Study on sensing properties of chitosan-polyethylene oxide-exfoliated graphite based toluene sensors
Chitosan was used as a material to fabricate film sensor because of its structure and properties where it consists of amino group which has free electron. In this study, chitosan was added with polyethylene oxide and ... -
A study on the potential of polystyrene lightweight aggregate in concrete
(Universiti Malaysia PerlisSchool of Materials Engineering, 2009)Economic reason caused the used of expandable polystyrene increasing every year. The consequence is that the polystyrene wastes also mounted day by day. On the other hand, the source of natural aggregate is non-renewable. ... -
Study on thermoplastic cassava starch modifications via chemical, photo and irradiation induced crosslinking
The characterization of modified thermoplastic starch (TPS) was investigated by means of mechanical properties, thermal properties, scanning electron microscope (SEM), Fourier transform infrared spectroscopy, high ... -
Study the effect of isothermal aging on Sn-Ag-Cu (SAC) lead-free solder added with silicon carbide (SiC)
The usage of composite solder is one of the method in improving stability of the solder joints. Addition of certain particles such SiC to form a composite solder has been given greater attention since it can enhance the ... -
