目前,广泛用于正型有机太阳能电池的空穴提取层(HEL)材料是PEDOT:PSS.然而, PEDOT:PSS的酸性会腐蚀氧化铟锡(ITO)电极,降低器件的稳定性.本文采用中心氟化策略,设计合成了一种双膦酸型自组装单分子层(SAM)材料3BPIC-cF.与PEDOT:PSS相比, 3BPIC-cF修饰的ITO基底具有更高的光透过率和更好的界面相容性.氟原子的引入使得3BPIC-cF具有更大的偶极矩和更深的最高占据轨道能级,导致ITO/3BPIC-cF基底具有比ITO/PEDOT:PSS基底更大的功函数.这些优势有利于空穴的提取,降低界面阻抗并抑制界面处的非辐射复合.使用3BPIC-cF作为HEL的有机太阳能电池实现了19.34%的光伏效率,优于PEDOT:PSS器件(PCE=18.64%).此外,基于3BPIC-cF的光伏器件具有比基于PEDOT:PSS的器件更高的稳定性.本研究为面向高效有机太阳能电池中SAM分子的设计与合成提供了有价值的指导.

Chiral multifold fermions in solids exhibit unique band structures and topological properties, making them ideal for exploring fundamental physical phenomena related to nontrivial topology, chirality, and symmetry breaking. However, the challenge of obtaining clean, flat surfaces through cleavage has hindered the investigation of their unique electronic states. In this study, we utilize high-resolution angle-resolved photoemission spectroscopy and density functional theory calculations to investigate the low-energy electronic structure of the cleavable single-crystal PdSbSe. Our combined experimental and theoretical analysis reveals the presence of multifold-degenerate fermions within this chiral crystal. We also observe multiple chiral Fermi arc surface states and spin-splitting behavior in the associated bulk bands. These findings provide unique insights into chiral, multifold fermionic states in easily cleavable crystals and offer a robust platform for further research into their unique electronic properties and potential applications in novel electronic devices.

Graphene and related materials are emerging revolutionary materials due to fascinating stimuli-responsive physiochemical properties having widespread applications in developing advanced nano-systems for detection, diagnostics, and therapeutics in biomedical fields. Various materials like metal nanoparticles, polymers, dyes, drugs, and proteins could be combined yielding graphene-based composite materials (GBCMs) to synergistically fulfill different biomedical requirements. The 2D conjugated structure, easy surface functionalization via covalent or van der Waal interactions, and combination with different components for versatile functionalities altogether contribute to the development of GBCM for healthcare applications. This review specifically focuses on GBCMs and discusses specific material properties relevant to their material applications in healthcare. Furthermore, the synthesis, toxicity, and biocompatibility of these GBCMs, and their interactions with biological materials are thoroughly discussed. Importantly, the recent cutting-edge applications in the field of healthcare, including its role in the development of antibacterial, anti-viral, and photothermal therapies, wound healing, drug delivery, neurodegenerative disease therapy, and biosensing based on GBCMs are well-updated. Additionally, the applications of GBCMs in point-of-care devices, wearable electronics, and tissue engineering are well summarized. We hope this review opens up more possibilities to design more innovative healthcare materials derived from graphene. © 2025 The Authors

Influence of alloy composition on the overall performance of gas-atomized Fe–Si powder cores

Optimizing alloy composition has emerged as an effective technique to further enhance the overall performance of traditional Fe–Si soft magnetic powder cores. Influences of alloy composition on the overall performance of Fe–Si powders and powder cores with similar particle size distributions were investigated. As the Si content increased from 4 to 6 wt%, the hardness of FeSi powders with good flowability increased. This, along with the introduction of light element, leads to a decrease in density and thus an increase in resistivity for powder cores. After passivation, good insulation quality ensured a similar stable effective permeability of about 60 in the frequency range of 100–1000 kHz for all Fe–Si powder cores. Reduced saturation magnetization of Fe–Si alloy resulted in deterioration of DC bias performance of powder core with increasing Si content. Due to the lowest hysteresis loss, which was dominant in the test frequency range below 150 kHz, Fe–Si5 powder core was found to have the lowest core loss (2496.5 mW/cm3 at 150 kHz and 100 mT). This favors the smallest temperature rise of + 4.7 °C of Fe–Si5 powder core when applied as an inductor. This work gained deeper insights into the relationship between alloy compositions and the mechanical, electrical, and magnetic properties of Fe–Si powder cores. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2025.

Traditional ceramic materials are prone to crushing due to structural collapse at high temperatures. Current efforts are focused on developing flexible and elastic ceramic materials with high thermal stability to address practical needs in the field of high-temperature thermal insulation, but this remains a significant challenge. In this work, elastic and compressible barium aluminosilicate (BAS) nanofibrous sponges are fabricated through gelation electrospinning and calcination processes. The resulting BAS nanofibrous sponges demonstrate excellent elasticity and compressibility across a temperature range of −196 to 1400 °C and can withstand 1000 compression cycles without structural collapse. Furthermore, they exhibit low thermal conductivity (0.0239 W m-1 K-1), low bulk density (4.42 mg cm-3), and high working temperature. In this sense, our study highlights the great potential of BAS nanofibrous sponges as thermal protective materials in extreme operating environments. © 2025 American Chemical Society.

Fluoroalkane modified silica aerogels with excellent strength and self-cleaning property

Journal of Non-Crystalline Solids 2025年 662卷

Silica aerogel, regarded as one of the lightest solid materials with porous structures, shows properties such as low thermal conductivity, high porosity, and extensive surface area, making it highly suitable for application in pipeline thermal insulation, aerospace engineering, oil-water separation, and various other fields. However, due to the neck effect in the pearl-like network formed by the direct and random interconnection between silica nanoparticles, the mechanical property is poor. Although the mechanical property is enhanced by modifying silica aerogels with inorganic and organic compounds, the thermal insulation is usually sacrificed with enhancing of mechanical property. In this study, low surface energy fluoroalkane modified silica aerogels (SAF) are prepared to enhance the compressive mechanical and superhydrophobic properties. In order to balance the mechanical property and the thermal insulation property, SAF with different contents of fluoroalkanes are studied in detail. The compressive strength of SAF with 10 % molar ratio of fluoroalkanes is greatly enhanced while the thermal conductivity keeps the same as unmodified silica aerogel to balance the mechanical and thermal insulation properties. Study on the structure and property of SAF aerogels shows that the mechanical property is enhanced at proper molar content of fluoroalkanes, which probably thickens the necks between silica particles and lower the crosslinking density. The SAF aerogels shows excellent insulation against thermal and cold conditions. Furthermore, the surfaces of SAF aerogels are superhydrophobic by introducing low surface energy fluoroalkanes, and show self-cleaning property, facilitating the application of silica aerogels. © 2025 Elsevier B.V.

With the advancement of hypersonic vehicles, extreme high temperature environments have imposed increasingly stringent requirements on the performance of thermal protection systems. Consequently, the development of high-performance thermal protection materials capable of withstanding extreme conditions has become a primary focus of current research. Ultra-high temperature ceramics (UHTCs) and their composites, known for their excellent oxidation resistance and ablation performance, are regarded as highly promising non-ablative thermal protection materials. This paper provides a systematic review of recent research progress on UHTC composites in several key areas, including innovations and optimizations in fabrication processes, exploration of toughening strategies and mechanisms, in-depth studies on oxidation and ablation resistance mechanisms, and the development and potential applications of high-entropy ceramics. Furthermore, the paper discusses the practical application prospects of UHTCs and their composites in extreme environments, analyzes the current technical challenges, and proposes future research directions and priorities.
