Anelastic relaxation due to OH pairs in NbZr alloys
(Elsevier B.V., 1994-09-01)
In the last 30 years several studies have been made to understand the relaxation mechanisms of the hydrogen atoms present in transition metals and their alloys. In this work, we observed the stress-induced ordering of ...
Solar variablity of the daytime atomic oxygen O(¹S) emission in the middle and lower thermosphere.
(The American Geophysical Union, 2004-03-13)
[1] The Wind Imaging Interferometer (WINDII) on board the Upper Atmosphere Research Satellite (UARS) measures winds from the Doppler shifts of airglow emissions, and as a by-product the volume emission rates (photon cm־³ ...
Anelastic relaxation due to OH pairs in NbZr alloys
(Elsevier B.V., 2014)
A model for the stabilization of atomic hydrogen centers in borate glasses
(ELSEVIER SCIENCE BV, 2009)
A previously proposed model describing the trapping site of the interstitial atomic hydrogen in borate glasses is analyzed. In this model the atomic hydrogen is stabilized at the centers of oxygen polygons belonging to B-O ...
Internal friction measurements in Nb-0.3wt.%Ti containing oxygen
(Editions Physique, 1996-12-01)
Internal friction measurements were made in the Nb-Ti alloy containing 0.3 wt. % of Ti, doped with various quantities of oxygen (0.04 to 0.08 wt. %) utilizing a torsion pendulum. These measurements were performed in the ...

Local atomic structure in tetragonal pure ZrO2 nanopowders
(Wiley Blackwell Publishing, Inc, 2010-04)
The local atomic structures around the Zr atom of pure (undoped) ZrO 2 nanopowders with different average crystallite sizes, ranging from 7 to 40 nm, have been investigated. The nanopowders were synthesized by different ...
