Este artigo centra-se especificamente na utilização de nanomateriais (na forma de nanopartículas) para o desenvolvimento de “novas” misturas asfálticas no âmbito da pavimentação rodoviária. Para o efeito, misturas asfálticas convencionais foram modificadas através da utilização de nanopartículas de um semicondutor inorgânico (dióxido de titânio - TiO2) de modo a dotá-las de novas funcionalidades: capacidade fot...
The application of nanocoatings in the textile finishing is increasingly being explored because they open a whole new vista of value-addition possibilities in the textile sector. In the present work, low temperature pulsed DC magnetron sputtering method was used to create functional TiO2 nanocoatings on poly(lactic acid) textile fibres surfaces. In this study, the principal objectives in the application of TiO2...

poster ; Man’s activity and mismanagement of resources conducted to dangerous levels of pollution in water, air and earth and to incalculable deficiencies, harmful to the physical and social health of mankind. Industrial activities, heating systems and road traffic are the main responsibles for the emission of pollutant gases such as nitrogen oxides (NOx) and volatile organic compounds (VOCs). As so, its harmf...
