(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 ... -
Sulfuric acid attack on ordinary Portland cement and geopolymer material
(Institute for Scientific Information (ISI), 2013-09)The resistance of ordinary Portland cement binder towards acid had been widely discussed by researchers. The deterioration effect of this binder may cost high repair expense and rehabilitation. Geopolymer material is a new ... -
Surface modification via wet chemical etching of single-crystalline silicon for photovoltaic application
(Elsevier Ltd., 2013-11)The potential of solar cells have not been fully tapped due to the lack of energy conversion efficiency. There are three important mechanisms in producing high efficiency cells to harvest solar energy; reduction of light ... -
Surface morphology and corrosion behavior of electrolytic coatings in different aqueous solutions
(Trans Tech Publications, 2014)ZrO₃/AI₂O₃, AI₂O₃/Y₂O₃, ZrO₂/Y₂O₃ coatings were applied on SS440C steel substrates via an electrolytic double layer coating process. The effect of these different ceramic aquecous solutions on the surface morphology and ... -
Surfactant-free synthesis of copper particles for electrically conductive adhesive applications
(TMS, 2012-09)In this study, a simple one-step microwave-assisted method was developed to synthesize Cu and Cu-Ag particles for application in electrically conductive adhesive (ECA). The particle size of the obtained Cu particles was ... -
Synthesis and characterization of electroless copper coated SiC particles
(Trans Tech Publications, 2013)Silicon carbide reinforced copper matrix (Cu-SiCp) composites fabricated via the conventional powder metallurgy methods have inferior thermophysical properties due to the weak bonding between the copper matrix and the SiCp ... -
