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 ... -
A potentiometric indirect uric acid sensor based on ZnO nanoflakes and immobilized uricase
Syed Muhammad, Usman Ali, Dr.; Zafar Hussain, Ibupoto; Muhammad, Kashif; Uda, Hashim, Prof. Dr.; Willander, Magnus (MDPI, 2012-03)In the present work zinc oxide nanoflakes (ZnO-NF) structures with a wall thickness around 50 to 100 nm were synthesized on a gold coated glass substrate using a low temperature hydrothermal method. The enzyme uricase was ... -
