Comparison of dynamic mechanical properties of non-superheated and superheated A357 alloys
(Slovak Academy of Sciences, 2010-03-01)
The influence of superheat treatment on the microstructure and dynamic mechanical properties
of A357 alloys has been investigated. The study of microstructure was performed by optical
microscope. Dynamic mechanical ...
Effects of Acetic Anhydride on the properties of Polypropylene(PP)/Recycled Acrylonitrile Butadiene(NBRr)/Rice Husk Powder(RHP) composites
(Taylor and Francis Ltd., 2012-11)
PP/NBRr/RHP composites were prepared by incorporation of rice husk powder at different loadings into PP/NBRr matrix with an internal mixer at 180°C for 9 min and 50 rpm rotor speed. The effects of rice husk powder filler ...
Preliminary study on concrete with Polystrene waste coarse aggregate
(2007)
Polystrene wastes are becoming a major environment concern; due to its large production quantities and its non-biodegrable nature. Provided that the high molecular-weight material can be broken down into useful low ...
Synthesis of sol-gel silica chemically bonded with cyanex 272 for the removal of Cu(II), Ni(II), and Zn(II)
(Springer Netherlands, 2009-05)
This article reported on the synthesis of SSCBB, a new solid-phase, sol-gel silica chemically bonded with [bis (2,4,4-trimethylpentyl) phosphinate], (BTMPP, anion of Cyanex 272) prepared with a sol-gel method, and its ...
‘Batu Reput’ used as raw material in fertilizer production
(Malaysian Institute for Nuclear Technology Research (MINT), Xapp Malaysia-MNS & Universiti Kebangsaan Malaysia (UKM), 2006-11-29)
‘Batu Reput’ is primary sediment mineral and abundantly found in Perlis. Perlis is one of the major producers of ‘Batu Reput’ in

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 ...
Chemical & Mineralogical Properties of Fly Ash
(Malaysian Nuclear Society, 2007)
Fly ash is the finely divided mineral residue resulting from the combustion of coal in electric generating plants. Fly ash consists of inorganic, incombustible matter present in the coal that has been fused during combustion ...
Failure analysis and characterization of Ferrous-Base alloy exposed in seawater environment
(Universiti Kebangsaan Malaysia (UKM), 2008-12-03)
Ferrous-base alloy are well-suited and widely used for a broad range of engineering
applications such as structural steelwork, pipelines, vessels in refineries, thermal power plant establishment, etc. not for their corrosion ...
Stability of Perlis dolomite under various heating condition
(Universiti Teknologi Mara (UiTM), 2006-12-08)
Dolomite is a yellowish colored rock that can be found abundantly in Perlis. The rock has been used traditionally either to cover the rural road before it is tarred or to normalize the soil before any crops is planted. ...
