The third generation of semiconductors, represented by gallium nitride (GaN) and silicon carbide (SiC), have been rapidly developed due to their excellent properties. However, how to accurately mea...
The basic process of SiC crystal growth is divided into sublimation and decomposition of raw materials at high temperature, transportation of gas phase substances under the action of temperature gr...
Silicon is an atomic crystal, whose atoms are connected to each other by covalent bonds, forming a spatial network structure. In this structure, the covalent bonds between atoms are very directiona...
A fuel cell stack will not operate stand-alone, but needs to be integrated into a fuel cell system. In the fuel cell system different auxiliary components such as compressors, pumps, sensors, valve...
The second authorization bill defines a method for calculating life-cycle greenhouse gas emissions from renewable fuels from non-biological sources. The approach takes into account greenhouse gas ...
First, the principle of mixing
By stirring the blades and the revolving frame to rotate each other, the mechanical suspension is generated and maintained, and the mass transfer between the liquid a...
