Two-dimensional (2D) materials have immense potential to advance flexible electronics, yet they are limited by low fracture toughness. This study addresses the intrinsic toughening of monolayer amorphous carbon (MAC), a 2D nanocomposite, to overcome this challenge. By incorporating both amorphous and nanocrystalline phases, MAC significantly enhances energy absorption during fracture propagation, as evidenced by crack blunting, deflecting, and bridging. Using in situ tensile tests under a scanning electron microscope, our results indicate an 8-fold increase in the energy release rate compared to monolayer graphene, along with improved fracture strain and crack stability. Molecular dynamics simulations demonstrate the impact of phase composition on fracture energy. Our results present a scalable toughening strategy for 2D materials, potentially broadening their applications in fields requiring robust fracture resistance.

Pt and its derivatives, with their high reactivity and stability, are ideal electrocatalysts for the hydrogen evolution reaction (HER). Despite being the industrial standard in HERs, high current densities remain prohibitive due to the increased risk of leaching. Here, we report a practical and scalable strategy to prepare extremely stable Pt-based electrodes employing porous aromatic framework (PAF-260, -261, and -264) membranes instead of commercial Nafion binders to render fully exposed Pt nanocatalysts as well as faster electron and mass transfer. All electrodes exhibit excellent HER performances, continuously operating for more than 1,000 h at ampere-level current densities without losing activity. The precise placement of Pt-anchoring sulfur functionalities throughout the porous framework enables the homogeneous distribution of electrocatalysts that deliver continuous production of hydrogen, even in highly alkaline environments. The design principles from this study could unravel robust electrolyzers that could accelerate the transition to renewable fuels.
铂及其衍生物具有高反应活性和稳定性，是氢进化反应（HER）的理想电催化剂。尽管已成为氢进化反应的工业标准，但由于沥滤风险的增加，高电流密度仍然令人望而却步。在此，我们报告了一种实用且可扩展的策略，即采用多孔芳香族框架（PAF-260、-261 和 -264）膜代替商用 Nafion 粘合剂来制备极其稳定的铂基电极，从而使铂纳米催化剂充分暴露，并加快电子和质量传输。所有电极都表现出卓越的 HER 性能，可在安培级电流密度下连续工作 1000 小时以上而不会失去活性。在整个多孔框架中精确放置铂锚定硫官能团，可实现电催化剂的均匀分布，即使在高碱性环境中也能持续产生氢气。这项研究的设计原则可以开发出坚固耐用的电解器，加快向可再生燃料的过渡。

Crystal symmetry plays a fundamental role in emergent properties and behavior. Subject to external excitations, such as a strain gradient, changes in symmetry may lead to new properties. Recent research demonstrates that bending perovskite-based photovoltaic cells can enhance their efficiency by approximately 15%, suggesting a novel pathway for increasing performance.

This study redefines Prussian blue analogs (PBAs), transforming them into Prussene—a two-dimensional (2D) layered nanomaterial—via laser-shock-induced 2D phase transition synthesis (LSPT2D). This scalable nanomanufacturing technique harnesses high-temperature/pressure plasmas to drive phase transitions, converting PBA nanocubes into N-doped carbon nanosheets embedded with ultrafine magnetic nanoalloys. Unlike conventional exfoliation method, LSPT2D enables chemical phase engineering, preserving structural integrity while imparting exceptional properties. Prussene exhibits a high saturation magnetization (108.3 emu/g) and enhanced conductivity due to its conductive carbon matrix. Demonstrating transformative electromagnetic wave absorption, it achieves a reflection loss of −51.7 dB and a 5.87 GHz effective bandwidth across GHz–THz frequencies, surpassing state-of-the-art absorbers. These attributes position Prussene as a breakthrough for stealth technologies and ultrahigh-frequency communications. This work establishes a scalable paradigm for synthesizing chemically modified 2D materials, unlocking applications in catalysis, energy storage, and multifunctional nanoelectronics. Prussene’s innovation lies in its synthesis-process-property triad, heralding a new era in high-performance nanomaterials.

