| 1 | Comment from Dr. Noorshida Binti Mohd Ali | Instead of surface potential results, is there any other analyses methods that will be done in future to support or prove that the Pb2+ ion trapped into the host C-DHC4 exactly at the lower rim part. |
| 2 | Comment from Prof. Madya Ts. Dr. Che Nor Aiza Jaafar | Two type of clix[4[arenes were used in this study i.e C-DHC4 and N-DHC4 with difference functional groups. However the SEM results reveals that the structure of N-DHC4 is irregular dan not well arrange as compared to C-DHC4. My question is how to confirm the lower performance of N-DHC4 is actually due to different functional groups NOT because of imperfect structure. |
