​Metal nanoparticles have received significant attention in various fields, including medicine, electronics, and optics. As a leading provider of high-quality metal nanoparticle products, SAT NANO understands the importance of passivation layers in metal nanoparticles and how they significantly impact their properties. This article aims to explain the significance of passivation layers in metal nanoparticles with respect to their stability, reactivity, and potential applications.

There are different methods to measure the particle size of powders, depending on the size range of the particles and the desired accuracy of the measurement. Here are some common techniques:

Nanotechnology has presented innovative solutions to various sectors such as medicine, electronics, and energy. Nanomaterials are a fundamental unit in nanotechnology that have unique features, including their size, shape, and crystallinity, which make them a desirable material.

Alpha and Gamma alumina are two of the most widely used types of alumina in various industrial applications. Though both types are derived from the same raw material, they differ in terms of properties, structures, and behaviour, making them suitable for distinct applications. In this blog post, we will explore the differences between alpha and gamma alumina and how these differences impact their functionality.

In the current era of miniaturization of electronic devices, rapid development of the new energy industry, and continuous improvement of LED lighting power, "heat dissipation" has become a core bottleneck restricting product performance upgrades and lifespan extensions. Traditional thermal conductive materials either have insufficient thermal conductivity efficiency, poor compatibility, and are prone to settling, making it difficult to meet the needs of high demand scenarios. Nano aluminum oxide, with its unique nanoscale structure and excellent thermal conductivity, is becoming a "performance breakthrough" in the field of thermal conductivity, providing efficient heat dissipation solutions for multiple industries such as electronics, new energy, and lighting.

The crystal structure of nano iron oxide is hexagonal, and the lattice parameters change with the decrease of particle size. When the particle size is large (usually larger than tens of nanometers), iron oxide exhibits a typical α- The Fe2O3 structure, also known as hematite structure, is red in color. This is because typical α- The Fe2O3 structure has a high reflectivity for visible light, absorbing shorter wavelengths (blue-green) in visible light, leaving only longer red wavelengths observed.
