It was known for long that Ni-Al composite powders can be used to deposit self-bonding coating as a bond coat common ceramic coatings due the exothermic reaction between Ni and Al. However, it found with commercial large particle size, is difficult ignite self-propagating Al form intermetallics by plasma spraying. In this study, powder particles of different sizes were prepare intermetallics-ba...

The catalytic performance of electrocatalyst is straightforwardly determined by their surface and/or near-surface atomic configuration. Hence, uncovering the relationship between structure and at scale imperative for rational design proton exchange membrane fuel cells (PEMFCs) electrocatalysts. In this work, firstly, we present a general method preparation clean structurally ordered PdFe interm...

A pressure-induced phase transition of Mg₂Sr intermetallics from the low-pressure C14-type phase to an orthorhombic phase (space group Cmcm, Z = 4) at a high pressure of 21.0 GPa was firstly predicted using first-principles calculations combined with unbiased swarm structure searching techniques. The phase transition was identified as a first-order nature with a volume drop of 4.7%, driven by t...

Fundamental structural building principles are discussed for all 56 known intermetallic phases with approximately 400 or more atoms per unit cell and space-group symmetry F43m, Fd3m, Fd3, Fm3m or Fm3c. Despite fundamental differences in chemical composition, bonding and electronic band structure, their complex crystal structures show striking similarities indicating common building principles. ...
