Summary: This study presents a novel nonlinear two-dimensional (2D) warped discrete Fourier transform (WDFT) amplitude demodulation method for higher-resolution measurements. The method is applied to the nonlinear 2D amplitude demodulation of fringe-wave fields acquired by a deformed Mach-Zehnder interferometer. Experimental validation demonstrates the efficiency of the proposed algorithm for amplitude demodulation with dense sampling points in the central part of the envelope.

Summary: This paper presents first-principles design and calculation on the electronic properties and crystal structure of Cs-doped Sn-based 2D HOIPs. The results show that Cs doping can decrease the band gap and effectively reduce the carrier effective mass, indicating the potential of Cs-doped Sn-based 2D HOIPs as a substitute for conventional Pb-based 3D HOIPs in solar cells.

Summary: By partially replacing FA with MA, a FA-rich Q-2D perovskite with enriched larger n phases was formed, leading to improved environmental stability and solar cell performance. The (BA)(2)(FA(0.8)MA(0.2))(3)Pb4I13 perovskite film exhibited the best stability, and the photovoltaic device based on it achieved a conversion efficiency of 14.2%.

Summary: In this study, the phase unwrapping problem is formulated as a pixel-wise semantic segmentation problem, and a high-resolution deep learning network named HRNet is employed to infer an integer multiple of 2n for every pixel to remove phase discontinuities. The effectiveness and superiority of the proposed method are verified through comparisons with other methods on simulated and real data.

Summary: The in-plane anisotropy of molybdenum trioxide (MoO3) has attracted increasing attention from the scientific community, with observed properties stemming from the material's anisotropic refractive index and elastic constants. Raman and micro-reflectance measurements were used to determine the angular dependence of the refractive index of thin MoO3 flakes, while the directional dependence of the MoO3 Young's modulus was studied using the buckling metrology method. It was found that MoO3 exhibits one of the largest in-plane anisotropic mechanical properties reported for 2D materials.

Summary: This work introduces a mixed stitching interferometry method that corrects stitching angle errors using one-dimensional profile measurements. By averaging multiple measurements and using multiple profiles, the repeatability error is reduced. The method is compared with global algorithm-based stitching and the error is reduced to one-third. High-precision one-dimensional profile measurements such as NOM can further improve the accuracy of the method.

Summary: In this study, 2D GeSe was introduced into the active layer of organic solar cells for the first time, adjusting the morphology of the active layer and improving the crystallinity and molecular orientation of the acceptor molecule ITIC. This led to the formation of efficient charge transport networks and reduced carrier recombination, enhancing the power conversion efficiency and lifetime of the solar cells. Additionally, the interaction between 2D GeSe and ITIC was revealed through first-principles calculation, providing insights for morphology regulation and exploring the interaction between 2D materials and organic molecules.

Summary: Due to the large size of the Sun's heliosphere and sparse spacecraft measurements, numerical modeling is crucial for predicting solar wind conditions where measurements are lacking. This study utilizes a 2D model to simulate solar wind propagation and creates a dataset of solar wind in the outer heliosphere. The model has been continuously running from 1995 to the present, and the results are available for free online. Validations with observation data demonstrate the effectiveness of the model.
