NiO acts as the site for hydrogen production and violent surface reaction. Therefore, the nickel interlayer provides a charge transfer channel for carrier separation. Meanwhile, density functional theory calculations prove an optimal hydrogen-oxygen bond-breaking process with 36 % barriers decrease obtained via the effect of nickel interlayer. As a result, NiO-Ni-Zn 2 GeO 4 shows the photocatalytic hydrogen production rate of 206.6 μmol g −1 h −1 , which is over 8 times greater than that of Zn 2 GeO 4 .