Increased intestinal permeability, gut microecology dysbiosis, and the development of inflammatory bowel disease (IBD) are closely linked. Defective Paneth cell (PC) differentiation and disrupted goblet cell (GC) mucus exacerbate intestinal inflammation, driving IBD progression. In this context, we investigated the therapeutic effects of tungsten-encapsulated zinc nanoparticles (W@ZnNPs) in murine models of IBD. W@ZnNPs, with their high gastric stability and minimal side effects, have been found to enhance the mucosal barrier by improving Paneth and goblet cell functions, thus mitigating gut microbiota dysbiosis-induced inflammation. Orally delivered, W@ZnNPs outperformed mesalamine and other nanoadjuvants in ameliorating colitis, mainly through a dual mechanism of tungsten-mediated editing of Enterobacteriaceae and zinc-mediated modulation of intestinal cells. Most importantly, W@ZnNPs hold the potential to restore host-microbe interactions, making them a promising nanotherapeutic for IBD treatment.

Metal halide perovskites have emerged as promising materials for diverse optoelectronic devices due to their superior optical properties. However, their instability in moisture hinders practical use, highlighting the need for an atomic-scale understanding of their degradation mechanism. Here, we uncover water-induced degradation pathways of perovskite nanocrystals using in situ liquid-phase transmission electron microscopy, revealing a distinctive dissolution process driven by ion solvation. The dissolution rates vary according to crystallographic direction, influenced by the surface polarity of different crystal facets, leading to a shape transformation from nanocubes to nanospheres. These observations are further supported by in situ X-ray scattering analysis. Notably, surface passivation of perovskite nanocrystals with halide ion pair ligands provides effective edge passivation, alters the degradation trajectories by preserving their cubic shape during the initial stages, and significantly reduces the overall degradation rate. This study offers critical insights into the water-induced degradation mechanisms of perovskite nanocrystals, potentially guiding strategies to enhance their stability.

The solar-to-chemical conversion (SCC) efficiency of hydrogen peroxide (H2O2) photosynthesis is governed by the O2 adsorption model and energy level, which are experimentally challenging to be tuned. Herein, we report a new strategy for tuning of the O2 adsorption and electron potential energy level of covalent organic frameworks (COFs) using halogen atom (F, Cl, Br, and I) as a regulatory reagent, and demonstrate that I-COFs exhibit the maximum thermodynamic driving force for 2e– oxygen reduction reaction (ORR). The introduction of I atom inhibits the O–O bond breakage for enhancing the selectivity of 2e– ORR from 56.5% to 87.0%, thus promoting the continuous natural sunlight-driven photosynthesis of H2O2 directly from water and air, showing a high SCC efficiency of 1.88% and the operational stability of over 200 h. Meanwhile, I-COFs also show 100% antibacterial performance and efficient wound healing ability, which is significantly better than that of H-COFs with symmetric electron distribution.

Radiative cooling coating (RCC) provides a sustainable pathway for thermal management. However, the spectrally engineered RCC’s thermal regulation behavior relies heavily on clear weather, limiting the development of its adaptive thermal management performance and high cooling power. Inspired by the skin’s thermo-regulation, we report a bionic skin meta-gel coating (BSMC) with an adaptive spectrum and moisture modulation capability through hierarchical structure design and localized molecular confinement engineering. Autonomous thermal regulation and high cooling power are attained for the BSMC. Compared to conventional RCC, the BSMC achieves superior cooling performance (a reduction of 4°C) at high temperatures. Conversely, the BSMC can heat a space via photo-thermal effect at low temperatures. Moreover, the BSMC addresses heat accumulation in thermal camouflage nets. According to calculations, the BSMC improves cooling power by 233 W/m2 and significantly decreases global CO2 emissions by 1.9 billion tons/year. The BSMC solves the bottleneck of RCCs and promotes global low-carbon development.

The development of particulate electrochemiluminescence (ECL) emitter with high efficiency is challenging due to either the low electrochemical reaction efficiency for nanoparticles with larger sizes or the low quantum efficiency of molecular luminophores in aggregated forms. While the synthesis of aggregation-induced electrochemiluminescence (AI-ECL) luminophores with high quantum efficiency requires complicated procedures, a supramolecular strategy is proposed for constructing multicomponent nanoaggregates with co-emissive ECL. Aggregation-induced emission (AIE) active tetraphenylethylene (TPE) was used as a molecular matrix to disperse the aggregation-caused quenching (ACQ) luminophores with high quantum efficiency, boron dipyrromethene (BDP), and rhodamine B (RhB). Co-emissions of both molecular matrix and doped luminophores were achieved. The synergistic effects of the supramolecular interactions for enhancement of emission efficiency were confirmed by spectral measurement and molecular dynamic simulation. Small nanoaggregates with higher ECL efficiency were prepared on microfluidic chips and were used as nanolabels for sensitive ECL immunoassays.
