Simultaneous extraction and separation of Cu(II), Zn(II), Fe(III) and Ni(II) by polystyrene microcapsules coated with Cyanex 272
(Elsevier B.V, 2009-02)
The preparation of polystyrene microcapsules coated with Cyanex 272 (MC-Xs) have been investigated and simultaneous extraction and separation behavior of Cu(II), Zn(II), Fe(III) and Ni(II) in both batch and packed column ...
Effect of Compatibilizer on Mechanical Properties and Morphology of Clay Filled Low Density Polyethylene (LDPE) Composites
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
The main purpose of incorporating fillers, such as clay into composites of polyolefin is to decrease costs and change the properties. Structural differences between both components give rise to the formation of large filler ...
Preliminary Microstructure and Hardness Studies of A356/Stainless Steel Composite via Gravity Die Casting Technique
(Universiti Malaysia Perlis (UniMAP), 2007-06-09)
The microstructure and hardness of A356/stainless steel composite via gravity die casting technique were evaluated. Both nearly completed bonding and incomplete bonding was seen at the stainless steel wire-
A356 matrix ...
Effects of dynamic vulcanization and acrylic acid on properties of recycled poly(vinyl chloride)/acrylonitrile butadiene rubber (PVCr/NBR) blends
(Taylor & Francis, 2006)
Effects of dynamic vulcanization and acrylic acid (AAc) on processability, mechanical properties, swelling behavior, morphology, and thermal stability of recycled poly(vinyl chloride)/acrylonitrile butadiene rubber (PVCr/NBR) ...
The effects of autocatalyst copper coating of SiCp on the microstructure of CuSiCp composites
(Universiti Malaysia Perlis, 2009-12-01)
In this paper, the autocatalyst copper coating (ACC) of silicon carbide particle
(SiCp) was performed after a sequence of surface treatment, sensitization and
surface activation processes. The ACC process was operated ...
Crystal structure of single phase and low sintering temperature of α-cordierite synthesized from talc and kaolin
(Elsevier B.V., 2009-08)
Cordierite body with the formulation of 2.8MgO·1.5Al2O3·5SiO2 was prepared from talc and kaolin as the basic raw materials. Following glass crystallization technique the glass powder was successfully heat treated at 900 ...
Lattice Imperfections in Intermetallic Ti-Al alloys: an X-Ray Diffraction study of the microstructure by the Rietveld method
(Universiti Malaysia Perlis, 2008-03)
Microstructure in intermetallic Ti-Al alloys with compositions of Al= 45, 50, 55, and 60%
in the homogenized bulk states has been extensively studied using Rietveld whole X-ray profile fitting technique, adopting the ...
The effect of compatibilizer on tensile properties, swelling behaviour and morphology of Calcium Carbonate filled Polypropylene/Ethylene Propylene Diene Terpolymer composites
(Universiti Kuala Lumpur (UniKL), 2007-11-27)
Calcium carbonate (CaCO3) was used as filler in the polypropylene (PP)/ ethylene propylene diene terpolymer (EPDM) composites in order to decrease cost and change the properties. The composites were prepared by using a ...
Selective leaching for the recovery of Copper from PCB
(Universiti Malaysia Perlis, 2009-12-01)
This paper reported on the leaching behavior of printed circuit board (PCB) using a new leaching agent of ammonia-ammonium persulfate, to recover copper. Cu and Zn leaching were found to be fast and reached equilibrium in ...
The effects of dynamic vulcanization and compatibilizer on properties of paper sludge-filled polypropylene/ethylene propylene diene terpolymer composites
(Wiley Periodicals, 2007)
The effects of dynamic vulcanization (DV) and dynamic vulcanization plus compatibilizer (DVC) of paper sludge (PS) filled polypropylene/ethylene propylene diene terpolymer (PP/EPDM) composites on torque development, ...
