The heterointerface engineering, as a potent approach for modulating the properties of electromagnetic functional materials, can efficiently improve electromagnetic wave absorption (EWA) performance. However, the correlation between heterointerfaces and EMA properties remains unclear. Here, a facile heterointerfaces engineering was proposed to synthesize petal-like lamellar Ni/MnO@C porous nanocomposites, which were derived from the pyrolysis of bimetallic Ni-Mn metal-organic frameworks. This heterointerfaces engineering employed precise Ni/Mn ratio adjustment and thermal regulation to fabricate nanocomposites with desired multiphase and nano-micro heterointerfaces. The heterointerfaces framework integrated with ternary Ni/MnO/carbon components has demonstrated exceptional ferromagnetic and dielectric synergistic characteristics, which contributing to interfacial polarization, electron transport, and magnetic coupling. The dielectric polarization was primarily ascribed to the abundance of heterointerfaces, with multi-phase hybridization playing a predominant role in the interfacial polarization. As expected, excellent EWA performances were characterized by a thin thickness of 1.8 mm, a high-efficiency reflection loss of -60.1 dB, and a broad absorption bandwidth of 5.0 GHz. In addition, the porous heterointerface architecture endowed nanocomposites with favorable flame-retardancy and infrared shielding versatility. Therefore, this study demonstrated the distinctive advantages of the heterointerface engineering in customizing the design of MOFs derivatives, providing a fundamental guide for the development of high-performance functional EMA materials. © 2024, The Authors.

Stable, nonprecious catalysts are vital for large-scale alkaline water electrolysis. Here, we report a grafted superstructure, MOF@POM, formed by self-assembling a metal-organic framework (MOF) with polyoxometalate (POM). In situ electrochemical transformation converts MOF into active metal (oxy)hydroxides to produce a catalyst with a low overpotential of 178 millivolts at 10 milliamperes per square centimeter in alkaline electrolyte. An anion exchange membrane water electrolyzer incorporating this catalyst achieves 3 amperes per square centimeter at 1.78 volts at 80°C and stable operation at 2 amperes per square centimeter for 5140 hours at room temperature. In situ electrochemical spectroscopy and theoretical studies reveal that the synergistic interactions between metal atoms create a fast electron-transfer channel from catalytic iron and cobalt sites, nickel, and tungsten in the polyoxometalate to the electrode, stabilizing the metal sites and preventing dissolution.

Privacy-preserving image generation is particularly crucial in fields like healthcare, where data are both sensitive and limited. However, effective privacy preservation often compromises the visual quality and utility of the generated images due to privacy budget constraints. To address this issue, in this paper, We propose a novel network architecture, IRSEnet, which combines multi-scale feature extraction technology and residual channel attention mechanisms, aiming to enhance the visual quality of generated images and improve the performance of downstream classification tasks under differential privacy. The differential privacy mechanism ensures the security of sensitive data during training, while the multi-scale feature extraction module enhances feature extraction capabilities through parallel convolutional layers at multiple scales. Additionally, the channel attention module dynamically adjusts channel weights to focus on the most discriminative features. Experimental results demonstrate that this model significantly improves the utility of generated images and the accuracy of downstream classification tasks while preserving privacy. Future work will explore the application of this approach on larger datasets and across more diverse tasks.

The combination of CO2 fixation and small organic molecule oxidation offers a promising solution to increasing severe environmental issues and energy crises. Here, low-coordinated NiN3 sites were anchored onto nitrogen-doped ordered mesoporous carbon (Ni-SAs/NOMC), which is capable of efficiently catalyzing the coupled methanol oxidation reaction and CO2 reduction reaction (MOR||CO2RR), thereby reducing the energy required for CO2 conversion and enhancing the economic value of the CO2 electrolytic system. In the membrane electrode assembly electrolyzer-based MOR||CO2RR, Ni-SAs/NOMC achieved Faradaic efficiencies (FEs) of 95.4% for formate at the anode and 96.3% for CO at the cathode. Moreover, at a current density of 0.8 A cm-2, Ni-SAs/NOMC demonstrated stable electrolysis for up to 100 h, with FEs at both the anode and cathode remaining stable at approximately 90%. In situ spectroscopy analyses and theoretical calculations identified the formation of critical intermediate species and the origin of activity improvement, guiding the development of efficient electrosynthesis of valuable chemicals. © 2025 American Chemical Society.

The exploration of the solar light absorption by a material is of great use in photonics and optoelectronics. However, the fully exploiting of the solar spectrum of well-known wide-bandgap perovskite oxides (2.7–5 eV), remains very challenging. We show that the selective occupation of Bi3+ in the octahedrally coordinated Ba2+ is responsible for creating sub-bandgap states (as low as 0.6 eV), nearly 9 times lower than pristine bandgap (5.2 eV). We reveal that the role of the 6s6p excited state of Bi3+ is as a bridge to promote the dipole-allowed band-band transition for strong absorption. Furthermore, we demonstrate the double-sided laser printing of three-dimensional optical imaging based on the photothermal effect, enabling write-once-read-many information storage with ultrahigh stability and good data retention. Our results make Ba3–xGa2O6:xBi3+ a promising candidate for photovoltaics, ferroelectrics, photocatalysis, broadband photodetectors as well as other photonic and optoelectronic applications. © 2023, The Authors.

Polyvinylidene fluoride (PVDF) nanofibers have wide applications in sensors, nanogenerators, and actuators due to their significant piezoelectric properties. However, there is still a lack of in-depth understanding the crystal structure and orientation of PVDF nanofibers, which significantly hinders further improving the piezoelectric properties of PVDF nanofibers. In this work, the effects of good and poor solvents composited mixed solvents on surface crystal structure and orientation of electrospun PVDF nanofibers were investigated using two-dimensional grazing incidence wide angle X-ray scattering (2D GIWAXS) with sample rotating, field emission-scanning electron microscope (FE-SEM), and piezoresponse force microscopy (PFM) methods. The relative β-phase content of PVDF nanofibers was enhanced when the AC volume fraction in the mixed solvents of DMF/AC or DMSO/AC increased. The evaporation rate and solubility parameters of solvents can significantly influence the surface crystal structure and morphology formation of PVDF nanofibers during electrospinning. When used the DMF/AC (6/4 v/v) solvent, the PVDF nanofibers (PVDF-DMF-6) had smooth surface morphology and had 76% of relative β-phase content. Whereas, when used DMSO/AC (6/4 v/v) solvent, the PVDF nanofibers (PVDF-DMSO-6) had fish scale-like surface morphology and had 96% of relative β-phase content. The 2D GIWAXS results revealed that the b-axis in the β-phase of PVDF-DMF-6 and PVDF-DMSO-6 nanofibers was oriented along nearly perpendicular orientation to the fiber direction, and had about 0.85 of degree of orientation. Additionally, the c-axis of γ-phases in the PVDF-DMSO-6 nanofibers was tilted approximately 64º from the fiber axis. Our results demonstrated that the orientation and size of β-phase crystals on the surface of PVDF nanofibers played significant roles in their polarization behaviors. © 2024, The Authors.
