Summary: In this study, we developed an optical biosensor based on an all-dielectric metasurface with broken symmetry. The biosensor exhibited excellent performance, thanks to the high-Q quasi-bound states in the continuum (qBICs) and the efficient field confinement. It has potential applications in extreme biochemical sensing, such as COVID-19 detection at ultralow concentrations.

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: In this study, an in situ transmission electron microscopy (TEM) heating system was used to investigate the morphological changes of cubic Ag nanoparticles (NPs) and Ag-based core-shell structures induced by sublimation, as well as the influence of shell coverage on thermal stability. It was found that large Ag NPs (>50 nm) showed a three-stage sublimation-induced morphological change, while small Ag NPs (<30 nm) showed a uniform sublimation. The sublimation process of core-shell NPs started at stage II, and the thermal stability was enhanced by carbon shell passivation.

Summary: By utilizing low dose in situ high-resolution transmission electron microscopy imaging, we directly observed the nucleation and growth process of the phase transition from orthorhombic gamma-CsPbBr3 to cubic alpha-CsPbBr3 in nanoplates during heating. The normalization of (PbBr6)(4-) octahedra was observed, and phase transition pathways (edge-to-center growth and island growth) were summarized. Phase fluctuation/recovery occurs during the phase transition process. Additionally, we investigated the thermal degradation caused by high temperature, which was found to occur from the outer edge to the center region. This work provides a microscopic basis for the understanding of phase transition and its application in devices.

Summary: In the past decade, the applicability of atom probe tomography (APT) has been extended to a wide range of materials including semiconductors and insulators. However, APT can only provide information about composition, making it challenging to analyze the correlation between composition and other material properties. Therefore, researchers worldwide have been combining APT with other microscopy methods to understand the composition-property interrelationships at the same position of the sample. This article provides an overview of these efforts and presents three examples of opportunities in materials science when using correlative microscopy with APT.

Summary: We directly imaged the laser-induced cavitation of micron and nanoscale bubbles using Movie-Mode Dynamic Transmission Electron Microscopy (MM-DTEM). The collapse of isolated nanobubbles was observed to occur in less than 50 ns, while larger bubbles (approximately 2-3 μm) grew and collapsed in less than 200 ns. Bubbles in close proximity to each other exhibited more complex behavior, with longer lifetimes and a higher likelihood of rebounding after collapse.

Summary: By combining transmission electron microscopy, first-principles calculations, and cathodoluminescence spectroscopy, we demonstrate unexpected strong interfacial interactions at the incoherent AlN/Al2O3 (0001) interface with a large mismatch, which result in the formation of misfit dislocation networks and stacking faults rarely observed at other incoherent interfaces. The strong interfacial interactions significantly tailor the interfacial atomic structure and electronic properties, leading to a reduced band gap and strong interfacial ultraviolet light emission. These findings suggest the potential of incoherent interfaces in developing novel heterojunction materials and devices.

Summary: The study found that the decline of native crayfish biodiversity caused by invasive crayfish introductions has been well documented, but the fate of their associated biota has been overlooked. The presence of native European branchiobdellids (annelid worms that are ectosymbionts of crayfish) was monitored in three localities in Czech Republic. The results showed that branchiobdellids were not detected in areas with invasive signal crayfish but without the native noble crayfish, and the number of branchiobdellids on signal crayfish was significantly lower compared to the native noble crayfish.

Summary: Crustaceans, especially decapods like shrimp, crabs, and lobsters, are a diverse group of organisms that are commercially and ecologically important. They are affected by various environmental factors that can fluctuate beyond their optimal ranges and influence their immune system and health. Understanding the mechanisms by which stressors affect immune parameters in decapods, particularly the abiotic components of the environment, could help mitigate the harmful effects on their production.

Summary: The killer shrimp Dikerogammarus villosus is an invasive alien amphipod that has spread across freshwater rivers and streams in Europe, causing ecological and economic impacts. Our study analyzed 96 European time series and identified trends in the population dynamics of D. villosus, as well as its impact on ecological communities. We found that D. villosus is well-established in European waters and its abundance significantly alters recipient community metrics. However, early detection methods are needed to address the cryptic initial introductions of D. villosus.

Summary: Biological invasions pose a growing threat to ecosystems, biodiversity, and socio-economic interests. However, there are variations in classifications and definitions of invasive species among European Union member states, leading to differences in the number and proportion of reported invasive species. Using Germany as a case study, this research highlights the gaps in invasive species classifications and suggests that the lower number of reported invasive species in Germany may be attributed to differences in classifications, variations in research effort and focus, and diverse national priorities. This underreporting may be a result of a focus on economic growth, which may have taken precedence over addressing the potential ecological and economic impacts of invasive species.
