Pivotal role of Sb vacancies in quaternary half-Heusler thermoelectrics Open
The pivotal role of intrinsic defects in nominally stoichiometric X(Fe 0.5 Ni 0.5 )Sb quaternary half-Heuslers (X = Ti, Zr, or Hf) is revealed. The Sb vacancies naturally occur during synthesis and can alter the conduction behavior from n-…

Quantum Size Effect Exponential Heat Capacity in 4 nm Natural Nickel\n Nanolattice Open
Quantum size effect-induced heat capacity of metal nanoparticles at low\ntemperatures was predicted 79 years ago to be exponential. This, however, has\nnot been reported until date. In defiance, we demonstrate here observation of\nexponent…

Size-induced structural phase transition at ~6.0 nm from mixed fcc-hcp to purely fcc structure in monodispersed nickel nanoparticles Open
We have investigated the core issue of atomic lattices in monodispersed Ni nanoparticles (NPs) of sizes 3.8 nm to 10.1 nm using detailed analysis of X-ray diffraction, synchrotron radiation X-ray absorption spectroscopy (XAS) and magnetiza…
