Nanopowders have become a crucial element in the manufacturing industry, particularly in the production of high-performance materials. One of the properties that make nanopowders valuable is their thermal conductivity. In this article, we will explore the different types of nanopowders with thermally conductive properties that can be used in various applications.

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.

Antibiotics refer to drugs that can inhibit bacterial growth, damage their living environment, and effectively and continuously exert their effects. Antibacterial agents are divided into two categories: organic antibacterial agents and inorganic antibacterial agents. Among them, organic antibacterial agents include natural and synthetic types, while inorganic antibacterial agents mainly include metals, metal ions, and oxides. The commonly referred to antibacterial measures include inhibition, killing, elimination of toxins secreted by bacteria, and prevention. Due to the strong thermal stability, long-lasting functionality, and safety and reliability of inorganic antibacterial agents, coupled with the development of ultra-fine technology in recent years, nanoscale inorganic antibacterial agents can be mass-produced and blended or composite into chemical fibers, ensuring the industrialization of antibacterial chemical fibers.

Titanium dioxide is a versatile material that finds applications in multiple industries including paints, coatings, plastics, cosmetics, and pharmaceuticals, among others. However, the surface properties of titanium dioxide often limit its performance in various applications. To overcome this limitation, researchers have developed several methods for surface modification of titanium dioxide. In this article, we will explore some of the most effective methods for surface modification of titanium dioxide.

As an important physical property of powders, specific surface area refers to the total surface area per unit mass of oxide powder. And its size is influenced by various factors. Firstly, particle size is an important factor affecting the specific surface area of powders. The smaller the particles, the larger the specific surface area. This is because the smaller the particle size, the larger the surface area of each individual particle, thereby increasing the total surface area per unit mass of powder.

​Graphene coated copper and silver coated copper have essential differences in conductivity, each with its own advantages and disadvantages, and their applicable scenarios are also different.
