Atomically-thin materials continue to captivate researchers due to their extraordinary physical properties that often surpass those of their bulk forms. Among them, two-dimensional (2D) silicates hold particular promise, yet their nonlinear optical characteristics remain largely underexplored. This study provides an in-depth analysis of the size-dependent nonlinear optical response and optical limiting characteristics of 2D rhodonite nanoflakes, a non-layered silicate mineral, under femtosecond laser excitation. A pronounced enhancement in two-photon absorption is observed as the material transitions from large flakes (∼40 nm thickness) to few-layer structures (∼2.5 nm thickness), with the two-photon absorption coefficient increasing from the 103 to 104 cm GW−1 range, highlighting the influence of dimensional tuning. Few-layer rhodonite exhibits an ultralow optical limiting threshold of 0.38 mJ cm−2, outperforming many benchmark 2D materials, including graphene, TMDCs and MXenes. Density functional theory analysis indicates that the enhanced two-photon absorption in 2D rhodonite arises from the contributions of Fe orbitals originating from electronic states near the Fermi level. In addition, the increased probability of two-photon absorption can also be attributed to transitions between orbitals of similar character with strong contributions, which occur as a result of the hybridization between Si and O p orbitals. These findings position 2D rhodonite as a highly promising candidate for next-generation photonic technologies, including optical switching, 3D microfabrication, and quantum information processing.
原子薄材料由于其非凡的物理特性而继续吸引着研究人员，这些特性通常超过它们的体积形式。其中，二维（2D）硅酸盐具有特别的前景，但其非线性光学特性在很大程度上仍未得到充分研究。本研究深入分析了飞秒激光激发下非层状硅酸盐矿物二维菱铁矿纳米片的尺寸相关非线性光学响应和光学极限特性。当材料从大薄片（~ 40 nm厚度）转变为少层结构（~ 2.5 nm厚度）时，双光子吸收显著增强，双光子吸收系数从103到104 cm GW−1范围内增加，突出了尺寸调谐的影响。少层菱铁矿具有0.38 mJ cm−2的超低光限阈值，优于许多基准2D材料，包括石墨烯、TMDCs和MXenes。密度泛函理论分析表明，二维菱铁矿的双光子吸收增强是由费米能级附近电子态的铁轨道的贡献引起的。此外，双光子吸收概率的增加也可以归因于Si和O p轨道之间的杂化导致的具有相似特征且贡献很大的轨道之间的跃迁。这些发现将二维菱铁矿定位为下一代光子技术的极有前途的候选者，包括光开关、3D微加工和量子信息处理。

Surface-area normalization is essential for quantitative comparison in electrochemistry, yet ambiguity in what area represents hampers interpretation and reproducibility. We distinguish the real surface area, a geometric measure of surface roughness and structure, from the electrochemically active surface area, defined as the condition-dependent subset of surface sites participating in a specific faradaic reaction. We clarify how double-layer capacitance and adsorption-limited charge-transfer reactions probe different regions of the electrode surface and how their interpretation and reference values determine whether the result corresponds to an apparent area, the real surface area, or the electrochemically active surface area. We further show that commonly used reference values vary strongly with electrode structure, electrolyte composition, and measurement protocol. To address this, we introduce a formalism based on domain-specific linear combinations of surface contributions that enables structurally consistent area estimates. Finally, we propose normalizing current by active-site count as a direct and reproducible measure of intrinsic activity.

