Preparation and characterization of silica aerogel immobilized with cyanex 301 for extraction of Zn(II)
(Trans Tech Publications, 2013)
A new solid phase extractant silica aerogel immobilized with Cyanex 301 {bis(2,4,4- trimethylpentyl) dithiophosphinic acid} (SAWC) was prepared via a sol- gel method and investigated for the extraction of Zn(II) from aqueous ...
Kinetic and thermodynamic studies on adsorption of copper ions onto pomelo peel (citrus grandis)
(Trans Tech Publications, 2013)
The ability of pomelo peel (PP) as natural adsorbent to remove Cu (II) ions from aqueous solution was investigated. The influence of solution pH, contact time and temperature were evaluated. Cu (II) removal increased as ...

constructions. This study develop new products made of by biomass ash from industry waste for the internal partitions panel. Modifying the internal partition panel of wall with addition of biomass ash (EFB) and clay soils ...
Mechanical properties of dissimilar welds between stainless steel and mild steel
(Trans Tech Publications, 2013)
Joining of stainless steel type 304 to mild steel was carried out using a gas tungsten arc welding (GTAW). Samples were welded using stainless steel welding electrode: (AWS: E308l-16) and mild steel welding electrode: (AWS: ...
Effect of spot welding current and cycles on the mechanical properties of welded galvanized steel sheets
(Trans Tech Publications, 2013)
Studies on the effects of welding current and cycles were carried on the galvanized steel sheets using spot welding. The welding currents used were 3 kA, 5 kA 6 kA and the welding cycles were 4, 6 and 8. Tensile shear and ...
Preparation of colossal magnetoresistance ploycrystalline via sol-gel technique: a short review
(Trans Tech Publications, 2013)
This paper presents a short review of research work on the development of synthesizing the colossal magnetoresistance materials through sol-gel method. Although there are a lot number of methods available, sol-gel method ...
Effect of roughness of hypo-and hyper-eutectic Al-Si piston alloy on wear characteristics under lubrication
(Malaysian Technical Universities Network (MTUN), 2012-11-20)
The tribological behavior of tow AlSi alloys under the influence of surface roughness average was investigated for the present study. The silicon content of these alloys ranged 10 and 16-wt% Si, and includes hypoeutectic ...
Evaluate the effects of various surface roughness on the tribological characteristics under dry and lubricated conditions for Al-Si alloy
(Scientific Research Publishing Inc. All rights reserved., 2012-07)
The effect of surface roughness average of hypereutectic aluminum silicon alloys (with 16 wt% Si) on the friction and wear was investigated. Various surface roughness average (Ra) of different degrees was verified as well ...
Preparation and characterization of Co-HA powder using modified electroless method
(Trans Tech Publications, 2014)
C0-HA composite produced by simple electroless deposition method was studied. From the particle size analysis by Malvern particles analyzer its shows that 19% increment in average of the particle size powder increase after ...
Sintering behavior and microstructure evolution of mechanically alloyed W–bronze composite powders by two-step ball milling process
(Elsevier, 2013-01)
The miscibility of W in Sn and Cu is extremely poor. Sintering of W–bronze composites to their full density is proved to be difficult. To tackle this problem, the ball milling process of the W–bronze powder mixture proposed ...
