With the rapid development of modern industry and technology, different industries have increasingly high performance requirements for powder materials. In addition to having extremely low impurity content, fine particle size, and narrow particle size distribution, powder materials also need to have a certain particle morphology. Spherical powders have been widely used in high-end industries such ...

In transmission electron microscopy (TEM) analysis, the primary and crucial step in obtaining a high-quality image that can be interpreted reasonably is sample preparation. Inappropriate sample thickness, poor conductivity, or damage introduced during sample preparation can directly lead to abnormal electron beam penetration, image distortion, and even sample scrapping. TEM sample requirements ① T...

1.Characterization of particle size and distribution Dynamic Light Scattering (DLS): DLS is one of the most commonly used techniques for measuring the particle size and distribution of nanoparticles in suspensions. It calculates the hydrodynamic diameter of particles by measuring the time-dependent light scattering intensity fluctuations caused by Brownian motion of particles. DLS can also provide...

With the increasing demand for high thermal conductivity materials, filled thermal conductive polymer composites have good application prospects. The performance of thermal conductive composite materials largely depends on the selection of thermal conductive fillers. Aluminum oxide (Al2O3)is a common ceramic filler with high hardness and good thermal conductivity, and is a commonly used choice to ...
