Positron annihilation studies on chemically synthesized FeCo alloy
(Nature Publishing, 2018-06-27)
Equiatomic flower-like FeCo magnetic nanoparticles are synthesized through a modified one-pot polyol technique. The as-prepared samples are annealed at 700 and 800 degrees C under reducing atmosphere. The saturation ...
Charge transfer in Pr-Doped cerium oxide: Experimental and theoretical investigations
(2020-07-15)
In this study was synthesized cerium oxide (CeO2) doped with praseodymium (Pr) using a microwave-assisted hydrothermal method. The positions of the vacancies with respect to Ce3+/Ce4+ and the vacancy-like defects surrounded ...
Precipitation kinetics in Al-Zn-Mg commercial alloys

Decoration of Buried Surfaces in Si detected by Positron Annihilation Spectroscopy
(American Institute of Physics, 2006-12)
The terminations of buried surfaces of two different cavity types (nano- and microcavities) produced in the same He+-H+ co-implanted p-type Si (100) sample annealed at 900 °C, are studied and characterized by positron ...
Positron annihilation in triphenylphosphine oxide complexes: Positronium inhibition mechanism involving excitation of charge transfer states
(Elsevier Science BvAmsterdamHolanda, 2008)
Interstitial oxygen related defects and nanovoids in Au implanted a-SiO2 glass depth profiled by positron annihilation spectroscopy
(IOP Publishing, 2015-11)
Samples of amorphous silica were implanted with Au ions at an energy of 190 keV and fluences of 1×1014 ions cm−2and 5×1014 ions cm−2 at room temperature. The damage produced by ion implantation and its evolution with the ...
Intermolecular interactions on amine-cured epoxy matrices with different crosslink densities. influence on the hole and specific volumes and the mechanical behavior
(John Wiley & Sons Inc, 2009-07)
The architecture of an epoxy matrix was modified by curing the resin with mono-/diamine mixtures having identical chemical structures. Both hole volume and specific volume variations were studied by positron annihilation ...
Charge transfer in Pr-Doped cerium oxide: Experimental and theoretical investigations
(Elsevier Science SA, 2020-07)
In this study was synthesized cerium oxide (CeO2) doped with praseodymium (Pr) using a microwave-assisted hydrothermal method. The positions of the vacancies with respect to Ce3+/Ce4+ and the vacancy-like defects surrounded ...
Comparative study of thermal, mechanical and structural properties of polybutadiene rubber isomers vulcanized using peroxide
(Elsevier, 2016-07)
Three commercial polybutadiene rubber (BR) compounds (high cis, medium cis and high vinyl content) were vulcanized at 433 K, using different amounts of dicumyl peroxide (DCP) as curing agent. To analyze the structural ...
Influence of the Empty Space and the Internal Stresses on the Dielectric Strength in Two-Phase Polymer
(Institute Of Electrical And Electronics Engineers, 2013-10)
In the present work, a study on the dependence of the Dielectric Strength (DS) as a function of the empty space and the internal stresses into polymer samples has been performed. The empty space was measured by means of ...
