Deformation Behaviors in Single BCC‐Phase Refractory Multi‐Principal Element Alloys under Dynamic Conditions

open access: yesAdvanced Science, EarlyView.
Exceptional mechanical stability of refractory multi‐principal element alloy (RMPEA) across various strain‐rates and temperature is studied through multiscale experiments coupled with theoretical calculations. This stability originates from competition between twinning and adiabatic heating during dynamic deformation, contributed from severe lattice ...

Impact of Controlled Magneto‐Structural Coupling in MnCoGe‐Based Compounds on the Design of Multifunctional Materials for Technological Advances

open access: yesAdvanced Science, EarlyView.
In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...

Metallic Bond Induces Soft Phonon Mode and Anharmonicity in Heusler Alloy

open access: yesAdvanced Science, EarlyView.
The fruitful functional performances of metastable Heusler alloys originate from the martensitic transformation driven by the transverse acoustic soft phonon mode, regulated by anharmonicity. This study reveals that the long‐range interaction rooted in metallic bonding between spin‐down d‐orbitals of Ni─Ni induces phonon softening and significant ...

On the Design of Effective Water‐Soluble Actinide‐Masking Ligands Through Ligand Structure Modulation

open access: yesAdvanced Science, EarlyView.
Ligand topology and non‐coordination atoms are proved to be important for the design of effective water‐soluble actinide masking agents. Abstract Water‐soluble actinide‐masking ligands are fundamentally important for achieving efficient lanthanide/actinide separation and for the development of water‐soluble f‐block complexes for bioimaging and ...
