The role of hydrogeology to achieve the water security [PDF]

open access: yes, 2018
[Abstract] The concept of water security focuses on the objective of water management in society. However, in urban environments -where requirements related to water supply, floods, important rains, rising water tables, pollution problems, among others-,

XAFS and XEOL of tetramesityldigermene – An electronic structure study of a heavy group 14 ethylene analogue

open access: yesJournal of Physics: Conference Series, 2013
Digermene, the germanium analogue of ethylene, has a multiple bonding motif that differs greatly from that of alkenes and exhibits no pure σ or π type bonds. The electronic structure of digermenes is difficult to study experimentally due to their reactivity, and is computationally challenging because of their shallow potential energy surfaces.

µLaue diffraction and XEOL to study structure and light emission in materials

open access: yes, 2023
The emergence of disruptive functionalities in nitrides is strongly related to the growth and technology process controls, but also to the development of advanced characterization techniques with high spatial resolutions. Focused X-ray beams provide innovative solutions to analyze quantitatively and correlatively the strain and light emission by ...

Xeol studies of impurity core-valence luminescence in mixed rubidium caesium chloride crystals [PDF]

open access: yesJournal of Physical Studies, 2005
The impurity core valence luminescence (CVL) of Rb0.82Cs0.18Cl mixed crystals was monitored at the Cl K- and Rb L3-absorption edges using X-ray excited optical luminescence (XEOL) technique. It is found that XEOL spectrum at the chlorine K-edge is identical with the Cl K-absorption spectrum of pure RbCl.

Structure and mineralogy of a gold ore body of shear zone origin: the Fosas de Vila ore. La Coruña. Spain [PDF]

open access: yes, 1999
[Abstract] This paper studies a shear zone containing a gold-bearing milonitic body, in which, evidences of several mining works are still visible. The geometry of the structure is described, as well as the different evolutive stages of the milonitic ...
