Scanning electron microscopy (SEM) is a crucial tool in the field of materials science, providing valuable insights into the microstructural characteristics of materials. Unfortunately, SEM images often suffer from blurriness caused by improper hardware calibration or imaging automation errors, which present challenges in analyzing and interpreting material characteristics. Consequently, rectifying the blurring of these images assumes paramount significance to enable subsequent analysis. To address this issue, we introduce a Material Images Deblurring Network (MIDNet) built upon the foundation of the Nonlinear Activation Free Network (NAFNet). MIDNet is meticulously tailored to address the blurring in images capturing the microstructure of materials. The key contributions include enhancing the NAFNet architecture for better feature extraction and representation, integrating a novel soft attention mechanism to uncover important correlations between encoder and decoder, and introducing new multi-loss functions to improve training effectiveness and overall model performance. We conduct a comprehensive set of experiments utilizing the material blurry dataset and compare them to several state-of-the-art deblurring methods. The experimental results demonstrate the applicability and effectiveness of MIDNet in the domain of deblurring material microstructure images, with a PSNR (Peak Signal-to-Noise Ratio) reaching 35.26 dB and an SSIM (Structural Similarity) of 0.946.

Operando X-ray diffraction (XRD) is an important characterization tool for real-time monitoring of structural changes in materials under different reaction conditions. In this study, we developed a laboratory-based diffractometer that could capture a full XRD spectrum within 10 s. The instrument has several advanced features. First, it uses a Ga–In alloy metal-jet X-ray source, thereby achieving high X-ray flux with a brightness of up to 3.0 × 1010 photons/(s·mm2·mrad2). Second, it employs an ellipsoidal mirror with a multilayer coating to produce quasi-parallel monochromatic light characterized by a divergence of 0.6 mrad and an energy resolution of 5.9 × 10−3. Third, it is equipped with a high-efficiency, high-signal-to-noise-ratio Pilatus 3R 1M detector for collecting diffraction signals. These features make the developed instrument applicable in studying rapid phase transitions in lithium-ion batteries, especially under extremely fast charge–discharge conditions. The data quality was comparable to that of synchrotron radiation XRD.
