By using the average band-gap model,the chemical bond properties of (La1-xMx)2CuO4(M=Ba,Sr) were calculated.The calculated covalencies for Cu-O and La-O bond in
Ni-Al2O3 cermet supported tubular SOFC was fabricated by thermal spraying. Flame-sprayed Al2O3-Ni cermet coating plays dual roles of a support tube and an anode
The quality of dark output images from the CMOS (complementary metal oxide semiconductor) black and white (B&W) digital image sensors captured before and after
