Summary: This study provides the first ultrastructural images of pathological changes in the sensory setae of the first antenna and inner tissues in different stages of Lepeophtheirus salmonis development after sound exposure. The response to sounds and associated injuries in the lice sensory organs could potentially lead to the development of a bioacoustics method for preventing lice infection and treating affected salmons.

Summary: This study evaluates two advanced, automated crystal orientation mapping techniques suitable for nanocrystalline materials. The comparison shows that TEM-PED is more reliable for characterizing grains oriented along low-index zone axes, while SEM-TKD is better at detecting small misorientation between grains, providing better quantification and statistical analysis of grain orientation. Both techniques are complementary tools for nanocrystalline materials and can be selected based on analysis requirements, as they have competitive performance in terms of angular resolution and texture quantification.

Summary: Epitaxial transition metal nitrides (TMNs) are a new class of crystalline thin film metals that can be integrated with common group III-nitride semiconductors. This study used high-resolution transmission electron microscopy to identify different phases of tantalum nitrides with N-sublattice ordering, revealing Ta-deficient films with specific planar defects. These findings lay the foundation for the application of this epitaxial TMN material in new electronic and superconducting device structures.

Summary: Halide perovskite is a unique dynamical system with complex structural and chemical processes, but its intrinsic instability makes real-time investigation challenging. However, our research reveals that atomically thin carbon materials can stabilize ultrathin halide perovskite nanostructures and enable atomic-level visualization of their movement. Protected by carbon shells, these structures maintain their integrity under high electron dose rate and exhibit unusual dynamical behaviors. Our work provides a new method to protect beam-sensitive materials and study structure dynamics of nanomaterials.

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: Topological textures of ferroelectric polarizations have potential applications in future information technology. However, energy losses and deviations from stability can affect the symmetry and shape of these textures. In this study, we investigated the domain structure of bismuth tungsten oxide thin films grown on SrTiO3 substrates using advanced microscopy techniques. We discovered a hidden phase with a different polarization orientation that promotes the formation of flux closure domains, bringing us one step closer to an isotropic two-dimensional polar material.

Summary: YFeO3 thin films exhibit changes in antiphase boundaries under the influence of Y-Fe antisite defects and strain, displaying polar and bistable characteristics. Density functional theory demonstrates that the presence of Fe-Y antisites significantly decreases the switching barrier.

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: Thin target foils of Ce-140 and Ce-142 were fabricated using physical vapour deposition technique for studying nuclear reaction dynamics with heavy ion beams. The reactive nature of cerium led to oxidation of thin films during fabrication, which was addressed by sandwiching them between layers of C-nat. Characterization techniques including SEM, EDS, FTIR, XRD, and RBS were utilized to determine surface morphology, composition, and thickness of the prepared targets. The results matched well with the data provided by the isotopic material supplier.

Summary: The typical defect reactions at the metal/oxide interface explaining the growth and breakdown of passive oxide films in corrosion include the creation of metal and oxygen vacancies. This study introduces a new mechanism of oxygen injection into the metal, with fast passivation in the NiCr alloy showing a significant oxygen injection at a fast growth rate. The addition of Mo promotes the formation of the corundum phase in the outer oxide layer for NiCrMo, changing the transport mechanism of oxygen through the oxide film and across the metal/oxide interface.

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: 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.
