The reduction of Au+ particles to Au0 NPs can be discussed by the reduction potential (E0) of redox system elements. my question is, how will you calculate the reduction potential for Au+/Au0 and so on?
I would like to order JASCO V-770 UV-Vis-NIR spectrophotometer, my question is, can we use this instrument for studding absorption spectra or it has capability only for transmittance and...
