As one of the most important characterization parameters of nano powder, particle size directly affects the physical and chemical properties of the powder, and then affects the performance of the final product. Therefore, its detection technology is an important tool for industrial production and quality management, and plays an irreplaceable role in improving product quality, reducing production costs, and ensuring product safety and effectiveness. This article will start from the principle and compare three common methods for powder particle size detection: electron microscopy, laser particle size analysis, and X-ray diffraction line width method, and analyze the advantages, disadvantages, and applicability of different particle size testing methods.

Osteoarthritis (OA) is a prevalent disease characterized by subchondral bone fracture, and there is no accurate and specific treatment yet available. Recently, the research team has synthesized a new multifunctional scaffold that can potentially solve this problem. Using photo-polymerized modified hyaluronic acid (GMHA) as a substrate and hollow porous magnetic microspheres (HAp-Fe3O4) as the base, they designed a scaffold with optimum properties for subchondral bone repair.

In the world of powders, particle size is one of the key indicators for measuring their performance. Let's talk about an important concept - D50.

​The preparation of SEM nano powder samples usually requires the following steps:

​As we continue to explore the world of materials science, we are constantly gaining a deeper understanding of the materials that make up our everyday lives. In recent years, a new class of materials has emerged - low-dimensional materials. These materials come in several varieties, ranging from zero-dimensional (0D) to two-dimensional (2D) materials. In this article, we will explore the different types of low-dimensional materials and their unique properties.
