Otimização de amplificadores híbridos RAMAN+EDFA utilizando reciclagem de bombeamento
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2010-11-30)
In this work different configurations of hybrid amplifiers are studied, made by a Raman amplifier followed by an EDFA. Such amplifiers can be used to increase the transmission capacity in WDM based optical communication ...
The investigation of α→β phase transition in poly(vinylidene fluoride) (PVDF)
(2005-12-01)
The phase transition from the non-polar α-phase to the polar β-phase of poly(vinylidene fluoride) (PVDF) has been investigated using micro-Raman spectroscopy, which is advantageous for being a non-destructive technique. ...

Studies on the resonance Raman spectra of polyaniline obtained with near-IR excitation
(JOHN WILEY & SONS LTD, 2008)
The effects of near-IR (NIR) laser power over the Raman spectra of poly(aniline) emeraldine salt (PANIES) and base (PANI-EB) were investigated. The reasons for the existence of several bands from 1324 to 1500 cm-1 in the ...
