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.

In our modern world, pollutant emission and contamination in the environment are rapidly increasing, which has led to a surge in the use of nanoporous adsorbent materials. These materials are essential in adsorbing gases, waste, metals, and organic compounds. In this article, we will explore the most commonly used nanoporous adsorbent materials.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

​The use of silver-based materials for their strong antibacterial properties has long been recognized, but concerns about their potential toxicity have led to the need for alternative, safe, and effective antibacterial systems. Against this backdrop, a team of researchers has developed a novel synergistic antibacterial system using arginine-modified chitosan (ACS) composite silver-loaded MMT (AgNPs@MMT) for food preservation. This article explores this promising solution in detail.

Nano iron oxide powder is a popular material in various industries due to its unique properties. When the particle size decreases to nanoscale, the material becomes highly functional in areas such as catalysis, magnetic materials, and biomedical applications. SAT NANO is a leading supplier of high-quality nanomaterials in the market, and their 50 nanometer nano iron oxide powder is no exception. In this blog, we will explore some of the benefits of using SAT NANO's 50 nanometer nano iron oxide powder.

​The difference in cohesive force between different powders is due to the type and strength of interparticle forces (van der Waals forces, capillary forces, electrostatic forces, etc.), and its core influencing factors include particle size, surface roughness, moisture content, and material properties, resulting in cohesive force that can span multiple orders of magnitude (from 10 ⁻⁶ N to 10 ⁻¹ N). This difference can be quantitatively described through the aggregation feature index, surface tension, and roughness correction model.
