In this study, firstly electrochemical etching of the (n and p) type silicon wafers are used to prepare of (n and p) type of porous silicon with a current density of 10 mA.cm-2 at 10 minutes. The structural and morphological ...

Nanoparticles of Mn1-xZnxFe2O4 have been prepared by co-precipitation method and followed by heat treatment in hydrothermal autoclave reactor; where x varied from 0 to 0.5, with amount of change 0.1 in every experiment. XRD ...
