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 ...

Scratch, Fretting, and Sliding Wear of a ZrB2–hardened Zr3Al2 Intermetallic–ceramic Composite
(Elsevier, 2023)
The unlubricated wear behaviour of a very recently developed ZrB2–hardened Zr3Al2 intermetallic–ceramic composite was investigated for the first time. In particular, tribological tests of scratch, fretting, and sliding ...

Effect of Substitution of Rare Earth by Mischmetal on the Devitrification Process of Al-X-Ni-Co (X = Y, Ce, Mm) Alloys
(Elsevier, 2005)
The effect of substitution of Ce or Y by mischmetal (Mm) on the glass transition and the kinetics of crystallization of quaternary Al-Ni-Co-(Ce, Y, Mm) alloys was studied using isothermal and non-isothermal calorimetry and ...

Contrast sensitivity function under three light conditions in patients with type 1 diabetes mellitus without retinopathy: a cross-sectional, case–control study
(Springer Nature, 2023-09)
Purpose: To determine whether patients with type 1 diabetes mellitus (T1DM), without any sign of diabetic retinopathy, have any alteration in Contrast Sensitivity Function (CSF), in relation to patients without this disease, ...
