    • Sintering effects on mechanical properties of Co-HA composite prepared by modified electroless deposition. 

      Mohd Zaheruddin, Kasmuin; Sri Asliza, Md Amin; Azmi, Rahmat, Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Khairel Rafezi, Ahmad, Dr. (Trans Tech Publications, 2014)
      Co-HA composite produced using electroless deposition without conventional sensitization and activation treatment was studied with varying sintering temperature (1100°C, 1200°C and 1250°C). The particles size, bulk density, ...
    • A study of comminution-liberation and floatability of Copper from printed circuit boards (PCBs) scrap 

      Aimi Noorliyana, Hashim; Mohd Zaheruddin, Kasmuin; Md Fazlul, Bari; Sri Asliza, Md Amin; Kamarudin, Hussin (Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
      Printed circuit boards (PCBs) were collected from obsolete or defective computers that are the largest source of the kind of waste. PCBs are composed of different materials such as polymers, ceramics and metals. The studies ...
    • A study of liberation and separation process of metals from printed circuit boards (PCBS) scraps 

      Aimi Noorliyana, Hashim; Mohd Zaheruddin, Kasmuin; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Trans Tech Publications, 2013-12)
      Since the metallic elements are covered with or encapsulated by various plastic or ceramic materials on printed circuit boards (PCBs), a pre-treatment process allowing their liberation and separation is first needed in ...
    • A study of Mg effects on PM Al - Mg alloys 

      Kamrosni, Abdul Razak; Mohd Nazree, Derman, Dr.; Normah, Che Man; Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      This research has been done to study the effects of Magnesium content in PM Al-Mg alloys. The research involved is fabrication of aluminum alloys with various weight percent of Magnesium powder via powder metallurgy routes. ...
    • A study on floatability of copper using Modified Hallimond Tube 

      Aimi Noorliyana, H.; Mohd Zaheruddin, Kasmuin; Md. Fazlul, Bari; Sri Asliza, Md Amin; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Universiti Malaysia Pahang (UMP), 2009-06-20)
      The Floatability of copper on the Modified Hallimond tube depend on lots of parameters such as dosage and types of collector, frother, air flow rate, flotation time, and pH value. All of this parameters give different ...
    • 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 ...
    • Study the properties of dense Hydroxyapatite - Extract from cow bone 

      Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Shahrizal, H.; Nurul Fazliana, Z. A (Malaysian Institute for Nuclear Technology Research, 2009)
      In this study, natural HA were extrated from clean cow bone by treatment with NaOH and heating at high temperature before ground into fine powder. The HA powder were than mixed together with binder for several hours. Dense ...
