Size-induced structural phase transition at ~6.0 nm from mixed fcc-hcp to purely fcc structure in monodispersed nickel nanoparticles
Tarachand, Vikash Sharma, Jaiveer Singh +5
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…
Quantum Size Effect Exponential Heat Capacity in 4 nm Natural Nickel Nanolattice
Tarachand Patel, Jaiveer Singh, Satya Sanmukharao Samatham +4
Quantum size effect-induced heat capacity of metal nanoparticles at low temperatures was predicted 79 years ago to be exponential. This, however, has not been reported until date.…
Influence of surfactants on the electrical resistivity and thermopower of Ni nanoparticles
Netram Kaurav, Gunadhor S. Okram, V. Ganesan
Compacted pellets of nanocrystalline nickel (NC-Ni) of average particle size ranging from 18 to 33 nm were prepared using a variety of surfactants. They were characterized well and…
Naturally self-assembled nickel nanolattice
Jaiveer Singh, Netram Kaurav, Niranjan Prasad Lalla +1
This is the first report on the critical nature of nanolattice formability of different particle size (~4-10nm) of monodispersed nickel nanoparticles. They exhibit strikingly hexag…
Lattice dynamics of MC60 compounds in FCC phase
K. Ranjan, N. Kaurav, Dinesh Varshney +2
Phonon dynamics of alkali metal atom, M doped in C60, forming MC60 solids in fcc phase has been studied. The calculations take into account Van-der-Waals and Coulomb interactions f…
