Lead-cadmium oxyfluoride glasses and glass-ceramics
(Natl Inst Optoelectronics, 2002-09-01)
Glasses and glass-ceramics have been obtained in oxyfluoride systems involving lead and cadmium fluorides and one of the well-known glass former oxides SiO2, B2O3 and TeO2. Vitreous domains were established and a wide range ...
Enhancement of mechanical properties of metallic glass nanolaminates via martensitic transformation: atomistic deformation mechanism
(Elsevier, 2019)
Metallic glasses with embedded crystalline phases have been experimentally reported to exhibit enhanced
mechanical properties. To further explore this observation, we employed molecular dynamics simulations to
study ...
Influence of metallic nanoparticles on electric-dipole and magnetic-dipole transitions of Eu(3+) doped germanate glasses
(AMER INST PHYSICS, 2010)
Luminescence properties of Eu(3+) doped germanate glasses containing either silver or gold nanoparticles (NPs) were investigated for excitation at 405 nm. Enhanced emissions and luminescence quenching of the Eu(3+) transitions ...
Enhanced optical properties of germanate and tellurite glasses containing metal or semiconductor nanoparticles
(2013-05-13)
Germanium- and tellurium-based glasses have been largely studied due to their recognized potential for photonics. In this paper, we review our recent studies that include the investigation of the Stokes and anti-Stokes ...

Tensile behavior of Cu50Zr50 metallic glass nanowire with a B2 crystalline precipitate
(Elsevier, 2018)
A molecular dynamics study of the effect of a single B2–CuZr precipitate on the mechanical properties of Cu50Zr50
metallic glass nanowires is presented. Four different samples are considered: three with a 2, 4 and 6 nm ...
Studies in sol-gel glasses with incorporation of Cu and Fe, using PAS, X-ray diffraction and EPR
(Kluwer Academic PublDordrechtHolanda, 2000)
Design of Fe-based bulk metallic glasses for maximum amorphous diameter (Dmax) using machine learning models
(Elsevier Science, 2021-02-15)
The development of bulk metallic glasses (BMGs) is a topic of current interest due to the unique set of properties that distinguish them from their crystalline counterpart and make them attractive in industrial applications ...
The influence of transition metal oxides type M+/M++ on the vanadium-tellurite glasses electrical behavior
(Elsevier Science, 2015-11)
In this work, the electrical behavior and structural features of the system xCu2O (1-x) (0.5V2O5·0.5MoO3) 2TeO2 compared to xAg2O (1-x) (0.5V2O5·0.5MoO3) 2TeO2 (which was already studied) are explored. The main goal is to ...
Onset of plasticity and its relation to atomic structure in CuZr metallic glass nanowire: A molecular dynamics study
(Elsevier Ltd, 2016)
© 2015 Elsevier B.V. All rights reserved.We present a computational tensile test which shows the evolution of the atomic structure of a Cu50Zr50 metallic glass nanowire at 300 K as the applied strain increases. The system ...
