Alloying–realloying enabled high durability for Pt–Pd-3d-transition metal nanoparticle fuel cell catalysts

open access: yesNature Communications, 2020
Alloying noble metals with non-noble metals enables high activity while reducing the cost of electrocatalysts in fuel cells. However, under fuel cell operating conditions, state-of-the-art oxygen reduction reaction alloy catalysts either feature high ...

The Effects of Nanostructure on the Hydrogen Sorption Properties of Magnesium-Based Metallic Compounds: A Review

open access: yesCrystals, 2018
In this review, I examine the influence of nanoscale materials features on the hydrogen-metal interaction. The small system size, the abundance of surfaces/interfaces, and the spatial distribution of phases are the key factors to understand the hydrogen ...

Out-of-plane ordering in quaternary MAX alloys: an alloy theoretic perspective

open access: yesMaterials Research Letters, 2018
This letter is motivated by an apparent paradox, in that some quaternary systems (particularly in the Ti–Zr–Al–C system) have been shown to exhibit M-site out-of-plane ordering, while prior work and calculations by the present authors suggest endothermic

Metal protection against atmospheric corrosion

open access: yesVojnotehnički Glasnik, 1997
The procedures of metal protection against atmospheric corrosion are described in this paper. The protection can be achieved by choice of metals, alloying, some structural measures, protective coatings and the treatment of corrosion environments.
