The passivation layer of metal nanoparticles refers to a thin film or protective layer coated on the surface of metal nanoparticles. It usually consists of a compound, such as an oxide, sulfide, or organic compound. This passivation layer can alter the surface properties of metal nanoparticles and provide protection and stability.

Researchers have made a breakthrough in the development of carbon nanotube (CNT) reinforced aluminum composites by utilizing ultra-short CNTs with unique intra-crystalline dispersibility. The nanoscale carbon nanotubes are uniformly distributed within the ultra-fine aluminum grains. When compared with typical CNT/Al composites with inter-granular CNT dispersion, this intra-crystalline carbon nanotube/aluminum composite has a stronger ability to anchor and maintain dislocations, resulting in enhanced strength and ductility. This innovative intra-crystalline dispersal strategy provides a new avenue for developing strong and tough nanocarbon reinforced metal-based composite materials. The research has been published recently in a prestigious academic journal.

The synthesis of carbon quantum dots can be mainly divided into two categories: top-down method and bottom-up method. Through the pre-treatment, preparation, and subsequent processing, carbon quantum dots can be controlled in size, passivated on the surface, doped with heteroatoms, and nanocomposites to meet the requirements.

Particle rearrangement and densification: In liquid-phase sintering, the generation of liquid phase and particle rearrangement are key steps in densification. Small particles have a large specific surface area and surface energy. After the liquid phase is generated, the solid phase is wetted by the liquid phase and infiltrates into the gaps between particles. If the amount of liquid phase is sufficient, the solid phase particles will be completely surrounded by the liquid phase and approximate a suspended state. Under the surface tension of the liquid phase, they will undergo displacement and adjustment of position, thus achieving the most compact arrangement. At this stage, the density of the sintered body increases rapidly

Nanosilver powder, along with flake-shaped and spherical silver powders, is mainly used in conductive pastes for polymer conductive materials. Depending on the oil absorption and conductivity requirements, different silver powders can be mixed and used. They have a wide range of applications in various fields such as scientific research, industry, and biotechnology. Some people think that they can disperse nanosilver powder directly in water after purchasing it, but this is not feasible. It can easily cause the powder to agglomerate. Effective dispersion of nanosilver powder can be achieved through the following methods:
