In this work, to prepare nanostructured and porous Fe/Pd–Fe bimetallic catalysts, the iron coating is applied firstly onto copper substrate by electrochemical deposition method. Subsequently, iron-zinc alloy deposited on underlayer iron. Eventually, immersing in an alkaline solution containing palladium ions, will replace zinc, resulting catalysts. The X-ray diffraction (XRD) technique was used...

The present work reflects the effects of trace addition copper (up to 1 wt.%) and zinc (0.5 on microstructure hardness property heat treated A356 (Al-7Si) alloy. Small amount was introduced into in both atomic form (alloy) powder (composite) its age hardening behaviour were investigated. To enhance wettability during composite fabrication solid solution strengthening alloys, a small quantity ma...

inspired multi-objective optimisation algorithm Jun Chena, Mahdi Mahfouf, Gaffour Sidahmed, doi:10.1016/j.engappai.2014.08.014 Highlights • We model mechanical properties of heat treated alloy steel using interpretable fuzzy models. • We demonstrate how to locate the ‘best’ processing parameters and chemical compositions. • We demonstrate how to achieve certain mechanical properties. • We demon...

This work assesses the use of modified natural natrolite zeolite as an adsorptive material for the separation and preconcentration of trace amounts of ions. In this work we investigated the potential of modified natural natrolite zeolite for the simultaneous separation and preconcentration of trace amounts of copper and zinc ions. We have developed a simple, rapid, selective, sensitive and econ...

AIM Remnants of provisional cement on the internal surface of cast restorations can have an adverse effect on the performance of the definitive luting agent. The purpose of this study was to evaluate the effect of eugenol-containing temporary cement removal by an ultrasonic or an organic solvent on the retentive strength of metallic rings cemented to amalgam cores using zinc phosphate cement. ...

The dezincification of brasses has been the subject of substantial conjecture and investigation over the past century and the technical press is littered with papers on the problem. Very broadly the technical literature can be subdivided into five main groups as follows: (a) Observations of dezincification phenomena including mechanically induced dezincification and in-service experience in var...

This paper examines the impact of fire on microstructural, mechanical, and corrosion behavior wire-arc-sprayed zinc, aluminum, Zn-Al pseudo-alloy coatings. Steel plates coated with these materials were subjected to temperatures in increments 100 °C, starting from 300 °C progressing until failure. Microstructural characterization, microhardness, abrasion resistance, electrochemical impedance stu...
