Modelling of burnt pine heartwood acid-catalysed liquefaction
Ozkan, Sila; Gonçalves, Diogo; Paulo, Ivo; Queirós, Carla S. G. P.; Carvalho, Ana; Puna, Jaime; Gomes, João; Bordado, João; Santos, Rui Galhano dosThis study focused on bio-oil production by thermochemical liquefaction. For the reaction, the burnt pine heartwood was used as feedstock material, 2-Ethylhexanol (2-EHEX) was used as a solvent, p-Toluenesulfonic acid (pTSA) was used as a catalyst, and the solvent for washing was acetone. The procedure consisted of a moderate-acid-catalysed liquefaction process, and it was applied at three different temperature...
Development and In Vitro Validation of Antibacterial Paints Containing Chloroxy...
Querido, Micaela Machado; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Barbosa, Nuno; Gonçalves, Diogo; dos Santos, Rui GalhanoThe establishment of self-disinfecting surfaces is an important method to avoid surface contamination. Recently, paints with antimicrobial properties have been developed to be applied on different surfaces, avoiding contamination with pathogens. In this work, self-disinfecting paints containing Chloroxylenol (CLX), Terpineol (TRP), and a mixture of both substances were developed. The goal was to evaluate and va...
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 ...
Development of Self-disinfecting Paints and In Vitro Assessment of their Cytoto...
Querido, Micaela; Paulo, Ivo; Galhano Santos, Rui; Bordado, João; Teixeira, João Paulo; Pereira, CristianaThis PhD project aims to develop, test and validate a self-disinfecting paint, to be applied in areas with a high propensity for infection spreading, such as healthcare facilities, schools or other public spaces, to help reduce infection risks.
