Is it possible for Cu spectra to mask the effects of Cu2O and CuO in UV-Vis?

My XRD results yielded points at CuO, Cu2O and Cu. However, my UV-Vis spectra only has one peak at around 580 nm which may or may not correspond to Cu since CuO also has a broad range. Is it...

What polymer can I use if I want to electrospin metal nanoparticles?

I want to electrospin metal nanoparticles. However, I am unsure if it is possible because my metal nanoparticles are in a colloidal suspension. But, is it possible? Thanks!
