Polyamorphic transitions in Ce-based metallic glasses by synchrotron radiation
(2011-12-01)
Article
Open AccessWe report here on a polyamorphic-phase transition upon application of pressure on a Ce-based metallic glass, Ce70Al10Ni10Cu10, investigated by x-ray diffraction and inelastic x-ray scattering. This alloy is found to display ... -
Link between shear modulus and enthalpy changes of Ti16.7Zr16.7Hf16.7Cu16.7Ni16.7Be16.7 high entropy bulk metallic glass
(2020-02-29)
Article
Restricted access - publisher's policyMechanical and thermal properties of materials are intricately linked. Particularly, this fully applies to metallic glasses. In this work, we study shear modulus behavior and heat effects occurring upon heating up of ... -
Azo-dye degradation by Mn–Al powders
(2020-03-15)
Article
Restricted access - publisher's policyManganese–Aluminum powders were recently reported to show high efficiency and fast reaction rates as decolorization materials for azo-dye aqueous solutions. This work presents a detailed study of different aspects of this ... -

Influence of modifier oxides on spectroscopic features of Nd2O3 doped PbO-Ro2O3-WO3-B2O3 glasses (with Ro2O3 = Sb2O3, Al2O3, and Bi2O3)
(2020)
Article
Restricted access - publisher's policyThe influence of modifier oxides (Ro2O3 = Sb2O3, Al2O3, and Bi2O3) on the spectral analysis of PbO-Ro2O3-WO3-B2O3 glasses doped with Nd3+ ions is investigated in this work. Samples were prepared by the melt quench method, ... -
Nose temperature and anticorrelation between recrystallization kinetics and molecular relaxation dynamics in amorphous morniflumate at high pressure
(2019-07-05)
Article
Restricted access - publisher's policyWe probe the dielectric response of the supercooled liquid phase of Morniflumate, a drug with anti-inflammatory and antipyretic properties, studying in particular the pressure and temperature dependence of the relaxation ... -
Dynamic mechanical relaxation in LaCe-based metallic glasses: influence of the chemical composition
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-17)
Article
Open AccessThe mechanical relaxation behavior of the (La0.5Ce0.5)65Al10(CoxCu1-x)25 at% (x = 0, 0.2, 0.4, 0.6, and 0.8) metallic glasses was probed by dynamic mechanical analysis. The intensity of the secondary ß relaxation increases ... -
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
Restricted access - publisher's policyWe 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 ... -
From tin- to antimony-based yellow opacifiers in the early Islamic Egyptian glazes: Regional influences and ruling dynasties
(Elsevier Ltd, 2019-08-01)
Article
Restricted access - publisher's policyA small group of opaque yellow glazed sherds has recently been identified among the ceramics excavated at the Islamic city of Madinat al-Zahra’ near Cordoba, in al-Andalus (southern Spain), which was founded in 936 AD ... -
Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol
(2019-04-18)
Article
Open AccessThere is currently great interest in replacing the harmful volatile hydrofluorocarbon fluids used in refrigeration and air-conditioning with solid materials that display magnetocaloric, electrocaloric or mechanocaloric ... -
Experimental and topological determination of the pressure-temperature phase diagram of racemic etifoxine, a pharmaceutical ingredient with anxiolytic properties
(2019-12-18)
Article
Restricted access - publisher's policyInformation about the solid-state properties of etifoxine has been lacking, even if the active pharmaceutical ingredient has been used for its anxiolytic properties for decennia. The crystal structure of the racemic compound ... -
Tuning molecular dynamics by hydration and confinement: Antiplasticizing effect of water in hydrated prilocaine nanoclusters
(Royal Society of Chemistry (RSC), 2019-01-01)
Article
Open AccessIn glass-forming substances, the addition of water tends to produce the effect of lowering the glass transition temperature, Tg. In a previous work by some of us (Ruiz et al., Sci. Rep., 2017, 7, 7470) we reported on a ...
