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 ...
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 ...
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 ...
Organic dye degradation with TiO2 catalyst/AAO template in the presence of H2O2
(Trans Tech Publications, 2013)
In this study, anodic aluminum oxide (AAO) fabricated from phosphoric acid electrolyte at ambient temperature was used as the porous template, while a sol gel procedure was used for the preparation of the TiO2 sol with the ...
Effect of roughness of hypo-and hyper-eutectic Al-Si piston alloy on wear characteristics under lubrication
(Elsevier B.V., 2013)
The tribological behavior of tow Al-Si 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 ...
Tribological properties of WS2 nanoparticles lubricants on aluminum-silicon alloy and carbon steels
(Walailak University, 2013-06)
The rheological properties of nanometric tungsten disulphide (WS2) nanoparticles oil lubricants and its tribological performance with two hypereutectic Al-Si alloy and carbon steel are examined. These two oils are used to ...
Using gibbs standard state free energy and a power regulating device to predict and control the fabrication of nanoporous alumina
(VBRI press, 2013-12)
The basic concept of Gibbs standard state free energy predicts a favorable condition for both room and high temperature fabrication of nanoporous alumina in phosphoric acid electrolyte. The anodization of aluminum foil in ...
