Transmission Electron Microscope (TEM) Transmission electron microscopy uses an electron beam that penetrates a sample to image, which requires the sample being observed to be "transparent" to the incident electron beam. Transmission electron microscopy is widely used in materials science and biology. Since electrons are easily scattered or absorbed by objects, the penetration is low, and the dens...

In the process of powder storage, transportation and use, it is often hoped that the nano-aluminum powder exhibits low activity and is less affected by external environmental factors (temperature, humidity, etc.), so that the product has stable performance for a long time. On the other hand, it is desirable to exhibit high activity in solid rocket propellants to obtain high energy release rate and...

Due to the extremely strong surface activity of nano TiO2, it is easy to form large-sized agglomerates, which affects the practical application. Therefore, it can be modified from the aspects of improving the photocatalytic degradation efficiency of TiO2, changing the dielectric constant and surface activity of TiO2. There are two ways of combining surfactants with TiO2: one is physical adsorption...

The formation of a stable dispersion system, in addition to using electrostatic repulsion, that is, the negative charges adsorbed on the surface of the particles repel each other, to prevent the adsorption/aggregation between particles and finally form large particles and stratify/settlement, but also use. The theory of the steric hindrance effect, whereby particles that have adsorbed negative cha...
