    • PC1D analysis of thin-film crystalline SixGe1-x/Si solar cells 

      Adnan K Shafeeque, Ali; Ayu Wazira, Azhari; Samir, Ahmad; Kamaruzzaman, Sopian; Saleem Hussain, Zaidi (Institute of Electrical and Electronics Engineers Inc., 2014-10-15)
      Inability to achieve complete optical absorption in thin-film crystalline Si (TF c-Si) solar cells fundamentally limits efficiency. Therefore, materials with high absorption across the entire solar spectrum are highly ...

    • The potential of satellite images in soil compaction study for implementation of precision agriculture 

      Norasmanizan, Abdullah; Ayu Wazira, Azhari; Mahmad Nor, Jaafar, Assoc. Prof. Dr.; Mohd Sabri, Hussin; Salwa, Mohd Zaini Makhtar (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      This paper observed the potential of satellite imagery in soil compaction study based on the spectral analysis. The aim of this study is to produce the potential of soil compaction map through the measuring compactness ...

    • Recent graphene oxide/TiO₂ thin film based on self-cleaning application 

      A. Azani; Dewi Suriyani, Che Halin; Kamrosni, Abdul Razak; Mohd Mustafa Al Bakri, Abdullah; Mohd Arif Anuar, Mohd Salleh; Norsuria, Mahmed; Muhammad Mahyiddin, Ramli; Ayu Wazira, Azhari; Chobpattana, V. (IOP Publishing Ltd, 2019-08)
      Graphene oxide/TiO₂ (GO/TiO₂) thin films works as self-cleaning device have been developed in various method onto selected substrates. It was noticeable that graphene oxide is the best form in the group of graphene family. ...

    • Recycling potential of waste materials as fire resistance material 

      Ayu Wazira, Azhari; Abdul Haqi, Ibrahim; Mahyun, Ab Wahab; Salwa, Mohd Zaini Makhtar; Azmil, Mohd Aris (Universiti Teknologi Malaysia (UTM), 2009-06-02)
