​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.

SAT NANO is specialized in manufacturing top-quality Zinc Ferrite Nanopowder, and their production process is innovative. This revolutionary method, known as "pulsed laser ablation" is a green and environment-friendly technique that converts Zinc Ferrite Target into powder form using a high-energy laser. Compared to the traditional methods such as hydrothermal, co-precipitation, and microwave-assisted methods, the pulsed laser ablation method is faster, greener as it doesn't produce waste and the produced nanomaterial is pure with fewer defects.

Silicon carbide powder has become a popular material in various industries due to its unique properties like high hardness, high wear resistance, and excellent thermal conductivity. There are two types of silicon carbide powder, Alpha SiC and Beta SiC. In this article, we will explore the differences between the two types of silicon carbide powder and their applications.

​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.

Silicon dioxide powder is widely used in various industrial fields due to its unique properties. However, as a powder, it suffers from drawbacks such as low reactivity, poor dispersion, and low surface energy. Surface modification is a way to improve the properties of silicon dioxide powder and enhance its performance in various applications. In this article, we will discuss a surface modification method for silicon dioxide powder using a silane coupling agent and its effect on the properties of silicon dioxide powder.

​Transmission electron microscopy (TEM) is an indispensable research tool in fields such as materials science and nanotechnology. For researchers who are new to TEM, understanding its basic principles and operations is crucial for efficient utilization of this equipment. TEM testing mainly focuses on the microstructure characteristics of materials, including element distribution, phase composition, crystal defects, etc. These characteristics are manifested at the microscopic level as the size, shape, distribution of different phase grains, as well as the density and distribution of crystal defects. Through TEM, researchers can gain a deeper understanding of the internal structure of materials, thereby evaluating their properties and potential applications.
