Clean forest—project concept and early results
Gomes, João; Puna, Jaime; Marques, António; Gominho, Jorge; Lourenço, Ana; Galhano dos Santos, Rui; Ozkan, SilaThe Clean Forest project aims to valorize forest biomass wastes (and then prevent their occurrence as a fuel source in forests), converting it to bioenergy, such as the production of 2nd generation synthetic biofuels, like bio-methanol, bio-DME, and biogas, depending on the process operating conditions. Valorization of potential forest waste biomass thus enhances the reduction of the probability of occurrence o...
Self-Disinfecting Paints with the Natural Antimicrobial Substances: Colophony a...
Querido, Micaela Machado; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Barbosa, Nuno; Galhano dos Santos, Rui; Bordado, João MouraThe risk of infection arising from indirect sources-namely, contaminated surfaces-has been proved, particularly in healthcare facilities. In the attempt to minimize this problem, innumerable research projects involving the development of surfaces with self-disinfecting properties are being conducted. In this work, wall-paints with self-disinfecting properties were developed with the scope of being applied in en...
Auto-Disinfectant Acrylic Paints Functionalised with Triclosan and Isoborneol -...
Machado Querido, Micaela; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Pereira, Cristiana Costa; Barbosa, Nuno; Bordado, João MouraEnvironmental surface contamination with microorganisms is a serious concern worldwide. Triclosan and isoborneol present good antimicrobial activity. Their immobilisation to paint substrates allows for development of a material that stays effective over a longer time. In this work, we disclosed the preliminary studies to evaluate the antimicrobial activity of the active molecule after being functionalised with ...
Acrylamide mitigation in bakery products
Jesus, Susana; Delgado, Inês; Brandão, Carlos; Galhano dos Santos, Rui; Castanheira, IsabelThe aim of this study was the determination of acrylamide in Portuguese bakery and its reduction in a bakery product. Acrylamide is considered by the International Agency for Research on Cancer as a carcinogenic compound to animals and probably to humans. For this study a total of 30 samples of god bread, “trouxa filó”, pies, ham and cheese rollings, muffins, pastels, and cookies were randomly collected in seve...
Acrylamide mitigation in rye and oat bread
Jesus, Susana; Delgado, Inês; Brandão, Carlos; Galhano dos Santos, Rui; Castanheira, IsabelBackground and objective(s):Acrylamide is a carcinogenic substance for animals and to humans. The harmful effect of such compound was later confirmed, and recently the acrylamide was considered a neurotoxic and genotoxic substance1. This contaminant has been found in carbohydrate-rich foods since 20022. There are many studies regarding several mitigation strategies, however it is need to change the manufacturin...
