Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, EarlyView.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Films of Ni–7 at% V, Pd, Pt and Ta–Si–N as diffusion barriers for copper on Bi2Te3 [PDF]
, 1998 Films of Ni–7 at% V, Pt, Pd, and Ta40Si14N46, each approximately 100 nm thick, were magnetron-deposited and interposed between about 250 nm thick copper overlayers and Bi2Te3 single-crystalline substrates.

Improved Current Densities in MgB2 By Liquid-Assisted Sintering
, 2005 Polycrystalline MgB2 samples with GaN additions were prepared by reaction of Mg, B, and GaN powders. The presence of Ga leads to a low melting eutectic phase which allowed liquid phase sintering and produces plate-like grains. For low-level GaN additions
