Summary: Recent advancements in aberration correction technology have significantly improved the illumination angle in scanning transmission electron microscopy (STEM), allowing for larger depth resolution. However, minimizing low-order aberrations is crucial for three-dimensional depth sectioning with large illumination angles.

Summary: The advancement in aberration correction technology has significantly improved the depth resolution in scanning transmission electron microscopy by allowing larger illumination angles for three-dimensional analysis. Live aberration correction using atomic-resolution STEM images can save time, enable automation, and benefit axial depth sectioning and phase imaging in STEM.

Summary: This research demonstrates the self-assembly of single indium atoms and few-atom indium clusters in suspended monolayer graphene membranes, anchored to substitutional silicon impurity atoms. Scanning transmission electron microscopy (STEM) revealed that the symmetry of the indium structures is dependent on the coordination of the silicon anchors. Furthermore, electron beam irradiation in STEM enables the observation of formation, restructuring, and translation of the silicon-anchored indium structures.

Summary: This paper investigated the ability of lactic acid bacteria (LAB) and Bifidobacterium to remove acrylamide (AA) and examined the mechanism(s) of the AA removal using various microscopic techniques. The results showed that Bifidobacterium breve and Lactiplantibacillus plantarum exhibited higher acrylamide reduction rates. The study also found that both strains could tolerate low pH levels and remove acrylamide under in vitro gastrointestinal conditions.

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 investigates the mechanism of crack formation in titanium alloys with lamellar microstructure under low-cycle dwell fatigue. The accumulation of residual dislocations and local tensile stress at the α/β interfaces are found to be the key factors leading to the formation of dwell fatigue cracks.

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: In this study, the segregation of yttrium (Y) at interfaces between native MgO particles and Mg in an Mg-0.5Y alloy was investigated using state-of-the-art aberration-corrected STEM and associated spectroscopy. Two different 2-dimensional compounds (2DCs) were discovered at the Mg/{111}MgO interface and the Mg/{100}MgO interface, including two atomic layers of a face-centered cubic Y2O3 phase and an Mg(Y)-O monolayer that perfectly matched the {100}MgO plane, respectively. The formation mechanisms of the 2DCs, their effects on the nucleation potency of MgO particles, and grain refinement were discussed.

Summary: This research paper introduces a reliable and economical method for direct brazing using an active Ag-Cu-Ti filler metal that ensures effective brazing. The study focuses on the sapphire-sapphire brazing process and the formation of uniform reaction layers at the interface. The uniformity of the reaction layers decreases with increasing brazing temperature and time.

Summary: We provide an overview of the atomic structure of extended defects in wurtzite III-nitrides, specifically focusing on GaN heterostructures applicable to optoelectronic devices and power electronics. We present experimental methods to visualize and recognize these defects using aberration-corrected scanning transmission electron microscopy (STEM). Line, planar, and volume defects are imaged, with examples taken from InGaN multi quantum well heterostructures. The classification of defects and visualization methods established in this work will be valuable for researchers in this field.

Summary: In this study, the STEM Moiré GPA strain characterization method is compared to the Dark-Field Electron Holography technique on a thin film stack. Both methods show good qualitative agreement with small statistically relevant differences, and Finite Element Method simulations highlight non-uniform deformation fields in the thin lamella. The differences between the two methods can be attributed to their depth-of-field capabilities and contrast mechanisms.

Summary: This study aimed to evaluate the development of the morphology and immune function in the jejunum and ileum of squab pigeons. The results showed that the enterocyte circumference and villus morphology changed with age, and there were alterations in the levels of secretory IgA and cytokines. Overall, the changes in the intestine persisted throughout the entire period and differed between the jejunum and ileum.

Summary: This study introduces a method of 3D reconstruction using serial sectioning transmission electron microscopy (ssTEM) and compares it with focused ion beam scanning electron microscopy (FIB-SEM). The results show that there are no significant differences in structure, volume, and surface area between the two methods. This method is useful for observing large volumes of plant cells and organelles.

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.
