Microstructure, thermal and mechanical response of AZ51/Al2O3 nanocomposite with 2 wt.% Ca addition
( Elsevier, Ltd , 2013 , Article)In the present study, new AZ51/Al2O3–2Ca magnesium nanocomposite was successfully synthesized by simultaneously adding 2wt.% aluminum, 2wt.% Ca and 1.5vol.% nanosized Al2O3 (50nm) into AZ31 matrix using a disintegrated ... -
Modelling of the flow behaviour of wrought aluminium alloys at elevated temperatures by a new constitutive equation
( Elsevier, Ltd , 2014 , Article)The hot working behaviour of an Al–0.7%Mg–0.4%Si (wt.%) aluminium alloy has been investigated by torsion testing in the 450–575°C temperature range. The behaviour of the alloy, in terms of equivalent stress vs equivalent ... -
Nanocomposite Membranes of Silica and Polysulfone for Improved Gas Permeation
( Elsevier, Ltd , 2012 , Conference Paper)Polysulfone-Silica mixed matrix hybrid membranes have been prepared by incorporating silicon dioxide nanoparticles with average particle size of 136 nm. Two types of polysulfone-silica nanocomposite membranes were prepared ... -
Novel paclitaxel formulations solubilized by parenteral nutrition nanoemulsions for application against glioma cell lines
( Elsevier, Ltd , 2016 , Article)The aim of this study is to investigate using nanoemulsion formulations as drug-delivery vehicles of paclitaxel (PX), a poor water-soluble anticancer drug. Two commercially available nanoemulsion fat formulations (Clinoleic ... -
Severe plastic deformation of tubular AA 6061 via equal channel angular pressing
( Elsevier, Ltd , 2016 , Article)Various severe plastic deformation (SPD) processes have been developed to produce metal tubes with ultrafine grain (UFG) structures. However, most techniques are complex and limited to working with components that are short ... -
Synthesis and properties of electrodeposited Ni–B–CeO2 composite coatings
( Elsevier, Ltd , 2014 , Article)Ni–B coatings are extremely hard and wear resistant with decent anticorrosion properties which make them suitable for automotive, aerospace, petrochemical, plastic, optics, nuclear, electronics, computer, textile, paper, ... -
Thermal and mechanical properties of injection molded recycled high density polyethylene blends with virgin isotactic polypropylene
