Fabrication of titanium carbide reinforced copper matrix composite by in-situ processing
(Universiti Malaysia Perlis, 2010-06-09)
Composite materials with copper matrix and ceramic particle reinforcements provide an alternative material for scope for producing relatively high thermal conductivity, electrical conductivity and hardness properties. Most ...
Stabilization of magnetite nano iron oxide with a series of novel surfactants
(Universiti Malaysia Perlis, 2010-06-09)
Oleic acid which is one of the palm oil derivatives is known to effectively stabilize dispersions of nanomagnetite in nonpolar solvent. Stabilization occurs because the carboxylic acid group covalently reacts with the ...
Mineralogical component of palm oil fuel ash with or without unburned carbon
(Universiti Malaysia Perlis, 2010-06-09)
The purpose of this paper is to investigate the mineralogical components of palm oil fuel ash (POFA) with or without unburned carbon by using semi-quantitative X-ray diffraction (XRD). Original POFA taken from palm oil ...
Preliminary development of radioscopy detector for specific industrial radiography inspection
(Universiti Malaysia Perlis, 2010-06-09)
A digital X-ray detector based on fluoroscopy concept was designed and fabricated. The detector consists of digital monochrome video camera, first surface mirror and fluorescence screen. Preliminary quantitative tests of ...
Hydrogenolysis of glycerol to propanediols over nano-Ru/C catalyst with ionic liquid addition
(Universiti Malaysia Perlis, 2010-06-09)
Supported ruthenium catalyst on nano-activated carbon (2% Ru/C) and titania (2%Ru/TiO2) were prepared by wet impregnation technique with addition of ionic liquid and without ionic liquid (1-decyl-3-methylimidazolium and ...
Formation of TiC-reinforced iron based composite through carbothermal reduction of hematite and anatase
(Universiti Malaysia Perlis, 2010-06-09)
In this research carbothermal reduction of mechanical activated hematite (Fe2O3), anatase (TiO2) and graphite (C) was investigated. The mixtures of raw materials with composition of Fe-20vol%TiC were mechanically activated ...
La-Doped CaCu3Ti4O12 ceramics synthesized under argon environment
(Universiti Malaysia Perlis, 2010-06-09)
The properties of undoped and La-doped CaCu3Ti4O12 (CCTO) ceramics synthesized via solid state reaction under argon environment had been studied. La-doped CCTOs found to have higher dielectric constant than undoped CCTO. ...
New silica supported HClO4 as an efficient catalysts for the estolide synthesis from oleic acid
(Universiti Malaysia Perlis, 2010-06-09)
The synthesis of estolides via condensation reaction of oleic acid were investigated using heterogenous and homogenous catalysts. The condensation reaction usually carried out by using of various acids catalysts, such as ...
Selective oxidation of glycerol over titania supported AuPd bimetallic catalysts
(Universiti Malaysia Perlis, 2010-06-09)
Oxidation of glycerol to form various types of important short chain oxygenated derivatives became an important reaction to support biodiesel industries. In this study, a series of AuPd nanoparticles at different metal ...
Effects of the polyvinyl alcohol (PVA) on the synthesis of alumina fibers through electrospinning technique
(Universiti Malaysia Perlis, 2010-06-09)
Ceramic fiber products especially
alumina has good properties such as high
modulus and strength that were resistant
toward the attacks of molten metals and nonoxide
materials up to 1000°C and also have
low thermal ...
