    • Characterization of calcium phosphate bioceramic from Paphia undulata shells 

      Nur Farahiyah, Mohammad; Muhammad Hariz, Muhammed; Zulkarnay, Zakaria; Azian Azamimi, Abdullah; Intan Shafinaz, Mohammad (Institute of Electrical and Electronics Engineers (IEEE), 2012-02-27)
      This study aim to synthesize bioceramic from Paphia undulata shell by using dry technique in order to proposed new bioceramic for human bone repair application. The clam shells obtained from the fisherman of Kuala ...

    • Characterizations of biocompatible and bioactive hydroxyapatite particles 

      Midhat Nabil, Ahmad Salimi, Dr.; Anuar, A. (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      The most common gene vectors used are virus based (viral gene vectors). These possess high immunological risk, so a non-viral gene vector maybe preferable. Nanocrystalline hydroxyapatite, HAp [Ca10(PO4)6(OH)2] is an example ...

    • The effect of additives to the densification of natural hydroxyapatite 

      Sri Asliza, M. A; Shahrizal, H; Zaheruddin, K; Azida, Azmi (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      The effect of different additives to the microstructure and phase properties of compact natural hydroxyapatite was studied. Compact HA was fabricated from HA powder obtained from bovine bones via calcinations and grinding ...

    • Fabrication of functionally graded materials from Hydroxyapatite and F75 Cobalt alloy 

      Noorazimah, A.; Nur Hidayah, Ahmad Zaidi; Shamsul Baharin, Jamaludin, Prof. Dr. (Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)
      Functionally graded materials were fabricated using Hydroxyapatite (HAP) and F75 cobalt alloy. Both of these two materials are important in creating biomaterials that is compatible to the human tissue and at the ...

    • Improvement of dense hydroxyapatite from natural bone with TiO2 powder 

      Sri Asliza, Mat Amin; Mohd Zaheruddin, Kasmuin; Siti Sarah, Ibrahim (Universiti Putra Malaysia (UPM)Fakulti Perubatan dan Sains Kesihatan, 2007-12-10)
      In this study HA powder were obtained from natural bone. Natural HA were extrated from clean cow bone by heat treated at temperature 800c before ground into fine powder. The HA powder were mixed together with different ...

    • Preliminary study on the stannous ions removal from aqueous solutions by hydroxyapatite 

      Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Kamrosni, Abdul Razak (Universiti Malaysia Perlis (UniMAP), 2012-07-18)
      The effect of stirring times and pH of solutions on the potential of HA in removing Sn ions have been investigated. The results shown that HA powder have tendency to remove a number of Sn ions by adsorption mechanisms. The ...

    • Preparation and characterization of hydroxyapatite powder from biological natural bone 

      Sri Asliza, Md Amin; Shahrizal, Md Hussein; Zaheruddin, Kasmuin; Azida, Azmi; Siti Sarah, Ibrahim (Universiti Tun Hussein Onn Malaysia, 2008-11-24)
      Hydroxyapatite (HA) is widely used in medical fields especially as a bone substitute, due to its good biocompatibility, bioactivity, high osteoconductive and nontoxic. The production of synthetic HA needs very complicated ...

    • Preparation and characterization of natural Hydroxyapatite from bovine bone 

      Shahrizal, M. H.; Sri Asliza, Md Amin; Mohd Nazree, Derman; Mohd Zaheruddin, Kasmuin (Universiti Sains Malaysia (USM), 2008-06-18)
      The purpose of this study was to prepare and characterize Hydroxyapatite from natural source. Hydroxyapatite fine powder with average size particle of 10.324 um had been prepared by heating bovine bone at temperature 800°C ...

    • Study the effect of TIO2 and soaking time to the natural hydroxyapatite properties 

      Shahrizal, M. H.; Sri Asliza, Md Amin; Mohd Nazree, Derman; Mohd Zaheruddin, Kasmuin (Universiti Sains Malaysia (USM), 2006-05-24)
      Natural hydroxyapatite has potential to be used as implant material in biomedical applications. In this study natural HA were obtained from bovine bone by heated and ground into desired size. Dense natural HA were fabricated ...

    • Synthesis and characterisation of hydrogel based composites for bone regeneration 

      Killion, John; Gonzalez, Nelly; Geever, Luke; Devine, Declan; Kennedy, James; Higginbotham, Clement L. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      The current gold standard treatment for bone defects are biological grafts. Due to the inherent disadvantages for these biological grafts, a new synthetic alternative are being sought. Tissue ...
