Zinc-ion hybrid super-capacitors are regarded as promising safe energy storage systems,However,the relatively low volumetric energy density has become the main bottlenecks in practical applications of portable electronic devices,In this work,the zinc-ion hybrid super-capacitor with high volumetric energy density and superb cycle stability had been constructed which employing the high-density threedimensional graphene hydrogel as cathode and Zn foil used as anode in 1 mol/L ZnSO4 *** from the abundant ion transport paths and the abundant active sites for graphene hydrogel with high density and porous structure,the zinc-ion hybrid super-capacitor exhibited an extremely high volumetric energy density of 118.42 Wh/L and a superb power density of 24.00 kW/L,as well as an excellent long cycle life(80% retention after 30,000 cycles at 10 A/g),which was superior to the volumetric energy density of the reported zinc-ion hybrid *** device,based on the fast ion adsorption/deso rption on the capacitor-type graphene cathode and reversible Zn^(2+) plating/stripping on the battery-type Zn anode,which will inspire the development of zinc-ion hybrid super-capacitor in miniaturized devices.

Quasi-two-dimensional (quasi-2D) perovskites offer enhanced stability compared to conventional 3D analogs, but their applications in photovoltaics are hindered by low power conversion efficiencies (PCEs). The limited PCEs primarily originate from low short-circuit current density (), caused by insufficient optical absorption, inefficient exciton dissociation and poor charge transport. Here, we find that the PCEs of quasi-2D perovskite solar cells (PSCs) can be significantly enhanced by incorporating gold nanoparticles (Au NPs) into quasi-2D perovskite layers. The optimized device achieves a champion PCE of 22.39%, ranking among the highest reported values for quasi-2D PSCs while retaining intrinsic stability. Our results demonstrate that Au NPs moderately promote light harvesting via plasmonic effects and increased perovskite layer thickness. More significantly, Au NPs substantially reduce exciton binding energy and enhance exciton dissociation probability, thereby facilitating charge separation and primarily driving device PCE improvement.

The recently emerging superconductivity in infinite-layer nickelates with the isostructural and isoelectronic characteristics of cuprates provides a new platform to explore the pairing mechanism of high-temperature superconductors. In this work, we studied the upper critical field (Hc2) of a high-quality La0.8Sr0.2NiO2 thin film with superconducting transition temperature, Tconset=18.8 K, using high magnetic field up to 56 T. A very large Hc2, ∼40 T for H∥c and ∼52 T for H⊥c, was confirmed, which suggests that infinite-layer nickelates also have great application potential. The anisotropy of Hc2 monotonically decreases from ∼10(γ=Hc2ab/Hc2c) near Tc to ∼1.5 at 2 K. Angle dependence of Hc2 confirms the crossover of superconductivity from two-dimensional to three-dimensional as the temperature decreases. We discussed that the interstitial orbital effect causes the weakening of anisotropy. The observed abnormal upturning of Hc2 at low temperatures is found to be a universal behavior independent of film quality and rare-earth elements. Therefore, it should not be the Fulde-Ferrell-Larkin-Ovchinnikov state due to the fact that it is in the dirty limit and insensitive to disorder.

solid superlubricity of diamond-like carbon films: a review

With the origin of life and the advancement of human society, friction has become an integral part of human civilization’s development. Approximately one-third to one-half of the world’s energy consumption is attributed to friction. Lubrication plays a crucial role in reducing friction and wear, enhancing resource efficiency, and promoting a green industry. Achieving superlubricity, where friction approaches zero, is one of the primary research objectives in lubrication science. The evolution of superlubricity has progressed from theoretical to experimental validation, transitioning from atomic-scale superlubricity on perfect crystal planes to various macro-scale applications today. Unlike two-dimensional materials, diamond-like carbon (DLC) films can be deposited onto metal substrates and exhibit high hardness (10–80 GPa), enabling better resistance to local deformation and wear, and reducing material loss. This allows DLC films to maintain performance under high loads. Together with the elastic modulus, hardness determines the deformation behavior of DLC films under load. DLC films with high hardness typically have a high elastic modulus, making them less prone to plastic deformation under normal load and enhancing their load-bearing capacity. These characteristics make DLC films one of the most promising candidates for engineering superlubricity applications. By carefully choosing suitable testing environments, element doping methods, or subjecting carbon films to hydrogen plasma treatment, superlubricity has been successfully achieved across various conditions. This paper comprehensively sums up the current understanding of superlubricity of DLC films. The discussion follows a logical sequence: starting with the superlubricity of hydrogenated DLC films, then moving on to element-doped DLC films, followed by special structure DLC films, and finally exploring the synergy superlubricity of DLC films. The paper concludes with an in-depth analysis of the industrial p

Moiré transition metal dichalcogenide (TMD) systems provide a tunable platform for studying electron-correlation driven quantum phases (1). Such phases have so far been found at rational fillings of the moiré superlattice, and it is believed that lattice commensurability plays a key role in their stability. In this work, we show via magnetotransport measurements on twisted WSe2 that new correlated electronic phases can exist away from commensurability. The first phase is an antiferromagnetic metal that is driven by proximity to the van Hove singularity. The second is a re-entrant magnetic field-driven insulator. This insulator is formed from a small and equal density of electrons and holes with opposite spin projections – an Ising excitonic insulator. © 2024, CC BY.

为了深入理解超薄晶态材料的结构和对称性的独特性,本文在充分考虑超薄晶态材料堆积自由度的情况下,从数学和晶体学角度对介于二维与三维之间的超薄纳米晶体的对称性和X射线衍射进行了探讨.认为超薄纳米晶体的对称性需要用数学层群(layer group)来描述;另外,由于其层堆叠方向上不具有周期性结构,超薄纳米晶体可能产生特异衍射特征.为了验证这一观点,研究了三类在层堆叠方向不具有周期性的典型超薄纳米晶体的X射线衍射,从实验上观察到了超薄纳米晶体与其体相三维晶体粉末X射线衍射的不同;针对基于三维晶体的X射线衍射模拟软件不再适用于超薄纳米晶体的情况,发展了超薄纳米晶体的全结构X射线衍射分析方法,很好地模拟了超薄纳米晶粉末X射线衍射图.该研究对超薄纳米晶态材料的结构及对称性提出了新见解,将有益于推动相关材料的构效关系研究和新功能开发.
