Development of dense Hydroxyapatite from natural and synthetic sources
(University Malaysia Perlis (UniMAP), 2007-06-09) -
Development of dense hydroxyapatite-ni by modified electroless deposition technique.
(Trans Tech Publications, 2014)Ni deposited on HA powder was prepared by electroless plating process without sensitization and activation treatment. The deposited powder obtained was characterized by energy dispersive spectroscopy (EDX) and x-ray ... -
Effect of different nickel content on the mechanical properties of hydroxyapatite-ni composites from coated powders
(Trans Tech Publications, 2014)HA-Ni composites were fabricated by uniaxial pressing from coated powders, in which HA particles were successfully coated with nickel precursor by the electroless deposition method. The compacted powders sintered at ... -
Fabrication of calcium phosphate coating on pure magnesium substrate via simple chemical conversion coating: surface properties and corrosion performance evaluations
(Elsevier, 2018)The main objective of the current work was to fabricate calcium phosphate (CaP) coating on 99.9% purity magnesium, Mg substrate through simple chemical conversion method and evaluated the surface properties and corrosion ... -
Improvement of dense hydroxyapatite from natural bone with TiO2 powder
(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 ... -
Investigate the liberation of copper from waste Printed Circuit Boards (PCBs)
(Universiti Malaysia PerlisSchool of Materials Engineering & School of Environmental Engineering, 2010-06-09)Nowadays the waste PCBs increasing sharply proportionally the number of personal computers which is 5.7 million in 2005 and the predict amounts, it will be increase to 11.5 Million in 2010 (Unit Perancangan Ekonomi, ... -
Preliminary study on the stannous ions removal from aqueous solutions by hydroxyapatite
(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 Co-HA powder using modified electroless method
(Trans Tech Publications, 2014)C0-HA composite produced by simple electroless deposition method was studied. From the particle size analysis by Malvern particles analyzer its shows that 19% increment in average of the particle size powder increase after ... -
Preparation and characterization of natural Hydroxyapatite from bovine bone
(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 ... -
Sintering effects on mechanical properties of Co-HA composite prepared by modified electroless deposition.
(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
(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
(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 ... -
