Integrating sensing capabilities into structures made of sustainable materials presents significant opportunities for advanced applications. This study develops smart fibre-reinforced composites using sustainable palm leaf fibres (PLF) specifically designed for automotive interior applications such as dashboard panels, door trim, seat structures, and centre console components, as well as aeronautic cabin interiors including wall panels, overhead compartments, seat frames, and galley structures.

The developed composites demonstrate mechanical properties comparable to conventional fibre composites while offering integrated sensing capabilities for structural health monitoring of interior systems. Systematic investigation reveals that 10 wt.% PLF content provides optimal balance between mechanical performance and sensing functionality suitable for interior component requirements. This optimal performance is achieved through the enhanced mechanical properties and surface characteristics provided by PLF incorporation, where the palm leaf fibres promote polar interactions due to hydroxyl groups and other polar functionalities, resulting in improved hydrophilicity and intermediate surface characteristics that are critical for sensing applications. The resulting smart composite exhibits exceptional strain sensitivity with a gauge factor of approximately 27, enabling real-time monitoring. The developed bio-based composites offer significant cost advantages with 30-40% reduced production costs compared to conventional fibre systems and demonstrate scalable manufacturing potential for mass production.

This work demonstrates the successful development of sustainable, eco-friendly materials with advanced sensing capabilities that show promise for automotive and aerospace applications, contributing to a greener and safer future.

将传感能力集成到可持续材料制成的结构中，为先进的应用提供了重要的机会。本研究使用可持续棕榈叶纤维（PLF）开发智能纤维增强复合材料，专门用于汽车内饰应用，如仪表板、门饰、座椅结构和中控台部件，以及航空客舱内饰，包括壁板、头顶隔间、座椅框架和厨房结构。开发的复合材料具有与传统纤维复合材料相当的机械性能，同时为内部系统的结构健康监测提供集成传感能力。系统调查显示，10 wt.%的PLF含量在机械性能和适合内部组件要求的传感功能之间提供了最佳平衡。这种最佳性能是通过PLF掺入提供的增强的机械性能和表面特性来实现的，其中棕榈叶纤维由于羟基和其他极性功能而促进极性相互作用，从而改善亲水性和中间表面特性，这对传感应用至关重要。由此产生的智能复合材料具有优异的应变灵敏度，测量系数约为27，可实现实时监控。开发的生物基复合材料具有显著的成本优势，与传统纤维系统相比，生产成本降低了30-40%，并展示了大规模生产的可扩展制造潜力。这项工作表明，具有先进传感能力的可持续、环保材料的成功开发有望应用于汽车和航空航天领域，为更绿色、更安全的未来做出贡献。

Activating ferroelectricity in two-dimensional (2D) bilayer materials is essential for enabling non-volatile memory and logic functionalities. While interlayer sliding driven by van der Waals interactions can break inversion symmetry, achieving out-of-plane (OOP) polarization through this mechanism remains challenging in highly symmetric 2D materials—particularly those that are centrosymmetric, such as graphene, hexagonal boron nitride (hBN), and transition metal dichalcogenides (TMDs). Here, we propose a general strategy to activate OOP ferroelectricity by intercalating inert atoms into the interlayer space. Using bilayer graphene, hBN, and MoS2 as model systems, we reveal that such intercalation lowers the symmetry from nonpolar D3d to polar C3v, enabling reversible polarization switching via lateral displacement of the intercalants. This resulting semi-sliding ferroelectricity preserves the structural and electronic integrity of the host materials, and features ultralow switching barriers along with atomic-scale dipole control—where each intercalated atom acts as an independent, reversible memory bit. Importantly, the polarization magnitude scales linearly with the electrostatic potential difference across the bilayer, providing a quantitative and tunable design rule. Our findings establish a universal and material-agnostic framework for realizing low-power, ultrahigh-density 2D ferroelectric devices on otherwise nonpolar platforms.

