Class I and Class II materials are two fundamental concepts in the field of materials science, which are used to describe the crystal structure types of materials and are often applied in the research of materials such as semiconductors and metals. So, how do we distinguish between Class I materials and Class II materials? A simple method is to distinguish based on the density of the material. Com...

Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Trad...

The specific surface area of a powder is an important physical property, which refers to the total surface area (in square meters) of an oxide powder per unit mass (in grams). The size of the specific surface area is related to factors such as particle size, shape, and porosity of the powder. Generally speaking, the smaller the particles and the higher the porosity, the larger the specific surface...

High entropy alloys (HEAs) are a new type of structural material composed of five or more elements in nearly equal atomic ratios, exhibiting characteristics such as high entropy effect, lattice distortion effect, slow diffusion effect, and cocktail effect. Laser cladding technology can significantly improve the hardness, wear resistance, and corrosion resistance of HEAs cladding layers due to its ...
