Victor Gomes Lauriano Souza,Ana Luisa Fernando,João Pires,Patrícia Freitas Rodrigues,Andreia A. S. Lopes,Francisco Manuel Braz Fernandes +5 more
TL;DR: In this paper, the incorporation of several natural antioxidants, both oil and water based, in the chitosan matrix and to evaluate the effect on the physical properties of the resulting biopolymers.
Journal ArticleDOI
Mathematical model coupling phase transformation and temperature evolution during quenching of steels
TL;DR: In this article, a mathematical model coupling phase transformations with temperature field predictions at each instant during the cooling process is proposed to calculate the internal stresses in steels during quenching.
Journal ArticleDOI

Elin Figueiredo,Rui J.C. Silva,João Carlos Senna-Martinez,M. Fátima Araújo,Francisco Manuel Braz Fernandes,João Luís Inês Vaz +5 more
TL;DR: In this article, a slag fragment from the emblematic Late Bronze Age habitat site of Castro da Senhora da Guia de Baioes (Viseu, Portugal) has been studied by optical microscopy, micro-EDXRF, SEM-EDS and XRD.
Journal ArticleDOI
Counterions in poly(allylamine hydrochloride) and poly(styrene sulfonate) layer-by-layer films.
João M.C. Lourenço,Paulo A. Ribeiro,Ana M. Botelho do Rego,Francisco Manuel Braz Fernandes,and Augusto M. C. Moutinho,M. Manuela M. Raposo +5 more
TL;DR: The ratio between the percentages of polyelectrolyte ionic groups lies close to unity for all samples, indicating that counterions do not contribute to charge compensation in the polyelectralyte during the adsorption process.
Journal ArticleDOI
