Summary: A novel image processing method based on scanning electron microscopy images and ellipse fitting is developed to quantitatively characterize the shape and orientation of enamel prisms. Color coded orientation maps provide quick insight into the microstructure of enamel and allow for statistical analysis of prism arrangement. This method contributes to the quantitative investigation of prism arrangement in dentistry research and evolution biology.

Summary: This study investigated the characteristics of the surface layer of surgical resected disc specimens in human temporomandibular joint osteoarthritis cases using transmission electron microscopy. The findings showed that the surface was covered with fibroblastic and histiocytoid cells, collagen fiber bundles and collagenous matrix were exposed, and fibrinous dense material was observed. Collagen bundles were rich around capillary vessels, and synovial surface cells exhibited features of activated macrophages with vacuole formation.

Summary: The objective of this study was to examine the morphology and histological features of the small and large intestines of the six-banded armadillo (E. sexcinctus). The results showed that the small intestine has three parts and the typical four layers of tubular organs, while the large intestine has similar histological subdivisions as the small intestine but with some specializations.

Summary: Single-cell analysis is a promising field in life sciences, allowing the exploration of fundamental laws of physiological and pathological processes. Atomic force microscopy (AFM) is a powerful tool capable of non-destructive imaging and quantitative measurement of structural and mechanical properties of single living cells. AFM has been widely used in cancer research, providing unique insights into tumor pathogenesis from a biomechanical perspective.

Summary: The researchers optimize the application of scanning capacitance microscopy in GaN-based HEMT structures through experimental setup and imaging conditions. They find that a sharp probe coated with conductive doped diamond, a large spring constant, and positioning close to the edge and Ohmic contact of the sample can improve contrast. In addition, applying a dc bias in addition to an ac bias is more effective in depleting the 2DEG in the AlGaN/GaN heterostructure. The selected ac bias has no significant impact on contrast.

Summary: By using finite element analysis, the influence of solution viscosity on the shape variation of the droplet at the tip during the movement of the pipette in scanning electrochemical cell microscopy (SECCM) was studied. It was proved that increasing solution viscosity is helpful in reducing the shape variation of the droplet at the tip. Experimental results showed that increasing solution viscosity improves scanning success rates and quality, and effectively lowers the mean square error (MSE) of the scanning results. The results also demonstrated that SECCM can achieve higher imaging speeds when the solution's viscosity increases.

Summary: Among the potential applications of topological insulator materials, the development of tunable plasmonics at THz and mid-infrared frequencies for quantum computing, terahertz detectors, and spintronic devices is particularly attractive. However, understanding the relationship between nanoscale crystal structure and the properties of plasmonic resonances remains elusive. In this study, energy-gain EELS analysis was used to characterize collective excitations in the topological insulator material Bi2Te3 and correlate them with the underlying crystalline structure. The findings demonstrate the potential of energy-gain EELS analysis in accurately mapping collective excitations in quantum materials, which is crucial for the development of new tunable plasmonic devices.
