Giant enhancement of phonon-assisted one-photon excited frequency upconversion in a Nd3+-doped tellurite glass
(2013-02-07)
Changing the sample's temperature from 200 K to 535 K, we observed 670-fold enhancement of a phonon-assisted upconversion emission at ≈754 nm obtained from a Nd3+-doped tellurite glass excited by 5 ns laser pulses at 805 ...

Transition from nonradiative to radiative oscillons in parametrically driven systems
(American Physical Society, 2020)
Nonequilibrium systems exhibit particle-type solutions. Oscillons are one of the best-known localized states of systems with time-dependent forcing or parametrically driven systems. We investigate the transition from ...
Dusty spirals triggered by shadows in transition discs
(EDP Sciences, 2019)
Context. Despite the recent discovery of spiral-shaped features in protoplanetary discs in the near-infrared and millimetre wavelengths, there is still an active discussion to understand how they formed. In fact, the spiral ...
Dependence of transition probabilities for non-linear photo-ionization of He atoms on the structure of the exciting radiation pulses
(Sociedade Brasileira FisicaSao PauloBrasil, 2005)
A brief review on the high-energy electromagnetic radiation-shielding materials based on polymer nanocomposites
(MDPI, 2021)
This paper revises the use of polymer nanocomposites to attenuate high-energy electromagnetic radiation (HE-EMR), such as gamma radiation. As known, high-energy radiation produces
drastic damage not only in facilities or ...
Evaluation of weather influence on mechanical and viscoelastic properties of polyetherimide/carbon fiber composites
(2013-06-01)
In order to investigate how environmental degradation affects the mechanical and thermal performance of polyetherimide/carbon fiber laminates, in this work different weathering were conducted. Additionally, dynamic mechanical ...
