Phase transition in poly(vinylidene fluoride) investigated with micro-raman spectroscopy
Carlos J. L. Constantino,Aldo Eloizo Job,Rebeca Delatore Simões,José A. Giacometti,Valtencir Zucolotto,Osvaldo N. Oliveira,Giovani Gozzi,D. L. Chinaglia +7 more
TL;DR: Poling with negative corona discharge was found to affect the α-PVDF morphology, improving the Raman bands related to this crystalline phase, and corona-induced effects could not be observed with the other experimental techniques.

TL;DR: The insertion of the enzyme at DPPG monolayers caused an increase in the dynamic surface elasticity at 30 mN m(-)(1), indicating a strong interaction between the enzyme and lipid molecules at a high-surface packing.

Two-photon absorption in azoaromatic compounds
L. De Boni,José J. Rodrigues,D. S. dos Santos,Carlos Henrique Tomich de Paula da Silva,Débora Terezia Balogh,Osvaldo N. Oliveira,Sérgio Carlos Zílio,Lino Misoguti,Cleber Renato Mendonça +8 more
TL;DR: In this paper, the two-photon absorption (2PA) cross-sections of eight azoaromatic compounds in dimethyl sulfoxide solutions were obtained using the Z-scan technique with femtosecond laser pulses at 775 nm.

The morphology of layer-by-layer films of polymer/polyelectrolyte studied by atomic force microscopy
R. F. M. Lobo,Marcelo A. Pereira-da-Silva,M. Manuela M. Raposo,R M Faria,Osvaldo N. Oliveira +4 more
TL;DR: In this paper, the growth behavior of layer-by-layer (LBL) films of a semiconducting polymer (POMA) alternated with a polyelectrolyte (PVS), adsorbed onto silicon oxide, mica, ITO-glass, Au/Cr/glass, hydrophilic and hydrophobic glass were studied by atomic force microscopy (AFM).
