Summary: Phase transformation is a universal phenomenon in materials and plays a crucial role in determining their properties. However, accurately segmenting different phases in complex material systems remains a challenge. This study successfully developed a deep-learning tool that can automatically segment intertwined phase domains in cathode materials for lithium-ion batteries, outperforming traditional methods and providing quantitative insights into the correlation between multiple phases formed during battery operation.

Summary: The study found that as the temperature increases, the spacing of dislocation networks in the gamma/gamma' interface decreases, while the minimum creep rate increases non-linearly. This is due to the enhanced dislocation-climb in the interface and gamma'-cutting by a <010> superdislocations.

Summary: This study reveals the correlations between grain architecture, Li transport pathways, and phase transitions in Ni-rich layered cathodes using in situ transmission electron microscopy. The results show that Li ions are extracted through tortuous paths connecting the Li-containing a-b planes in the crystals, and the grain boundary resistance depends not only on the misorientations of the neighboring grains.

Summary: The nutritional condition of seed mussels used in New Zealand's Greenshell mussel aquaculture industry shows high variability, which may contribute to the marked variation observed in spat performance. Environmental factors that limit feeding during harvest and transport of spat are likely influencing the quality of spat used by the industry. Measures to improve the quality of wild spat supply, such as testing nutritional condition and developing nursery culture methods and artificial spat feeds, are needed.

Summary: The structural modulations in multiferroic Bi4.2K0.8Fe2O9+delta (BKFO) nanobelts have been uncovered by scanning transmission electron microscopy (STEM). The displacive modulations can be decomposed into a transverse wave and a longitudinal wave, whose amplitudes and phases are layer-dependent. This study may help to understand and optimize the magnetoelectric coupling effect in BKFO.

Summary: This study investigates the formation of boron carbide superhard particles through a liquid-phase reaction at high pressure and high temperature. The synthesized particles exhibit a rhombic hexecontahedron morphology with twelve five-vertex stars. Electron microscopy and X-ray diffraction were used to analyze the crystal structure of these particles, revealing multiple cycling twinning rather than quasi-crystalline symptoms. The specific shape of the particles is explained by the decrease of surface energy during formation at high pressure and high temperature.

Summary: Imaging techniques were used to study the three-dimensional microanatomy and spatiotemporal relationships of cells, extracellular matrix, and vasculature at the corneo-scleral limbus of developing and mature chicken eyes. Results showed the development of structures similar to Palisades of Vogt, associated with characteristics of stem cells, and direct cell-cell associations between corneal epithelial and stromal cells.

Summary: In this study, a machine learning planner was used to control the diameters of single-walled carbon nanotubes (SWCNTs), successfully optimizing synthesis conditions to maximize the SWCNT diameters within specific ranges. The optimized growth experiments showed high selectivity compared to unoptimized growth experiments. Interestingly, significantly different synthesis conditions were found for maximizing two diameter ranges, despite their relative closeness.

Summary: Bayesian optimization (BO) has shown effectiveness in guiding autonomous and high-throughput experiments in materials science. This study evaluated the efficiency of BO across five different experimental materials systems, finding that Gaussian Process (GP) with anisotropic kernels and Random Forest (RF) performed well in BO, outperforming commonly used GP with isotropic kernels. GP with anisotropic kernels demonstrated robustness, while RF is a close alternative with advantages such as lack of distribution assumptions, lower time complexity, and easier initial hyperparameter selection. The benefits of using GP with anisotropic kernels in future materials optimization campaigns were also highlighted.

Summary: This study investigated the dynamics of NO2 and NH3 adsorption on monolayer WS2 using spectroscopic techniques, revealing the influence of gas concentration and temperature on photoluminescence emission energies, as well as the correlation between lattice defects and gas adsorption. The results suggest that lattice defects, such as sulfur vacancies, play a key role in gas adsorption on WS2, with gases like NO2 and NH3 potentially contributing to the creation of defects with increasing temperature. This research provides valuable insights for the development of spectroscopy-based gas sensors using 2D materials.
