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...

XRD is an important means of characterizing phases. Strictly speaking, it can determine the existence of a certain phase, but cannot determine the absence of a certain phase, making it easier to distinguish between truth and falsehood. So, what is its detection limit? Firstly, we must emphasize that XRD analysis of elemental content is very inaccurate. If we have to say what the detection limit is...

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 ...
