A hidden low-temperature transformation pathway in compositionally complex materials
Yujiao Li, Elaheh Akbarnejad, Quentin Bizot +9
Most compositionally complex materials (CCMs, frequently referred to as high entropy alloys) are metastable and their attractive properties often belong to kinetically trapped stat…
Conditional spinodal decomposition in Li-Mg anodes for lithium metal batteries
Leonardo Shoji Aota, Aubin Leray, Yuqi Liu +14
The development of batteries with high energy density, short charging times and use of sustainable materials is critical for decarbonization. Magnesium (Mg)-based anodes for lithiu…
High-strength and ductile lightweight cast aluminium alloys with superlattice nano-layered fibres (SNL) and core-shell nano-particles
Hemant Kumar, Praveen Kumar, Dierk Raabe +2
Lightweight, high-strength structural materials are component enablers in transportation and aerospace, reducing carbon footprints and enhancing fuel efficiency. Cast aluminium all…
Understanding early stages of low-temperature hydrogen-driven direct co-reduction of Fe-Ni mixed oxide thin films at the near atomic scale
Emmanuel Uwayezu, Shaolou Wei, Yujiao Li +3
Kinetic understanding of hydrogen co-reduction of multinary and multi-phase oxides is of interest for enhancing sustainability of alloy production and transition to a hydrogen-base…
Controlling Metastability through Annealing of High-Entropy Nanoalloy Electrocatalysts to Boost Performance towards the Oxygen Evolution Reaction
Varatharaja Nallathambi, Aneeta Jose Puthussery, Andrea M. Mingers +7
Low-cost transition metal high-entropy nanoalloys are emerging as sustainable alternatives to platinum group electrocatalysts. Synthesis conditions of single-phase solid solutions…
Kinetically controlling surface atom arrangements in thermally robust, amorphous high-entropy alloy nanoparticles by solvent selection
Varatharaja Nallathambi, Se-Ho Kim, Baptiste Gault +3
