Tuning the mechanical integrity and corrosion performance of open-cell copper foams: identification of an optimization threshold

Abstract In this work, Porous copper foam samples were fabricated by a space-holder technique with water-atomized copper powder and sodium chloride (NaCl) particles in weight fractions ranging from 10 to 35 wt%. The powders were mechanically mixed at a 10:1 ball-to-powder ratio a...

The Effect of Pre-oxidation on the Hydrogen Reduction of Magnetite Ores at 973 K: Role of Particle Size and Gangue Chemistry

This study systematically investigates the effects of controlled pre-oxidation on hydrogen-based reduction of three industrial magnetite ores, distinguished by their gangue chemistries (CaO, negligible gangue, and MgO), and examines two particle size fractions. Pre-oxidation beha...
