The principle of thermochromism mainly adjusts the input of solar radiation (wavelength concentrated in 190-3000nm) energy and the output of blackbody energy through windows based on the ambient temperature. Thermochromic materials will change their transparency, absorbance, and color when the temperature changes. Thermochromic can be used as a passive design strategy to adjust near-infrared transmittance while maintaining visible light transmittance, without the need for external energy or manual operation. Therefore, thermochromic smart windows have become a hot research topic in building energy-saving windows due to their simple structure and broad application prospects.

Powder dispersion is an essential process in many industries, including pharmaceuticals, food, and cosmetics. The dispersion quality of powders in liquid systems can affect their stability, performance, and functionality. Therefore, it is vital to characterize the dispersion effect of powder to ensure the quality of the final product. In this article, we will discuss different methods to characterize powder dispersion and their significance in assessing the quality of the dispersion.

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.

Fisher's particle size is a method used to measure the particle size of granular materials, usually determined by measuring the settling velocity of particles in air or liquid. The principle of Fisher's particle size measurement is based on Stokes' law, which means that the force exerted on small particles in the medium is proportional to their diameter. The average diameter or particle size distribution of granular materials can be obtained using the Fisher particle size test.

​SiC powder is a widely used material in various applications such as electronic devices, coatings, and composites. However, its agglomeration and inadequate dispersion in aqueous media limit its efficiency. Therefore, surface modification techniques are essential to enhance the properties of SiC powder. This article discusses two methods for the surface modification of ultrafine SiC powder: PDADMAC and PSS modification and AC1830 surfactant modification.

​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.