The application of more blood proteins into health risk prediction and disease diagnostics has long garnered significant interest. However, comprehensive profiling of proteins in blood samples (plasma or serum), particularly low-abundance proteins, remains technically challenging due to the masking effect imposed by high-abundance proteins and the extraordinarily wide dynamic range of protein abundances. Herein, we developed an efficient strategy that leveraged the protein corona formed on surfactant-modified magnetic nanoparticles for the selective enrichment of low-abundance plasma proteins. Coupled with liquid-chromatography tandem mass spectrometry (LC-MS/MS) analysis, this strategy allowed for the detection of over 3500 plasma proteins in a single run, which was approximately three times and five times more than the number of proteins detected by the antibody-dependent depletion method and the direct digestion method, respectively. The application of our method to an acute myocardial infarction (AMI) cohort and corresponding healthy control group resulted in the identification of 5000 more plasma proteins and the discovery of seven potential AMI diagnostic biomarkers, which showed superior accuracy in diagnosis compared to conventionally used cardiac troponins. The magnetic nanoparticles (MNPs) and surfactants are commercially accessible and cost-effective, and moreover, the modification protocol is simple. These features ensure the ready adoption of our method by other laboratories, even those lacking specialized nanotechnology expertise. Additionally, the magnetic properties of MNPs can further facilitate the smooth integration with automated sample processing systems, thereby expediting large-scale clinical studies.

Thermal/hydrogen-induced disproportionation is one of the most fatal obstacles for practical Zr2Fe-based hydrogen isotope storage alloys. Here, an interfacial transport inhibition effect at the disproportionation interface is revealed, in which theoretical screening from a product-destabilization perspective identifies minor Nb substitution as an effective route to developing a disproportionation-resistant Zr1.9Nb0.1Fe0.7Ni0.3 alloy. This composition preserves an ultralow equilibrium hydrogen pressure and accelerated hydrogen absorption kinetics, while simultaneously delivering markedly enhanced resistance to disproportionation and outstanding cycling stability under harsh conditions. By integrating experimental results with thermodynamic and kinetic analyses, this work directs modification studies toward the viewpoint of interfacial transport kinetics for disproportionation. Combined density functional theory analyses and Ab initio molecular dynamics simulations systematically reveal that dispersed substitutional Nb atoms act as interfacial pinning centers at the hydride/disproportionation interfaces, effectively inhibiting detrimental interfacial phase transformation, closely related to weakened interfacial bonding strength, charge transfer, and orbital hybridization. Consequently, disproportionation-related atomic rearrangement as well as the nucleation and growth of ZrH2 are kinetically retarded. For the first time, these findings demonstrated that targeted interfacial kinetic engineering constitutes an effective strategy for suppressing disproportionation in Zr2Fe-based hydrogen storage systems.

This work focused on the synthesis of B-site-engineered medium-entropy perovskite oxides (MEPOs) with a general equimolar composition of La(Ti0.25Mn0.25Fe0.25Co0.25)O3 (LTMFC), along with non-equimolar compositions in the B-site to explore the effect of cation disorder on structural and electrochemical performance. X-ray diffraction studies confirm the formation of a single-phase orthorhombic perovskite structure with the pbnm space group for both equimolar and non-equimolar compositions. The non-equimolar La(Ti0.15Mn0.15Fe0.35Co0.35)O3 (TM-0.15) exhibits lattice expansion induced by oxygen vacancies, accompanied by partial reduction of Ti4+ to Ti3+, as verified by X-ray photoelectron spectroscopy. Compared with the equimolar LTMFC, non-equimolar TM-0.15 exhibits higher conductivity and faster ion diffusion, resulting in a specific capacitance of 526 F g−1 at 1 A g−1, exceeding that of the equimolar LTMFC (486 F g−1) under identical conditions. Binder-free electrophoretic deposition enables uniform coating over Ni foam with excellent interfacial contact. TM-0.15 was incorporated into poly(vinylidene fluoride) (PVDF) to fabricate a piezoelectric nanogenerator (PENG) that charges the charge-storing devices. 5 wt% of TM-0.15 in PVDF exhibits a higher piezoelectric output voltage of 5 V at 1.5 kgf and is capable of charging a 2.2 µF capacitor to 1.45 V within 25 s. This study suggests that non-equimolar B-site engineering in MEPOs offers a viable strategy to outperform equimolar counterparts, enabling synergistic energy storage and harvesting.
本文主要研究了以等摩尔成分La(Ti0.25Mn0.25Fe0.25Co0.25)O3 （LTMFC）和非等摩尔成分组成的b位工程中熵钙钛矿氧化物（MEPOs）的合成，探讨了阳离子无序性对结构和电化学性能的影响。x射线衍射研究证实了等摩尔和非等摩尔成分形成了具有pnm空间基的单相正交钙钛矿结构。x射线光电子能谱证实，非等摩尔La(Ti0.15Mn0.15Fe0.35Co0.35)O3 （TM-0.15）表现出由氧空位引起的晶格膨胀，Ti4+部分还原为Ti3+。与等摩尔LTMFC相比，非等摩尔TM-0.15具有更高的电导率和更快的离子扩散，在1 a g−1时的比电容为526 F g−1，超过等摩尔LTMFC在相同条件下的比电容（486 F g−1）。无粘结剂电泳沉积使均匀涂层镍泡沫具有良好的界面接触。将TM-0.15掺入聚偏二氟乙烯（PVDF）中，制造压电纳米发电机（PENG），为电荷存储装置充电。在PVDF中加入5 wt%的TM-0.15，在1.5 kgf时，压电输出电压高达5 V，能够在25秒内将2.2µF的电容器充电至1.45 V。该研究表明，MEPOs中的非等摩尔b位点工程提供了一种可行的策略，可以超越等摩尔的b位点，实现协同能量存储和收集。

