Extraction and separation of Cu(II), Ni(II) and Zn(II) by sol-gel silica immobilized with Cyanex 272
(Elsevier B.V., 2009-03)
The extraction and separation of Cu(II), Ni(II) and Zn(II) from aqueous sulfate-acetate solution were carried out using solid phase sol-gel silica containing immobilized Cyanex 272 {bis(2,4,4-trimethylpentyl)phosphinic ...
Nitridation of Al-Mg-Si alloys through dynamic heating
(Universiti Kebangsaan Malaysia, 2007-12)
Nitridation behaviour of Al-Mg-Si alloys as studied as a function of temperature by means of thermogravimetry method. A reactive gas, N2-4%H2 at a rate of 10 ml/min was purged into the thermogravimetry analyser chamber. ...
Landfill odour detection using Quartz Crystal Microbalance (QCM)
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005)
Odour is considered as the main environmental pollution agent in Malaysia. Eventhough the standard permitted level has not been set for Malaysia as for air and water, but still the odour has been connsidered as one of the ...
Oxidation behavior of SAE-1053 alloy in presence of seawater
(INSInet Publication, 2009-01)
The oxidation behavior of steel SAE-1053 alloy were investigated in presence of seawater at atmospheric condition. The rate of corrosion was varied with the water movements and the aeration. The scale morphologies were ...
Extraction mechanism of Gd3+ by BTMPPA
(Elsevier, 2006)
The extraction behavior of Gd(III) from acidic nitrate-acetato medium by bis(2,4,4-trimethylpentyl)phosphinic acid (BTMPPA, H2A2) in toluene either alone or in combination with trioctylphospine oxide (TOPO, B) has been ...
Oxidation behaviour of IN-738 LC Superalloys in the presence of Ionic Salts at 1173 K
(Portuguese Electrochemical Society, 2003)
Oxidation of the alloy having nominal composition Ni-16Cr-8.5Co(wt.%) was studied
in the presence of KCl and K2CO3 at 1173 K in air. Chemical composition of oxide
scales and scale morphologies were determined by means ...
Corrosion behaviour of aluminium alloy treated with vegetable and mineral oil lubricationts in NaCI medium
(Oriental Science Publishing Co, 2004-07-30)
The inhibitive effect of vegetable oil and mineral oil on the corrosion of aluminum alloy has been studied at 60°C in 8%(w/v) and 10%(w/v) NaCI solution by mass change method. The effect of NaCI concentration and time of ...
Dye removal from aqueos solution by using adsorption on treated sugarcane bagasse
(Science Publications, 2005)
The effect of heat treatment on the open circuit potential of magnesium sacrificial anode
(University of Malaya, 2009)
Magnesium sacrificial anode that possess high value of open circuit potential, Eoc is needed as it can protect larger area of underground metal structure in cathodic protection. Solution treatment was applied on magnesium ...
Aluminium parts from scrap using new technique
(Journal of Ultra Scientist of Physical, 2000)
A new method for making aluminium parts using scrap under Asian condition has been suggested. The new technique is known as Powder Metallurgy (P/M) and is the technology of future. The process is economic, clean, requires ...