激活二维（2D）双层材料中的铁电性对于实现非易失性存储器和逻辑功能至关重要。虽然由范德华相互作用驱动的层间滑动会破坏反转对称，但在高度对称的二维材料中，通过这种机制实现面外极化仍然具有挑战性，特别是那些中心对称的材料，如石墨烯、六方氮化硼（hBN）和过渡金属二硫属化合物（TMDs）。在这里，我们提出了一种通过在层间空间插入惰性原子来激活OOP铁电性的一般策略。利用双层石墨烯、hBN和MoS2作为模型体系，我们发现这种嵌入降低了从非极性D3d到极性C3v的对称性，通过插入物的横向位移实现了可逆的极化切换。由此产生的半滑动铁电保留了主体材料的结构和电子完整性，并具有超低的开关势垒以及原子尺度的偶极子控制，其中每个插入原子充当独立的，可逆的存储位。重要的是，极化幅度与双层间的静电电位差呈线性关系，提供了定量和可调的设计规则。我们的研究结果为在非极性平台上实现低功耗、超高密度的二维铁电器件建立了一个通用的、与材料无关的框架。

Gallium-based liquid metals are promising for stretchable electronics and beyond. However, their inherent fluidity and weak structural confinement in conventional films often cause leakage and functional failure under extreme deformation. Here, we report ultrathin liquid metal micromesh electrodes fabricated through interfacial self-assembly of microparticles and subsequent laser sintering. These ultrathin electrodes (minimum thickness: 317 nm) exhibit excellent stretchability (up to 1200%) and foldability, maintaining stable performance after 10,000 folding cycles at a 70 μm bending radius. Their mechanical robustness arises from the unique micromesh architecture that disperses strain and alleviates stress concentration. It also confines the liquid metal within defined pathways, thereby preventing leakage (leakage resistance: 968.75 kPa) and ensuring structural integrity under extreme deformation. Moreover, the micromesh structure endows the electrodes with excellent electrical stability (R/R₀ = 1.66 at 300% strain) and translucency. We demonstrate applications of these electrodes in flexible LED arrays, wireless power transfer, and angular sensing.

镓基液态金属在可伸缩电子产品及其他领域很有前景。然而，传统薄膜固有的流动性和薄弱的结构约束在极端变形下往往会导致泄漏和功能破坏。在这里，我们报告了超薄液态金属微孔电极通过微粒子的界面自组装和随后的激光烧结制备。这些超薄电极（最小厚度：317 nm）具有优异的拉伸性（高达1200%）和可折叠性，在70 μm弯曲半径下折叠10,000次后仍保持稳定的性能。它们的机械坚固性源于独特的微孔结构，可以分散应变并减轻应力集中。它还将液态金属限制在规定的通道内，从而防止泄漏（泄漏阻力：968.75 kPa），并确保极端变形下的结构完整性。此外，微孔结构使电极具有优异的电稳定性（在300%应变下R/R 0 = 1.66）和半透明性。我们展示了这些电极在柔性LED阵列、无线电力传输和角度传感中的应用。

A coarse-grained neuroevolution potential (CGNEP) for multilayered graphene based on an ab initio accuracy dataset is developed for mesoscale molecular dynamics simulations. The information loss in coarsening process is discussed and divided into intralayer part and interlayer part. The CGNEP describes the interlayer shear introduced by van der Waals interactions well by modifying the descriptor of NEP. The mechanical properties and vibration frequencies of structures of different sizes are well predicted via CGNEP. Compared with the traditional empirical CG potential, the CGNEP possesses interlayer properties of the structure of graphene and maintains the ability for higher mapping ratio coarsening. The frequencies of a 12-layer graphene membrane with a length and width of 1 μm are directly calculated via the CGNEP with a 64:1 mapping ratio and compared with the experimental results. The proposed CGNEP may be further used for other multilayered CG 2D materials.

基于从头算精度数据集开发了多层石墨烯的粗粒度神经进化潜力（CGNEP），用于中尺度分子动力学模拟。讨论了粗化过程中的信息损失，并将其分为层内部分和层间部分。CGNEP通过对NEP描述符的修改，较好地描述了范德华相互作用引入的层间剪切。利用CGNEP可以很好地预测不同尺寸结构的力学性能和振动频率。与传统的经验CG势相比，CGNEP具有石墨烯结构的层间特性，并保持了更高映射比粗化的能力。利用CGNEP以64:1的映射比直接计算了长度和宽度分别为1 μm的12层石墨烯膜的频率，并与实验结果进行了比较。建议的CGNEP可以进一步用于其他多层CG 2D材料。