Amid the accelerated expansion of the green hydrogen industry, seawater electrolysis is emerging as a pivotal route for large-scale hydrogen production, owing to its abundant feedstock and cost advantages. Nevertheless, the competing anode corrosion reaction and the intrinsically sluggish OER kinetics engendered by high chloride concentrations impose decisive constraints on the industrial deployment of conventional catalysts. Transition Metal Phosphides (TMPs), characterized by metallic conductivity, tunable electronic structures, and high intrinsic activity, have become the catalytic system of choice for overcoming these limitations. Under electrochemical conditions, TMP surfaces undergo dynamic reconstruction to enhance performance through a synergistic mechanism: electron redistribution effect, lattice oxygen activation, and an in situ corrosion barrier that electrostatically repels Cl−. To bridge the gap between laboratory validation and industrial realization, this review systematically explores optimization strategies encompassing compositional design, structural innovation, and dynamic interface regulation. In real seawater and at industrially relevant current densities exceeding 500 mA cm−2, TMP electrodes demonstrate substantial potential; nonetheless, large-scale deployment still confronts formidable challenges. Future efforts must integrate operando XAFS/Raman characterization with Machine Learning driven data analytics to unravel atomic-scale reconstruction pathways and resolve engineering hurdles associated with high current density, prolonged durability, and complex environmental adaptability, thereby propelling TMP-based seawater electrolysis toward practical implementation in gigawatt-level green hydrogen plants.
随着绿色氢产业的加速发展，海水电解因其原料丰富、成本优势而成为大规模制氢的关键途径。然而，高氯化物浓度引起的竞争性阳极腐蚀反应和内在缓慢的OER动力学对传统催化剂的工业部署造成了决定性的限制。过渡金属磷化物（TMPs）具有金属导电性、可调谐电子结构和高固有活性的特点，已成为克服这些限制的首选催化体系。在电化学条件下，TMP表面通过电子再分配效应、晶格氧活化和静电排斥Cl−的原位腐蚀屏障等协同机制进行动态重构以提高性能。为了弥合实验室验证和工业实现之间的差距，本文系统地探讨了包括成分设计、结构创新和动态界面调节在内的优化策略。在实际海水和工业相关电流密度超过500 mA cm - 2时，TMP电极显示出巨大的潜力；尽管如此，大规模部署仍然面临着艰巨的挑战。未来的努力必须将操作系统XAFS/拉曼表征与机器学习驱动的数据分析相结合，以揭示原子尺度的重建途径，解决与高电流密度、长寿命和复杂环境适应性相关的工程障碍，从而推动基于tmp的海水电解在千兆瓦级绿色氢电厂的实际应用。
