TL;DR: In this article, bionanocomposite films of chitosan/montmorillonite (CS/MMT) activated with ginger essential oil (GEO) were produced and characterized in terms of their physical and morphological properties.
Journal ArticleDOI
Bionanocomposites of chitosan/montmorillonite incorporated with Rosmarinus officinalis essential oil: Development and physical characterization
Victor Gomes Lauriano Souza,João Pires,Patrícia Freitas Rodrigues,Andreia A. S. Lopes,Francisco Manuel Braz Fernandes,Maria Paula Amaro de Castilho Duarte,Isabel M. Coelhoso,Ana Luisa Fernando +7 more
TL;DR: In this paper, the physical properties of bionanocomposites based on chitosan (Ch) reinforced with different commercial nanoclays and further incorporated with rosemary essential oil (REO) were evaluated through mechanical and X-ray diffraction analyses.
Journal ArticleDOI
Influence of the deposition conditions on the gas sensitivity of zinc oxide thin films deposited by spray pyrolysis
TL;DR: In this article, the sensitivity to methane gas of zinc oxide thin films deposited by spray pyrolysis was investigated and it was found that using highly resistive (above 10 4 Ω cm) thin films and by performing the measurements at 200°C a sensitivity better than one order of magnitude was found to detect 2000 ppm of methane.
Journal ArticleDOI
Formation and crystallization of zinc borosilicate glasses: Influence of the ZnO/B2O3 ratio
A. T G Kullberg,Andreia A. S. Lopes,J. P B Veiga,Maria Margarida Rolim Augusto Lima,Regina da Conceição Corredeira Monteiro +4 more
TL;DR: In this article, the effect of the ZnO/B 2 O 3 molar ratio on the formation of crystalline phases within the glass matrix was investigated by means of differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM).
