With the continuous development of nanotechnology, nano metal ultrafine powders have been increasingly widely used. However, during storage and transportation, nano metal ultrafine powders also face some problems, such as poor thermal stability and easy oxidation and heating. Therefore, we must take some measures to ensure the safe storage and transportation of nano metal ultrafine powders. In ord...

Synthesis of Carbon Quantum Dots 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. Top-down approach Top down method: lase...
