Characterisation, analysis and optical properties of nanostructure ZnO using the sol-gel method
Muhammad, Kashif; Yarub, Al-Douri, Assoc. Prof. Dr.; Uda, Hashim, Prof. Dr.; Md. Eaqub, Ali; Syed Muhammad Usman, Ali; Willander, Magnus, Prof (Institution of Engineering and Technology (IET), 2012-02)Nanostructure ZnO was grown on thin aluminium layer, deposited on silicon substrate using the sol-gel method. The surface morphologies of nanostructure ZnO at different precursor concentrations were studied using scanning ... -
Functionalised zinc oxide nanotube arrays as electrochemical sensors for the selective determination of glucose
Syed Muhammad Usman, Ali; Mohammad, Kasfhi; Zafar Hussain, Ibupoto; Muhammad, Fakhar-e-Alam; Uda, Hashim, Prof. Dr.; Magnus, Willander (The Institution of Engineering and Technology, 2011-08)In the present study, highly oriented single-crystal zinc oxide nanotube (ZnO-NT) arrays were prepared by a trimming of ZnO nanorods along the c-axis on the gold-coated glass substrate having a diameter of 100-200nm and a ... -
Sensitivity of A-549 human lung cancer cells to nanoporous zinc oxide conjugated with Photofrin
Muhammad, Fakhar-E-Alam; Syed Muhammad Usman, Ali; Zafar Hussain, Ibupoto; Kimleang, Khun; Muhammad, Atif; Mohammad, Kashif; Loong, Foo Kai; Uda, Hashim, Prof. Dr.; Willander, Magnus (Springer-Verlag London Ltd., 2012-05)In the present study, we demonstrated the use of nanoporous zinc oxide (ZnO NPs) in photodynamic therapy. The ZnO NPs structure possesses a high surface to volume ratio due to its porosity and ZnO NPs can be used as an ... -
Structural and impedance spectroscopy study of Al-doped ZnO nanorods grown by sol-gel method
Muhammad, Kashif; Uda, Hashim, Prof. Dr.; Md. Eaqub, Ali; Ala'eddin Ahmad Jaber, Saif, Dr.; Syed Muhammad Usman, Ali; Willander, Magnus, Prof (Emerald Group Publishing Limited, 2012)Purpose – The purpose of this paper is to investigate the electrical transport mechanism of the Al-doped ZnO nanorods at different temperatures by employing impedance spectroscopy. Design/methodology/approach – Al-doped ...
