Electron-Deficient Multicenter Bonding in Phase Change Materials: A Chance for Reconciliation
Autor: Francisco Javier Manjón, Hussien H. Osman, Matteo Savastano, Ángel Vegas
Publikováno v: Materials, Vol 17, Iss 12, p 2840 (2024)
In the last few years, a controversy has been raised regarding the nature of the chemical bonding present in phase change materials (PCMs), many of which are minerals such as galena (PbS), clausthalite (PbSe), and altaite (PbTe). Two opposite bonding

Aplicación de la teoría de juegos de estrategia al problema de la integración de riesgos
Autor: Ángel Vegas Pérez
Publikováno v: Económica, Vol 12, Iss 36 (1966)
The aim of this work is to define a "model of decision" with to the integration of risk units. The model lies on the definition of risk unit as the result of the economic effects of inauspiciousness and the probability of failure starting from an eco

Modelos estructurales de cristales inorgánicos. De los elementos a los compuestos
Autor: Ángel Vegas Molina
Publikováno v: Repositorio Institucional de la Universidad de Burgos (RIUBU)

Unique thermodynamic relationships for Δf H o and Δf G o for crystalline inorganic salts. I. Predicting the possible existence and synthesis of Na2SO2 and Na2SeO2
Autor: Ángel Vegas, Joel F. Liebman, H. Donald Brooke Jenkins
Publikováno v: Acta Crystallographica Section B Structural Science. 68:511-527
The concept that equates oxidation and pressure has been successfully utilized in explaining the structural changes observed in the M 2S subnets of M 2SO x (x = 3, 4) compounds (M = Na, K) when compared with the structures (room- and high-pressure ph

Reversible phase transitions in Na2S under pressure: a comparison with the cation array in Na2SO4
Autor: Michael Hanfland, Martin Jansen, Ingo Loa, Ángel Vegas, Andrzej Grzechnik, K. Syassen
Publikováno v: Acta Crystallographica Section B Structural Science. 57:151-156
The structural behavior of the antifluorite Na2S, disodium sulfide, has been studied under pressure up to 22 GPa by in situ synchrotron X-ray diffraction experiments in a diamond anvil cell at room temperature. At approximately 7 GPa, Na2S undergoes
