Real‐Time Structural Monitoring and Effective Interlaminar Reinforcement of Carbon Fiber Composites Hybrid With Surface Modified Non‐Woven Silk Fabric ABSTRACT Carbon fiber reinforced polymer (CFRP) composites are widely used in aerospace applications, necessitating advanced structural health monitoring (SHM) techniques to ensure their integrity and safe operational performance. This study specifically introduces an innovative SHM approach using fiber hybrid reinforcement for CFRP composites during flexural deformation. MXene and carbon nanotubes modified non‐woven silk fabric (MC‐nSF) was prepared by the surface micro‐dissolution and adhesion (SMDA) process. The resultant MC‐nSF has demonstrated exceptional strain sensitivity, making it suitable for SHM applications. The MC‐nSF layer was strategically positioned within CFRP composites via the vacuum‐assisted resin transfer molding (VARTM) process to evaluate their interlaminar properties and responsiveness. Notably, the resistance change rate (Δ R/R 0 %) of CFRP composites incorporating the MC‐nSF layer experienced significant increases of 10.95% in the interlaminar shear (ILS) test and 5.17% in the end‐notch flexure (ENF) test before damage. The analysis of Δ R/R 0 % trends allowed for precise identification of crack initiation, facilitating effective monitoring of crack propagation. Additionally, integrating the MC‐nSF layer significantly improved the interlaminar properties of the CFRP composites, with ILS strength and Mode II interlaminar fracture toughness increased by 7% and 54%, respectively. This research highlights the potential of hybrid reinforcement in advancing SHM capabilities for CFRP composites, thus paving the way for safer and more reliable structures.

Inhibiting concentration quenching in Yb3+-Tm3+ upconversion nanoparticles by suppressing back energy transfer Lanthanide-doped upconversion nanoparticles are promising for applications ranging from biosensing, bioimaging to solid-state lasing. However, their brightness remains limited by the concentration quenching effect of lanthanide activator ions, which greatly restricts their utility. Here, we develop a heterogeneous core-shell-shell nanostructure based on hexagonal NaYF<sub>4</sub>, in which Tm<sup>3+</sup> activator and Yb<sup>3+</sup> sensitizer are separated into the core and inner shell, while the outmost shell is used to suppress surface quenching effects. We show that this design can alleviate the activator concentration quenching effect, resulting in optimal Tm<sup>3+</sup> concentration increasing from 1% to 8% at sub-100 W/cm<sup>2</sup> irradiance, compared with the canonical core-only NaYF<sub>4</sub>:Yb<sup>3+</sup>/Tm<sup>3+</sup>. Moreover, under high excitation irradiance (20 MW/cm<sup>2</sup>), the optimal Tm<sup>3+</sup> concentration could be further increased to 50%. Mechanistic investigations reveal that the spatial separation of sensitizer and activator effectively suppresses the back energy transfer from Tm<sup>3+</sup> to Yb<sup>3+</sup>, driving the increase of optimal activator concentration. These findings enhance our understanding of lanthanide concentration quenching effect, unleashing opportunities for developing bright upconverting materials.

Autonomous platform for solution processing of electronic polymers The manipulation of electronic polymers' solid-state properties through processing is crucial in electronics and energy research. Yet, efficiently processing electronic polymer solutions into thin films with specific properties remains a formidable challenge. We introduce Polybot, an artificial intelligence (AI) driven automated material laboratory designed to autonomously explore processing pathways for achieving high-conductivity, low-defect electronic polymers films. Leveraging importance-guided Bayesian optimization, Polybot efficiently navigates a complex 7-dimensional processing space. In particular, the automated workflow and algorithms effectively explore the search space, mitigate biases, employ statistical methods to ensure data repeatability, and concurrently optimize multiple objectives with precision. The experimental campaign yields scale-up fabrication recipes, producing transparent conductive thin films with averaged conductivity exceeding 4500 S/cm. Feature importance analysis and morphological characterizations reveal key design factors. This work signifies a significant step towards transforming the manufacturing of electronic polymers, highlighting the potential of AI-driven automation in material science.

Formation of hydrided Pt-Ce-H sites in efficient, selective oxidation catalysts Single-atom site catalysts can improve the rates and selectivity of many catalytic reactions. We have modified Pt<sub>1</sub>/CeO<sub>2</sub> single sites by combining them with molecular groups and with oxygen vacancies of the support. The new sites include hydrided (Pt<sup>2+</sup>-Ce<sup>3+</sup>H<sup>δ-</sup>) and hydroxylated (Pt<sup>2+</sup>-Ce<sup>3+</sup>OH) sites that exhibit higher reactivity and selectivity to previous single sites for several reactions, including a ninefold increase in the reaction rate for carbon monoxide oxidation and a 2.3-fold improvement of propylene selectivity for oxidative dehydrogenation of propane. The atomic structure and reaction steps of these sites were determined with in situ and ex situ spectroscopy techniques and theoretical methods.

Multifunctional Carbon Foam with Nanoscale Chiral Magnetic Heterostructures for Broadband Microwave Absorption in Low Frequency The construction of carbon nanocoil (CNC)-based chiral-dielectric-magnetic trinity composites is considered as a promising approach to achieve excellent low-frequency microwave absorption. However, it is still challenging to further enhance the low frequency microwave absorption and elucidate the related loss mechanisms. Herein, the chiral CNCs are first synthesized on a three-dimensional (3D) carbon foam and then combined with the FeNi/NiFe<sub>2</sub>O<sub>4</sub> nanoparticles to form a novel chiral-dielectric-magnetic trinity foam. The 3D porous CNC-carbon foam network provides excellent impedance matching and strong conduction loss. The formation of the FeNi-carbon interfaces induces interfacial polarization loss, which is confirmed by the density functional theory calculations. Further permeability analysis and the micromagnetic simulation indicate that the nanoscale chiral magnetic heterostructures achieve magnetic pinning and coupling effects, which enhance the magnetic anisotropy and magnetic loss capability. Owing to the synergistic effect between dielectricity, chirality, and magnetism, the trinity composite foam exhibits excellent microwave absorption performance with an ultrabroad effective absorption bandwidth (EAB) of 14 GHz and a minimum reflection of loss less than - 50 dB. More importantly, the C-band EAB of the foam is extended to 4 GHz, achieving the full C-band coverage. This study provides further guidelines for the microstructure design of the chiral-dielectric-magnetic trinity composites to achieve broadband microwave absorption.

Their high surface area and adjustable pore sizes make them ideal for a range of applications, including CO<sub>2</sub> capture, CH<sub>4</sub> storage, gas separation, catalysis, etc. Traditional methods of material research, which mainly rely on manual experimentation, are not particularly efficient, while with advancements in computer science, high-throughput computational screening methods based on molecular simulation have become crucial in material discovery, yet they face limitations in terms of computational resources and time. Currently, machine learning (ML) has emerged as a transformative tool in many fields, capable of analyzing large data sets, identifying underlying patterns, and predicting material performance efficiently and accurately. This approach, termed "materials genomics", combines high-throughput computational screening with ML to predict and design high-performance materials, significantly speeding up the discovery process compared to traditional methods. This review discusses the functions of ML in the screening, design, and performance prediction of COFs and highlights their applications across various domains like CO<sub>2</sub> capture, CH<sub>4</sub> storage, gas separation, and catalysis, thereby providing new research directions and enhancing the understanding of COF materials and their applications.
