Vilarinho, F.; Stanzione, M; Buonocore, G; Vaz, F; Silva, A.S.Eco-friendly and antioxidant bioactive films based on polylactic acid (PLA), loaded with cellulose nanocrystals (CNC) and green tea extract (GTE) were prepared by direct melt processing. GTE was chemically characterized by using high performance liquid chromatography (HPLC), coupled with tandem mass spectrometry. The antioxidant, physical, thermal, mechanical and microstructural properties of the produced films...
Nanocais: uma alternativa aos consolidantes tradicionais
Girginova, Penka; Galacho, Cristina; Mirão, José; Veiga, R; Silva, A.S.; Candeias, AntónioOs suportes de argamassa de pintura mural estão sujeitos a ameaça permanente de deterioração e envelhecimento causada pelas condições climáticas e pela poluição. A conservação das argamassas constituintes, sem remoção do material original, pode ser efetuada através do uso de consolidantes. Em termos de propriedades e de composição os consolidantes à base de cal, na sua forma tradicional, são convenientes mas nã...
