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...

Please, i want to learn about UV graph ?

the blue circle in uv graph can consider as the head of graph and can i take this points the value of the wavelength of nanoparticles ? in the photo with number 1 this graph indicates that there...

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

first image for SNPs synthesized by certain plant, while second image is the UV of plant extract without silver nitrate i think the wavelength of SNPs start from 300 to 450 nm? thank you

Hello, dear researchers. I'd like to ask about the calculation of the mean of nanoparticles size ?

How can i calculate the mean of nanoparticle size (large and small)? in respect to that i have different size of NPs in the same TEM micrograh. other question, do all TEM micro-graphs need to set...

What happen if the bulk material in the biological synthesis is a nano-material ?

Actually, I think in this idea but I don't Know if it is correct or not what happen if I start the biological synthesis process using nano-material as a bulk material ? in this case, if I use...
