The specific surface area is the surface area (㎡/g) of the substance per unit mass. It is one of the most important physical properties of ultra-fine powder materials, especially nano-powder materials. It is used to evaluate their activity, adsorption, catalysis and other properties. important physical properties. Therefore, in the research, manufacture and application of various ultrafine powder ...

In building energy conservation, the light transmission and heat insulation of glass is a very critical issue. In buildings with transparent ceilings and large-area exterior windows, the thermal radiation of sunlight will lead to an increase in the energy consumption of air conditioners, resulting in a large energy waste. In order to improve this phenomenon, nano-scale antimony doped tin oxide ATO...

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 summer, the sun is strong, and the sunlight enters the room through the glass, causing the temperature in the car to rise sharply, which seriously affects the comfort of living and vehicle riding. Among them, the energy in the infrared band accounts for the largest proportion, and it is also the main source of energy for the temperature increase in the place where the sunlight is irradiated. By...

Glass thermal insulation coating is a kind of coating prepared by one or more nano powder materials. The nano materials used have special optical properties, that is, they have high blocking rate in the infrared region and ultraviolet region. , has a high transmittance in the visible region. Using the transparent and heat-insulating properties of the material, it is mixed with an environmentally f...

Infrared light has an obvious thermal effect, which can easily lead to an increase in ambient temperature. Ordinary architectural glass has no thermal insulation effect, and can only be achieved by means of filming. Therefore, architectural glass, car film, outdoor facilities and other surfaces need to use thermal insulation materials to achieve the effect of thermal insulation and energy saving. ...
