Hello guys, in advance, let me appreciate all answers. I am looking for some required data fro microscopic analysis for transport properties. first, I need to know pore distribution and porosity, by SEM image and imageJ software, I am trying to find them. but the average pore diameter found by image J is so different compared what the manufacturer presents as the average pore diameter and porosity. Maybe I am not right to do steps. Please let me know how to do it?
