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.

As a researcher with over two decades of experience in material science, I have seen firsthand the challenges that come with synthesizing consistent, high-quality metal oxide nanoparticle suspensions. The struggle is real—agglomeration, where those tiny, powerful particles stick together, can ruin the very properties we work so hard to achieve.

There are three main methods for preparing single-walled carbon nanotubes: arc method, laser ablation method, and chemical vapor deposition (CVD) method.

Nanotechnology is reshaping conventional industries by offering advanced materials with improved strength, durability, and functionality. This blog will shed light on how SAT NANO is revolutionizing the industry with top-quality 30nm aluminum oxide powder.

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
