The mechanisms of shear band initiation and propagation in amorphous metallic alloys is an open question of materials science. Here, the authors measure local strains around propagating shear bands and propose a model describing the plasticity of metallic glasses at different length scales. ...
In the case of bimetallic complexes with different nominal bond orders of formula M2(formamidinate)4, the metal–metal interaction is associated to a large electron fluctuation between the two metallic cores and interpreted in terms of simple resonance arguments. Such fluctuation between metals can ...
One promising class of metallic materials are the newly developed ("high-entropy”) multi-principal element alloys alloys (MPEAs)53,54,55,56,57,58. In particular, refractory MPEAs offer the opportunity to maintain high-temperature properties while, for example, decreasing density and oxidation kin...
Notably, Pt nanoparticles decorated with Co single atoms afford the selective cleavage of the C–O(H) bond in guaiacol and other lignin derivatives adjacent to an etheric C–O(R) bond with ether selectivities of >72.1%, and also work extensively for various other substrates with different ...

films are metallic as well within both DFT (Fig. 2f) and DFT + DMFT (Fig. 2g): the calculations exhibit nonzero spectral weights of Ni e g orbitals at the Fermi energy. However, the metallic state of the 1 u.c. film is marked by a very narrow bandwidth (mass renormalization ...
Metal bond strength regulation enables large-scale synthesis of intermetallic nanocrystals for practical fuel cells Although structurally ordered intermetallic nanocrystals are promising electrocatalysts for fuel cells, their high-temperature large-scale preparation has proved challenging. A low-melting-point-met...
