The role of carbon nanotubes on the stability of tetragonal zirconia polycrystals
(Elsevier, 2018-10)
The effect of single walled carbon nanotubes (SWNT) at zirconia grain boundaries on the stability of a tetragonal zirconia polycrystalline matrix has been explored in as–sintered composites and after low–temperature ...

Seasonal synchronization of sleep timing in industrial and pre-industrial societies
(Nature Research, 2019-05-01)
Artificial light has reshaped human sleep/wake cycle in industrial societies and raised concern on the misalignment of this cycle relative to the light and dark cycle. This manuscript contrasts sleep timing in extratropical, ...

Study of Phases Evolution in High-coercive MnAl Powders Obtained Through Short Milling Time of Gas-atomized Particles
(Elsevier, 2017)
Gas-atomized Mn54Al46 particles constituted nominally of only ε- and γ2-phases, i.e. no content of the ferromagnetic L10-type τ-phase, have been used to study the evolution of phases during short time of high-energy milling ...

Optimizing the homogenization technique for graphene nanoplatelet/yttria tetragonal zirconia composites: Influence on the microstructure and the electrical conductivity
(Elsevier, 2018-10-30)
3 mol% yttria tetragonal zirconia polycrystalline (3YTZP) ceramic composite powders with 10 vol% nominal content of graphene nanoplatelets (GNPs) were prepared using four different homogenization routines: dispersion of ...

Heteroatom framework distribution and layer charge of sodium Taeniolite
(Elsevier, 2018)
The most advanced applications of clays depend crucially on their hydration state and swelling is probably the most important feature of expandable 2:1 layered silicate. Sodium Taeniolite, Na-TAE, a swelling trioctahedr ...

Effect of the crystal chemistry on the hydration mechanism of swelling micas
(Elsevier, 2017)
Swelling and dehydration under minor changes in temperature and water vapor pressure is an important property that clays and clay minerals exhibit. In particular, their interlayer space, the solid-water interface and the ...

Influence of magnetic interactions between phases on the magnetocaloric effect of composites
(AIP Publishing, 2013)
Magnetocaloric materials with coexisting magnetic phases appear either due to the phase coexistence in first order phase transitions, or due to the development of composites, which are known to enhance the refrigerant ...

The role of Ni in modifying the order of the phase transition of La(Fe,Ni,Si)(13)
(Elsevier, 2018)
In this work, we study the effect of Ni substitution on the magnetocaloric properties of La(Fe,Si)13 compounds. Sample quality has been optimized by a combination of induction melting and suction casting techniques, which ...
