Need more info.. but looks like NiCoS platelets with poorly dispersed CNT.. holey because the sheets have pores... if its in-plane pores then interesting result

Muhammad Sajjad

Hello Sir Sridhar Vadahanambi

attach isthe TEM of the same sample can you explain me a little more in details whichmorphology it refmlects from SEM and from TEM it looks like clusters whta do you think about that?

Yusuf Koçak

in the sample, you can take a closer view of the crystal structure or you can point analyze the TEM EDS.
