The final step is to go home to buy pig's blood or cow blood to eat, these two things to the dust have a strong absorption edge, adhesion can greatly reduce the dust in the lungs.
The optical transmittance of al doped AZO is as high as 85% in the visible region, the UV absorption edge is blue shifted greatly with increasing al doping concentration.
Blue shifts of absorption edges of the nanocrystallines were observed in both the ultra-filtrated acidic and alkaline sols.
