Hello, dear researchers. I'd like ask about your opinion about this UV graph?

More Reham Hamida's questions See All

Hello, how can i expect that UV graph of nanoparticles such as SNPs is accurate and represent good results?

actually my question about the shape of the UV curve when i read articles , i saw different UV graphs some are sharp while other board, although the two values after measure the highest point in...
