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…
Specimen preparation for atom probe tomography analysis of complex multifunctional nanoparticles and nanostructures: state-of-the-art and challenges
Varatharaja Nallathambi, Se-Ho Kim, Nikita Polin +4
Atom probe tomography (APT) provides the three-dimensional composition of materials at near-atomic length scales, achieving detection limits in the range of tens of atomic parts-pe…
Kinetically controlling surface atom arrangements in thermally robust, amorphous high-entropy alloy nanoparticles by solvent selection
Varatharaja Nallathambi, Se-Ho Kim, Baptiste Gault +3
The ability to tailor nanoscale surface atom arrangements through multi-elemental compositional control provides high-entropy nanoalloys with promising functional properties. Devel…
Electric Field-Induced Formation of a 2D Adatom Gas on Cryogenic Li Surfaces
Shyam Katnagallu, Huan Zhao, Se-Ho Kim +3
Intense electrostatic fields, such as those able to break bonds and cause field-ion emission, can fundamentally alter the behaviour of atoms at and on the surface. Using density fu…
Understanding High Coercivity in ThMn12-Type Sm-Zr-Fe-Co-Ti Permanent Magnet Powders through Nanoscale Analysis
Nikita Polin, Alexander M. Gabay, Chaoya Han +6
ThMn12-type (Sm,Zr)1(Fe,Co,Ti)12 compounds show great potential for permanent magnets. Magnetically hard anisotropic powders prepared via reduction-diffusion exhibit a significant…
