Summary: A novel single camera combined with Risley prisms is proposed to achieve super-resolution (SR) and field-of-view extension (FOV) imaging. A mathematical model is developed to consider imaging aberrations caused by large-angle beam deflection, and an SR reconstruction scheme is proposed using a beam backtracking method for image correction with sub-pixel shift alignment. For FOV extension, a new scheme for Risley prism scanning positions and number of image acquisitions is provided, improving acquisition efficiency and reducing image stitching complexity. Simulation and experimental results show significant resolution improvement and FOV extension, supporting the effectiveness of the proposed method.

Summary: Water management is a crucial aspect in hydrogen fuel cell operation. This study investigates the impact of various operational conditions on the formation and distribution of liquid water content within a lung-inspired PEM fuel cell. The results indicate that water initially appears in the cathode sponges and accumulates in the anode channels. Higher relative humidity, pressure, and lower temperature favor water accumulation. The design of the cathode sponge facilitates faster water evacuation.

Summary: A method using CB-KID technology to detect neutrons was proposed, where neutrons are converted into charged particles using a B-10 conversion layer, and the detector system uses delay-line method for position location. The spatial homogeneity of detector was confirmed by imaging a pattern of B-10 dot absorbers. The system demonstrated potential applications by capturing transmission images of metallic screws, nuts, and a ladybug, although detection efficiencies were low at 4 K. Further exploration of raising operating temperature towards the critical temperature of the detector is planned to improve counting rates.

Summary: The challenge of imaging through scattering media has been gradually solved by various methods. Scattering media can serve as scattering lens for sub-diffraction limit focusing and super-resolution imaging. In this work, an effective method of super-resolution macroscopic imaging for distant objects based on the Fourier-domain shower-curtain effect is proposed. The scattering media are used as screens with larger aperture to record more spatial frequency information and super-resolution image reconstruction is achieved with phase retrieval algorithm. Experimental results showed a 9.93-fold resolution improvement by sacrificing the field of view (FOV). Ptychography was further introduced to increase the space-bandwidth product as well as the compressed FOV. The proposed method shows great potential for super-resolution imaging through scattering media in macroscopy.

Summary: The analysis of interactions between micro-particles and carrier gas is crucial for studying micro-particle behavior, especially in fuel spray and spray cooling. However, optical imaging techniques have limitations that challenge existing testing methods in achieving high capturing capability and a large field of view for micro-particles simultaneously. This study proposes a technique that integrates dual-view lenses and a cGAN-ResNet joint algorithm to accurately measure micro-particles in a large field of view. The results show that the proposed method outperformed traditional methods and significantly increased the field of view.

Summary: Fourier single-pixel imaging (FSI) uses Fourier basis patterns for spatial light modulation to acquire the Fourier spectrum of the object image and reconstruct the object image via an inverse Fourier transform. The limitation of FSI is the difficulty in generating gray scale patterns at high speed. To overcome this, a method called fast FSI has been proposed, but it sacrifices spatial resolution in the pattern upsampling process. In this study, a new method is proposed that achieves full-resolution, full-field-of-view, and high-quality FSI by using an error diffusion dithering algorithm combined with two different scanning strategies to generate binarized Fourier basis patterns.

Summary: The elucidation of lithium ion transport pathways through a solid electrolyte separator is important for the development of all-solid-state batteries. Neutron imaging was performed on an all-solid-state lithium-sulfur battery using an increased Li-6 content in the anode. This allowed for differentiation between the mobile lithium ions diffusing through the cell and those initially located in the solid electrolyte, and demonstrated the lithium ion diffusion through the cell and the distribution of trapped lithium ions in charged and discharged states.

Summary: In this paper, cyclically aged lithium-ion batteries are characterized by a statistical 3D microstructure analysis and electrochemical properties. Synchrotron tomography is used to capture the morphology of the cathodes with different state of health. The 3D microstructure is quantitatively characterized by phase-based and particle-based characteristics, and the electrochemical data is correlated with the detected structural changes. This is the most extensive data set of cyclically aged lithium-ion cells including both electrochemical data and 3D structures.

Summary: In this study, neutron imaging was used to visualize and study invasion phenomena in fibrous porous transport layers (PTLs) of titanium felt under different flow conditions of gas and liquid phase. The invasion process was characterized by counter-current flow of water and air with joint imbibition and drainage processes. Neutron radiography and tomography were used to visualize the dynamics and study the static gas-liquid distributions. The results showed that the invasion occurred in repeated imbibition/drainage cycles, with frequencies depending on the flow conditions and the PTL structure.

Summary: The low rate-capability of solid-state lithium-sulfur batteries is a major obstacle to their development. Neutron imaging has revealed that sluggish ion transport within the composite cathode is the main reason for this limitation. Furthermore, concentrated lithium near the current collector, discovered through state-of-charge-dependent tomography, indicates a previously overlooked loss mechanism caused by sluggish ion transport.

Summary: One of the main advantages of metal additive manufacturing (MAM) techniques is the ability to produce components with specific microstructural features. However, microstructural defects and lack of repeatability remain major concerns. A study investigates a laser powder bed fusion (PBF-LB/M) IN718 material using Bragg-edge neutron 2D imaging (BENI) combined with electron backscatter diffraction (EBSD) analysis. BENI can detect process-induced changes in texture on a macroscopic scale, while high-resolution BENI (HR-BENI) allows for a micro-scale examination of local variations in texture and grain morphology.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
