Segregation Roasting for Copper Oxide Ore

Biological Synthesis of Copper/copper Oxide Nanoparticles

Metal nanoparticles have gained significant interest in the past decade because of their unique physio-chemical properties which has a potential to be used in a wide range of applications. Recent efforts have gained success in synthesising nanoparticles with excellent shape and size control; however they are largely restricted to chemical methods. There is an increasing focus on eco-friendly ‘g...

A simple method for the recovery of selenium from copper anode slime sample using alkaline roasting process

The recovery of selenium from Iranian sar-cheshmeh copper anode slime has been investigated. Copper anode slimes are containing varying precious metals, such as: gold, silver, selenium and tellurium. They are being extracted as a by-product in the production process. Arsenic and antimony that present in anode slimes dissolved in 0.4 M KOH. Then, the alkaline roasting of anode slimes in the pres...

Strontium oxide segregation at SrLaAlO4 surfaces

Grain boundary segregation in oxide ceramics

D PR O Abstract The factors which control grain boundary segregation in oxide ceramics are reviewed. These include grain boundary energy, cation–cation interactions, impurity cation size, as well as electrostatic interactions with the grain boundary space charge. In addition, an approach for measuring grain boundary segregation in those materials, as a function of the five macroscopic parameter...
