Stealth technology has come a long way since its inception during World War II. The use of radar-absorbing materials and electromagnetic signature reduction techniques has helped to make aircraft, ships, and vehicles less detectable to the enemy. However, the holy grail of stealth technology has always been invisibility – the ability to render an object completely invisible to the naked eye. In this blog post, we will examine the potential of nanomaterials to revolutionize the field of stealth technology by creating invisible cloaks.

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.

​Dispersants or dispersing agents are substances that aid in the uniform distribution of particles or materials such as nanoparticles in a medium. Dispersing nanoparticles can be a challenging task due to their high surface area, tendency to agglomerate and their small size. In this article, we will discuss the basic principles of using dispersants in dispersing nanoparticles.

​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. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.

Scanning electron microscopy can be divided into thermal electron emission type and field emission type according to the different ways of electron generation. The filament used for thermal electron emission type is mainly tungsten filament electron microscopy. Field emission type The distinction between hot field emission and cold field emission.
