​Nanoparticles are widely used in various fields such as drug delivery, imaging, and materials science. Coatings on the surface of nanoparticles can affect their properties and performances. Therefore, it is essential to measure the thickness of coatings to understand their effects on nanoparticles. In this blog post, we will introduce several methods for measuring the thickness of coatings on nanoparticles.

​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.

When it comes to powdered materials, density is an essential parameter that determines their physical and chemical properties. Different methods are employed to measure powder density, including loose bulk density, tapped density, true density, apparent density, bulk density, and compacted density. This article will discuss these parameters, and how they affect the properties of powdered materials.

Particle size analysis is a technique used to study the size distribution of particles in a sample. It is a vital analysis technique in many industries, such as pharmaceuticals, food, chemical, and environmental due to the importance of controlling particle size for the product's performance. However, the accuracy of the particle size analysis results depends significantly on the instrument's precision and how well the sample preparation and measurement process is executed. In this blog post, we will discuss the factors that can affect the accuracy of particle size analysis.

Nanosilver powder, along with flake-shaped and spherical silver powders, is mainly used in conductive pastes for polymer conductive materials. Depending on the oil absorption and conductivity requirements, different silver powders can be mixed and used. They have a wide range of applications in various fields such as scientific research, industry, and biotechnology. Some people think that they can disperse nanosilver powder directly in water after purchasing it, but this is not feasible. It can easily cause the powder to agglomerate. Effective dispersion of nanosilver powder can be achieved through the following methods:

Nanoparticles are microscopic particles with unique properties that can be tailored for specific applications. Nanoparticles are used in various fields, including medicine, engineering, and electronics. One of the properties of nanoparticles is magnetic property. This article will delve into the world of magnetic nanoparticles, discussing which nanoparticles have magnetic properties.
