To increase renewable energy generation in some hydroelectric dams, a solution consisting in installing wind turbines close to dams is proposed. Indeed, dam surroundings are prone to benefit from wind speed-up effect, extra ...
Phase-field modelling of microstructural evolution in primary crystallization
(2007)
Article.
Accés obert
Article.
Accés obert
One of the main routes to obtain nanostructured materials is through the primary crystallization of metallic
glasses. In such transformations, crystallites with a different composition than the amorphous precursor grow
with ...

The amino acid lysine has been shown to prevent water crystallization at low temperatures in saturated aqueous solutions [S. Cerveny and J. Swenson, Phys. Chem. Chem. Phys., 2014, 16, 22382–22390]. Here, we investigate two ...
Analysis of the anelastic deformation of high-entropy Pd20Pt20Cu20Ni20P20 metallic glass under stress relaxation and recovery
(2022-04-30)
Article.
Accés obert
Article.
Accés obert
The anelastic deformation behavior of Pd20Pt20Cu20Ni20 P20 high-entropy metallic glass was probed by
monitoring the stress relaxation and recovery processes. The stress relaxation under consecutive strain
steps can be ...
Mixtures of m-fluoroaniline with apolar aromatic molecules: Phase behaviour, suppression of H-bonded clusters, and local H-bond relaxation dynamics
(2019-12-15)
Article.
Accés obert
Article.
Accés obert
We employ differential scanning calorimetry, IR spectroscopy, X-ray powder diffraction and dielectric spectroscopy to characterize binary mixtures of m-fluoroaniline (mFA), a rigid-molecule glass former, with two ...
Heat sink avalanche dynamics in elastocaloric Cu-Al-Ni single crystal detected by infrared calorimetry and Gaussian filtering
(2021-10-11)
Article.
Accés obert
Article.
Accés obert
The physics behind the cooling process occurring in an elastocaloric Cu–Al–Ni wire during the martensite to austenite transition after stress
release is studied. A previous experiment using infrared imaging determined the ...
Does the trihydrate of atorvastatin calcium possess a melting point?
(2020-05-30)
Article.
Accés obert
Article.
Accés obert
To decide whether an active pharmaceutical ingredient can be used in its amorphous form in drug formulations, often the glass transition is studied in relation to the melting point of the pharmaceutical. If the glass ...
Relaxation of internal friction and shear viscosity in Zr57Nb5Al10Cu15.4Ni12.6 metallic glass
(2020-09-01)
Article.
Accés obert
Article.
Accés obert
Relaxation of internal friction of Zr57Nb5Al10Cu15.4Ni12.6 metallic glass was investigated by mechanical spectroscopy. The stress relaxation of internal friction with different aging temperature was described by ...
Amorphous physics and materials: Secondary relaxation and dynamic heterogeneity in metallic glasses: A brief review

Article.
Accés obert
Article.
Accés obert
Understanding mechanical relaxation, such as primary (a) and secondary (ß) relaxation, is key to unravel the intertwined relation between the atomic dynamics and non-equilibrium thermodynamics in metallic glasses. At a ...
