​Transmission electron microscopy (TEM) is an indispensable research tool in fields such as materials science and nanotechnology. For researchers who are new to TEM, understanding its basic principles and operations is crucial for efficient utilization of this equipment. TEM testing mainly focuses on the microstructure characteristics of materials, including element distribution, phase composition, crystal defects, etc. These characteristics are manifested at the microscopic level as the size, shape, distribution of different phase grains, as well as the density and distribution of crystal defects. Through TEM, researchers can gain a deeper understanding of the internal structure of materials, thereby evaluating their properties and potential applications.

​Metal nanoparticles have received significant attention in various fields, including medicine, electronics, and optics.

This article aims to explain the significance of passivation layers in metal nanoparticles with respect to their stability, reactivity, and potential applications.

Colloidal gold refers to a colloidal system formed by suspending nanoscale gold particles in an appropriate solution. The size of gold particles typically ranges from 1 to 100 nanometers.

Aluminum nitride is a ceramic material with high melting point, hardness, and thermal conductivity, as well as good thermal stability and corrosion resistance. Its crystal structure is hexagonal, thus requiring high temperatures and pressures in the preparation process. Due to these excellent properties, aluminum nitride has been widely used in high-temperature electronic devices, thermal conductivity materials, and other fields.

A groundbreaking study published in Advanced Functional Materials on February 16, 2025, unveiled a novel MXene thin film protected by reduced graphene oxide (rGO), termed rGM. This innovative film boasts exceptional charge transfer capabilities and the remarkable ability to stay stable in the ambient air. The protective rGO layer effectively shields the conducting layer of MXene from air oxidation, significantly enhancing air stability. After 40 days of exposure to air at 25°C and 40% relative humidity, the membrane resistance of the rGM film (135.9±2.3Ω/sq - 312.6±4.5Ω/sq) showed negligible amplification compared to the pure MXene film (145.0±2.3Ω/sq - 2,152.8±6.8Ω/sq).
