High-pressure processing effects on microbiological stability, physicochemical ...
Lopes, Ana C.; Queirós, Rui P.; Pinto, Carlos A.; Casal, Susana; Delgadillo, Ivonne; Saraiva, Jorge A.; Inácio, Rita S.Nowadays, consumers are more aware of the effects of their diet on their health, and thus demand natural or minimally processed food products. Therefore, research has focused on processes that assure safe products without jeopardizing their nutritional properties. In this context, this work aimed to evaluate the effects of high-pressure processing (550 MPa/3 min/15 °C, HPP) on a fruit salad (composed of melon j...
Prediction of SLS parts properties using reprocessing powder
Lopes, Ana C.; Sampaio, Álvaro M.; Silva, Cátia Samanta Ribeiro; Pontes, A. J.Purpose: Owing to the operating principle of powder bed fusion processes, selective laser sintering (SLS) requires effective management of the mixture ratio of processed material previously exposed to the high temperatures of processing with new virgin material. Therefore, this paper aims to fully understand the effect that the successive reprocessing has in the powder material and to evaluate its influence on ...
Development of poly(vinylidene fluoride)/ionic liquid electrospun fibers for ti...
Dias, Juliana C.; Correia, D. C.; Lopes, Ana C.; Ribeiro, Sylvie Oliveira; Ribeiro, Clarisse; Sencadas, Vítor João Gomes Silva; Botelho, GabrielaElectroactive electrospun fiber mat composites based on poly (vinylidene fluoride) (PVDF) with 5 and 10% of 1-ethyl-3-methylimidazolium bis (trifluoromethanesulfonyl)amide ([C2mim][NTf2]) ionic liquid (IL) were developed for potential applications in the biomedical area. The morphology and polymer crystalline phase content of the fibers were evaluated as a function of the processing conditions. Hydrophobic rand...
Improving discrimination in the grading of rat mammary tumors using two-dimensi...
Lopes, Ana C.; Cova, Tânia F. G. G.; Pais, Alberto A. C. C.; Pereira, Jorge L. G. F. S. C.; Colaço, Bruno; Cabrita, António M. S.This work aims at characterizing rat mammary tumors induced by 7,12-dimethylbenz(a)anthracene (DMBA) and the respective malignancy potential, commonly graded with histopathology features grouped by intensity levels. Tumors were described over fourteen multiple ranged microscopic parameters and a comprehensive characterization of the histological patterns and their relation with tumor grade was carried out by pr...