Visualization of internal deformation fields in crystalline materials helps bridge the gap between theoretical models and practical applications. Applying Bragg coherent diffraction imaging under X-ray dynamical diffraction conditions provides a promising approach to the longstanding challenge of investigating the deformation fields in micron-sized crystals. Here, we present an automatic differentiation-based reconstruction method that integrates dynamical scattering theory to accurately reconstruct deformation fields in large crystals. Using this forward model, our simulated and experimental results demonstrate that three-dimensional local strain information inside a large crystal can be accurately reconstructed under coherent X-ray dynamical diffraction conditions with Bragg coherent X-ray diffraction imaging. These findings open an avenue for extending the investigation of local deformation fields to microscale crystals while maintaining nanoscale resolution, leveraging the enhanced coherence and brightness of advanced X-ray sources.

The atomic structures, stability and magnetic properties of small Co_n (n = 1–6) clusters on Al-doped Cu(111) surface were investigated by means of Density Functional Theory calculations (DFT + U) and ab initio molecular dynamics (AIMD). Our calculation results indicate that the supported clusters considered are all in two-dimensional structures, which show high stability at temperature up to 600 K evidenced by our AIMD simulations. Furthermore, the relative stability of small Co clusters on Al-doped Cu(111) surface enhances with the increasing of cluster size. Therefore, 1 monolayer (ML) Co film show high stability on Al-doped Cu(111) surface, which is in agreement with experimental observations and high quality Co film may be deposited on Al-doped Cu(111) surface for device applications. Our calculation suggests that AlCu alloy buffer layer only have significant effects on Co film growth at initial stage since the adsorption sites for Co_n (n = 1–5) clusters are different on Al-doped Cu(111) surface (bridge site of two neighboring surface Al atoms) and Cu(111) pristine surface (hcp hollow site), and the adsorption sites of Co_n (n = 6–13) clusters become the same on both surfaces. All the considered systems of Al-doped Cu(111) surface with Co_n cluster adsorbed show ferromagnetic ground states with high magnetic moments and the spin density distributions mainly origin from Co_n clusters and surface Cu and Al atoms have very minor contributions. Co ML film on Al-doped Cu(111) surface exhibits preference of in-plane magnetization, which agrees the behavior of Co films on Cu(111) surface prepared by pulsed laser ablation. Our study can provide basic information of the initial stages of Co film growth and nucleation on Al-doped Cu(111) substrate at atomic level and may shed light on Co/Al-Cu(111) system being potential applications in spintronic devices.

利用密度泛函理论（DFT + U）和从头算分子动力学（AIMD）研究了al掺杂Cu（111）表面Con （n = 1-6）簇的原子结构、稳定性和磁性。我们的计算结果表明，所考虑的支持团簇都是二维结构，在高达600 K的温度下具有很高的稳定性，我们的AIMD模拟证明了这一点。此外，小Co团簇在al掺杂Cu（111）表面的相对稳定性随着团簇尺寸的增大而增强。因此，1单层（ML） Co膜在al掺杂Cu（111）表面表现出较高的稳定性，这与实验观察结果一致，可以在al掺杂Cu（111）表面沉积高质量的Co膜，用于器件应用。我们的计算表明，由于Con （n = 1-5）团簇在Al掺杂Cu（111）表面（两个相邻表面Al原子的桥位）和Cu（111）原始表面（hcp空心位）的吸附位置不同，而Con （n = 6-13）团簇在这两个表面的吸附位置趋于一致，因此AlCu合金缓冲层仅在初始阶段对Co膜的生长有显著影响。所考虑的含有Con团簇的掺铝Cu（111）表面体系均表现出高磁矩的铁磁基态，自旋密度分布主要来源于Con团簇，表面Cu和Al原子的贡献很小。掺杂al的Cu（111）表面的Co ML膜表现出面内磁化的偏好，这与脉冲激光烧蚀制备的Cu（111）表面Co膜的行为一致。本研究提供了在掺杂al的Cu（111）衬底上初始阶段Co膜生长和成核的基本信息，并为Co/Al-Cu（111）体系在自旋电子器件中的潜在应用提供了线索。
