As an emerging electrochemically active material, two-dimensional pyrite (2D-FeS2) with monolayer thickness, short ion diffusion paths, and a high specific surface area. Here, based on theoretical calculations, we predicted the possibility of 2D-FeS2 monolayer as a cathode material for Li-S batteries from three aspects: thermodynamics, electric, and electrochemical properties. It was found that the small exfoliation energy and interlayer binding energy made the 2D-FeS2 monolayer easier to form two-dimensional nano-layered structures. The DOS results show that it has higher conductivity, which effectively improves the mobility of Li+ and electrons. Furthermore, the dynamics simulation results indicated that it has good thermal stability. The nanolayers structure can enhance the anchoring effect of polysulfides and reduce the shuttle effect. The theoretical specific capacity of the 2D-FeS2 monolayer is as large as 446.96 mAh/g-1 and the lower Li+ diffusion barrier is 0.19 eV. The study suggested that 2D-FeS2 monolayer is a promising cathode material for Li-S batteries. Additionally, this work also deepens our understanding of 2D materials at the nanoscale. © 2023, The Authors. All rights reserved.

The increasingly serious problem of electromagnetic radiation pollution has put forward higher requirements for electromagnetic interference (EMI) shielding films to meet the special application such as optical windows, requiring high light transmittance while achieving excellent EMI shielding performance, but it is still a huge challenge. In this study, a symmetrical multilayer structure optimization strategy is employed to prepare transparent broadband EMI shielding films, while achieving high light transmittance and EMI shielding performance. The PC/ITO/Ag/ITO (IAI) film with single transparent conductive oxides (TCO) /metal layer/TCO (TMT) structure exhibits an efficient EMI shielding effectiveness (EMI SE) of 36.5 dB while achieving a light transmittance of 87.5 % at 550 nm. Additionally, superior interface adhesion (5B) enhances the bending resistance and environmental stability of IAI film, and excellent electrical conductivity gives it outstanding Joule heating performance. Furthermore, by designing a symmetrical TMT structure, the double-sided IAI (DIAI) film achieves an even better EMI SE of 67.5 dB within the wide band range (8.2–26.5 GHz), while maintaining an impressive light transmittance of 85.7 % (550 nm). The design of this symmetrical multilayer structure presents a promising approach for developing high-performance transparent EMI shielding films. © 2025 Elsevier B.V.

可被蓝光激发的高热稳定性红色荧光粉是制作高性能白光二极管(WLED)的关键材料.研究发现,Ce^(3+)掺杂的SrLaScO_(4)(SLO:Ce^(3+))荧光粉在440 nm激发下呈现峰值为640 nm的反常宽带红光发射.光谱学和结构分析证实Ce^(3+)离子在SLO中进入[LaO_(8)]多面体,产生强的晶体场劈裂和较大的Stokes位移,实现了比Eu^(2+)更低能量的红光发射.我们还设计并揭示了一种电荷转移相互作用的策略:在Sc^(3+)位置引入电负性较大的Ga^(3+),Ga^(3+)可以吸引更多邻位配合基团的电荷,以减少导带底部的电子占用而扩大带隙.Sc/Ga取代有效地抑制了热激活电离过程,使SrLa(Sc,Ga)O_(4):Ce^(3+)的热稳定性获得了显著提升,即在150℃的发光强度比(相对于20℃)从15%提升至31%.本研究为发现具有良好热稳定性的新型Ce^(3+)掺杂红色荧光粉提供了有效的设计原则.

With the development of artificial intelligence and human-machine interaction technology, achieving all-nanofiber self-powered electronic skin (e-skin) with excellent sensing performance is still a challenge. In this work, polyvinylidene fluoride/polydimethylsiloxane (PVDF/PDMS) nanofiber membranes (PVPD-NFM) were prepared by optimizing the electrospinning humidity parameters. It is determined that when the humidity is 60 %, the roughness of the PVPD-NFM is 7.562 μm, and the content of β-phase is 64 %. After that, the content of PDMS was optimized. Compared with pure PVDF, when the content of PDMS was 42 wt%, the charge density increased from 1.6 μC/m² to 13.7 μC/m², which increased by 8.6 times, respectively. Furthermore, PVPD-NFM also possesses excellent breathability, hydrophobicity, and self-cleaning properties. Finally, the PVPD-NFM was fabricated into e-skin to detect muscle activity in fitness, indicating a promising application prospect in preventing sports injury. © 2025 Elsevier Ltd

Energetic metal–organic frameworks (EMOFs) and EMOF-derived materials are currently a hot spot to replace precious-metal electrocatalysts. Here, the reasonable strategy and synthesis of an inventive class of alloy@C materials from EMOFs via one-step pyrolysis is reported as the first example. The freshly progressive NiCo@C with a individual hierarchical structure, being composed of uniformly distributive metal alloy nanoparticles (MANPs) decorated by N-doped porous hollow carbon nanotubes (HCNTs), displays extraordinary bifunctional catalytic activities for oxygen reduction and oxygen evolution reactions (ORR and OER) than that of commercial precious-metal catalysts. Experimental characterizations and theoretical calculations reveal the vital role of Ni-Co alloy doping in adjusting both performances. Moreover, as an air electrode in Zn–air batteries, NiCo@C demonstrates a large peak power density of 170 mW cm−2 and superior long-term stability over 600 cycles. In consideration of the expansive category of EMOFs and the governable fixation of single/multiple metal particles, this strategy gives evidence of a capacious scientific range. © 2022, The Authors.

Based on the new conception of lattice low-shear stress induced by zero-dimensional point defects, the Al2O3 composite ceramics doped by TiO2 with good high-temperature tribological properties are prepared. According to the results, temperature could control the continuity of the resintering friction layer and the activation of the plastic deformation ability of ceramics. The lattice oxygen in TiO2 leaves the original lattice occupation due to thermal and frictional coupling action, and breaks away from the worn surface, which significantly increases the vacancy concentration level. Aforesaid structural defects are considered to be a crucial reason for the reduction of shear force. This vacancy quantitative change strategy of temperature-sensibility is expected to become a controllable method for providing lubrication during high-temperature. © 2024, The Authors.
