Divinah Manoharan replied to Paul S's discussion Zero dimension????
"Zero dim is nothing but quantum dot. The size will be approximately <10nm. Comparable to its bohr atomic radius the particle size will vary. So u cant tell that all particles less than 10 nm are quantum dots.It will vary from material to material. I…"

"I need electrochemical impedence ie, arrhenius plots and complex impedance plots for materials prepared for application in fuel cell at temperature from 400 to 800 degree C. It would be also good if i get I-V and I-P characteristics."
